• Dyspepsia. Although there has been interest in using oral black pepper for dyspepsia, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Fall prevention. It is unclear if inhaling black pepper oil as aromatherapy is beneficial for fall prevention in older adults. Details: One small clinical study in older adults shows that applying black pepper oil near the right side of the nose as an olfactory stimulant improves stability while the eyes are closed during a one-minute trial when compared with the application of water. The improvement with black pepper oil is comparable to the improvement seen with the application of lavender oil (29160). It is unclear if any benefit persists after inhalation of black pepper oil.
• Fatigue. It is unclear if oral black pepper is beneficial in patients with fatigue. Details: One small clinical trial in adults with below-average energy levels shows that taking black pepper 2 grams as a single dose does not improve sustained attention, motivation to perform cognitive tasks, or feelings of mental energy and mental fatigue when compared with placebo (91731).
• Flatulence. Although there has been interest in using oral black pepper for flatulence, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Headache. Although there has been interest in using oral black pepper for headache, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Insect bite. Topical black pepper has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical trial shows that applying a specific product (Trikatu) containing black pepper, long pepper, and ginger, as well as camphor, eucalyptus oil, and menthol, directly to mosquito bites does not reduce papule size, erythema, edema, or pruritis when compared with a control compound containing the same base ingredients but without the pepper and ginger components (89893).
• Obesity. Although there has been interest in using oral black pepper for obesity, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Pain (chronic). Although there has been interest in using topical black pepper for chronic pain related to various etiologies, including osteoarthritis, postherpetic neuralgia, and peripheral neuropathy, there is insufficient reliable information about the clinical effects of black pepper for these conditions.
• Rhinosinusitis. Although there has been interest in using oral black pepper for rhinosinusitis, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Sexual desire. Although there has been interest in using oral black pepper for increasing sexual desire, there is insufficient reliable information about the clinical effects of black pepper for this purpose.
• Smoking cessation. It is unclear if inhaling black pepper essential oil as aromatherapy is effective for smoking cessation. Details: One small clinical trial in adult male smokers who were deprived from smoking overnight shows that inhaling a vapor from the essential oil of black pepper, as needed over a 3-hour period, reduces cigarette cravings, negative feelings, and anxiety when compared with a placebo vapor (29159). Another small clinical study in patients addicted to dipping, chewing, or smoking tobacco shows that placing a drop of black pepper essential oil on tissue paper and inhaling for 2 minutes at least three times a day for 3 days reduces nicotine cravings when compared to baseline (90502).
• Swallowing dysfunction. It is unclear if inhaling black pepper oil as aromatherapy is beneficial in patients with swallowing dysfunction. Details: One small clinical study in post-stroke residents of nursing homes shows that one minute of olfactory stimulation with black pepper oil before each meal for 30 days decreases swallowing reflex latency by 11 seconds and increases the number of swallowing movements by 3.3 when compared to baseline (29161). A small clinical trial in children with neurological disorders who were on long-term enteral nutrition shows that applying black pepper oil to the nostrils or nasal cavity for one minute improves the amount of oral intake and swallowing movement in 63% of patients. Although oral intake increased, the need for enteral nutrition was not eliminated (29162).
• Vitiligo. It is unclear if topical piperine oil, a constituent of black pepper, is beneficial in patients with vitiligo. Details: A small clinical study in patients with vitiligo shows that applying piperine oil 1% daily in addition to receiving narrowband ultraviolet B (NB-UVB) light therapy every other day for 3 months improves repigmentation more rapidly when compared with using NB-UVB alone (103820). More evidence is needed to rate black pepper for these uses.

