• Asthma. Oral anise has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in adults with allergic asthma shows that drinking one cup of tea prepared with multiple ingredients, including anise, twice daily for 6 months reduces sleep discomfort, cough frequency, and cough intensity when compared with placebo (19056). It is unclear if these findings are due to anise, other ingredients, or the combination.
• Constipation. Oral anise has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A very small crossover trial in patients with constipation shows that taking an herbal tea containing a combination of anise, fennel, elderberry, and senna daily for 5 days can decrease colon transit time, increase the number of daily evacuations, and improve the perception of bowel function when compared with placebo (49494). It is unclear if these findings are due to anise, other ingredients, or the combination.
• Depression. It is unclear if oral anise oil is beneficial in patients with depression. Details: A small clinical study in adults with mild to moderate depression and irritable bowel syndrome (IBS) shows that taking enteric-coated anise oil 200 mg three times daily for 4 weeks improves symptoms of depression by an additional 28% when compared with placebo and an additional 32% when compared with peppermint (94947).
• Diabetes. It is unclear if oral anise seed powder is beneficial in patients with diabetes. Details: A small clinical study in adults with type 2 diabetes shows that taking anise seed powder 5 grams daily for 60 days decreases fasting blood glucose levels by 36%, total cholesterol levels by 7.5%, and triglyceride levels by 15% when compared to baseline. Fasting blood glucose significantly increased in the control group, and total cholesterol and triglyceride levels were relatively unchanged (94953).
• Dysmenorrhea. Although there has been interest in using oral anise for dysmenorrhea, there is insufficient reliable information about the clinical effects of anise for this purpose.
• Dyspepsia. It is unclear if oral anise powder is beneficial in patients with dyspepsia. Details: A small clinical study in adults with postprandial distress syndrome shows that taking anise powder 3 grams three times daily for 4 weeks improves quality of life and symptoms of functional dyspepsia when compared with placebo. Of the evaluated symptoms, improvement was seen in all categories when compared to placebo except for nausea and vomiting, which were present in less than 5% of patients at baseline (94944,94945).
• Irritable bowel syndrome (IBS). It is unclear if oral anise oil is beneficial inpatients with IBS. Details: A small clinical study in adults with IBS shows that taking enteric-coated anise oil 200 mg three times daily for 4 weeks eliminates IBS symptoms in 75% of patients, compared with 53% of patients taking peppermint oil and 35% taking placebo. The greatest symptom improvement occurred with abdominal pain, bloating, and reflux, and was maintained for an additional 2 weeks after treatment completion (94946).
• Lactation. It is unclear if oral anise tea is beneficial for increasing human milk production. Details: A moderate-sized clinical study in post-partum adults shows that drinking a tea containing anise 2 grams and black tea 1 gram 3 times daily with meals for 7 days increases the volume of pumped human milk on day 7 by an average of 98 mL and 113 mL, respectively, when compared with a placebo of black tea 3 grams daily and when compared with a control group not assigned to any tea or galactagogues (112863).
• Lice. Topical anise has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in children 6-14 years of age shows that application of a topical spray containing anise oil, coconut oil, and ylang ylang oil three times at 5-day intervals is 92% effective for the treatment of head lice and seems to be comparable in effectiveness to a spray containing permethrin, malathion, piperonyl butoxide, and isododecane (13483).
• Menopausal symptoms. It is unclear if oral anise seed extract is beneficial in patients with menopausal symptoms. Details: A small clinical study in postmenopausal adults shows that taking anise seed extract 330 mg three times daily for 4 weeks reduces the frequency and severity of hot flashes by approximately 75% when compared with placebo (94948).
• Migraine headache. It is unclear if topical anise essential oil is beneficial in patients with migraine headache. Details: A small clinical study in adults with migraine headache shows that applying 2 mL of a cream containing anise essential oil 7% to the temporal and forehead zones at the onset of a migraine reduces the impact of the headache by approximately 10% when compared with a control cream. However, there was no effect of the anise cream on analgesic use or average headache severity when compared with placebo cream. Additionally, due to the strong smell of the anise cream, patient blinding may have been compromised (100166).
• Premenstrual syndrome (PMS). It is unclear if oral anise extract is beneficial in patients with PMS. Details: A small clinical study in female college students with PMS shows that taking anise extract 110 mg three times daily, starting 7 days before menstruation and ending 3 days after, improves concentration, mood, irritability, sleep, food cravings, and other symptoms of PMS, as measured using the Premenstrual Symptoms Screening Tool, when compared with placebo (103875). More evidence is needed to rate anise for these uses.

