• Constipation. Although there has been interest in using oral dandelion for constipation, there is insufficient reliable information about the clinical effects of dandelion for this purpose.
• Dyspepsia. Although there has been interest in using oral dandelion for dyspepsia, there is insufficient reliable information about the clinical effects of dandelion for this purpose.
• Flatulence. Although there has been interest in using oral dandelion for flatulence, there is insufficient reliable information about the clinical effects of dandelion for this purpose.
• Heart failure. Although there has been interest in using oral dandelion for its diuretic effects in patients with heart failure, there is insufficient reliable information about the clinical effects of dandelion for this purpose.
• Joint pain. Although there has been interest in using oral or topical dandelion for joint pain, there is insufficient reliable information about the clinical effects of dandelion for this purpose.
• Postoperative pain. It is unclear if topical dandelion is beneficial in patients with pain after jaw surgery. Details: A small clinical study in patients undergoing maxillofacial surgery shows that topical application of dandelion combined with borneol one time on the day of surgery and twice daily on the first and second days after surgery for 30 minutes does not reduce maxillofacial pain when compared with cold compresses or either ingredient alone (112484). The validity of this finding is limited by concurrent use of opioid analgesic and nonsteroidal anti-inflammatory medications.
• Postoperative swelling. It is unclear if topical dandelion is beneficial in patients with swelling after jaw surgery. Details: A small clinical study in patients who underwent maxillofacial surgery shows that topical application of dandelion combined with borneol one time on the day of surgery and twice daily on the first and second days after surgery for 30 minutes modestly reduces facial swelling and improves mouth opening abilities when compared with cold compresses or borneol alone (112484). It is unclear whether this effect is due to dandelion, borneol, or the combination.
• Tonsillitis. It is unclear if oral dandelion is beneficial in patients with tonsillitis. Details: One small clinical study in patients with acute purulent tonsillitis shows that eating soup containing dandelion (pugongying soup) daily for 3 days along with benzylpenicillin sodium 640,000 units daily improves recovery when compared with placebo plus benzylpenicillin sodium. Recovery rates were 36% with the dandelion-containing soup compared to 10% with placebo (18292).
• Urinary tract infections (UTIs). Oral dandelion has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in females with recurrent UTIs shows that taking a specific combination of dandelion root and uva ursi leaf extracts three times daily for 1 month reduces the risk of UTI recurrence when compared with placebo at 12-month's follow-up. For every 5 patients treated with this combination over placebo, one additional UTI was prevented (1932). In this combination, uva ursi is used for its antibacterial properties and dandelion is used to increase urination. However, this combination is not recommended for extended use because uva ursi may be unsafe when used long-term. Another small clinical study in premenopausal females with acute, uncomplicated lower UTIs shows that taking a combination product containing dandelion extract 50 mg, D-mannose, prebiotics, arabinogalactan, and astragalus root extract twice daily for five days, along with phenazopyridine and alkylating agents as conventional therapy, improves UTI symptoms and bacteriuria when compared with placebo plus conventional therapy (111757). It is unclear if these effects are due to dandelion, other ingredients, or the combination. More evidence is needed to rate dandelion for these uses.

• Diabetes. Oral jiaogulan extract powder may improve glycemic control in patients newly diagnosed with type 2 diabetes when used alone or with diabetes medications. Details: A meta-analysis of two small clinical trials in adults with newly diagnosed type 2 diabetes shows that taking jiaogulan whole plant extract powder, 1.5 grams dissolved in 60 mL of room temperature water, twice daily before meals for 8-12 weeks reduces glycated hemoglobin by 1%, fasting blood glucose by 29 mg/dL, and post-prandial blood glucose by 80 mg/dL when compared with green tea (111503). In one of the trials, both the jiaogulan and the placebo groups were also started on a sulfonylurea 4 weeks prior to the study and remained on it throughout the trial (95519). In the other trial no participants were taking diabetes medications (95520). Additionally, a very small cross-over trial that was not included in the aforementioned meta-analysis shows this same jiaogulan protocol reduces fasting blood glucose and improves insulin sensitivity at 4 weeks when compared with green tea in adults newly diagnosed with type 2 diabetes (94054). The washout period was 2 weeks, and switching to placebo reversed the improvements in glycemic control. All three clinical trials above were conducted in Vietnam by the same research group with the same jiaogulan extract product and protocol (94054,95519,95520). The validity of these findings may be limited by the use of a potentially non-inert green tea placebo, as green tea itself has been studied for its effects on preventing and treating diabetes.

