Exercise-induced muscle soreness. Oral catechu has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in healthy runners shows that taking a specific combination product (AmLexin, Unigen) containing extracts of catechu 67 mg and white mulberry 133 mg twice daily for 8 weeks during training and for 1 week after a half-marathon reduces muscle pain and stiffness on the first and third days post-race when compared with placebo (103270).
Osteoarthritis. Oral catechu has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a specific combination product (Limbrel, Primus Pharmaceuticals) containing flavocoxid, a combination of flavonoid extracts from catechu and Baikal skullcap, 500 mg once or twice daily for up to 12 weeks reduces symptoms of osteoarthritis of the knee when compared to baseline. These studies found no significant difference between this combination product and naproxen 440 mg once daily or naproxen 500 mg twice daily for reducing symptoms (17030,18012,92776). However, in 2017, the US Food and Drug Administration (FDA) formally requested the recall of all non-expired lots of this product due to the risk for liver and lung injury (106042). See the Adverse Effects section for more information. More evidence is needed to rate catechu for these uses.

Constipation. Oral Corydalis yanhusuo has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with functional constipation shows that taking a specific supplement (Motilitone, Dong-A ST) containing 30 mg of Corydalis yanhusuo and Pharbitis seed extracts three times daily before meals for 24 days improves colonic transit time, stool frequency, and symptoms of abdominal discomfort and pain when compared to baseline. At the start of the study, 63% of patients reported less than one stool per week. At the end of the study, 78% of patients were experiencing one or more stools per week, with 11% of patients reporting more than three stools per week (97159). The validity of these findings is limited by a lack of placebo control group.
Depression. Although there has been interest in using oral Corydalis yanhusuo for depression, there is insufficient reliable information about the clinical effects of Corydalis yanhusuo for this purpose.
Dysmenorrhea. Although there has been interest in using oral Corydalis yanhusuo for dysmenorrhea, there is insufficient reliable information about the clinical effects of Corydalis yanhusuo for this purpose.
Dyspepsia. Oral Corydalis yanhusuo has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One clinical trial in patients with functional dyspepsia shows that taking a specific supplement (Motilitone, Dong-A ST) containing 30 mg of Corydalis yanhusuo and Pharbitis seed extracts three times daily before meals for 4 weeks improves dyspepsia to a similar degree as pantoprazole 40 mg (97158).
Gastroesophageal reflux disease (GERD). Oral Corydalis yanhusuo has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with GERD shows that taking a specific supplement (Motilitone, Dong-A ST) containing 30 mg of Corydalis yanhusuo and Pharbitis seed extracts three times daily before meals for 4 weeks does not improve symptoms of dyspepsia or quality of life when compared with placebo (97160).
Headache. Although there has been interest in using oral Corydalis yanhusuo for headache, there is insufficient reliable information about the clinical effects of Corydalis yanhusuo for this purpose.
Helicobacter pylori. Although there has been interest in using oral Corydalis yanhusuo for Helicobacter pylori, there is insufficient reliable information about the clinical effects of Corydalis yanhusuo for this purpose. More evidence is needed to rate Corydalis yanhusuo for these uses.

There is insufficient reliable information available about the effectiveness of dragon's blood.

FRANKINCENSE

Acne. Although there is interest in using topical frankincense for acne, there is insufficient reliable information about the clinical effects of frankincense for this purpose.
Aging skin. Small clinical studies suggest that topical cream containing frankincense extracts may improve symptoms of aging skin. Details: Small studies in females with photodamaged skin suggests that applying a cream containing boswellic acids 0.5%, from Boswellia serrata, to the face reduces fine surface lines, tactile roughness, and photo-aging scores when compared to baseline. However, no differences were found for other outcomes, such as skin pigmentation and course wrinkling (21156,21157). The validity of these findings is limited by the lack of a comparator group.
Back pain. Topical frankincense has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in adults with chronic low back pain shows that two 15-minute sessions of lumbar massage weekly with 5 mL of frankincense 2% and myrrh 2% essential oils for 3 weeks reduces measures of pain and disability when compared with placebo (111504). It is unclear if these effects are due to frankincense oil, myrrh oil, or the combination.
Cancer-related fatigue. It is unclear if topical frankincense oil improves fatigue in patients with cancer. Details: A small clinical study in outpatient adults with cancer-related fatigue shows that applying frankincense 5% in jojoba oil to the soles of both feet for 2 days before, during, and 2 days after chemotherapy does not improve patient-reported fatigue scores when compared with jojoba oil alone (110144).
Coronavirus disease 2019 (COVID-19). Inhaled frankincense has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study of females aged 14-49 with ongoing fatigue for more than 5 months after COVID-19 infection shows that inhaling a specific essential oil product containing essential oils of frankincense, clove, orange, and thyme (Longevity, Young Living Essential Oils) for 15 minutes twice daily for 14 days improves self-reported fatigue and quality of life scores when compared with placebo (110143). However, the validity of these findings is limited by lack of adequate blinding.
Osteoarthritis. It is unclear if topical frankincense is beneficial in patients with osteoarthritis. Details: A small clinical study in adults with knee osteoarthritis shows that applying an oil-based frankincense extract to the affected knee 3 times daily for 4 weeks reduces pain and improves measures of flexibility, stiffness, and function when compared with placebo (111505).
Rheumatoid arthritis (RA). Topical frankincense has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in Chinese patients with RA shows that applying a cream containing frankincense, thunder god vine, natrii sulfas, chuanxiong root, and myrrh twice daily to affected joints for 4 weeks reduces pain and swollen, tender joints when compared with a control cream (105436).
Radiation dermatitis. It is unclear if topical frankincense cream reduces the severity of radiation dermatitis. Details: Preliminary clinical research in patients with breast cancer shows that topical application of cream containing frankincense as Boswellia serrata extract 2% (Bosexil, Indena SpA) twice daily for approximately 5 weeks throughout radiation therapy reduces the number of patients who experience intense erythema and reduces the need for cortisone cream when compared with applying a placebo cream (91380). The validity of these findings is limited by reporting bias. This study was also funded by the cream manufacturer, which may further limit the reliability of these findings.
Vaginal candidiasis. It is unclear if intravaginal frankincense is beneficial in patients with vaginal candidiasis. Details: A small clinical study in adults with vulvovaginal candidiasis shows that intravaginal administration of frankincense 1 gram tablets daily for 21 days reduces dyspareunia, dysuria, vaginal discharge, vulvar pruritis and swelling, curdy discharge, and erythema when compared to baseline. Compared to miconazole vaginal suppositories administered for 7 days, vaginal frankincense is similarly effective in all outcomes mentioned previously but shows greater improvement in vulval pruritis and vaginal discharge (111506). The validity of these findings is limited by the small sample size, differing dosage forms, and variance in treatment length.
Wound healing. Although there is interest in using topical frankincense for wound healing, there is insufficient reliable information about the clinical effects of frankincense for this purpose. More evidence is needed to rate frankincense for these uses.

MYRRH

LIKELY INEFFECTIVE

Schistosomiasis. Most research suggests that oral myrrh extract is not effective for treating schistosomiasis. Details: Although one manufacturer-sponsored study shows that taking a specific myrrh extract (Mirazid, Pharco Pharmaceuticals) 600 mg once daily for 6 days cures schistosomiasis in about 90% of patients, multiple clinical studies show that taking this myrrh extract does not treat schistosomiasis in children or adults. In one study, only about 9% of adults and children treated with this myrrh extract at a dose of 600 mg every 3 weeks for 2 doses were cured compared to about 76% of patients treated with praziquantel (95541). A similar lack of benefit was shown in another clinical trial in which children were given a higher dose of 300 mg daily for 3 days or 600 mg daily for 6 days (95542,95545). A systematic review of the available literature concludes that praziquantel continues to be the treatment of choice for schistosomiasis, and that myrrh appears ineffective for parasitological cure (95544).