• Allergic rhinitis (hay fever). Although there has been interest in using oral bromelain for allergic rhinitis, there is insufficient reliable information about the clinical effects of bromelain for this condition.
• Aromatase inhibitor-induced arthralgia. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with aromatase inhibitor-induced arthralgia shows that taking a specific combination product (Opera, Gam Farma), providing bromelain 20 mg, alpha-lipoic acid 240 mg, Boswellia serrata 40 mg, and methylsulfonylmethane 200 mg, daily for 6 months reduces arthralgia symptoms when compared to baseline (109570). The validity of these findings is limited by a lack of placebo control group. Further, it is unclear if these findings are due to bromelain, other ingredients, or the combination.
• Burns. Preliminary clinical research shows that topical bromelain is beneficial for burn debridement. However, it is unclear if topical bromelain is beneficial for scar prevention. Details: Preliminary clinical research and chart reviews show that gels formulated with proteolytic enzymes derived from bromelain (Debridase or NexoBrid, MediWound Ltd.), applied under an occlusive dressing for 4 hours, help debride burns, including chemical and electrical burns, in children and adults (18275,91113,103297,108149). However, only one of these studies compared the bromelain-based enzymatic debridement product to standard of care. In this study, which included surgical excision or non-surgical debridement, bromelain-derived gel decreased the time to complete debridement by 6.5 days, reduced the risk of surgical excision by 65%, and reduced the risk for autografts by 48%. However, in the long-term, there appeared to be no difference in quality of life or scarring between groups (91113).
• Cancer. Although there has been interest in using oral bromelain for cancer, there is insufficient reliable information about the clinical effects of bromelain for this condition.
• Chemotherapy-induced peripheral neuropathy. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in adults with chemotherapy-induced peripheral neuropathy shows that taking a specific product (Opera, Gamfarma s.r.l.) containing bromelain 20 mg, alpha-lipoic acid 240 mg, methylsulfonylmethane (MSM) 200 mg, and boswellia 40 mg daily for 12 weeks reduces overall pain when compared with baseline (96449). The validity of these findings is limited by the lack of a control group. Additionally, it is not clear if benefit is due to alpha-lipoic acid, the other ingredients, or the combination.
• Diabetes. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small observational study in patients with a family history of type 1 diabetes found that taking a specific product (Mucos Pharma) containing bromelain 90 mg. rutin 100 mg, and trypsin 48 mg daily for 24 months is not associated with reduced incidence of type 1 diabetes at 8 years (99472).
• Diabetic foot ulcers. Although there has been interest in using topical bromelain for diabetic foot ulcers, there is insufficient reliable information about the clinical effects of bromelain for this condition.
• Exercise-induced muscle soreness. It is unclear if oral bromelain is beneficial for preventing exercise-induced muscle soreness. Details: One small clinical study shows that taking bromelain 300 mg three times daily, immediately following an intense exercise regimen, does not reduce delayed onset muscle soreness and has no effect on pain, flexibility, or skeletal weakness when compared with either ibuprofen 400 mg three times daily or placebo (10622). However, a small clinical study shows that taking a combination protease tablet containing bromelain 50 mg, trypsin 75 mg, papain 50 mg, amylase 10 mg, lipase 10 mg, lysosome 10 mg, and chymotrypsin 2 mg, four times in one day before downhill running, can improve recovery of contractile muscle function and decrease muscle soreness when compared with placebo (67838). It is unclear if these effects are due to bromelain, other ingredients, or the combination.
• Exercise-induced respiratory infections. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in non-elite male runners shows that taking a combination product (Wobenzym Plus, Mucos Pharma) providing bromelain 540-1080 mg, rutin 600-1200 mg, and trypsin 288-576 mg daily for 3 weeks, starting one week before a marathon, does not reduce the risk of a post-race respiratory tract infection when compared with placebo (96766).
• Kidney stones (nephrolithiasis). It is unclear if oral bromelain is beneficial for kidney stone expulsion. Details: Observational research in patients with 4-10 mm kidney stones found that adding bromelain to tamsulosin is associated with a 12% increased rate of spontaneous stone expulsion when compared to tamsulosin alone (100752).
• Knee pain. It is unclear if oral bromelain is beneficial for knee pain. Details: Preliminary clinical research shows that taking bromelain (Bromelin, Lichtwer Pharma Ltd.) orally for 30 days can reduce mild, acute (duration of less than 3 months) knee pain in otherwise healthy patients when compared to baseline. A daily dose of 400 mg seems to be more effective than 200 mg daily for relieving pain, stiffness, and physical function of the knee, with reductions in symptom scores of 59% and 41%, respectively (11457).