• Cardiovascular disease (CVD). Although there has been interest in using oral jiaogulan for CVD, there is insufficient reliable information about the clinical effects of jiaogulan for this purpose.
• Hypercholesterolemia. Small clinical studies suggest that oral jiaogulan extract may lower cholesterol levels in patients with hypercholesterolemia. Details: Two small clinical studies in patients with hypercholesterolemia show that taking jiaogulan extract can decrease total cholesterol and increase the high-density lipoprotein (HDL)/total cholesterol ratio (7069,7070). The dose of jiaogulan extract used in one study was 10 mg three times daily (7069).
• Hypertension. Although there has been interest in using oral jiaogulan for hypertension, there is insufficient reliable information about the clinical effects of jiaogulan for this purpose.
• Memory. Although there has been interest in using oral jiaogulan for memory, there is insufficient reliable information about the clinical effects of jiaogulan for this purpose.
• Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral jiaogulan extract is beneficial in patients with NAFLD. Details: One small clinical study in patients with NAFLD shows that taking jiaogulan extract three times daily for 4 months in conjunction with controlled dieting does not improve markers of liver function, body mass index, cholesterol levels, kidney function, or glucose levels when compared with placebo (57056).
• Obesity. Small clinical studies suggest that oral jiaogulan extract may slightly reduce body weight in patients who are overweight or obese. Details: Two small clinical studies in adult patients who are overweight or obese show that taking jiaogulan extract 225 mg twice daily for 12-16 weeks reduces body weight by 1.3 kg and body mass index (BMI) by around 0.4 kg/m2 when compared with placebo (94058,106651).
• Respiratory tract infections. Although there has been interest in using oral jiaogulan for various respiratory tract infections, including bronchitis, rhinosinusitis, and the common cold, there is insufficient reliable information about the clinical effects of jiaogulan for these conditions.
• Stress. It is unclear if oral jiaogulan extract is beneficial in patients with chronic stress. Details: One small clinical study in healthy adults with self-perceived chronic stress and anxiety at baseline, but without a confirmed diagnosis of anxiety, depression, or other mental health disorders, shows that taking jiaogulan extract 200 mg twice daily for 8 weeks while being exposed to repetitive stressful tasks decreases anxiety scores by almost 17% when compared with placebo. While no subjective assessments of stress were included, salivary cortisol levels and other stress markers did not improve with jiaogulan when compared with placebo (100961). More evidence is needed to rate jiaogulan for these uses.

• Angina. Low-quality clinical research shows that oral or intravenous Panax notoginseng may improve the frequency and severity of angina symptoms. Details: Meta-analyses of low-quality clinical research in patients with angina shows that Panax notoginseng administered intravenously or orally 200-400 mg 2-3 times daily for 2-6 weeks, in addition to conventional medicine, increases the number of patients who achieve a 50% improvement in angina pectoris symptoms by approximately 1.2-fold when compared with conventional medicine alone (94321,94326,94378). Panax notoginseng also reduces angina attack frequency by about 2 attacks per week but does not reduce the incidence of intractable angina pectoris (94321).
• Intracranial hemorrhage. Low-quality clinical research shows that intravenous Panax notoginseng saponins may improve recovery and mortality in patients with intracranial hemorrhage. Details: A meta-analysis of low-quality clinical research in patients with intracranial or intracerebral hemorrhage shows that treatment with Panax notoginseng saponins 140-600 mg intravenously daily for 2-10 weeks increases the odds of improvement by 2.7-fold when compared with conventional treatment alone. A subgroup analysis also suggests that treatment within 48 hours reduces the risk of mortality by 55% when compared with conventional treatment alone (94324).
• Stroke. Low-quality clinical research in patients with ischemic stroke shows that oral or intravenous Panax notoginseng may improve recovery as well as neurologic and functional scores. Details: Three meta-analyses of clinical research in patients with ischemic stroke show that treatment with oral or injectable Panax notoginseng 150-1080 mg daily for 3 days to 6 months with or without standard treatment improves neurological status and increases the overall response rate and improvement rate by around 20% when compared with conventional medicine alone or control (94373,109523,112463). Treatment with Panax notoginseng also improved some measures of activities of daily living (109523,112463). Additionally, preliminary clinical research in patients with a recent anterior cerebral ischemic stroke shows that taking Panax notoginseng root (sanchitongtshu) extract, containing 100 mg of panaxatriol saponins, orally three times daily with aspirin 50 mg daily for 28 days improves neurological deficit scores and activities of daily living scores when compared with placebo and aspirin (17183). There is evidence that Panax notoginseng may benefit stroke sequalae beyond the acute period of symptoms. A very large clinical study in adults with mild to moderate ischemic stroke shows that taking Panax notoginseng saponins 60 mg twice daily for 3 months within 14 days of stroke symptom onset in addition to standard care increases the proportion of patients with functional independence at 3 months by 7%, the number of patients with no or minimal disability at 3 months and 12 months by 5% and 3%, respectively, and leads to greater improvements in neurological deficits and activities of daily living when compared with placebo. However, Panax notoginseng does not improve functional independence at 12 months or reduce the risk of recurrent stroke or composite cerebrovascular events when compared with placebo (112464).

POSSIBLY INEFFECTIVE

• Myocardial infarction (MI). Low-quality clinical research shows that oral Panax notoginseng may not reduce the risk of MI in patients with coronary heart disease. Details: A meta-analysis of two small clinical trials in patients with existing coronary heart disease shows that that taking a specific Panax notoginseng product (Xuesaitong soft capsule, Shenghuo Pharmaceutical Holdings) 240 mg orally twice daily along with conventional therapy for 4 weeks does not reduce the risk of MI when compared with conventional therapy alone (94321).