Back pain. It is unclear if oral myrrh is beneficial in patients with back pain, and topical myrrh has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in adults with chronic low back pain shows that two 15-minute sessions of lumbar massage weekly with 5 mL of myrrh 2% and frankincense 2% essential oils for 3 weeks reduces measures of pain and disability when compared with placebo (111504). An observational study in adults with chronic lower back pain and sciatica suggests that taking a combination of myrrh 200 mg, palmitoylethanolamide 600 mg, and alpha-lipoic acid 800 mg daily for 30 days, along with periradicular infiltrations of oxygen-ozone, is associated with resolution of pain in 17% more patients when compared with periradicular steroid infiltrations at 60 days (111308). However, it is unclear if the effects in these studies are due to myrrh, other ingredients, or the combinations. Additionally, observational research in adults with chronic low back pain of varying intensity has found that taking a specific myrrh extract (MyrliMax, Sundyota Numandis Pharmaceuticals) 100 mg twice daily for 20 days is associated with reductions in pain and the need for rescue analgesics when compared to baseline (111112). The validity of these findings is limited by the lack of a control group.
Cancer. Although there has been interest in using oral myrrh for cancer, there is insufficient reliable information about the clinical effects of myrrh for this purpose.
Canker sores. Although there has been interest in using topical myrrh for canker sores, there is insufficient reliable information about the clinical effects of myrrh for this purpose.
Common cold. Although there has been interest in using oral myrrh for the common cold, there is insufficient reliable information about the clinical effects of myrrh for this purpose.
Cough. Although there has been interest in using oral myrrh for cough, there is insufficient reliable information about the clinical effects of myrrh for this purpose.
Crohn disease. Oral myrrh has only been evaluated in combination with other ingredients, its effect when used alone is unclear. Details: Observational research over a period of 24-28 days in a small group of patients with active inflammatory bowel disease (50% ulcerative colitis and 50% Crohn disease) has found that taking a specific combination product containing myrrh 100 mg, coffee charcoal 50 mg, and chamomile extract 70 mg per tablet (MYRRHINIL-INTEST, Repha GmbH) results in symptom resolution in 16-26 days. The probability of being free of symptoms did not differ between patients using other treatments, the myrrh combination product alone, or a combination of the myrrh product with other treatments. Overall efficacy was rated as good to very good by patients and physicians (104593). The validity of these findings is limited by the observational nature of the study. Also, it is unclear if these findings are due to myrrh, other ingredients, or the combination.
Dental peri-implantitis. It is unclear if rinsing with myrrh mouthwash solution is effective for the prevention of dental peri-implantitis. Details: A small clinical study in adults undergoing dental implant placement shows that rinsing with myrrh 1% mouthwash solution twice daily for 2 weeks leads to similar rates of postoperative bleeding, pain, redness, and swelling when compared with chlorhexidine 0.12% mouthwash (111114).
Diarrhea. Oral myrrh has only been evaluated in combination with other ingredients, its effect when used alone is unclear. Details: Observational research over a period of 7-14 days in a group of patients with active diarrhea related to an acute inflammatory disorder has found that taking a specific combination product containing myrrh 100 mg, coffee charcoal 50 mg, and chamomile extract 70 mg per tablet (MYRRHINIL-INTEST, Repha GmbH), alone or in combination with other therapies, improves overall symptoms of diarrhea. The median time to symptom resolution was 4 days. The probability of symptom resolution with use of the myrrh combination product was similar to that observed when other treatments were used. Overall efficacy was rated as good to very good by patients and physicians (104593). The validity of these findings is limited by the observational nature of the study. Also, it is unclear if these findings are due to myrrh, other ingredients, or the combination.
Fasciolosis. It is unclear if oral myrrh extract is beneficial in patients with fasciolosis. Details: A small clinical study in adults and children with fasciolosis shows that taking a specific myrrh extract (Mirazid, Pharco Pharmaceuticals) 600 mg daily for 6 days leads to a cure rate of about 94% at 3 months. However, the lack of standardized stool sample evaluation and absence of a control group limit the validity of this finding (95543). Furthermore, another small study in adults and children with fasciolosis shows that taking this same product, 600 mg daily for 6 days, leads to a 0% cure rate at both 1 and 2 months (95545).
Gingivitis. Although there has been interest in using topical myrrh for gingivitis, there is insufficient reliable information about the clinical effects of myrrh for this purpose.
Herniated disc. Oral myrrh has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small observational study in adults with acute lumbosacral radiculopathy secondary to lumbar disc herniation suggests that taking a combination supplement containing myrrh 100 mg, alpha-lipoic acid 404 mg, and palmitoylethanolamide (PEA) 306 mg (Tiobec Dol, Uriach Italy Srl) twice daily for 4 weeks, along with steroids and as needed opioids, is associated with reduced pain and disability and improved physical but not mental health as it pertains to quality of life when compared with steroids and as needed opioids alone (111711). However, it is unclear if these effects are due to alpha-lipoic acid, other ingredients, or the combination.
Intestinal parasite infection. It is unclear if oral myrrh extract is beneficial in children with intestinal parasite infections. Details: A small clinical study in immunocompetent children shows that taking a specific myrrh extract (Mirazid, Pharco Pharmaceuticals) 10 mg/kg daily in combination with paromomycin 500 mg four times daily for 2 weeks improves symptoms such as abdominal pain, diarrhea, nausea, and vomiting when compared with paromomycin or myrrh extract alone. However, no differences in oocyst elimination were observed across groups (95546).
Irritable bowel syndrome (IBS). Oral myrrh has only been evaluated in combination with other ingredients, its effect when used alone is unclear. Details: Observational research over a period of 24-28 days in a group of patients with IBS has found that taking a specific combination product containing myrrh 100 mg, coffee charcoal 50 mg, and chamomile extract 70 mg per tablet (MYRRHINIL-INTEST, Repha GmbH), alone or in combination with other therapies, improves overall symptoms of diarrhea. The probability of being free of symptoms did not differ between patients using other treatments or when the myrrh combination product was used in combination with other treatments. Overall efficacy was rated as good to very good by patients and physicians (104593). The validity of these findings is limited by the observational nature of the study. Also, it is unclear if these findings are due to myrrh, other ingredients, or the combination.
Miscarriage. It is unclear if oral myrrh is beneficial in patients with incomplete miscarriage. Details: A small clinical study in adults with incomplete miscarriage (incomplete abortion) shows that taking myrrh 500 mg three times a day for 2 weeks increases the proportion of patients with successful complete abortion, defined as no retained products of conception, to 83%, compared to only 54% of those taking placebo (104840).
Muscle cramps. Although there has been interest in using oral myrrh for muscle cramps, there is insufficient reliable information about the clinical effects of myrrh for this purpose.
Oral mucositis. Although there has been interest in using topical myrrh for oral mucositis, there is insufficient reliable information about the clinical effects of myrrh for this purpose.
Pain (acute). It is unclear if oral myrrh extract is beneficial in patients with acute pain. Details: A small clinical study shows that taking a specific, standardized myrrh extract (MyrLiq, Biosfered S.r.l.) 200-400 mg daily for 20 days can improve various types of acute pain, including headache, fever-associated pain, joint or muscle pain, lower back pain, and menstrual cramps, when compared with placebo (98224).
Pain (chronic). It is unclear if oral myrrh extract is beneficial in patients with chronic pain. Details: A small clinical study shows that taking a specific, standardized myrrh extract (MyrLiq, Biosfered S.r.l.) 200-400 mg daily for 20 days can improve various types of chronic pain, including joint or muscle pain and lower back pain, when compared with placebo (98224).
Peptic ulcers. Although there has been interest in using oral myrrh for peptic ulcers, there is insufficient reliable information about the clinical effects of myrrh for this purpose.
Sciatica. Oral myrrh has only been evaluated in combination with other ingredients, its effect when used alone is unclear. Details: Observational research in patients with sciatic pain due to herniated discs has found that taking a combination of myrrh extract 200 mg, alpha-lipoic acid 800 mg, and palmitoylethanolamide 600 mg daily for 20 days along with 3 sessions of oxygen-ozone therapy over 30 days is associated with slight improvements in pain when compared with oxygen-ozone therapy alone (111113). The validity of these findings is limited by the observational nature of the study. Additionally, it is unclear if these findings are due to myrrh, other ingredients, or the combination.
Tooth extraction. It is unclear if rinsing with myrrh extract solution is beneficial in patients undergoing tooth extraction. Details: A small clinical study in healthy, non-smoking adults shows that using a mouthwash containing myrrh extract 0.5% twice daily for 7 days following simple tooth extraction decreases the socket size in 90% of patients compared with 40% in the control group. Swelling and tenderness also decreased when compared with control (105846).
Trichomoniasis. It is unclear if oral myrrh extract is beneficial in patients with trichomoniasis. Details: A small clinical study in patients with resistant Trichomonas vaginalis shows that taking a specific myrrh extract (Mirazid, Pharco Pharmaceuticals) 600 mg daily for 6-8 days cures infections in most patients. In this small study, 85% (11/13) of patients who did not respond to combination therapy with metronidazole and tinidazole were cured after receiving this myrrh extract (93652). A lack of control group limits the validity of these findings.
Ulcerative colitis. Oral myrrh has only been evaluated in combination with other ingredients, its effect when used alone is unclear. Details: A small clinical study in patients with ulcerative colitis shows that taking a specific combination product containing myrrh 100 mg, chamomile extract 70 mg, and coffee charcoal 50 mg per tablet (MYRRHINIL-INTEST, Repha GmbH), four tablets three times daily for 12 months, is non-inferior to mesalamine therapy for maintaining remission (93653). In addition, observational research over a period of 24-28 days in a small group of patients with active inflammatory bowel disease (50% ulcerative colitis and 50% Crohn disease) has found that taking this same product results in symptom resolution in 16-26 days. The probability of being free of symptoms did not differ between patients using other treatments, the myrrh combination product alone, or the myrrh combination product with other treatments. Overall efficacy was rated as good to very good by physicians (104593). It is unclear if these findings are due to myrrh, other ingredients, or the combination.
Urinary tract infections (UTIs). Oral myrrh has only been evaluated in combination with other ingredients, its effect when used alone is unclear. Details: A small clinical study in patients with at least 2 recurrent UTIs in the past 6 months or more than 3 UTIs in the past year shows that taking a combination of myrrh, hibiscus, and vegetable proteases (Aviur Retard ) for 6 months might reduce the risk of UTI recurrence. A UTI episode was not reported by 49% of females over the 6-month period, with an additional 35% reporting fewer than 2 UTIs (101115). The validity of these findings is limited by the lack of comparator group. Additionally, it unclear if this benefit is due to myrrh, other ingredients, or the combination.
Wound healing. It is unclear if topical myrrh extract is beneficial for wound healing. Details: Two small clinical studies in patients requiring episiotomy during childbirth shows that using myrrh 1:5 tincture 10 mL or myrrh extract 20 mL, diluted in 5 L of water as a sitz bath, twice daily for 7 days, modestly improves ecchymosis, discharge, and wound healing scores when compared with either placebo, frankincense extract 20 mL, or betadine 10% solution 20 mL (104838,104839). It is unclear if these modest effects are clinically relevant. More evidence is needed to rate myrrh for these uses.