• Lymphedema. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Some clinical research in patients who have undergone a mastectomy shows that taking a specific combination product containing bromelain, rutin, pancreatin, papain, trypsin, and chymotrypsin (Wobenzym N, Mucos Pharma) daily for 7 weeks reduces arm swelling associated with lymphedema when compared with diuretics (24560). Other preliminary clinical research in patients with primary or secondary lymphedema of the upper or lower limbs shows that taking a different combination product containing bromelain 100 mg, rutin 300 mg, and sweet clover 100 mg daily for 6 months decreases pitting, limb volume, pain, and quality of life when compared to baseline (103298). The validity of these results is limited by the lack of a control group. Additionally, it is unclear if these findings are due to bromelain, other ingredients, or the combination.
• Multiple sclerosis (MS). Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A preliminary clinical study in patients with relapsing-remitting MS shows that taking an enzyme combination containing bromelain 90 mg, rutin 100 mg, and trypsin 48 mg per tablet for at least 3 months does not affect the progression of disability, relapse rate, or central nervous system lesions when compared with placebo (99468). The validity of these results is limited by the short duration of treatment.
• Ocular floaters. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A moderate-sized clinical study in patients with spontaneous symptomatic vitreous opacities (ocular floaters) shows that taking oral mixed fruit enzyme capsules containing bromelain 190 mg, papain, and ficin once, twice, or three times daily for 3 months eliminates floaters in 55%, 63%, and 70% of patients, respectively, when compared with an elimination rate of 5% with vitamin C as a control. Additionally, patients with vitreous hemorrhage-induced symptomatic vitreous opacities taking the mixed fruit enzyme capsules 3 times daily for 3 months reduced intraocular blood by 56% and improved visual acuity, but these effects were not found for lower doses and shorter durations when compared with a control (111650). It is unclear if these effects are due to bromelain, other ingredients, or the combination.
• Osteoarthritis. It is unclear if oral bromelain is beneficial for osteoarthritis. Details: A small clinical trial shows that taking bromelain 800 mg daily for 12 weeks as an adjunctive treatment for moderate to severe knee osteoarthritis is no more effective than placebo for improving symptom scores (18274). Other preliminary clinical research shows that taking bromelain 500 mg daily for 4 weeks for mild to moderate knee osteoarthritis is less effective than diclofenac 100 mg daily for improving quality of life, joint pain, and joint function (96216). However, preliminary clinical research shows that oral combination products containing bromelain can reduce pain and improve function in knee osteoarthritis (6252,91104,91106,99467,99477,103299). Bromelain 180 mg has been used in combination with trypsin 144 mg and rutin 200 mg (Phlogenzym, Mucos Pharma GMBH; Wobenzym, Mucos Pharma GmbH) three times daily for 3-12 weeks, with effects comparable to diclofenac, usually taken as 50 mg three times daily for one week, then twice daily thereafter. This product also reduces the need for rescue analgesics by 95% when compared with placebo (6252,91104,99467,99477). Other studies have used a specific combination supplement (AINAT, Laboratoire de Rhumatologie Appliquée) containing Devil's claw 600 mg, turmeric 400 mg, and bromelain 300 mg, taken 2-3 times daily for 2-8 weeks (91106) or a combination of bromelain 250 mg and papain 250 mg (Nature's Life Bromelain & Papain, NutraMarks, Inc.) twice daily, plus aceclofenac 100 mg twice daily for 6 weeks (103299).
• Pain (acute). It is unclear if oral bromelain is beneficial for acute pain. Details: A meta-analysis of 9 small clinical studies in patients experiencing acute pain due to various etiologies shows that taking bromelain slightly improves subjective pain scores and allows patients to open their mouth wider after oral operations when compared with a control (113513).
• Parturition. Although there has been interest in using oral bromelain for shortening the duration of labor, there is insufficient reliable information about the clinical effects of bromelain for this purpose.
• Periodontitis. It is unclear if oral bromelain is beneficial for periodontitis. Details: A very small clinical study in adults with periodontitis shows that taking bromelain 500 mg (Anaheal) twice daily for one week after undergoing pocket elimination surgery reduces bleeding on probing but does not improve gingival index, plaque index, or probing pocket depth when compared with placebo when assessed five weeks after surgery (111691). The validity of these effects is limited by a very small sample size and inadequate statistical power.
• Pityriasis lichenoides chronica (PLC). It is unclear if oral bromelain is beneficial for PLC. Details: A case series suggests that taking bromelain 40 mg orally three times daily for one month, then twice daily for a second month, then once daily for a third month, helps treat episodes of PLC when compared to baseline (18280).
• Postoperative pain. While evidence is mixed, some small clinical studies suggest that oral bromelain reduces postoperative pain aftersome oral surgeries. Details: Meta-analyses and clinical research in a small number of patients undergoing wisdom tooth extraction shows that bromelain modestly reduces pain for up to 8 days when compared with control (91109,91110,100750,100751). Three small clinical trials show that bromelain 160-1500 mg, taken in 3-4 divided doses daily for 4-6 days, reduces dental pain and swelling similarly to taking ketoprofen 100 mg twice daily, diclofenac sodium 25 mg four times daily, or aceclofenac 100 mg twice daily (91109,91110,110546). Additionally, a small clinical study in patients undergoing crown lengthening dental surgeries with either minimal or no bone surgery shows that taking bromelain 200 mg 1 hour before surgery and