POSSIBLY EFFECTIVE

• Influenza. Although some small clinical studies show that elderberry extracts can improve influenza symptoms in otherwise healthy adults, a small clinical study enrolling adults and children with or without high risk medical conditions shows it does not reduce the duration of symptoms. Details: Small clinical studies in otherwise healthy adults with influenza presenting within 48 hours of symptom onset show that taking elderberry extract syrup (Sambucol, Nature's Way) 15 mL four times daily for 5 days improves patient ratings of symptoms such as aches and pains, cough, and nasal congestion an average of 4 days earlier than in control groups. It also reduced the use of rescue medications (5260,12235). Another small clinical study in adults shows that taking an elderberry extract lozenge (ViraBLOC, HerbalScience) 175 mg four times daily for 2 days, starting within 24 hours of symptom onset, improves flu-like symptoms, typically within 48 hours, when compared with placebo (17022). However, in a small clinical study in children and adults 5 years and older with influenza, including those with high-risk conditions such as asthma, chronic lung disease, and heart disease, using Sambucol for 5 days starting within 48 hours of symptom onset did not reduce the time to complete resolution of symptoms for a 24-hour period when compared with placebo (103831). These negative findings may be due to the age and baseline health status of the enrolled patients, as well as the use of symptom resolution, as opposed to symptom improvement, as the primary outcome. Elderberry has also been evaluated in combination with echinacea for treating influenza symptoms (95650), but it is not clear whether the combination is better than either ingredient alone.