POSSIBLY EFFECTIVE

Cognitive function. In middle-aged individuals, but not young adults, oral Panax ginseng seems to improve abstract thinking, attention, arithmetic skills, and reaction time. Any benefit to memory seems to be dependent on the inclusion of ginkgo. Details: Some clinical evidence shows that taking Panax ginseng orally can improve abstract thinking, attention, mental arithmetic skills, and reaction times in healthy, middle-aged people; however, Panax ginseng does not seem to improve these outcomes in young adults (2064,23596,23599,23608,23609,54374). While Panax ginseng alone does not seem to improve memory (2064), there is some evidence that a combination of Panax ginseng (G115) and ginkgo leaf (GK501) extract 80-320 mg daily for 12 weeks can improve memory in otherwise healthy people or people with neurasthenia 38-66 years of age (8591,9759,87984,88046). In clinical trials, various doses have been used. These include a specific Panax ginseng extract (G115, Pharmaton SA, Lugano) 200-400 mg once daily or in two divided doses for up to 12 weeks, or 200-960 mg administered as a single dose (8591,23596,23599,23608,23609,54374,88046). Another extract (Gerimax Ginseng Extract; Dansk Droge A/S Ishoj) 400 mg daily for 8 weeks has also been used (2064).
Erectile dysfunction (ED). Oral Panax ginseng seems to improve sexual function in people with ED. Details: Taking Panax ginseng orally for 8 weeks seems to improve sexual function in adults with ED (8813,23637,23638,89747). Doses used in clinical research have included extract from the juice and pulp of 4 year-old Panax ginseng berry 700 mg twice daily (89747), tissue-cultured mountain ginseng extract 1000 mg twice daily (23638), and Korean red ginseng, a type of Panax ginseng, 1000-2700 mg daily (8813,112840). Panax ginseng has also been studied in adults with symptoms of ED that are associated with an enlarged prostate. A small clinical study in adult males with moderate lower urinary tract symptoms shows that taking a specific extract of Korean red ginseng (RXGIN, Jung Kwan Jang), a type of Panax ginseng, 1000 mg daily for 12 weeks improves symptoms of sexual dysfunction including erectile function, sexual desire, orgasmic function, and intercourse satisfaction when compared with placebo. However, there was no improvement reported in overall satisfaction. Most symptoms of ED except sexual desire had not significantly improved by 6 weeks, suggesting that longer durations of at least 12 weeks may be needed for Panax ginseng to significantly improve ED symptoms (112840). Additionally, Panax ginseng has been evaluated in combination with other ingredients. A moderate-sized, open-label clinical study in adults with mild-to-moderate ED shows that taking a specific combination supplement (Icarifil, Anvest Health S.p.A) containing Panax ginseng 150 mg, L-carnitine, L-citrulline, tribulus, and other ingredients daily for 3 months improves patient-reported erectile function when compared to baseline. Additionally, taking the supplement with tadalafil improves some, but not all, patient-reported assessments of erectile function when compared with taking tadalafil alone (114989). It is unclear if this effect is due to Panax ginseng, other ingredients, or the combination. Additionally, the interpretation of these results is limited by poor methodology, including the use of per-protocol analysis and lack of a placebo group.
Influenza. Oral Panax ginseng seems to modestly reduce the risk of developing influenza. However, it might not reduce the severity or duration of symptoms. Details: Some preliminary clinical research shows that taking a specific Panax ginseng extract (G115) 200 mg daily, beginning 4 weeks prior to influenza vaccination and continuing for 8 weeks thereafter, can decrease the relative risk of getting the flu or common cold by 65% when compared with placebo (589). Also, clinical research in healthy adults shows that taking Panax ginseng extract 1 gram three times daily for 12 weeks reduces the relative risk of developing an acute influenza infection by 45% when compared with placebo. However, taking Panax ginseng does not seem to affect symptom duration or severity (89746).
Multiple sclerosis-related fatigue. Oral Panax ginseng seems to reduce fatigue and improve quality of life in patients with multiple sclerosis. Details: Clinical research shows that taking Panax ginseng 250 mg twice daily for 3 months improves symptoms of fatigue and quality of life when compared with placebo in female patients with relapsing-remitting multiple sclerosis (RRMS). Females taking Panax ginseng experienced a 75% reduction in fatigue, compared with no change in the placebo group; quality of life was increased by 19.9 points in the Panax ginseng group, compared with only 4.2 in the placebo group (89745).
Sexual arousal. Oral Panax ginseng, alone or in combination with other ingredients, seems to improve sexual arousal in postmenopausal adults or females with sexual dysfunction. Details: Taking Korean red ginseng, a specific form of Panax ginseng, 3 grams daily for 8 weeks seems to improve sexual arousal and satisfaction when compared with placebo in postmenopausal adults (23630). Also, other preliminary clinical research shows that taking a specific combination product (ArginMax for Women, Daily Wellness Company) containing ginkgo leaf extract, Panax ginseng root extract, damiana leaf extract, L-arginine, multivitamins, and minerals for 4 weeks can improve sexual satisfaction when compared with placebo in females who are self-reported to have sexual dysfunction (23635,46933). It is unclear if this effect is due to Panax ginseng, other ingredients, or the combination.

POSSIBLY INEFFECTIVE

Athletic performance. Most research shows that oral Panax ginseng does not improve athletic performance. Details: Taking Panax ginseng 0.4 to 3 grams daily orally for up to 8 weeks, or as a single dose 200 mg one hour prior to exercise, does not improve aerobic exercise capacity (1427,4230,4231,23646,23647,89737,114981). Higher doses of Panax ginseng also do not seem to improve athletic performance. A small study in young athletes shows that taking Panax ginseng 100 mg/kg (about 5-7 grams, standardized to 10% ginsenosides) daily in three divided doses for 8 days does not improve squat exercise performance, although it might modestly improve perceived exertion, when compared with placebo (103045). Similarly, a small clinical study in adult male recreational athletes shows that taking Panax ginseng extract 500 mg daily for 14 days does not improve 10-kilometer running times when compared with placebo (114981).