every 6 hours after surgery reduces pain during the 48-hour postoperative period similarly to ibuprofen 400 mg taken on the same schedule(113898). In contrast, several other small clinical studies show that taking bromelain does not reduce swelling or pain after wisdom tooth extraction when compared with placebo (91107,96214,96215). These studies might have not been sufficiently powered to detect a smaller effect. Meta-analyses also suggest that bromelain does not appear to have a significant effect on postoperative swelling or trismus (100750,100751). However, a more recent study in patients undergoing wisdom tooth extraction shows that taking bromelain 500 mg three times daily for 5 days reduces the severity of postoperative swelling and trismus when compared with aceclofenac, a nonsteroidal anti-inflammatory drug (NSAID) used in some European and Asian countries (110546). Bromelain, in combination with other ingredients, has also been evaluated for reducing pain after rotator cuff tear repair. Clinical research shows that taking a specific supplement (Tenosan, Agave) containing bromelain 50 mg, arginine-L-alpha-ketoglutarate 500 mg, methylsulfonylmethane (MSM) 550 mg, hydrolyzed collagen type I 300 mg, vitamin C 60 mg, and Vinitrox 125 mg daily for 3 months decreases shoulder pain, but does not improve shoulder function, in postoperative patients (19322).
• Postoperative swelling. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small preliminary clinical study in patients undergoing surgery of the jaw shows that taking an enzyme combination of bromelain 180 mg, rutin 200 mg, and trypsin 96 mg twice daily for 5 days in addition to standard treatment reduces soft-tissue thickness (indicating the amount of swelling) at most of the nine assessed facial points when compared to control (99476).
• Rhinosinusitis. It is unclear if oral bromelain is beneficial for rhinosinusitis. Details: Several small clinical trials show that short-term and long-term use of bromelain reduces symptoms of acute and chronic sinusitis, especially nasal mucosal inflammation and edema (18276,18277,18278,18279,91105). The trials used bromelain 40 mg orally (usually the product Ananase) four times daily for six days as an adjunct to antibiotics (18276,18278,18279) or 6 bromelain tablets each containing enzymes of 500 International Pharmaceutical Federation (FIP) units for 12 weeks (91105). Bromelain is usually taken in combination with decongestants, antihistamines, and/or antibiotics. However, the studies have a number of methodological problems, and results are inconsistent. Bromelain has also been evaluated as part of a combination product. A small study in patients over 12 years old with chronic sinusitis shows that taking a combination product containing bromelain 200 mg, Boswellia serrata, black currant, and vitamin D (Flogostop Forte, Humana Italia S.p.A) 1-2 times daily for 15-30 days as an adjunctive therapy to inhaled corticosteroids modulates hyperemia of the mucosa, rhinorrhea, and local inflammation when compared with inhaled corticosteroids alone and baseline (111501). It is unclear if these findings are due to bromelain, other ingredients, or the combination.
• Sprains. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A preliminary clinical study in patients with a sprained ankle shows that taking a specific enzyme combination (Phlogenzym, Mucos Pharma) containing bromelain 90 mg, trypsin 48 mg, and rutin 100 mg, or taking different combinations of the individual enzymes three times daily for 10 days, is no more effective for relieving pain than placebo (99473).
• Tendinopathy. Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in patients with Achilles tendon insertional tendinopathy shows that taking two sachets of a specific supplement (Tenosan, Agave, Prato, Italy) containing a total of bromelain 100 mg, arginine-L-alpha-ketoglutarate 1000 mg, methylsulfonylmethane (MSM) 1100 mg, hydrolyzed collagen type I 600 mg, vitamin C 120 mg, and Vinitrox 25 mg orally for 60 days improves function and pain when compared with placebo (19321).
• Urinary tract infections (UTIs). Oral bromelain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial shows that a combination of bromelain 50 mg and trypsin 1 mg (Kimotab, Mochida Pharmaceutical), taken in a dose of 8 tablets daily for 2 days, does not improve subjective symptoms of UTIs when compared with placebo (18282).
• Venous leg ulcers. Although there has been interest in using topical bromelain for venous leg ulcers, there is insufficient reliable information about the clinical effects of bromelain for this condition.
• Wound healing. It is unclear if enzymatic debridement with bromelain improves the healing of various types of chronic wounds. Details: A meta-analysis of 12 small clinical studies shows that topical bromelain reduces time to complete debridement by around 6 days but has no effect on time to healing when compared with a control (113513). However, the validity of these effects is limited by significant publication bias and a small number of studies per outcome. One small clinical study, included in the analysis above, of patients with chronic wounds related to diabetes, surgery, trauma, or venous insufficiency shows that use of bromelain-based enzymatic debridement (EscharEx, MediWound Ltd), administered as up to ten daily applications of 4 hours each, increases the incidence of complete debridement over the next 6 months to 55% of patients, compared with only 29% of those using the bromelain-free gel. However, there was no difference in changes in wound area, non-viable tissue area, or the incidence or time to complete wound closure (108148). More evidence is needed to rate bromelain for these uses.