• Osteoarthritis. Oral Boswellia serrata extracts, taken alone or in combination with other ingredients, appear to reduce pain and improve function in knee osteoarthritis. However, most clinical studies have been small and methodologically flawed. Details: A meta-analysis of small, randomized, controlled trials in patients with knee osteoarthritis shows that taking Boswellia serrata extract 100-250 mg daily for 1-3 months moderately reduces pain and improves function when compared with placebo (103785). However, the validity of the included studies is limited by incomplete reporting, inadequate blinding, and other methodological issues. Studies included in the meta-analysis tested a specific Boswellia serrata extract (5-Loxin), as well as a specific Boswellia serrata gum resin extract (ApresFLEX, also known as Aflapin). Pain reduction was first noted within 7 days of treatment (17948,17949,21145). More recent evidence on the use of a Boswellia serrata gum resin extract (Aflapin) 100 mg daily for 30 days is consistent with the findings in this meta-analysis (109564). Lower quality studies, not included in the meta-analysis, tested another specific Boswellia serrata gum resin extract (Wokvel, Pharmanza). When taken in a dose of 333 mg three times daily for 2-6 months, this product improves pain and knee function when compared with control. Wokvel seems to have comparable benefit to a solid lipid Boswellia serrata particle product (Wokvida) (12432,21146,103784). Finally, another clinical trial not included in the meta-analysis shows that taking a different Boswellia serrata extract (Boswellin, Sabinsa Corp.) 169 mg twice daily for 4 months also moderately improves pain, stiffness, functional ability, and quality of life when compared with placebo (100699). Several studies also show that taking specific combination products containing Boswellia serrata and other ingredients can improve pain and functionality in patients with osteoarthritis. These products have combined Boswellia serrata 100 mg with ashwagandha 450 mg, turmeric 50 mg, and zinc complex 50 mg (Articulin-F) three times daily for 3 months (19276); Boswellia serrata 100 mg with ginger 33.33 mg, Tinospora cordifolia 73.33 mg, and Indian gooseberry 166.66 mg three times daily for 6 months (89557); a specific Boswellia serrata extract (BosPure, Arjuna Natural Extracts Ltd) 300 mg with turmeric extract (BCM 95, Arjuna Natural Extracts Ltd) 700 mg daily for 12 weeks (89719); boswellic acid 7.2 mg (from Boswellia serrata) with methylsulfonylmethane 5 grams and vitamin C daily for 2 months (96446); and a specific combination product (Tregocel, Max Biocare) providing Boswellia serrata extract 1 gram, curcumin 100 mg, devil's claw tuber 1 gram, celery seed 1 gram, and ginger rhizome 330 mg daily for 36 weeks (106078). However, research in patients with osteoarthritis of the hand suggests that taking a combination of Boswellia serrata extract 250 mg, pine bark extract 100 mg, methylsulfonylmethane 1500 mg, and curcumin 168 mg daily for 12 weeks does not improve pain or functionality (109563).

• Allergic rhinitis (hay fever). Although there is interest in using oral Boswellia serrata for hay fever, there is insufficient reliable information about the clinical effects of Boswellia serrata for this condition.
• Alzheimer disease. It is unclear if oral Boswellia serrata improves cognitive function in patients with Alzheimer disease. Details: A small clinical study in adults with mild to moderate Alzheimer disease shows that taking a specific Boswellia serrata extract (K-Vie, Kondor Pharma) 1200 mg daily for 6 months improves neuropsychiatric symptoms, dementia severity, and some but not all measures of cognitive function when compared with placebo (112807).
• Aromatase inhibitor-induced arthralgia. Oral Boswellia serrata has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with estrogen receptor positive (ER+) breast cancer and aromatase inhibitor-induced arthralgia shows that taking a specific combination product (Opera, Gamfarma Srl) containing Boswellia serrata 40 mg, alpha-lipoic acid 240 mg, methylsulfonylmethane 200 mg, and bromelain 20 mg once daily for 6 months reduces arthralgia intensity when compared to baseline, with around 22% of patients having complete symptom resolution at the end of the study (109570). The validity of these findings is limited by a lack of control group.
• Asthma. It is unclear if oral Boswellia serrata can improve symptoms of asthma. Details: One small preliminary clinical study in patients with asthma suggests that taking a specific Boswellia serrata gum resin (S-compound, Rahul Pharma) 300 mg three times daily for 6 weeks may improve symptoms of asthma, such as forced expiratory volume (FEV), the number of asthma attacks, and dyspnea and rhonchi, in 70% of patients, compared to only 27% of patients in a control group (1708).
• Brain tumor. It is unclear if oral Boswellia serrata improves outcomes in patients with brain tumors. Details: One small clinical study in adults with brain tumors undergoing radiation therapy shows that taking an H15 Boswellia serrata extract 4200 mg in three divided doses daily throughout radiotherapy reduces cerebral edema and tumor volume, but not dexamethasone dosage, when compared with placebo (21149).
• Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS). Rectal Boswellia serrata has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Two small, open-label clinical studies in males with prostatitis-like symptoms or CP/CPPS types IIIa or IIIb shows that rectal administration of a specific suppository containing Boswellia serrata resin extract and propolis polyphenols (MICTALASE) once daily for 20 days or once daily for 15 days per month for 3 months improves pain, urinary symptoms, quality of life, and total symptom scores, as measured by the Chronic Prostatitis Symptom Index (CPSI), when compared to baseline. However, there were no improvements in scores on the International Index of Erectile Dysfunction (IIED), and studies showed mixed findings regarding improvements on the International Prostate Symptoms Score (IPSS) (102091,109566). The validity of these results is limited by the lack of a comparator group.
• Cluster headache. Although there is interest in using oral Boswellia serrata for cluster headache, there is insufficient reliable information about the clinical effects of Boswellia serrata for this condition.
• Coronavirus disease 2019 (COVID-19). Oral Boswellia serrata has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in adults hospitalized with moderate COVID-19 infection in Egypt shows that taking Boswellia serrata extract 300 mg and licorice extract 300 mg twice daily for 14 days, along with conventional therapy, reduces the risk of death, shortens the time to hospital discharge by around 5.5 days, and reduces the rate of mechanical ventilation when compared with placebo. For every five patients treated with this combination product, one additional patient survived. The standard treatments administered in this study included azithromycin, vitamin C, and zinc (108579). Another large clinical study in adults hospitalized with moderate COVID-19 infection in India shows that taking a specific product containing Boswellia serrata, ashwagandha, ginger, and turmeric (Artovid-20, Bioved Pharmaceuticals, Inc) 1,776 mg twice daily after meals for 14 days, starting within 48-96 hours of symptom onset along with conventional therapy, decreases the duration of illness by about 1 day and reduces patient-assessed severity scores of various symptoms (e.g. nasal congestion, sore throat, cough, taste and smell disorders) when compared with placebo. Almost all patients in this study also received steroids, and over 50% received remdesivir. Study results were similar in the subgroup of patients who received remdesivir (109899). However, the validity of this study is limited by use of data only from patients who fully adhered to the study protocol per protocol analysis and exclusion of patients with risks for progression to severe COVID-19, including uncontrolled hypertension, asthma, chronic obstructive pulmonary disease, diabetes, obesity, or immunocompromise.
• Crohn disease. It is unclear if oral Boswellia serrata reduces relapse rates in patients with Crohn disease. Details: One small clinical study in patients with Crohn disease who are in remission shows that taking Boswellia serrata (Boswelan, Pharmasan) 800 mg orally three times daily for one year does not decrease relapse rates or improve quality of life when compared with placebo (17241).
• Diabetes. It is unclear if oral Boswellia serrata improves glycemic control in patients with diabetes. Details: A small clinical study in patients with diabetes who are taking metformin shows that taking powdered Boswellia serrata gum resin 400 mg twice daily after meals for 12 weeks modestly decreases fasting blood glucose, glycated hemoglobin (HbA1c), insulin, and lipid levels when compared with a toasted powder placebo (91378). In contrast, another small clinical study in patients with diabetes shows that taking capsules containing powdered Boswellia serrata gum 250 mg (standardized for 60% boswellic acids) twice daily after meals for 8 weeks does not improve fasting blood glucose, HbA1c, other glycemic parameters, or lipid levels when compared with placebo (105010). However, the interpretation of these findings, specifically the lack of improvement in HbA1c, may be limited by the short duration of the study. A meta-analysis pooling the results of the two trials described above shows that Boswellia serrata reduces HbA1c by about 0.5% and fasting blood glucose by about 24 mg/dL, with no improvement in lipid levels, when compared with placebo (111503).
• Diarrhea. It is unclear if oral Boswellia serrata is beneficial in patients with acute diarrhea. Details: A small clinical study in adults with acute diarrhea shows that taking a specific lecithin-based delivery form of Boswellia serrata extract (Casperome, Indena S.p.A.) 250 mg twice daily for 5 days decreases the time to diarrhea resolution by nearly 1.4 days, reduces stool frequency, and improves symptoms of abdominal pain and nausea when compared with placebo (109568).
• Dysmenorrhea. Oral Boswellia serrata has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in adults with moderately painful dysmenorrhea shows that taking a single dose of a combination product containing Boswellia serrata, turmeric, and sesame (Rhuleave-K, Arjuna Natural Private Ltd.) 1000 mg at the start of menstruation relieves menstrual cramp pain and reduces pain intensity for up to 6 hours when compared with placebo (112806). It is unclear if these effects are due to Boswellia serrata, other ingredients, or the combination.