Aging. Although there has been interest in using oral Panax ginseng for aging, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Anthracycline cardiotoxicity. It is unclear if oral Panax ginseng protects against anthracycline cardiotoxicity. Details: A very small clinical study in adults with non-metastatic HER-2 negative breast cancer being treated with anthracycline-based chemotherapy in Iran shows that taking Panax ginseng rhizome powder 1000 mg daily starting on the first day of doxorubicin administration until one week after completion of the eighth doxorubicin cycle improves left ventricular ejection fraction (LVEF) by 1% when compared with placebo, which was associated with a 7% reduction in LVEF. Treatment with Panax ginseng also reduces the incidence of chemotherapy-related cardiac dysfunction when compared with placebo, an effect that endured over a 6-month follow up period. However, Panax ginseng did not improve the cardiac biomarker high-sensitive cardiac troponin I or transthoracic echocardiographic measurements of left atrium diameter, left ventricular end-systolic diameter, or left ventricular end-diastolic diameter when compared with placebo (112817).
Attention deficit-hyperactivity disorder (ADHD). Oral Panax ginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small low-quality study in children with ADHD aged 6-12 years shows that taking Panax ginseng extract 3 mg with omega-3 fatty acids 500 mg daily for 12 weeks improves overall symptoms, reduces errors of commission, and improves reaction time when compared with baseline (103049). The validity of this study was limited by the lack of a comparator group. Also, it is unclear if these changes are due to Panax ginseng, omega-3 fatty acids, or the combination.
Age-related cognitive decline. It is unclear if oral Panax ginseng is beneficial in age-related cognitive decline. Details: Clinical research in patients over 50 years of age with memory impairments shows that taking standardized ginseng extract (G115) in combination with vitamins, minerals, and dimethylaminoethanol bitartrate may improve memory when compared to baseline (23600). The validity of this finding is limited by the lack of a comparator group. Also, it is unclear if these changes are due to Panax ginseng, other ingredients, or the combination.
Allergic rhinitis (hay fever). It is unclear if oral Panax ginseng is beneficial in allergic rhinitis. Details: A small clinical study in adults with allergic rhinitis shows that taking Panax ginseng (Korean Ginseng Corporation) 3 mg/kg daily for 4 weeks improves rhinorrhea, nasal itch, and eye itch when compared to baseline (103047). The validity of this study is limited because it did not report statistical comparisons between the treatment and control groups.
Alzheimer disease. Some preliminary clinical studies suggest that oral Panax ginseng might improve cognitive performance in patients with this condition. Details: Clinical research shows that taking Panax ginseng root 4.5 to 9 grams daily for 12 weeks can improve cognitive performance in patients with Alzheimer disease when compared with control (23611,23612). The validity of this finding is limited by the lack of patient and caregiver blinding.
Androgenic alopecia. Topical Panax ginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with androgenic alopecia shows that applying 1 mL of a topical combination product (Hirsuit hair tonic, Dermcor Pharmaceutical) containing Panax ginseng extract, biochanin A (from red clover), acetyl tetrapeptide-3, Salvia officinalis oil, and other ingredients, twice daily for 24 weeks, is similarly effective to minoxidil 3% solution for increasing hair count and mass (105672). It is unclear if the benefit is due to Panax ginseng, other ingredients, or the combination.
Anxiety. Although there has been interest in using oral Panax ginseng for anxiety, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Aplastic anemia. Although there has been interest in using oral Panax ginseng for aplastic anemia, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Asthma. Although there has been interest in using oral Panax ginseng for asthma, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Benign prostatic hyperplasia (BPH). It is unclear if oral Panax ginseng is beneficial for treating lower urinary tract symptoms. Details: A small clinical study in adults with moderate lower urinary tract symptoms shows that taking a specific extract of Korean red ginseng (RXGIN, Jung Kwan Jang), a type of Panax ginseng, 1000 mg daily for 12 weeks reduces serum prostate-specific antigen (PSA) and improves most prostate symptoms including residual urine sensation, frequency, intermittency, urgency, weak stream, straining, and nocturia after 6 and 12 weeks when compared with placebo. However, there was no improvement in maximum urinary flow rate or post-void residual volume when compared with placebo (112840).
Breast cancer. It is unclear if oral Panax ginseng is beneficial in breast cancer. Details: Observational research in Chinese patients with breast cancer suggests that regular use of ginseng, including either Panax ginseng or American ginseng, is associated with higher quality of life scores and a lower risk of overall mortality, breast cancer-related mortality, and breast cancer recurrence when compared with patients who do not take ginseng (14466). However, ginseng users were also significantly more likely to have been treated with tamoxifen. Another small clinical study in adults with non-metastatic breast cancer undergoing anthracycline-based chemotherapy in Iran shows that taking Panax ginseng 1 gram daily starting on the first day of chemotherapy until 1 week after completion of the final cycle at 7 or 10 weeks improves social, emotional, and functional measures of health-related quality of life but does not improve physical well-being when compared with placebo (112823).
Bronchitis. It is unclear if oral Panax ginseng is beneficial in bronchitis. Details: One small clinical study shows that taking a specific Panax ginseng extract (G115) 100 mg twice daily for 9 days might be beneficial when used adjunctively for treating acute exacerbations of chronic bronchitis. Panax ginseng, combined with antibiotic therapy, might reduce bronchial bacterial counts more than antibiotic therapy alone (8814).
Cancer. It is unclear if oral Panax ginseng is beneficial in preventing cancer. However, it might increase quality of life in some cancer patients. Details: Observational research has found that taking ginseng orally might decrease the incidence of cancer, specifically breast, stomach, lung, liver, ovarian, and skin cancer (2063,3122). But evidence from large-scale clinical research shows that taking Panax ginseng 1 gram once weekly for 3 years does not reduce the risk of cancer development (23622). However, some clinical research suggests that Panax ginseng may slow cancer progression or improve quality of life in patients already diagnosed with cancer. One clinical study shows that taking sun ginseng, a form of Panax ginseng that has been heat treated, 3000 mg daily orally for 12 weeks can improve quality of life for cancer patients (23643). Evidence from a case series suggests that giving Panax ginseng (also called Cultivated Wild Ginseng Pharmacopuncture) 20 mL daily by intravenous infusion for up to 13 cycles lasting 2-4 weeks each may attenuate the progression of advanced non-small cell lung cancer in some patients (23619,23620).
Cancer-related fatigue. It is unclear if oral Panax ginseng is beneficial in cancer-related fatigue. Details: Preliminary clinical research shows that taking Panax ginseng 400 mg twice daily for 4 weeks reduces fatigue in 63% of adults with cancer-related fatigue when compared to baseline. Panax ginseng also reduces pain and improves appetite and overall quality of life when compared to baseline. The lack of a control group limits the validity of these findings (96217). Another clinical study in patients with colorectal cancer receiving the mFOLFOX-6 chemotherapy regimen shows that taking Panax ginseng 2000 mg daily for 16 weeks improves fatigue as measured on the brief fatigue inventory (BFI) when compared with placebo. However, when evaluated on the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue scale, no benefit was seen (103048).
Chronic fatigue syndrome (CFS). It is unclear if oral Panax ginseng is beneficial in patients with severe CFS. Details: A nonblinded, observational study in patients with severe CFS, most of whom also have fibromyalgia, shows that taking Panax ginseng daily for one month improves patient reports of energy, overall wellbeing, mental clarity, sleep, pain, and stamina when compared with baseline. Patients took Panax ginseng either as capsules (Terry Naturally HRG80 Red Ginseng Energy capsules; EuroPharma, Inc) 200-400 mg daily or chewable tablets (Terry Naturally HRG80 Red Ginseng Energy chewable tablets; EuroPharma, Inc) 100-200 mg daily. There were no dose- or formulation-dependent differences between groups (107746). The validity of these findings is limited by the lack of randomization and placebo-control; additionally, the majority (89%) of patients included in this study were female.
Chronic kidney disease (CKD). It is unclear if oral Panax ginseng prevents CKD. Details: A cross-sectional study in Korea suggests that supplemental Panax ginseng or American ginseng use is associated with a higher prevalence of CKD when compared with no supplemental ginseng use. However, no association was found when adjusting the results for potential confounders (112810). The applicability of these results is limited by a lack of subgroup analysis on the type of supplemental ginseng.
Cognitive impairment. It is unclear if oral Panax ginseng is beneficial for the prevention or treatment of cognitive impairment. Most research has evaluated Panax ginseng in combination with other ingredients. Details: Preliminary clinical research in elderly patients with mild cognitive impairment shows that taking a specific combination product (Memo, Pharco Pharmaceuticals), which contains natural lyophilized royal jelly 750 mg, standardized ginkgo leaf extract 120 mg, and standardized Panax ginseng root extract 150 mg, orally for 4 weeks improves memory when compared with placebo (89712). It is unclear if these benefits are due to Panax ginseng, other ingredients, or the combination. A moderate-sized clinical study in older adults with subjective memory impairment shows that taking a specific Panax ginseng sprout extract (ThinkGIN, BTC Corporation) 450 mg daily for 12 weeks improves performance on some verbal and visual memory tests and cognitive function as measured with MoCA-Korean version when compared with placebo (114983).
Common cold. It is unclear if oral Panax ginseng is beneficial in preventing the common cold. Details: Preliminary clinical research shows that taking a specific Panax ginseng extract (G115) 200 mg daily orally beginning 4 weeks prior to influenza vaccination and continuing for 8 weeks thereafter can decrease the relative risk of getting the flu or common cold by 65% when compared with placebo (589).
Congestive heart failure (CHF). It is unclear if oral Panax ginseng is beneficial in CHF. Details: A small clinical study in adults with CHF shows that Panax ginseng 2 grams daily, with or without digoxin 0.25 mg once daily for 15 days, seems to improve heart function according to New York Heart Association (NYHA) classification when compared to baseline. Ginseng might also improve hemodynamics and may work synergistically with digoxin (4243). The validity of these findings is limited by the lack of a comparator group.
Constipation. It is unclear if oral fermented Panax ginseng is beneficial for constipation. Details: An observational study in healthy postmenopausal adults aged 50 years and older in Korea suggests that taking fermented red ginseng 20 mL before meals daily for 3 weeks normalizes stool consistency and increases the frequency of bowel movements when compared to baseline (112837). The validity of these effects is limited by the observational study design, lack of a comparator group, and insufficient blinding.