• Celiac disease. Although there has been interest in using oral lipase for celiac disease, there is insufficient reliable information about the clinical effects of lipase for this purpose.
• Dyspepsia. It is unclear if oral lipase is beneficial for improving symptoms of postprandial distress syndrome. Details: A small clinical trial shows that taking a specific acid-resistant lipase (Amano Enzyme USA) 280 mg immediately before a high-fat meal does not reduce postprandial bloating and nausea when compared with placebo in individuals with postprandial distress syndrome (101900).
• Inflammatory bowel disease (IBD). Although there has been interest in using oral lipase for IBD, there is insufficient reliable information about the clinical effects of lipase for this purpose.
• Prematurity. It is unclear if adding a specific form of lipase, recombinant human bile salt-stimulated lipase (rhBSSL), to infant formula improves outcomes in premature infants. Some research suggests a potential increased risk for adverse effects. Details: Human breast milk contains rhBSSL, but it is inactivated when breast milk is pasteurized for donation. Clinical research in infants born before 32 weeks' gestation shows that adding rhBSSL as 8700 units per 100 mL formula or pasteurized breast milk, for 4 weeks does not increase growth velocity, body length, or head circumference over the next 12 months when compared with formula or pasteurized breast milk devoid of lipase. However, the infants who were small for gestational age (SGA), which made up approximately 15% of the study population, grew by an additional 1.9 grams/kg daily on average when compared with placebo (101940). More evidence is needed to rate lipase for these uses.