• Exercise-induced muscle soreness. Oral Boswellia serrata has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in healthy active adults with moderate to severe exercise-induced muscle pain shows that taking a single, 1000-mg dose of Boswellia serrata and turmeric extracts in black sesame oil (Rhuleave-K; Arjuna Natural Private Ltd.) improves pain relief when compared with placebo, with maximal benefits within about 3 hours. The number of people needed to treat to obtain pain relief of at least 50% over a 6-hour period was 1.1 (109277).
• Irritable bowel syndrome (IBS). Small clinical studies suggest that an oral Boswellia serrata extract may improve symptoms of IBS. Details: A small clinical study in patients with mild IBS shows that taking a specific lecithin-based delivery form of Boswellia serrata extract (Casperome, Indena S.p.A.) 250 mg daily for 6 months reduces abdominal pain, cramps, and gas when compared with standard management with hyoscine butylbromide or papaverine hydrochloride plus belladonna extract 10 mg. Patients receiving Casperome required fewer rescue medications and had a 46% lower risk of needing additional medical care, including hospitalization (100713). In a short-term clinical trial of the same Boswellia serrata extract 250 mg daily for 4 weeks, the risk for requiring additional medical care was reduced by 67% when compared with the same standard treatment options above. While IBS symptoms improved over baseline, significant differences between Casperome and standard treatment options were lacking (102089). These studies were funded by the supplement manufacturer, which may limit the reliability of these findings.
• Knee pain. It is unclear if oral Boswellia serrata is beneficial for knee pain. Details: A small clinical study in otherwise healthy adults with knee pain shows that taking Boswellia serrata extract 12.5% tablets twice daily for 8 weeks improves physical function and pain but not stiffness, functional mobility, muscle function, or level of physical activity when compared to baseline (112808).
• Menorrhagia. It is unclear if oral Boswellia serrata is beneficial for menorrhagia. Details: A small clinical study in otherwise healthy adults with menorrhagia shows that taking Boswellia serrata oleoresin powder 300 mg three times daily for 7 days, repeated over 2 menstrual cycles, improves quality of life and modestly reduces the average duration of menstrual bleeding after the second cycle when compared with placebo. All patients were permitted to use ibuprofen 200 mg as needed (105401).
• Microscopic colitis. There is limited evidence on the oral use of Boswellia serrata in patients with collagenous colitis. Details: One small clinical trial shows that taking Boswellia serrata extract 400 mg three times daily for 6 weeks increases the clinical remission rate by 64% when compared with placebo in patients diagnosed with a type of microscopic colitis called collagenous colitis. Clinical remission was defined as having an average of three or fewer soft or solid stools daily during the last week of the study (21152).
• Pain (acute). Oral Boswellia serrata has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with acute musculoskeletal pain shows that taking a specific combination product containing Boswellia serrata and turmeric extracts in black sesame oil (Rhuleave-K; Arjuna Natural Private Ltd.) 1000 mg daily for 7 days is as effective as acetaminophen 1000 mg daily for pain relief, onset of pain relief, and onset of maximal pain relief (109287). This study is limited by its lack of blinding and placebo control. Additionally, the dose of acetaminophen used in this study is below the standard recommended daily dose.
• Rheumatoid arthritis (RA). Oral Boswellia serrata has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One clinical trial in patients with RA shows that taking two capsules of a specific product containing Boswellia serrata 100 mg, ashwagandha 450 mg, turmeric 50 mg, and zinc complex 50 mg (Articulin-F) three times daily for 3 months improves pain, morning stiffness, grip strength, and disability scores when compared with placebo (21154). However, another clinical trial in patients with RA shows that taking two tablets of a standardized extract formulation (RA-1) containing Boswellia serrata, ashwagandha, ginger, and turmeric three times daily for 16 weeks does not improve most symptoms when compared with placebo (21155).It is unclear if these findings are due to Boswellia serrata, other ingredients, or the combination.
• Rhinosinusitis. Oral Boswellia serrata has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients over 12 years of age with chronic sinusitis shows that taking a combination product containing Boswellia serrata, black currant, bromelain, and vitamin D (Flogostop Forte, Humana Italia) with inhaled corticosteroids daily for 30 days reduces rhinorrhea, hyperemia of mucosa, and local inflammation when compared with inhaled corticosteroids alone (111501). It is unclear if these findings are due to Boswellia serrata, other ingredients, or the combination. Pharyngitis. Although there is interest in using oral Boswellia serrata for pharyngitis, there is insufficient reliable information about the clinical effects of Boswellia serrata for this condition.