• Atherosclerosis. Although there has been interest in using oral Panax notoginseng for atherosclerosis, there is insufficient reliable information about the clinical effects of Panax notoginseng for this purpose.
• Athletic performance. It is unclear if oral Panax notoginseng is beneficial for improving athletic performance. Details: A meta-analysis of small clinical studies in generally healthy adults shows that taking Panax notoginseng 200-1350 mg or ginsenoside Rg1, a constituent of Panax notoginseng, 5 mg orally once daily for 1-30 days before running or cycling increases exercise endurance when compared with control (109672). One clinical study of untrained adults shows that taking Panax notoginseng root powder 1350 mg daily for 30 days increases cycling endurance by at least 7 minutes when compared with baseline (94384). The validity of this study is limited by the lack of a comparator group.
• Bleeding. Although there has been interest in using oral Panax notoginseng for bleeding, there is insufficient reliable information about the clinical effects of Panax notoginseng for this purpose.
• Bruises. Although there has been interest in using topical Panax notoginseng for bruises, there is insufficient reliable information about the clinical effects of Panax notoginseng for this purpose.
• Coronary heart disease (CHD). It is unclear if oral Panax notoginseng is beneficial for improving platelet aggregation and coagulation in patients with CHD. Details: A meta-analysis of clinical studies in patients with CHD and ischemic stroke shows that taking Panax notoginseng preparations including Panax notoginseng saponins (PNS) or panaxatriol saponins (PTS) with aspirin reduces platelet aggregation rate when compared with aspirin alone. Subgroup analysis suggests that the two formulations differ in their effect on biomarkers of platelet aggregation and coagulation. PTS increases prothrombin time and prothrombin time-based international normalized ratio (PT-INR) compared with aspirin alone. Meanwhile, PNS reduces fibrinogen and D-dimer compared with aspirin alone. Neither Panax notoginseng preparation changed platelet counts when compared with aspirin alone (112462).
• Exercise-induced muscle soreness. It is unclear if oral Panax notoginseng is beneficial for reducing exercise-induced muscle soreness. Details: Preliminary clinical research in well-trained males shows that taking Panax notoginseng, 4 grams orally one hour before a downhill run, then every 4 waking hours for 48 hours, and then twice daily for 48 hours, modestly reduces delayed onset muscle soreness at 96 hours, but not at earlier time points, when compared with baseline (94320). The validity of this study is limited by the lack of a comparator group.
• Hepatitis. Although there has been interest in using oral Panax notoginseng for hepatitis, there is insufficient reliable information about the clinical effects of Panax notoginseng for this purpose.
• Hypertension. Although there has been interest in using oral Panax notoginseng for hypertension, there is insufficient reliable information about the clinical effects of Panax notoginseng for this purpose.
• Nonalcoholic steatohepatitis (NASH). Although there has been interest in using oral Panax notoginseng for NASH, there is insufficient reliable information about the clinical effects of Panax notoginseng for this purpose.
• Osteoarthritis. Oral Panax notoginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with knee osteoarthritis shows that taking two capsules, each containing 400 mg of a combination of Panax notoginseng, Siberian ginseng, and rehmannia, orally daily for 6 weeks moderately improves physical function scores, but not pain or stiffness scores, when compared with placebo (74950). It is unclear if these effects are due to Panax notoginseng, other ingredients, or the combination.
• Rheumatoid arthritis (RA). Although there has been interest in using oral Panax notoginseng for RA, there is insufficient reliable information about the clinical effects of Panax notoginseng for this purpose.
• Ulcerative colitis. Rectal Panax notoginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults admitted to the hospital with mild to moderate ulcerative colitis lesions shows that administering a 1-gram suppository containing Panax notoginseng and multiple other ingredients rectally for 3 months improves diarrhea and bloody stool symptom scores when compared with a 0.8-gram suppository containing the same ingredients. Recurrence at 12 months occurred in approximately 10% of the patients who received the higher-dose combination product compared with 47% of patients who received the lower dose. Patients in each group received 2 suppositories twice daily for the first month, 1 suppository twice daily for the second month, and 1 suppository once daily for the third month. Each suppository contained Panax notoginseng 36 grams, cortex phellodendri 120 grams, radix Sanguisorbae 120 grams, arnebia root, 120 grams, radix pulsatillae 120 grams, rhizoma coptidis 120 grams, cortex fraxini 120 grams, rhizoma corydalis, pericarpium papaveris 72 grams, radix sophorae flavescentis 72 grams, and rhizoma bletillae 72 grams (109673). The interpretation of these results is limited by the lack of comparison to placebo or active control with known effectiveness for ulcerative colitis. Additionally, it is unclear if these effects are due to Panax notoginseng, other ingredients, or the combination.
• Venous thromboembolism (VTE). It is unclear if oral or intravenous Panax notoginseng is beneficial for the prevention of postoperative deep vein thrombosis (DVT). Details: A meta-analysis of randomized controlled trials in adults undergoing surgical treatment for a fracture shows that using a Panax notoginseng injection, alone or in combination with other anticoagulants, for 3-14 days reduces the risk of DVT by 58% when compared with active control, such as low-molecular weight heparin (LMWH) or rivaroxaban (105510). The validity of these findings is limited by the high heterogeneity of the included studies. A prospective study in post-surgical adults using LMWH shows that taking a specific Panax notoginseng tablet (Xuesaitong, Hunan Xiangya Pharmaceutical Company) 100 mg three times daily reduces the risk of DVT by 44% when compared with LMWH alone (109674). The validity of this study is limited by lack of randomization. More evidence is needed to rate Panax notoginseng for these uses.