• Cancer. Although there has been interest in using oral papain for cancer, there is insufficient reliable information about the clinical effects of papain for this purpose.
• Dental caries. It is unclear if topical papain gel is beneficial for reducing procedure time or pain in children having caries removed by a dentist. Details: A small clinical study in children 3-9 years of age with dental caries shows that application of a specific papain gel (Brix3000, Brix Medical Science) 3000 U/mg during atraumatic restorative treatment (ART) by a dentist actually increases the time required to remove caries tissue, with no effect on pain, when compared with ART alone (107434).
• Diabetic foot ulcers. Although there has been interest in using topical papain for diabetic foot ulcers, there is insufficient reliable information about the clinical effects of papain for this purpose.
• Exercise-induced muscle soreness. Oral papain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in healthy males shows that taking a combination enzyme tablet containing papain 50 mg, trypsin 75 mg, bromelain 50 mg, amylase 10 mg, lipase 10 mg, lysosome 10 mg, and chymotrypsin 2 mg, four times in one day before downhill running, improves recovery of contractile muscle function and decreases muscle soreness when compared with placebo (67838). It is unclear if these findings are due to papain, other ingredients, or the combination.
• Herpes zoster (shingles). Although there has been interest in using oral papain for shingles, there is insufficient reliable information about the clinical effects of papain for this purpose.
• Insect bite. It is unclear if topical papain is beneficial in individuals with fire ant stings. Details: A small clinical study in individuals with fire ant stings shows that applying gauze soaked with a specific papain-containing meat tenderizer (Adolph's meat tenderizer) to the sting for 20 minutes does not reduce pain or itching when compared with placebo (67845).
• Intestinal parasite infection. Although there has been interest in using oral papain for intestinal parasite infections, there is insufficient reliable information about the clinical effects of papain for this purpose.
• Jellyfish stings. It is unclear if topical papain is beneficial in individuals with jellyfish stings. Details: A small clinical study in individuals with jellyfish stings shows that submerging affected skin into a solution with a papain-containing meat tenderizer (Adolph's meat tenderizer), starting two minutes after a jellyfish sting and continuing for at least 20 minutes, is less effective than hot water alone in decreasing pain caused by the jellyfish sting (67835).
• Ocular floaters. Oral papain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A moderate-sized clinical study in patients with symptomatic ocular floaters shows that taking 1, 2, or 3 capsules daily of an oral mixed fruit enzyme product containing papain 95 mg, ficin 95 mg, and bromelain 190 mg for 3 months leads to 55%, 63%, and 70% of floaters completely disappearing, respectively, when compared to baseline, as well as significant improvements when compared with vitamin C. Additionally, in patients with vitreous hemorrhage-induced symptomatic ocular floaters, taking 3 capsules daily of the same mixed fruit enzyme product for 3 months leads to 56% of floaters completely disappearing and improves visual acuity when compared to baseline, as well as significant improvements when compared with vitamin C (111650). It is unclear if these effects are due to papain, other ingredients, or the combination.
• Pressure ulcers. Although there has been interest in using topical papain for pressure ulcers, there is insufficient reliable information about the clinical effects of papain for this purpose.
• Radiation dermatitis. Oral papain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical study in patients receiving pelvic radiotherapy shows that taking three capsules of a specific combination product (Wobe-Mugos E, Mucos Pharma) containing papain 100 mg, trypsin 40 mg, and chymotrypsin 40 mg per capsule, four times daily, beginning 3 days prior to radiotherapy and continuing until the last day of therapy, does not attenuate skin deterioration when compared with placebo (67834). However, another small, open-label clinical study in patients with uterine carcinoma shows that taking three capsules of the same combination product four times daily, beginning 7 days before radiotherapy and continuing for 9 weeks, reduces skin reactions when compared with control (67831). It is unclear if these findings are due to papain, other ingredients, or the combination.
• Radiation-induced cystitis. Oral papain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with uterine carcinoma receiving radiotherapy shows that taking three capsules of a specific combination product (Wobe-Mugos E, Mucos Pharma) containing papain 100 mg, trypsin 40 mg, and chymotrypsin 40 mg per capsule, four times daily, beginning 7 days before radiotherapy and continuing for 9 weeks, reduces genitourinary symptoms when compared with control (67831).
• Radiation-induced nausea and vomiting. Oral papain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients receiving pelvic radiotherapy shows that taking three capsules of a specific combination product (Wobe-Mugos E, Mucos Pharma), containing papain 100 mg, trypsin 40 mg, and chymotrypsin 40 mg per capsule, four times daily, beginning 3 days prior to radiotherapy and continuing until the last day of therapy, does not reduce radiation-related nausea or vomiting when compared with placebo (67834).
• Tonsillopharyngitis. Oral papain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Two small clinical studies in patients with pharyngitis and/or tonsillitis shows that use of throat lozenges containing papain 2 mg, lysozyme 5 mg, and bacitracin 200 IU daily for 4 days reduces pain and inflammation of the throat and lymph nodes when compared with placebo or disinfectant alone (964,968). It is unclear if these findings are due to papain, other ingredients, or the combination.
• Traumatic oral ulcers. Although there has been interest in using topical papain for traumatic oral ulcers, there is insufficient reliable information about the clinical effects of papain for this purpose.
• Venous leg ulcers. Although there has been interest in using topical papain for venous leg ulcers, there is insufficient reliable information about the clinical effects of papain for this purpose.
• Wound healing. Topical papain has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with purulent wounds shows that applying papain 1% solution plus dimethylsulfoxide (DMSO) followed by phonophoresis, a process by which ultrasound is used to increase topical drug delivery, improves wound healing when compared to baseline (67843). The validity of this finding is limited by the lack of a comparator group. Also, it is unclear if these findings are due to papain, DMSO, or the combination. More evidence is needed to rate papain for these uses.