Chronic obstructive pulmonary disease (COPD). Oral Panax ginseng has primarily been evaluated in combination with other ingredients for improving symptoms of COPD; its effect when used alone is unclear. Taking Panax ginseng doesn't seem to prevent exacerbations. Details: A meta-analysis of clinical trials in patients with stable COPD shows that taking Panax ginseng, usually in combination with other ingredients as part of TCM formulations, significantly improves pulmonary function tests and quality of life when compared with placebo after 3-6 months of treatment. These formulations improve COPD symptoms by approximately 53% when compared with placebo. However, they only modestly improve forced expiratory volume in one second (FEV1) (17736). In contrast, Panax ginseng might not reduce the risk of COPD exacerbations. A clinical study in patients with moderate to very severe COPD shows that taking Panax ginseng 200 mg does not reduce the rate of acute COPD exacerbations over 12 months (103044).
Depression. It is unclear if Panax ginseng is beneficial in depression. Details: In adults with treatment-resistant major depressive disorder, a small clinical study shows that taking Panax ginseng 2 grams daily in addition to current antidepressant medications for 6 weeks produces remission in 39% of patients and decreases scores on the Montgomery-Asberg Depression Rating Scale by a mean of 44% when compared with baseline (104954). The reliability of these findings is limited by the lack of a control group, randomization, blinding, and an intention-to-treat analysis, as well as a high drop-out rate.
Diabetes. Research on the use of oral Panax ginseng for improving glycemic control in patients with diabetes is inconclusive and conflicting. Details: A meta-analysis of 6 small clinical trials in patients with type 2 diabetes using Panax ginseng for 4-24 weeks and 3 small trials using American or unidentified ginseng for 4-8 weeks, shows that taking these ingredients modestly reduces fasting blood glucose, but does not affect glycated hemoglobin (HbA1c) or insulin levels, when compared with control (105689). This analysis is limited by publication bias, as well as the heterogeneity and imprecision of the included trials. Another meta-analysis of 5 clinical studies in healthy adults and adults with a variety of metabolic disorders including diabetes and prediabetes shows that taking Panax ginseng 200 mg up to 8 grams daily for 4 to 24 weeks does not improve fasting blood glucose, 2-hour postprandial blood glucose, HbA1c, or insulin levels when compared with placebo. However, Panax ginseng might improve glucose AUC in these individuals. Subgroup analysis further suggests that the beneficial effect of Panax ginseng on glucose AUC is greater in adults with diabetes than those with prediabetes (112838). Individual small studies have shown modest glycemic benefit with fermented Panax ginseng 2.7 grams daily for 4 weeks or non-fermented Panax ginseng 6 grams daily for 8-12 weeks (23627,89740), and other studies have shown no benefit with Korean red ginseng extract or Korean black ginseng 2-8 grams daily for 4-6 weeks (17734,112839). It is unclear if the effects of Panax ginseng may be dose- or product-dependent. Panax ginseng has also shown some glycemic benefit when used in combination with other ingredients. Panax ginseng extract 750 mg (standardized to 30% ginsenosides) has been used in combination with American ginseng extract 1500 mg (standardized to 10% ginsenosides), viscous fiber 10 grams, and ground white chia seeds 60 grams daily for 24 weeks (105673). It is unclear if this benefit is due to Panax ginseng, other ingredients, or the combination.
Diabetic neuropathy. It is unclear if oral Panax ginseng is beneficial in diabetic neuropathy. Details: A small clinical study in patients with diabetic neuropathy shows that taking Panax ginseng extract powder 1 gram daily for 24 weeks seems to improve sensory perception of electric currents, a marker for severity of diabetic neuropathy, when compared with baseline (103051). The validity of this study was limited by the lack of statistical comparison between treatment and placebo groups.
Exercise-induced muscle damage. Although there has been interest in using oral Panax ginseng for exercise-induced muscle damage, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Fatigue. Most clinical research shows that oral Panax ginseng can reduce fatigue in adults with idiopathic chronic fatigue. However, not all research agrees. Details: Some clinical research in patients with idiopathic chronic fatigue or self-reported fatigue shows that taking Panax ginseng improves self-reported fatigue when compared with baseline or placebo (89743,23623,106665). A small clinical study in patients with idiopathic chronic fatigue shows that taking an ethanolic extract of Panax ginseng 1 gram twice daily for 4 weeks reduces self-reported fatigue by 66% and mental fatigue by 50% when compared with placebo (89743). Another clinical study in adults with chronic fatigue also shows that taking a specific combination product containing Panax ginseng (G115) 80 mg, vitamins, and minerals daily for 7 weeks alleviates fatigue symptoms in 20% more patients when compared with placebo (23623). However, not all research has been positive. A small clinical study in middle-aged patients with idiopathic chronic fatigue shows that taking Panax ginseng, steamed and aged for six years, 3 grams daily for 6 weeks is no different than placebo for reducing fatigue (103052). Notably, this clinical trial had a robust placebo effect.
Fibromyalgia. It is unclear if oral Panax ginseng is beneficial for fibromyalgia. Details: Clinical research shows that taking Panax ginseng root extract 100 mg daily orally for 12 weeks does not improve pain, fatigue, sleep quality, anxiety, tender point count, or quality of life when compared with placebo in patients with fibromyalgia (89744). A nonblinded, observational study in patients with fibromyalgia, most of whom also have severe chronic fatigue syndrome (CFS), shows that taking Panax ginseng daily for one month improves patient reports of energy, overall wellbeing, mental clarity, sleep, pain, and stamina when compared with baseline. Patients took Panax ginseng, either as a capsule (Terry Naturally HRG80 Red Ginseng Energy capsules; EuroPharma, Inc) 200-400 mg daily, or chewable tablet (Terry Naturally HRG80 Red Ginseng Energy chewable tablets; EuroPharma, Inc) 100-200 mg daily. There were no dose- or formulation-dependent differences between groups (107746). The validity of these findings is limited by the lack of randomization and placebo-control; additionally, the majority (89%) of patients included in this study were female.
Gallbladder disease. It is unclear if oral Panax ginseng is beneficial for gallbladder disease. Details: Clinical research shows that taking Panax ginseng 7.5 grams as an adjuvant to the bile acids chenodeoxycholic acid (CDCA) 500 mg daily plus ursodeoxycholic acid (UDCA) 500 mg daily, divided into three doses daily for 24 weeks, does not decrease the total volume of gallstones or increase gallstone dissolution when compared to use of bile acids alone (89748).
Gastritis. Although there has been interest in using oral Panax ginseng for gastritis, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Glaucoma. It is unclear if oral Panax ginseng is beneficial for glaucoma. Details: A clinical crossover study in patients with glaucoma shows that taking oral Panax ginseng 1 gram three times daily for 4 weeks improves dry eye severity, daytime visual function, and eye pain when compared with placebo. In a sub-group of patients with early or moderate glaucoma, nighttime visual function was also improved (107744). The validity of this study is limited due to short duration of treatment.
Halitosis. It is unclear if oral Panax ginseng is beneficial for halitosis. Details: Preliminary clinical research shows that taking Korean red ginseng, a type of Panax ginseng, 2.7 grams daily for 10 weeks helps reduce bad breath when compared with baseline, particularly in patients with bad breath caused by Helicobacter pylori (H. pylori) infection (23624). The validity of this finding is limited by the lack of a comparator group.
Hangover. It is unclear if oral Panax ginseng is beneficial for hangover. Details: One small clinical study shows that drinking 100 mL of a drink containing Panax ginseng extract 0.321 mg/mL within 5 minutes of drinking 100 mL blended Scotch whiskey with 40% alcohol and eating a piece of cheese may reduce hangover symptoms by approximately 66% when compared with placebo in healthy males. Levels of alcohol in the blood also appear to be reduced (89742).
Hearing loss. It is unclear if oral Panax ginseng is beneficial for hearing loss. Details: Preliminary clinical research in male textile workers exposed to continuous noise shows that taking Korean red ginseng, a type of Panax ginseng, 200 mg daily for 14 days reduces temporary hearing loss caused by noises at frequencies of 4, 6, or 16 kHz when compared with control. However, Panax ginseng may be slightly less effective than N-acetyl cysteine at preventing temporary hearing loss caused by noise at 4 kHz frequency (89739).
HIV/AIDS. It is unclear if oral Panax ginseng is beneficial for this condition. Details: Preliminary clinical research in adults with HIV shows that taking Korean red ginseng, a particular form of Panax ginseng, along with highly active antiretroviral therapy (HAART) modestly increases CD4 count, but does not affect viral load, when compared with HAART alone (23625).
Hyperlipidemia. It is unclear if oral Panax ginseng is beneficial for hyperlipidemia. Details: A meta-analysis of clinical studies in healthy adults and adults with a variety of metabolic disorders shows that taking Panax ginseng 200 mg to 8 grams daily for 4 to 24 weeks reduces total cholesterol by 7 mg/dL and low-density lipoprotein (LDL) cholesterol by 9 mg/dL but does not reduce triglycerides or increase high-density lipoprotein (HDL) cholesterol when compared with placebo (112838). However, a meta-analysis of up to 28 clinical studies in healthy adults and adults with a variety of metabolic disorders shows that taking Panax ginseng 300 mg to 6 grams daily for 3 to 32 weeks does not reduce total or LDL cholesterol or triglycerides or increase HDL cholesterol when compared with placebo (114985).
Hypertension. It is unclear if oral Panax ginseng is beneficial for hypertension. Details: A meta-analysis of clinical studies in healthy adults and adults with a variety of metabolic disorders shows that taking Panax ginseng 200 mg to 8 grams daily for 4 to 24 weeks does not reduce systolic (SBP) or diastolic (DBP) blood pressure when compared with placebo. However, subgroup analysis suggests that Panax ginseng might modestly reduce SBP in people with prehypertension, hypertension, or metabolic syndrome (112838). Smaller individual studies of various forms of Panax ginseng have been evaluated in patients with mild to severe hypertension with conflicting results. Some preliminary clinical research in patients with essential hypertension shows that taking Panax ginseng 4.5 grams daily in three divided doses, alone or with a beta-blocker or calcium channel blocker for 8 weeks, moderately decreases 24-hour SBP (23632). However, in patients with prehypertension or mild hypertension, taking protopanaxatriol-enriched Panax ginseng (Ginseol K-g1) 100 mg or 300 mg daily for 8 weeks does not reduce seated SBP or DBP when compared with placebo (89741). Panax ginseng has also been evaluated in combination with American ginseng. Clinical studies in patients with hypertension with or without type 2 diabetes show that taking Panax ginseng 0.75 grams and American ginseng 1.5-2.25 grams enriched to contain 30% total ginsenosides daily for 12 weeks reduces central SBP by about 5 mmHg and 24-hour SBP by about 4 mmHg, but does not impact DBP, when compared with placebo or a control of wheat-bran (103046,107745). Patients receiving this combination also have greater reductions in daytime SBP, glycated hemoglobin, total cholesterol levels, and triglyceride levels when compared with control (107745). It is unclear if these effects are due to Panax ginseng, American ginseng, or the combination; additionally, it is unclear if enrichment with ginsenosides alters clinical effects.
Impaired glucose tolerance (prediabetes). It is unclear if oral Panax ginseng is beneficial for impaired glucose tolerance. Details: In overweight adults with prediabetes, a small clinical study shows that taking hydrolyzed Panax ginseng extract, 320 mg three times daily before meals for 6 months, does not improve fasting blood glucose levels. However, compliance in this study was only 49% (104953). Additionally, a large, cross-over, clinical study in patients with prediabetes initiating a lifestyle intervention shows that taking a Chinese herbal medicine preparation containing Panax ginseng providing ginseng berry saponins 50 mg three times daily for 4 weeks improves 2-hour post-prandial glucose, but not fasting blood glucose, when compared with placebo (114980). Panax ginseng has also been studied in combination with other ingredients. One clinical study shows that taking a combination of Korean red ginseng, a type of Panax ginseng, and cheonggukjang, a type of fermented soybean paste, 20 grams daily for 8 weeks can decrease fasting blood glucose levels by 17% in patients with prediabetes (23640). Also, taking fermented Panax ginseng 2.7 grams daily for 4 weeks reduces 2-hour postprandial glucose by about 17% and increases 2-hour postprandial insulin levels by about 44% when compared to baseline; when compared with placebo, these changes are significant (89740). It is unclear if these effects are due to Panax ginseng, other ingredients, or the combinations.