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Allergic rhinitis (hay fever). Although there is interest in using oral elderberry for allergic rhinitis, there is insufficient reliable information about the clinical effects of elderberry for this purpose.
• Asthenopia (eye strain). Oral elderberry extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults without dry eye disease with occupations requiring the use of video display terminals shows that taking a specific combination product containing elderberry fruit extract 300 mg, zinc 10 mg, L-carnitine 50 mg, currant 100 mg, and Eleutherococcus root 50 mg (Meramirt CM) once daily for 1 month improves measures of eye strain and contrast sensitivity when compared to baseline. Improvements in these measures were lacking in the control group (111295). Statistical comparison between the two groups was not reported. It is unclear if these effects are due to elderberry, other ingredients, or the combination.
• Cardiovascular disease (CVD). It is unclear whether elderberry has any benefit in CVD. In one small study it did not alter disease markers. Details: Preliminary clinical research in postmenopausal women shows that taking elderberry extract 500 mg daily for 12 weeks does not significantly improve markers of CVD, including inflammatory biomarkers, vascular activity, or plasma lipid or glucose levels, when compared with placebo (21141).
• Chronic obstructive pulmonary disease (COPD). Elderberry has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in men aged 40-70 years with a history of smoking and Stage 2 COPD, shows that a combination of elderberry 165 mg, heart's ease herb 165 mg, and calendula flowers 165 mg (Inflaminat, INAT-Farma), 3 capsules daily for 6 months modestly improves the score on the 5-point breathlessness, cough, and sputum scale (BCSS) and modestly increases the mean forced expiratory volume in 1 second (FEV1), compared with no changes in the placebo group. However, the number of COPD exacerbations per month is not affected (103629). It is unclear if these effects are due to elderberry, the other ingredients, or the combination.
• Chronic fatigue syndrome (CFS). Although there has been interest in using oral elderberry for CFS, there is insufficient reliable information about the clinical effects of elderberry for this purpose.
• Cognitive function. Oral elderberry extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in healthy adults shows that consuming a multi-ingredient beverage containing elderberry extract 50 mg, carob extract, green tea powder, and guarana seed extract improves some measures of cognitive function such as rapid visual information processing and multitasking 120 minutes later when compared with placebo (113940). It is unclear if this effect is due to elderberry, other ingredients, or the combination.
• Common cold. Oral elderberry extract does not seem to PREVENT colds when taken prophylactically, but it may reduce the duration and severity of existing colds. Details: Clinical research in healthy adults shows that taking capsules containing elderberry extract (BerryPharma, Iprona AG) 600 mg daily for 8 days before overseas air travel, and then 900 mg daily starting 1 day before traveling and continuing for 4-5 days after arriving at the destination, does not reduce the number of colds or impact quality of life when compared with placebo. However, this product does reduce the duration of colds by about 2 days and the severity of colds by about 58% when compared with placebo (91374).
• Constipation. Oral elderberry extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial among airline flight crew shows that taking a specific product (ACTIVE) containing elderberry extract 70 mg and a specific probiotic formulation (SYNBIO) daily for 1 month improves constipation, stool volume and consistency, ease of defecation, intestinal regularity, flatulence, and diarrhea compared to baseline, but not when compared with placebo (112134). It is unclear if these effects are due to elderberry, the probiotics, or the combination.
• Gingivitis. Elderberry has been evaluated as a mouthwash or patch in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that using a mouth rinse (HM-302, Izun Pharmaceuticals) containing elderberry, echinacea, and gotu kola 15 mL three times daily for 14 days might prevent worsening of gingivitis when compared with a placebo rinse. However, it only minimally improves symptoms (20069). Other preliminary clinical research shows that applying a periodontal patch (PerioPatch, Izun Pharmaceuticals) containing elderberry, echinacea, and gotu kola either as a single dose, or three times daily for 1 day then once daily for 2 days, reduces some, but not all, measures of inflammation and gingivitis when compared with no treatment (20068,20070).
• HIV/AIDS. Although there has been interest in using oral elderberry for HIV/AIDS, there is insufficient reliable information about the clinical effects of elderberry for this purpose.
• Hyperlipidemia. It is unclear if elderberry is beneficial for the treatment of hyperlipidemia. Details: One preliminary clinical study in patients with hyperlipidemia shows that taking capsules containing spray-dried elderberry 400 mg, providing 10% anthocyanins, three times daily for 2 weeks does not reduce serum lipids when compared with placebo (21142).
• Lower respiratory tract infections. Oral elderberry extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in children aged 2-6 years with recurrent respiratory tract infections shows that adding a specific combination product (Stimunex gocce) containing elderberry extract, beta-glucans, zinc, and vitamin D3 to standard therapy does not reduce the number or duration of lower respiratory tract infections when compared with standard therapy alone. In the four months after treatment completion, the number of infections was reduced by about 50%; however, the total number of infections in each group was small. The dose was 1 drop/kg daily for one month, followed by 1 drop/kg daily for 15 consecutive days each month for the next three months (109212). The validity of this study is limited by lack of blinding.
• Obesity. Elderberry has been studied for weight loss in combination with other ingredients; its effect when used alone is unclear. Details: Observational research in overweight adults shows that replacing all meals for 8 days with a kit containing elderberry juice (from 120 grams of elderberries/day), dried elderberry (225 mg/day), dried elderflower (3.9 grams/day), elderflower extract (600 mg/day), and dried asparagus (40.5 grams/day), while also taking psyllium 2-3 teaspoons daily for 2 weeks, is associated with a mean decrease in body weight of 3.2 kg over 14 days when compared with baseline (94939). The validity of this study is limited by the lack of a comparator group. Also, it is unclear whether this effect is due to elderberry, other ingredients, the combination, or fasting from regular food.
• Psychological well-being. Oral elderberry has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial among airline flight crew shows that taking a specific product (ACTIVE) containing elderberry extract 70 mg and a specific probiotic formulation (SYNBIO) daily for 1 month improves scores on the Psychological General Well Being Index when compared with placebo. The index measures symptoms of anxiety and depression, general health status, and feelings of vitality and general self-control (112134). It is unclear if these effects are due to elderberry, the probiotics, or the combination.
• Respiratory tract infections. Oral elderberry has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in children aged 2-6 years with recurrent respiratory tract infections shows that adding a specific combination product (Stimunex gocce) containing elderberry extract, beta-glucans, zinc, and vitamin D3 to standard therapy reduces the duration of respiratory tract infections by about 1.7 days and modestly improves parent-perceived symptom severity when compared with standard therapy alone. However, there was no effect on the number of total, upper, or lower respiratory tract infections, the use of antibiotics or antipyretics, or the number of days missed from school. The product was dosed as 1 drop/kg daily for one month, followed by 1 drop/kg daily for 15 consecutive days each month for the next three months (109212). The validity of this study is limited by lack of blinding.
• Rhinosinusitis. Although there has been interest in using oral elderberry for rhinosinusitis, there is insufficient reliable information about the clinical effects of elderberry for this purpose.
• Upper respiratory tract infection (URTI). Oral elderberry has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in children aged 2-6 years with recurrent respiratory tract infections shows that adding a specific combination product (Stimunex gocce) containing elderberry extract, beta-glucans, zinc, and vitamin D3 to standard therapy does not reduce the number or duration of upper respiratory tract infections when compared with standard therapy alone. At four months after treatment completion, the number of infections was reduced by about 44%; however, the total number of infections in both groups was small. The product was dosed as 1 drop/kg daily for one month, followed by 1 drop/kg daily for 15 consecutive days each month for the next three months (109212). The validity of this study is limited by lack of blinding. More evidence is needed to rate elderberry for these uses.