• Aging skin. It is unclear if topical peony is beneficial in patients with aging skin. Details: Preliminary clinical research shows that using a cosmetic ingredient containing 0.5% paeoniflorin, a constituent of peony root, for 8 weeks can reduce facial wrinkles when compared with baseline (68356). The validity of this finding is limited by the lack of a comparator group.
• Anal fissures. Although there has been interest in using topical peony for anal fissures, there is insufficient reliable information about the clinical effects of peony for this purpose.
• Ankylosing spondylitis. Small, low-quality clinical studies suggest that oral peony, as total glucosides of peony (TGP), may improve disease symptoms in patients with ankylosing spondylitis. Details: A meta-analysis of 3 clinical trials in patients with ankylosing spondylitis (AS) shows that taking TGP 0.6 grams 3 times daily with conventional medical treatment for 12-24 weeks improves the AS disease activity score when compared with conventional treatment alone. TGP also improves inflammatory markers including erythrocyte sedimentation rate, C-reactive protein, tumor necrosis factor alpha, and interleukin-6 (112861). The reliability of these findings is limited by the low to very low quality of the included studies. Additionally, all of the studies were conducted in China; it is unclear if findings can be applied to other geographical regions and populations.
• Antipsychotic-induced hyperprolactinemia. Oral peony has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in females with risperidone-induced hyperprolactinemia shows that taking a specific combination of peony and licorice (Peony-Glycyrrhiza Decoction; PGD) 45 grams daily for 4 weeks is similarly effective to bromocriptine for reducing prolactin levels (59775). A similar trial in males with antipsychotic-induced hyperprolactinemia shows that taking an herbal extract containing peony and licorice (shakuyaku-kanzo-to), 2.5 grams three times daily, reduces prolactin levels after 4 weeks of treatment when compared with baseline. Prolactin levels returned to baseline 4 weeks after treatment cessation (59907). The validity of this study is limited by the lack of a comparator group. Subsequently, a higher quality clinical trial in females with antipsychotic-induced hyperprolactinemia shows that taking a peony and licorice decoction (PGD) 45 grams daily for 16 weeks does not improve prolactin levels or clinical symptoms when compared with placebo (97219). However, a small clinical trial in adults with schizophrenia and sexual dysfunction due to antipsychotic-induced hyperprolactinemia shows that taking a similar PGD formulation for 8 weeks improves sexual function scores and prevents further increases in prolactin levels when compared with a non-treated control group (112412). It is unclear if any effects are due to peony, licorice, or the combination.
• Atherosclerosis. Although there has been interest in using oral peony for atherosclerosis, there is insufficient reliable information about the clinical effects of peony for this purpose.
• Chronic fatigue syndrome (CFS). Although there has been interest in using oral peony for CFS, there is insufficient reliable information about the clinical effects of peony for this purpose.
• Cirrhosis. Although there has been interest in using oral peony for cirrhosis, there is insufficient reliable information about the clinical effects of peony for this purpose.
• Cough. Although there has been interest in using oral peony for cough, there is insufficient reliable information about the clinical effects of peony for this purpose.
• Dysmenorrhea. Although there has been interest in using oral peony for dysmenorrhea, there is insufficient reliable information about the clinical effects of peony for this purpose.
• Dyspepsia. Although there has been interest in using oral peony for dyspepsia, there is insufficient reliable information about the clinical effects of peony for this purpose.
• Diabetic nephropathy. It is unclear if oral peony is beneficial in patients with diabetic nephropathy. Details: Preliminary clinical research in Chinese adults with diabetic nephropathy shows that taking total glucosides of peony (TGP) 600 mg three times daily in conjunction with losartan 100 mg daily for 6 months does not improve urinary albumin excretion rate when compared with losartan alone. Taking TGP in conjunction with losartan also did not affect serum creatinine, fasting glucose, glycated hemoglobin (HbA1c), triglycerides, or total cholesterol when compared with losartan alone (98466).
• Epilepsy. It is unclear if oral peony is beneficial in patients with epilepsy. Details: Preliminary clinical research in children 1-14 years of age with intractable epilepsy shows that taking peony root extract orally 20 mg/kg twice daily for 4 weeks reduces weekly seizure frequency and average seizure duration by 80% and 83%, respectively, when compared with baseline. Approximately 63% of subjects reported a reduction in seizure frequency of at least 50% when compared with baseline. The validity of this study is limited by the lack of a comparator group (106851).
• Gout. Although there has been interest in using oral peony for gout, there is insufficient reliable information about the clinical effects of peony for this purpose.
• Hepatitis. Although there has been interest in using oral peony for hepatitis, there is insufficient reliable information about the clinical effects of peony for this purpose.
• Juvenile idiopathic arthritis (JIA). Small clinical studies suggest that oral peony, as total glucosides of peony (TGP), may modestly improve symptoms in patients with JIA. Details: A pooled analysis of low-quality clinical research in Chinese children 1.5-14 years of age with JIA shows that taking TGP 30-180 mg/kg daily or 600-1800 mg daily in conjunction with methotrexate for 9-26 weeks improves the odds of overall response rate by 1.5 to 2.5 times when compared with methotrexate alone. TGP also reduces erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels when compared with methotrexate alone. Preliminary subgroup analyses suggest that TGP is not effective for JIA if it is taken for 8 weeks or less (92785). Another meta-analysis of 7 small to moderate-sized clinical trials in children with JIA also shows that taking TGP 0.3 mg/kg, 30-60 mg/kg, or 1200 mg daily with conventional treatment for 12-24 weeks improves effectiveness rates when compared with conventional treatment alone. TGP also reduces ESR, CRP, and tumor necrosis factor alpha (TNF-α) (112861). The reliability of these findings is limited by the variability in the quality of the included studies. Additionally, all of the studies were conducted in China; it is unclear if findings can be applied to other geographical regions and populations.
• Mastalgia. Although there has been interest in using oral peony for mastalgia, there is insufficient reliable information about the clinical effects of peony for this purpose.
• Migraine headache. Although there has been interest in using oral peony for migraine, there is insufficient reliable information about the clinical effects of peony for this purpose.
• Muscle cramps. Oral peony has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary, low-quality, clinical research shows that taking a specific combination of peony and licorice (shakuyaku-kanzo-to) orally, 2.5-6 grams daily for up to 4 weeks, relieves muscle cramps when compared to baseline in patients undergoing hemodialysis (13551,13552). The validity of these studies is limited by the lack of a comparator group. It is also unclear if this effect is due to peony, licorice, or the combination.
• Neuropathic pain. Although there has been interest in using oral peony for neuropathic pain, there is insufficient reliable information about the clinical effects of peony for this purpose.
• Osteoarthritis. Some low-quality clinical studies suggest that oral peony, as total glucosides of peony (TGP), may modestly improve symptoms in patients with osteoarthritis. Details: A meta-analysis of 4 moderate-sized clinical trials in adults with osteoarthritis shows that taking TGP 0.6 grams 2 or 3 times daily with conventional medical treatment for 4-12 weeks improves joint pain when compared with conventional treatment alone (112861). The reliability of these findings is limited by the low quality and high heterogeneity of the included studies. Additionally, all of the studies were conducted in China; it is unclear if findings can be applied to other geographical regions and populations.