Inflammatory bowel disease (IBD). Although there has been interest in using oral Panax ginseng for Crohn disease and ulcerative colitis, there is insufficient reliable information about the clinical effects of Panax ginseng for these conditions.
Insomnia. Although there has been interest in using oral Panax ginseng for insomnia, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Liver disease. Although there has been interest in using oral Panax ginseng for liver diseases, there is insufficient reliable information about the clinical effects of Panax ginseng for these conditions.
Male infertility. It is unclear if oral Panax ginseng is beneficial for male infertility. Details: Chronic prostatitis due to Chlamydia trachomatis infection is associated with reduced male fertility due to decreased sperm concentration and motility. Preliminary clinical research in adults with this condition shows that taking 25 mL of a specific product containing L-arginine 1660 mg, L-carnitine 150 mg, acetyl-L-carnitine 50 mg, and Panax ginseng 200 mg (Fertimev) along with prulifloxacin 600 mg daily for 6 months improves sperm concentration and sperm motility when compared to treatment with prulifloxacin alone (59006). It is unclear if this effect is due to Panax ginseng, other ingredients, or the combination.
Menopausal symptoms. Research on oral Panax ginseng for menopausal symptoms has yielded conflicting results. Details: One clinical study in postmenopausal adults shows that taking Panax ginseng extract (G115) 200 mg daily orally for 16 weeks does not improve psychological well-being or reduce vasomotor symptoms such as hot flashes when compared with placebo (10981). However, several smaller clinical studies in postmenopausal adults demonstrate beneficial effects with higher doses of Panax ginseng. One study shows that taking Panax ginseng 1 gram (containing 30 mg ginsenosides) three times daily for 12 weeks reduces hot flashes and other symptoms, as measured by the Kupperman index and the Menopause Rating Scale (MRS), when compared with placebo (89749). Another study shows that taking an extract of Korean red ginseng, a specific form of Panax ginseng, 500 mg 4 times daily for 8 weeks improves fatigue severity scores by 21%, compared with 3% in those receiving placebo (106666). In premenopausal adults with menopausal symptoms following surgery for gynecologic cancer, taking Panax ginseng 1 gram three times daily for 12 weeks reduces the total symptom score on the MRS when compared with baseline. However, there was also a robust response in the placebo group, with no significant difference in symptom reduction between groups (104596). Panax ginseng has also been evaluated for improving genitourinary syndrome and cognition after menopause. A small clinical trial in postmenopausal adults with genitourinary syndrome shows that taking a specific Panax ginseng supplement (Ruginseng, Ghaem Daru Pharmaceutical) 500 mg twice daily for 4 weeks does not affect vaginal maturation index or pH, but seems to improve patient-rated symptoms such as vaginal itching and burning, when compared with a lactose placebo (105670). This study was funded by the supplement manufacturer. In another clinical study, taking a specific combination product (Gincosan) containing Panax ginseng 200 mg and ginkgo 120 mg daily for 6-12 weeks does not improve cognition, memory, mood, anxiety, or sleep when compared with placebo (87767).
Metabolic syndrome. It is unclear if oral Panax ginseng is beneficial for metabolic syndrome. Details: A meta-analysis of 23 clinical studies in healthy adults, menopausal adults, and adults with a variety of metabolic disorders shows that taking Panax ginseng 200 mg to 8 grams daily for 4 to 24 weeks reduces glucose area under the plasma concentration-time curve (AUC), total cholesterol, and high-density lipoprotein cholesterol, but does not improve other measures of blood glucose, insulin resistance, blood pressure, lipids, or anthropometric measures when compared with placebo (112838). Additionally, a small clinical study in adults with metabolic syndrome shows that taking Korean red ginseng, a specific form of Panax ginseng, 6 grams daily for 8 weeks modestly reduces systolic blood pressure from baseline, but not when compared with placebo. Additionally, Panax ginseng has no effect on anthropometric measurements, biochemical markers, or other vital signs when compared with placebo (106667).
Nausea and vomiting. Although there has been interest in using oral Panax ginseng for nausea and vomiting, there is insufficient reliable information about the clinical effects of Panax ginseng for these conditions.
Neuropathic pain. Although there has been interest in using oral Panax ginseng for neuropathic pain, there is insufficient reliable information about the clinical effects of Panax ginseng for this condition.
Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral Panax ginseng is beneficial for NAFLD. Details: A small clinical study in adults with NAFLD shows that taking Panax ginseng 2 grams (containing ginsenosides 4.5 mg/gram) daily for 30 days modestly reduces fatigue and plasma levels of alanine aminotransferase (ALT) and gamma-glutamyl transferase (GGT) when compared with placebo. All patients were also given milk thistle dried extract 450 mg (Legalon, Bukwang Pharmaceutical) daily and asked to exercise daily for at least 30 minutes (105671).
Oral cancer. It is unclear if topical Panax ginseng is beneficial for oral health in patients with oral cancer. Details: A small clinical study in patients with oral cancer and poor oral hygiene shows that rinsing with a specific herbal mouthwash (Dr. Dental care liquid, Jangin Pharm Co., Ltd.) containing Panax ginseng 8 mL for 1 minute twice daily for 14 days reduces oral bacterial load and improves oral hygiene and gingival indices when compared with chlorhexidine or saline rinses (114987).
Osteoarthritis. It is unclear if oral Panax ginseng is beneficial for osteoarthritis of the hand. Details: A small clinical study in postmenopausal adults with degenerative osteoarthritis of the hand shows that taking oral Korean red ginseng, a type of Panax ginseng, 1 gram three times daily for 12 weeks improves pain scores at rest, during daily activity, and at work or sport, and also improves disabilities of the arm, shoulder, and hand (DASH) score when compared with placebo (107747). The validity of this trial is limited due to the lack of objective outcome measures.
Pneumonia. Injectable Panax ginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Oral Panax ginseng has not been evaluated for this use. Details: A meta-analysis of 20 small, low-quality randomized and non-randomized studies in older Chinese adults with severe pneumonia shows that administering an injection containing Panax ginseng extract 0.8 mg/mL and aconite extract 0.1 mg/mL in addition to standard treatment leads to improvement in symptoms such as fever, cough, and chest tightness in 77% of patients as compared with 61% of those who received standard treatment alone. This combination injection may also modestly reduce disease severity and the risk of mortality when compared with standard treatment alone. However, these outcomes were not evaluated in all studies, and dosing regimens were heterogenous (110472). Additionally, it is unclear whether these effects are due to Panax ginseng, aconite, or the combination.
Premature ejaculation. Oral Panax ginseng has primarily been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Applying a multi-ingredient cream preparation containing Panax ginseng, angelica root, Cistanches deserticola, Zanthoxyl species, torlidis seed, clove flower, asiasari root, cinnamon bark, and toad venom (SS Cream) to the glans penis one hour prior to intercourse and washing off immediately before intercourse seems to improve ejaculatory latency in adults with premature ejaculation when compared with placebo (2537). It is unclear if this effect is due to Panax ginseng, other ingredients, or the combination.
Quality of life. It is unclear if oral Panax ginseng is beneficial for quality of life. Details: While some research suggests that Panax ginseng might improve self-rated quality of life (6254,23644), other studies show no benefit (8601,10314). In studies showing benefit for quality of life, doses have included one capsule daily of a specific Panax ginseng extract (Pharmaton Capsules, Pharmaton Natural Health Products) for 12 weeks (6254) and Panax ginseng extract (G115) 40 mg twice daily for 12 weeks (23644).
Rheumatoid arthritis (RA). It is unclear if oral Panax ginseng is beneficial for improving symptoms of RA. Details: A moderate-sized clinical study in patients with RA, Sjogren syndrome, or both shows that taking Panax ginseng 2000 mg daily for 3 months does not improve fatigue scores when compared with placebo (114984).
Sjogren syndrome. It is unclear if oral Panax ginseng is beneficial in patients with Sjogren syndrome. Details: A moderate-sized clinical study in patients with RA, Sjogren syndrome, or both shows that taking Panax ginseng 2000 mg daily for 3 months does not improve fatigue scores when compared with placebo (114984).
Stress. It is unclear if oral Panax ginseng is beneficial for stress. Details: A small clinical study in healthy patients with occupational stress shows that taking a specific Panax ginseng root preparation (HRG80) high in ginsenosides daily for 14 days modestly reduces perceived stress and improves attention and memory when compared with placebo. However, taking a standard Panax ginseng preparation with a lower quantity of ginsenosides was no better than placebo (103050). However, a moderate-sized clinical study in adult males shows that taking Panax ginseng 2000 mg daily for 8 weeks does not improve self-reported stress response when compared with placebo (114988).
Stroke. It is unclear if oral Panax ginseng prevents stroke. Details: A small clinical study in adults with severe atherosclerosis in major intracranial arteries or extracranial carotid arteries at high risk for ischemic stroke shows that taking an extract of Korean red ginseng, a type of Panax ginseng, 1000 mg twice daily for 12 months does not prevent transient ischemic attack or ischemic stroke and does not improve neurological disability, cerebral blood flow, or the incidence of new ischemic brain lesions when compared with placebo (112835).
Traumatic brain injury (TBI). It is unclear if oral Panax ginseng is beneficial for asthenic syndrome due to TBI. Details: A small study in adults with asthenic syndrome secondary to mild combat TBI shows that taking Panax ginseng improves autonomic nervous system functioning and asthenic symptoms when compared to baseline (112834). The validity of these effects is limited by a lack of a comparator group.
Vascular dementia. Oral Panax ginseng has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients aged 60 years or older with vascular dementia shows that taking a supplement containing extracts of Panax ginseng, ginkgo, and saffron three times daily for 16 weeks modestly improves some cognitive function scores, caregiver assessed activities of daily living, and patient-reported quality of life when compared with placebo. However, these effects were not maintained after patients stopped taking the supplement (111336). Additionally, it is unclear if these effects are due to Panax ginseng, other ingredients, or the combination.
Wrinkled skin. It is unclear if oral Panax ginseng is beneficial for wrinkled skin. Details: Preliminary clinical research shows that taking 3 grams of a combination of Korean red ginseng root with Torilus fructus and Corni fructus daily for 24 weeks may reduce wrinkles when compared with placebo. However, it does not seem to affect skin elasticity, moisture, thickness, or color (23645). It is unclear if this benefit is due to Panax ginseng, other ingredients, or the combination. More evidence is needed to rate Panax ginseng for these uses.