IMMUNOSUPPRESSANTS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Theoretically, elderberry might interfere with immunosuppressant therapy due to its immunostimulant activity.  Details Elderberry has immunostimulant activity, increasing the production of cytokines, including interleukin and tumor necrosis factor (10796).

PAZOPANIB (Votrient) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, elderberry might interact with pazopanib, potentially increasing the risk of adverse effects.  Details In one case, a 65-year-old patient taking pazopanib for 4 weeks for soft-tissue sarcoma developed severe nausea, loose stools, and elevated alanine transaminase and aspartate transaminase levels and was diagnosed with grade 3 liver injury. The patient reported taking elderberry supplements for 2 years, dose unspecified, and was also taking a multivitamin and a calcium supplement. The patient's symptoms and liver enzyme levels improved upon discontinuation of pazopanib and all supplements. Pazopanib treatment was re-initiated, at a lower dose, with no further evidence of liver injury. It was unclear in this case report if the elderberry supplements were derived from the berry, the flower, or the combination (113939).

General ...Orally, elderberry extracts prepared from ripe fruit seem to be well tolerated.
Most Common Adverse Effects:
Orally: When adverse effects occur, they are likely due to ingestion of raw and unripe elderberries, or seeds, leaves, and other plant parts. Due to cyanogenic glycosides, these may cause nausea, vomiting, severe diarrhea, weakness, dizziness, numbness, and stupor. Cooking eliminates the toxin.

Gastrointestinal ...Orally, nausea and vomiting have been reported after consuming a specific elderberry and echinacea product Vogel Bioforce AG) (95650). However, it is unclear if this was due to the elderberry or Echinacea contained in the product.
Raw and unripe elderberries, and the seeds, leaves, and other elder tree parts might cause nausea, vomiting, or severe diarrhea due to cyanogenic glycosides (17020,17021). Cooking eliminates the toxin.

Hepatic ...In one case report, a 60-year-old female with underlying autoimmune disease presented with autoimmune hepatitis after taking elderberry at an unknown dose for several years. The patient presented with nausea, jaundice, abdominal pain, and abdominal distention. Liver function tests returned to baseline 4 weeks after initiating treatment with prednisone 40 mg daily and discontinuing elderberry (110123).

Immunologic ...Elder tree pollen might cause an allergic reaction characterized by rhinitis and dyspnea in some patients who are allergic to grass pollen. These patients might also experience an allergic reaction to elderberry extracts (11095).

Neurologic/CNS ...Raw and unripe elderberries might cause weakness, dizziness, numbness, and stupor due to cyanogenic glycosides (17020,17021). Cooking eliminates the toxin.