• Pancreatitis. It is unclear if rectal peony is beneficial in patients with pancreatitis. Details: Preliminary clinical research in adults with moderate to severe acute pancreatitis shows that rectal administration of 150 mL water containing 15 grams of red peony root granules twice daily for 7 days in addition to standard care reduces the time to resolution of abdominal pain and normal bowel habits by 25% when compared with a placebo enema. Additionally, patients receiving red peony root had an average 2-day reduction in hospital stay and a greater improvement on the modified Balthazar CT score when compared with placebo (104283).
• Polycystic ovary syndrome (PCOS). Oral peony has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research shows that taking peony root extract 2250 mg daily, along with Ceylon cinnamon, levant berry, St. John's wort, Tribulus, and licorice, during the follicular phase of the menstrual cycle for 3 months reduces the rate of oligomenorrhea or amenorrhea by 33% and the time between menstrual cycles by 43 days when compared with lifestyle modification alone. Taking this combination also improves quality of life by about 30% and modestly reduces body weight and body mass index when compared with lifestyle intervention alone. Although taking this combination improved conception rate by 4-fold, live birth rate was similar to lifestyle intervention alone (97216). It is unclear if these effects are due to peony, the other ingredients, or the combination.
• Premenstrual syndrome (PMS). Although there has been interest in using oral peony for PMS, there is insufficient reliable information about the clinical effects of peony for this purpose.
• Psoriasis. It is unclear if oral peony is beneficial for plaque psoriasis. Details: Preliminary clinical research in Chinese adults with moderate to severe plaque psoriasis shows that taking total glucosides of peony (TGP) 600 mg three times daily in conjunction with acitretin for 12 weeks does not improve plaque size or severity when compared with acitretin alone. However, taking TGP in combination with acitretin might increase the number of patients achieving a 50% reduction in plaque size when compared with acitretin alone (97950).
• Psoriatic arthritis. Small, low-quality clinical studies suggest that oral peony, as total glucosides of peony (TGP), may improve symptoms in patients with psoriatic arthritis. Details: A meta-analysis of 2 small clinical trials in adults with psoriatic arthritis shows that taking TGP 0.6 grams 3 times daily with conventional medical treatment for 12-24 weeks improves Psoriasis Area and Severity Index (PASI) scores and the inflammatory marker erythrocyte sedimentation rate when compared with conventional treatment alone (112861). The reliability of these findings is limited by the low quality and high heterogeneity of the included studies. Additionally, all of the studies were conducted in China; it is unclear if findings can be applied to other geographical regions and populations.
• Respiratory tract infections. Although there has been interest in using oral peony for respiratory tract infections, there is insufficient reliable information about the clinical effects of peony for this purpose.
• Restless legs syndrome (RLS). Oral peony has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of 12 low-quality clinical studies in Chinese patients with RLS shows that taking peony-containing combination herbal preparations along with conventional therapy appears to improve sleep quality and decrease RLS symptoms when compared with conventional therapy alone. A few of the studies included in this analysis also suggest that taking peony-containing herbal products alone might be more effective than conventional therapy for RLS (100991). The peony-containing products included in this analysis contained between 4-15 other herbal ingredients. It is unclear whether the effects are due to peony, other ingredients, or the combination.
• Rheumatoid arthritis (RA). It is unclear if oral peony is beneficial in patients with RA; evidence is conflicting. Details: Although low-quality clinical research in patients with RA has shown that use of total glucosides of peony (TGP) in conjunction with standard treatment for 4-24 weeks reduces inflammatory markers such as erythrocyte sedimentation rate and C-reactive protein when compared with standard treatment alone, effects on RA symptoms are conflicting (92786,101245,112861). A pooled analysis of clinical research in adults with RA shows that taking TGP in conjunction with leflunomide for 4-24 weeks is less effective for reducing RA symptom scores than taking leflunomide alone (92786). In contrast, another pooled analysis of clinical research in adults with RA shows that taking TGP for 12-24 weeks in combination with methotrexate improves swollen joint count, but not other symptoms such as morning stiffness and tender joint count, when compared with methotrexate alone. Preliminary subgroup analyses also suggest that taking TGP in conjunction with methotrexate might reduce overall adverse effects when compared with methotrexate alone (101245). Of note, the dose of TGP used is not reported in most trials included in these two analyses. Another meta-analysis of 10 mostly small to moderate-sized clinical trials in adults with RA shows that taking TGP 0.6 grams 1-3 times daily with conventional medical treatment for 12-48 weeks improves symptoms as evaluated with the Disease Activity of 28 joints (DAS28) scale when compared with conventional treatment alone (112861). However, these analyses are all limited by the low quality of the included studies. Additionally, all of the included studies were conducted in China; it is unclear if findings can be applied to other geographical regions and populations.
• Sjogren syndrome. It is unclear if oral peony is beneficial in patients with Sjogren syndrome. Details: Some clinical research in Chinese adults with Sjogren syndrome shows that taking total glucosides of peony (TGP) 600 mg three times daily for 24 weeks improves overall symptoms, with the greatest effects on symptoms of dry eye and fatigue, when compared with placebo (100992). An earlier and smaller clinical study from the same research group found that taking TGP at the same dose and duration improved symptoms of dry mouth, but did not reduce overall symptom scores or other markers of disease, when compared with placebo (97949). However, this study was not adequately powered to detect differences in overall symptom scores between TGP and placebo.
• Spasticity. Although there has been interest in using oral peony for spasticity, there is insufficient reliable information about the clinical effects of peony for this purpose.
• Systemic lupus erythematosus (SLE). Small clinical studies suggest that oral peony, as total glucosides of peony (TGP), may modestly improve disease activity scores in patients with SLE. Details: A meta-analysis of 13 small to moderate-sized, low-quality clinical studies in patients with SLE shows that taking TGP 0.6 grams 2-3 times daily or 1.2 grams twice daily for 1-6 months in conjunction with conventional treatment modestly improves the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score when compared with conventional treatment alone. Analyses of secondary endpoints which were not available for all studies show that TGP also improves markers of SLE disease activity, including erythrocyte sedimentation rate (ESR) and C-reactive protein, reduces the average daily dose of glucocorticoids and the cumulative dose of cyclophosphamide, and decreases the rate of disease recurrence (110432). However, the validity of the findings from this meta-analysis is limited by the heterogeneity of the included studies, which enrolled patients of varying age and disease severity. Additionally, a similar meta-analysis of 8 small to moderate-sized, low-quality clinical studies in adults with SLE shows that taking TGP 0.6 grams 2-3 times daily for 3-12 months in conjunction with conventional treatment of glucocorticoids and/or immunosuppressants improves SLEDAI scores when compared with conventional treatment alone. TGP also improves markers of inflammation such as ESR, levels of immunoglobulins A, G and M, and complement 3 and 4 (112862). The validity of these finding is also limited by substantial heterogeneity which may be due to differences in conventional therapies. In addition, all of the studies included in these meta-analyses were conducted in China; it is unclear if findings can be applied to other geographical regions and populations. More evidence is needed to rate peony for these uses.