Safety view details

Below is general information about the safety of the known ingredients contained in the product Resinall K. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.

CATECHU

LIKELY SAFE ...when used orally in amounts commonly found in foods. Catechu has Generally Recognized As Safe (GRAS) status for use in foods in the US (4912). There is insufficient reliable information available about the safety of catechu when used orally in medicinal amounts. A specific product (Limbrel, Primus Pharmaceuticals) containing flavocoxid, a mixture of flavonoid extracts from catechu and Baikal skullcap, has been associated with an increased risk for liver and lung injury. In 2017, the US Food and Drug Administration (FDA) formally requested the recall of all non-expired lots of this product (106042). It is unclear if these effects were due to catechu, Baikal skullcap, or the combination. There is insufficient reliable information available about the safety of catechu when used topically.

Details

In one case, a patient who was previously stable on warfarin had a significant decline in international normalized ratio (INR) following consumption of an aqueous extract of myrrh (14425).

ANTICOAGULANT/ANTIPLATELET DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Unlikely • Level of Evidence = B

Although Panax ginseng has shown antiplatelet effects in the laboratory, it is unlikely to increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.

Details

In vitro evidence suggests that ginsenoside constituents in Panax ginseng might decrease platelet aggregation (1522,11891). However, research in humans suggests that ginseng does not affect platelet aggregation (11890). Animal research indicates low oral bioavailability of Rb1 and rapid elimination of Rg1, which might explain the discrepancy between in vitro and human research (11153). Until more is known, use with caution in patients concurrently taking anticoagulant or antiplatelet drugs.

ANTIDIABETES DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = B

Theoretically, taking Panax ginseng with antidiabetes drugs might increase the risk of hypoglycemia.

Details

Clinical research suggests that Panax ginseng might decrease blood glucose levels (89740). Monitor blood glucose levels closely.

Interaction Rating = Minor Be watchful with this combination.