General ...Orally, bromelain seems to be well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, flatulence, gastric upset, headache.
Topically: Pruritus, urticaria.

Dermatologic ...Topically, bromelain may cause dermal allergic reactions including urticaria, pruritus, and skin swelling (9184). Redness, swelling, burning, pain at the application site, and cellulitis have also been reported rarely (108148,113513). In one case, a fixed drug eruption with pruritis near the groin was reported in a 33-year-old male taking bromelain 50 mg orally daily for 10 days. After discontinuation of bromelain and treatment with topical corticosteroid, the lesion resolved. Upon re-challenge with bromelain, the lesion reappeared in the same area (103300).
In another case report, a 61-year-old male with a history of chronic lower leg ulceration secondary to chronic venous hypertension and recurrent deep vein thrombosis on rivaroxaban presented with a deep-dermal burn on his lower calf. Bromelain-based topical enzymatic debridement agent Nexobrid 2 grams was applied to the burn site. Thirty minutes later, the patient experienced two instances of hemorrhage at the site of debridement. The patient was stabilized and treated with fluids, packed red cells, and tranexamic acid, and then the Nexobrid was removed (111656). Caution should be used in patients with underlying coagulopathies.

Gastrointestinal ...Orally, bromelain may cause gastrointestinal disturbances, including diarrhea, nausea, vomiting, flatulence, and abdominal pain (9184,18274,18282,96216,113513).