• Atopic disease. Although there has been interest in using oral rehmannia for atopic disease, there is insufficient reliable information about the clinical effects of rehmannia for this purpose.
• Diabetes. Although there has been interest in using oral rehmannia for diabetes, there is insufficient reliable information about the clinical effects of rehmannia for this purpose.
• Diabetic nephropathy. Oral rehmannia has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A large clinical study in adults with chronic kidney disease due to type 2 diabetes receiving standard care with an angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker shows that taking a specific combination product (Rehmannia-6, PuraPharm) containing rehmannia, Japanese cornel dogwood, wild yam, poria mushroom, Asian water plantain, and peony root bark twice daily for 48 weeks modestly slows the decline in kidney function when compared with standard care alone (112821). It is unclear if this effect is due to rehmannia, other ingredients, or the combination.
• Metabolic syndrome. Although there has been interest in using oral rehmannia for metabolic syndrome, there is insufficient reliable information about the clinical effects of rehmannia for this purpose.
• Obesity. It is unclear if oral rehmannia root extract is beneficial in patients with obesity. Details: A very small clinical study in females with obesity shows that taking steamed rehmannia root extract 4 grams twice daily for 8 weeks decreases waist circumference by 2.6%, but does not affect body weight or body fat percentage, when compared to baseline (93660). The validity of these findings is limited by the lack of a control group.
• Osteoporosis. Although there has been interest in using oral rehmannia for osteoporosis, there is insufficient reliable information about the clinical effects of rehmannia for this purpose.
• Rheumatoid arthritis (RA). Although there has been interest in using oral rehmannia for RA, there is insufficient reliable information about the clinical effects of rehmannia for this purpose. More evidence is needed to rate rehmannia for these uses.