• Stroke. It is unclear if oral boswellic acids improve neurological function after stroke. Details: One small clinical study in adults with recent ischemic stroke who are taking aspirin and clopidogrel shows that taking boswellic acids 800 mg three times daily for 30 days improves neurological function, as measured using the National Institutes of Health Stroke Scale, when compared with placebo (102092).
• Traumatic brain injury (TBI). It is unclear if oral Boswellia serrata is effective for reducing disability, or improving cognitive function or memory in adults recovering from TBIs. Details: A small clinical crossover study in adults admitted to the hospital for diffuse axonal injury shows that taking powdered Boswellia serrata oleogum resin 360 mg three times daily for 6 weeks does not improve disability when compared with placebo (91379). However, another small clinical study in patients suffering from a TBI 3 months to 3 years earlier shows that taking a specific Boswellia serrata extract (K-Vie, Kondor Pharma) 400 mg three times daily for 3 months improves performance on cognitive function tests, including those assessing processing speed, memory, and overall cognitive function, when compared with placebo (109567). A moderate-size clinical study in adults with memory dysfunction due to a recent mild traumatic brain injury in Iran shows that taking a specific product containing Boswellia serrata 360 mg and ginger 36 mg (Memoral, Goldarou) three times daily for 1 month modestly improves practitioner-assessed memory function scores when compared with placebo (110132). However, it is unclear if this effect is due to Boswellia serrata, ginger, or the combination.
• Ulcerative colitis. Small clinical studies suggest that oral Boswellia serrata extracts may improve symptoms of ulcerative colitis. Details: Two very small clinical trials in patients with active ulcerative colitis suggest that taking Boswellia serrata gum resin 300-350 mg three times daily for 6 weeks improves symptoms and disease markers comparably to taking sulfasalazine 1 gram three times daily (1709,12438). These findings are limited because the sample size may have been inadequate to assess differences between groups. In patients with ulcerative colitis in remission, one observational study has found that taking a specific lecithin-based delivery form of Boswellia serrata extract (Casperome, Indena S.p.A.) 250 mg daily for 4 weeks is associated with a reduction in abdominal pain, cramps, and malaise, a decrease in the need for additional medications, and a 58% lower risk for requiring additional medical care when compared with no treatment. Additionally, weekly episodes of bloody diarrhea, bowel movements, and watery stools were reduced when compared with baseline (102090).
• Urinary incontinence. Oral Boswellia serrata has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in postmenopausal adults with urinary incontinence shows that taking a 3 tablets of a multi-ingredient herbal product containing Boswellia serrata 100 mg and five other herbs twice daily for 4 weeks reduces urinary incontinence frequency and leakage amount when compared with placebo, with improvements similar to those reported with solifenacin as standard therapy (111502). It is unclear if these effects are due to Boswellia serrata, other ingredients, or the combination.
• Urinary tract infections (UTIs). Oral Boswellia serrata has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small observational study in patients with an uncomplicated UTI has found that taking two tablets of a specific combination product (Acidif plus) containing Boswellia serrata gummy dry extract 100 mg, L-methionine 400 mg, and hibiscus 100 mg daily for 7 days is associated with reduced UTI symptoms and reduced bacteriuria when compared with taking an unreported dose of fosfomycin for 2 days (103783). The validity of this study is limited by its observational nature and a lack of information on the severity of UTI at baseline. Also, it is unclear if these effects are due to Boswellia serrata, other ingredients, or the combination. More evidence is needed to rate Boswellia serrata for these uses.

CARBAMAZEPINE (Tegretol) Interaction Rating = Minor Be watchful with this combination. Severity = Mild •  Occurrence = Possible •  Level of Evidence = B Theoretically, black pepper might increase blood levels of carbamazepine, potentially increasing the effects and side effects of carbamazepine.  Details One clinical study in patients taking carbamazepine 300 mg or 500 mg twice daily shows that taking a single 20 mg dose of purified piperine, a constituent of black pepper, increases carbamazepine levels. Piperine may increase carbamazepine absorption by increasing blood flow to the GI tract, increasing the surface area of the small intestine, or inhibiting cytochrome P450 3A4 (CYP3A4) in the gut wall. Absorption was significantly increased by 7-10 mcg/mL/hour. The time to eliminate carbamazepine was also increased by 4-8 hours. Although carbamazepine levels were increased, this did not appear to increase side effects (16833). In vitro research also shows that piperine can increase carbamazepine levels by 11% in a time-dependent manner (103819).