Immunologic ...Immunoglobulin E (IgE)-mediated allergic reactions to bromelain may occur (9184).
If inhaled, bromelain may cause sensitization and allergic reactions such as asthma (37199,37215,37233). In case reports of occupational inhalation of bromelain, additional allergic symptoms included difficulty swallowing, throat itching, eye irritation, and rhinitis (37214).

General ...No adverse effects have been reported in adults. However, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Gastrointestinal adverse effects, such as necrotizing enterocolitis, when recombinant human bile salt-stimulated lipase is used in premature infants.

Gastrointestinal ...Orally, when added to the formula or pasteurized breast milk consumed by premature infants, recombinant human bile salt-stimulated lipase (rhBSSL) can cause gastrointestinal adverse effects, including abdominal distension, flatulence, constipation, colic, abdominal pain, gastroenteritis, vomiting, regurgitation, and rectal bleeding (101940). Premature infants receiving rhBSSL also had a slightly higher rate of necrotizing enterocolitis (NEC) when compared with those receiving placebo. After review by a panel of experts, it was determined that the rate of confirmed or suspected NEC in infants consuming rhBSSL was 3.3%, compared with 0.5% in those receiving placebo. Although this rate of NEC is lower than the historical rate of occurrence in premature infants (11%), a possible increased risk for NEC cannot be ruled out (101940).

General ...Orally and topically, papain seems to be well tolerated when used short-term at appropriate doses. Taking high oral doses may be unsafe.
Most Common Adverse Effects:
Orally: Allergic reactions in sensitive individuals.
Topically: Urticaria and pruritus in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Esophageal perforation and severe gastritis with high doses.

Dermatologic ...Topically, papain can cause itching (966). Urticarial reactions and itching have been reported in people occupationally exposed to papain, with papain confirmed as the causative agent by skin prick tests or radioallergosorbent tests (RAST) (95533,95534). In a randomized controlled trial assessing the effects of papain, trypsin, and chymotrypsin on adverse effects from radiotherapy, moderate to severe epitheliolysis was more frequent in the enzyme-treated group than the placebo group (67834). It is unclear if this adverse effect is due to papain, other enzymes, or the combination.

Gastrointestinal ...Orally, papain has been associated with diarrhea. In a randomized controlled trial assessing the effects of papain, trypsin, and chymotrypsin on adverse effects from radiotherapy, moderate to severe diarrhea was more frequent in the enzyme-treated group than the placebo group (67834). However, it is unclear if this adverse effect is due to papain, other enzymes, or the combination. Papain has also been associated with gastric ulcers and esophageal perforation in case reports of phytobezoars treated with papain (67848). In general, large amounts of papain can cause esophageal perforation (6). Ingestion of papaya latex (raw papain) can cause severe gastritis.

Genitourinary ...Orally, papain has been associated with hypernatremia in case reports of phytobezoars treated with papain (67848).

Immunologic ...Orally, papain may cause allergic reactions, including itchy watery eyes, runny nose, sneezing, abdominal cramps, sweating, and diarrhea, in individuals sensitive to papain (6,967). Occupational exposure to airborne papain dust may also cause respiratory allergic reactions (95532,95533,95534,95535,95536).

Pulmonary/Respiratory ...Occupational exposure to airborne papain dust may cause respiratory allergic reactions. Symptoms include rhinitis, sneezing, conjunctivitis, dyspnea, wheezing, cough, and asthma. In most cases, papain is confirmed as the causative agent by skin prick tests, radioallergosorbent tests (RAST), or detection of papain-specific immunoglobulin E (IgE) and IgG (95532,95533,95534,95535,95536).