• Allergic rhinitis (hay fever). Although there has been interest in using oral skullcap for allergic rhinitis (hay fever), there is insufficient reliable information about the clinical effects of skullcap for this purpose.
• Anxiety. It is unclear if oral skullcap is beneficial for reducing symptoms of anxiety. Details: Preliminary clinical research shows that healthy people who take a single dose of freeze-dried skullcap extract 100-350 mg feel more relaxed when compared to baseline. This effect appears to last for about 2 hours (12216). However, other preliminary clinical research in healthy patients shows that taking freeze-dried skullcap (Skullcap, Eclectic Institute) 350 mg three times daily for 2 weeks does not reduce anxiety scores when compared with placebo (91690). Because these were short-term studies in healthy patients, it's unclear if skullcap is beneficial in anxiety disorders or if extended use is beneficial.

Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, peony might increase the levels and clinical effects of clozapine.  Details In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on cytochromes P450 (CYP) 1A2 and CYP3A4 (92790). This effect has not been reported in humans.

CONTRACEPTIVE DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, peony might interfere with contraceptive drugs due to competition for estrogen receptors.  Details In vitro and animal research shows that peony extract has estrogenic activity (100990). Concomitant use might also increase the risk for estrogen-related adverse effects.

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, use of peony may increase the levels and clinical effects of drugs metabolized by CYP1A2.  Details In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on CYP1A2 and CYP3A4 (92790). This effect has not been reported in humans.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, use of peony may increase the levels and clinical effects of drugs metabolized by CYP3A4.  Details In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on CYP1A2 and CYP3A4 (92790). This effect has not been reported in humans.

ESTROGENS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, concomitant use of large amounts of peony might interfere with hormone replacement therapy and/or increase the risk for estrogen-related adverse effects.  Details In vitro and animal research shows that peony extract has estrogenic activity (100990). Theoretically, peony might compete for estrogen receptors and/or cause additive estrogenic effects.

PHENYTOIN (Dilantin) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = D Theoretically, peony might reduce the levels and clinical effects of phenytoin.  Details Animal research shows that taking peony root reduces levels of phenytoin (8657). Some researchers suggest that peony root might affect cytochrome P450 (CYP) 2C9, which metabolizes phenytoin. However, preliminary research in humans shows that peony root does not alter levels of losartan (Cozaar), which is also metabolized by CYP2C9 (11480).

General ...Orally, dandelion seems to be well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, heartburn, and stomach discomfort.
Topically: Dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis in sensitive individuals.

Cardiovascular ...In one report, a 39-year-old obese woman developed palpitations and syncope after taking a weight loss supplement containing a combination of dandelion, bladderwrack, and boldo for 3 weeks. The patient was found to have prolonged QT-interval on ECG and frequent episodes of sustained polymorphic ventricular tachycardia (14321). It is not clear whether dandelion, another ingredient, or the combination of ingredients is responsible for this adverse effect. The product was not analyzed to determine the presence of any potential toxic contaminants.

Dermatologic ...Topically, dandelion can cause contact dermatitis and erythema multiforme in sensitive individuals. Dandelion can cause an allergic reaction in individuals sensitive to the Asteraceae/Compositae family (13478,13481,42893,46945,46977). Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs.

Endocrine ...In one report, a 56-year-old man with renal impairment developed hyperoxalaemia and peripheral gangrene after ingesting large amounts of dandelion tea (10 to 15 cups daily for 6 months). The adverse effect was attributed to the high oxalate content of dandelion tea (258 mcmol/L) and reduced renal oxalate clearance caused by renal impairment (90639). In another report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemic symptoms 2 weeks after beginning to eat salads containing dandelion (46960). The hypoglycemic effect was attributed to the potential alpha-glucosidase inhibitory activity of dandelion.

Gastrointestinal ...Gastrointestinal symptoms, including stomach discomfort, diarrhea, and heartburn, have been reported following oral use of dandelion (19146,36931). A case of intestinal blockage has been reported for a patient who ingested a large amount of dandelion greens three weeks after undergoing a stomach operation (46981). Also, a case of hemorrhagic cystitis has been reported for a 33-year-old woman who took a specific herbal product (Slim-Kombu, Balestra and Mech, Vicenza, Italy) containing 20 herbal extracts, including dandelion extract. Symptoms resolved after the patient discontinued using the product, and symptoms resumed when the patient began taking the supplement again four months later. While various ingredients in the supplement may have contributed to the symptoms, it is possible that dandelion extract may have contributed to the effect due to its diuretic, laxative, cholagogue, and antirheumatic properties (46959).

Other ...Orally, products containing dandelion pollen can cause allergic reactions, including anaphylaxis (13479,13480). Also, rhinoconjunctivitis and asthma have been reported after handling products such as bird feed containing dandelion and other herbs, with reported positive skin tests for dandelion hypersensitivity (46948). Dandelion pollen may cause pollinosis, such as allergic rhinitis and conjunctivitis (18065,46951,46964,46966,46972).

General ...Panax notoginseng seems to be generally well tolerated when used orally or intravenously.
Most Common Adverse Effects:
Orally: Dry mouth, flushed skin, insomnia, nausea, nervousness, rash, vomiting.
Intravenously: Headache, itching, rash.
Serious Adverse Effects (Rare):
Intravenously: Fever, pustular drug eruption.

Dermatologic ...Orally, Panax notoginseng can cause flushed skin (5558). When given orally or intravenously, rash has been reported (94321,94324,94326,94378,98976). There is a case of interstitial granulomatous drug reaction in a 73-year-old male who had been using oral Panax notoginseng extract for 2 months. The condition repeated after 5 days of intravenous use at a later time. The skin condition gradually cleared after use of the product was discontinued (94316). In a retrospective review of hospital records of 30,884 patients, a specific Xueshuantong injection (XSTI) containing Panax notoginseng saponins was associated with a 4% incidence of skin reactions, including redness, itching, and maculopapules (98976).

Gastrointestinal ...Orally and intravenously, Panax notoginseng can cause dry mouth, nausea, and vomiting (5558,94321,98976). In one case report, a patient developed a large submucosal hematoma extending from the hypopharynx to lower esophagus after taking one oral dose of an unknown quantity of Panax notoginseng and hirudin (109671). It is unclear if this event was due to Panax notoginseng, hirudin, or other factors.

Immunologic ...Intravenously, Panax notoginseng saponins have been associated with five cases of pustular drug eruption due to acute generalized exanthematous pustulosis. The skin eruption was associated with fever and an increased neutrophil count in some cases. Symptoms were deemed to be probably or likely due to the Panax notoginseng product (94327). In a retrospective review of hospital records of 30,884 patients, a specific Xueshuantong injection (XSTI) containing Panax notoginseng saponins was associated with a fever frequency of 0.2%, edema frequency of 0.1%, and anaphylactic reactions in 0.03% (98976).

Neurologic/CNS ...Orally, Panax notoginseng can cause nervousness and insomnia (5558). Intravenously, Panax notoginseng has been reported to cause headache (94326,94378). In a retrospective review of hospital records of 30,884 patients, a specific Xueshuantong injection (XSTI) containing Panax notoginseng saponins was associated with a headache frequency of 0.3% and paresthesia frequency of 0.1% (98976).

Most Common Adverse Effects:
Orally: Abdominal distension, anorexia, diarrhea, gastrointestinal discomfort, nausea.
Topically: Dermatitis.

Dermatologic ...Topically, peony has been reported to cause contact dermatitis (13555).

Endocrine ...Orally, a specific traditional Chinese medicine preparation called DDT has been reported to lower follicle-stimulating hormone (FSH) levels and increase estradiol levels. It is not known if this effect is due to peony or the other ingredients (48404). Another specific traditional Chinese medicine preparation, Toki-shakuyaku-san, has been reported to increase plasma progesterone levels in some patients. It is not known if this effect is due to peony or the other ingredients (15294).

Gastrointestinal ...Orally, peony and total glucosides of peony (TGP) have been reported to cause gastrointestinal discomfort, including abdominal distension, anorexia, diarrhea, and nausea, in some patients (13538,92785,97949,98466,100992). In one clinical study, diarrhea was reported in 5% of patients taking TGP 600 mg three times daily for 24 weeks versus 1% of patients taking placebo (100992).

Hematologic ...Orally, there is one case report of easy gum bleeding, epistaxis, and skin bruising with an international normalized ratio (INR) above 6 in a 61-year-old male who was previously stable on warfarin therapy. This patient had switched from one brand of quilinggao, a popular Chinese herbal product, to another brand 5 days prior. This product contained Fritillaria spp. (beimu), Paeonia rubra, Chinese peony (chishao), Lonicera japonica (jinyinhua), and Poncirus trifoliata (jishi). The patient's INR decreased to 1.9 after temporary withdrawal of warfarin therapy. Upon re-initiation of quilinggao, his INR increased to 5.2. It is not known if the increased INR is due to peony or the other ingredients (68343).

General ...Orally or by inhalation, Salvia divinorum can cause hallucinogenic effects. These include restlessness, hyperactivity, disorientation, loss of coordination, dizziness, slurred speech, altered perceptions, changes in perception of body temperature, personal detachment or distorted body ownership, fatigue, severe mood changes, and psychosis. Most of these effects resolve within 20 minutes; however, some effects might last longer (7350,7351,15820,72901,100001,100002).

Gastrointestinal ...Orally, Salvia divinorum can cause nausea (7350).

Neurologic/CNS ...Neurologic changes caused by Salvia divinorum are rapid, intense, and short-lived. Most evidence suggests a peak effect within 2 minutes following consumption by smoking, with a slower peak when consumed orally. Most symptoms cease within 20 minutes; however, the 'high' can last as long as 2 hours. Symptoms include headache, restlessness, hyperactivity, disorientation, loss of coordination, dizziness, slurred speech, altered perceptions, including auditory, visual, tactile, and kinesthetic hallucinations, a feeling of being pinned to the floor, changes in perception of body temperature, personal detachment or distorted body ownership, and fatigue. These effects are not sustained and follow-up assessments weeks later usually show no lasting negative effects (7350,7351,15820,100001,100002).

Psychiatric ...Psychiatric changes caused by Salvia divinorum are rapid, intense, and short-lived. Most evidence suggests a peak effect within 2 minutes following consumption by smoking, with a slower peak when consumed orally. Most symptoms cease within 20 minutes; however, the 'high' can last as long as 2 hours. Symptoms include disturbed reality and mood changes including both euphoria or extreme happiness and severe anxiety, fear, or panic (72901,100001,100002). Rarely, the use of Salvia divinorum has been associated with both acute and chronic psychotic episodes. Whether Salvia divinorum use was directly responsible for these episodes is not yet clear. Some individuals were using cannabis or other recreational drugs concurrently and/or were possibly at increased risk of schizophrenia. However, these risk factors were not consistent, and the episodes occurred following the use of Salvia divinorum in all cases (100002). Salvia divinorum appears to have a low potential for abuse (100001).

General ...There is currently a limited amount of information available on the adverse effects of skullcap.
Most Common Adverse Effects:
Orally: Cognitive impairment, digestive disturbances, sedation.

Gastrointestinal ...Orally, mild digestive disturbances were reported in around 9% of patients taking skullcap 350 mg three times daily for 2 weeks (91690).

Hepatic ...There are four reports of hepatotoxicity associated with products thought to contain skullcap. However, it is uncertain whether the products actually contained skullcap. It is thought that the products might have been contaminated with an adulterant such as germander (515), which is known to cause liver damage.

Neurologic/CNS ...A single skullcap extract dose of 100 mg does not seem to have adverse CNS effects. However, a higher dose of 200 mg might cause sedation and cognitive impairment (12216). One patient taking skullcap 350 mg three times daily for 2 weeks reported vivid dreams (91690). It is unclear if this event was associated with skullcap.