Severity = Mild • Occurrence = Possible • Level of Evidence = D

Theoretically, Panax ginseng might decrease levels of drugs metabolized by CYP1A1.

Details

In vitro research shows that Panax ginseng can induce the CYP1A1 enzyme (24104).

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = B

Theoretically, Panax ginseng might increase levels of drugs metabolized by CYP2D6. However, research is conflicting.

Details

There is some evidence that Panax ginseng can inhibit the CYP2D6 enzyme by approximately 6% (1303,51331). In addition, in animal research, Panax ginseng inhibits the metabolism of dextromethorphan, a drug metabolized by CYP2D6, by a small amount (103478). However, contradictory research suggests Panax ginseng might not inhibit CYP2D6 (10847). Until more is known, use Panax ginseng cautiously in patients taking drugs metabolized by these enzymes.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = B

Theoretically, Panax ginseng might increase or decrease levels of drugs metabolized by CYP3A4.

Details

Panax ginseng may affect the clearance of drugs metabolized by CYP3A4. One such drug is imatinib. Inhibition of CYP3A4 was believed to be responsible for a case of imatinib-induced hepatotoxicity (89764). In contrast, Panax ginseng has been shown to increase the clearance of midazolam, another drug metabolized by CYP3A4 (89734,103478). Clinical research shows that Panax ginseng can reduce midazolam area under the curve by 44%, maximum plasma concentration by 26%, and time to reach maximum plasma concentration by 29% (89734). Midazolam metabolism was also increased in animals given Panax ginseng (103478). Until more is known, use Panax ginseng cautiously in combination with CYP3A4 substrates.

ESTROGENS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, concomitant use of large amounts of Panax ginseng might interfere with hormone replacement therapy.

Details

Laboratory research and some case reports suggest that Panax ginseng can have estrogenic effects due to competition for estrogen receptors (590,591,592,6180,10982,10983,10984). The estrogenic activity is attributed to the ginsenoside constituents of Panax ginseng (10984).

FEXOFENADINE (Allegra)

Interaction Rating = Minor Be watchful with this combination.

Severity = Mild • Occurrence = Possible • Level of Evidence = D

Theoretically, Panax ginseng might decrease blood levels of oral or intravenous fexofenadine.

Details

Animal research suggests that taking Panax ginseng in combination with oral or intravenous fexofenadine may reduce the bioavailability of fexofenadine. Some scientists have attributed this effect to the ability of Panax ginseng to increase the expression of P-glycoprotein (24101).

FUROSEMIDE (Lasix)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, Panax ginseng might reduce the effects of furosemide.

Details

There is some concern that Panax ginseng might contribute to furosemide resistance. There is one case of resistance to furosemide diuresis in a patient taking a germanium-containing ginseng product (770).

IMATINIB (Gleevec)

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, Panax ginseng might increase the effects and adverse effects of imatinib.

Details

A case of imatinib-induced hepatotoxicity has been reported for a 26-year-old male with chronic myelogenous leukemia stabilized on imatinib for 7 years. The patient took imatinib 400 mg along with a Panax ginseng-containing energy drink daily for 3 months. Since imatinib-associated hepatotoxicity typically occurs within 2 years of initiating therapy, it is believed that Panax ginseng affected imatinib toxicity though inhibition of cytochrome P450 3A4. CYP3A4 is the primary enzyme involved in imatinib metabolism (89764).

IMMUNOSUPPRESSANTS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = B

Theoretically, Panax ginseng use might interfere with immunosuppressive therapy.

Details

Panax ginseng might have immune system stimulating properties (3122).

INSULIN

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = B

Theoretically, taking Panax ginseng with insulin might increase the risk of hypoglycemia.

Details

Clinical research suggests that Panax ginseng might decrease blood glucose levels (89740). Insulin dose adjustments might be necessary in patients taking Panax ginseng; use with caution.

LOPINAVIR/RITONAVIR (Kaletra)

Interaction Rating = Minor Be watchful with this combination.

Severity = Insignificant • Occurrence = Unlikely • Level of Evidence = B

Although Panax ginseng has demonstrated variable effects on cytochrome P450 3A4 (CYP3A4), which metabolizes lopinavir, Panax ginseng is unlikely to alter levels of lopinavir/ritonavir.

Details

Lopinavir is metabolized by CYP3A4 and is administered with the CYP3A4 inhibitor ritonavir to increase its plasma concentrations. Panax ginseng has shown variable effects on CYP3A4 activity in humans (89734,89764). However, taking Panax ginseng (Vitamer Laboratories) 500 mg twice daily for 14 days did not alter the pharmacokinetics of lopinavir/ritonavir in 12 healthy volunteers (93578).

MIDAZOLAM (Versed)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = B

Theoretically, Panax ginseng may increase the clearance of midazolam.

Details

Midazolam is metabolized by cytochrome P450 3A4 (CYP3A4). Clinical research suggests that Panax ginseng can reduce midazolam area under the curve by 44%, maximum plasma concentration by 26%, and time to reach maximum plasma concentration by 29% (89734). Midazolam metabolism was also increased in animals given Panax ginseng (103478).

MONOAMINE OXIDASE INHIBITORS (MAOIs)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = D

Theoretically, Panax ginseng can interfere with MAOI therapy.

Details

Concomitant use of Panax ginseng with phenelzine (Nardil) is associated with insomnia, headache, tremors (617), and hypomania (618,23650).

NIFEDIPINE (Procardia)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = B

Theoretically, taking Panax ginseng with nifedipine might increase serum levels of nifedipine and the risk of hypotension.

Details

Preliminary clinical research shows that concomitant use can increase serum levels of nifedipine in healthy volunteers (22423). This might cause the blood pressure lowering effects of nifedipine to be increased when taken concomitantly with Panax ginseng.

QT INTERVAL-PROLONGING DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = B

Theoretically, Panax ginseng has an additive effect with drugs that prolong the QT interval and potentially increase the risk of ventricular arrhythmias. However, research is conflicting.

Details

Clinical research shows that short-term use of Panax ginseng can increase the QT interval (4322,96218). However, no changes in QT interval have been identified with prolonged use (4322).

RALTEGRAVIR (Isentress)

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, taking Panax ginseng with raltegravir might increase the risk of liver toxicity.

Details

A case report suggests that concomitant use of Panax ginseng with raltegravir can increase serum levels of raltegravir, resulting in elevated liver enzymes levels (23621).

SELEGILINE (Eldepryl)

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, Panax ginseng might increase or decrease levels of selegiline, possibly altering the effects and side effects of selegiline.

Details

Animal research shows that taking selegiline with a low dose of Panax ginseng extract (1 gram/kg) reduces selegiline bioavailability, while taking a high dose of Panax ginseng extract (3 grams/kg) increases selegiline bioavailability (103053). More research is needed to confirm these effects.

STIMULANT DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, taking Panax ginseng with stimulant drugs might increase the risk of adverse stimulant effects.

Details

Panax ginseng has been shown to have stimulant effects (589,594).

WARFARIN (Coumadin)

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Unlikely • Level of Evidence = B

Panax ginseng might affect the clearance of warfarin. However, this interaction appears to be unlikely.

Details

There has been a single case report of decreased effectiveness of warfarin in a patient who also took Panax ginseng (619). However, it is questionable whether Panax ginseng was the cause of this decrease in warfarin effectiveness. Some research in humans and animals suggests that Panax ginseng does not affect the pharmacokinetics of warfarin (2531,11890,17204,24105). However, other research in humans suggests that Panax ginseng might modestly increase the clearance of the S-warfarin isomer (15176). More evidence is needed to determine whether Panax ginseng causes a significant interaction with warfarin.

Report an Adverse Reaction to Resinall K

Adverse Effects view details

Below is general information about the adverse effects of the known ingredients contained in the product Resinall K. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.

CATECHU

General ...There is limited reliable information available about the adverse effects of catechu when used orally or topically as a single ingredient. A specific combination product (Limbrel, Primus Pharmaceuticals) containing flavonoid extracts of catechu and Baikal skullcap has been associated with serious adverse effects, including liver and lung injury.

Hepatic ...A specific combination product (Limbrel, Primus Pharmaceuticals) containing flavocoxid, a mixture of flavonoid extracts from catechu and Baikal skullcap, has been linked to several reports of acute liver damage. In a case series, four reports of liver damage were described in patients taking this product. The patients involved were females aged 54-68 years taking doses of 250-500 mg twice daily for 1-3 months. Signs and symptoms included jaundice, pruritus, abdominal pain, fever, rash, and elevated serum and liver transaminase levels. All patients fully recovered and levels normalized within 3 months after discontinuation (18009,18011). In addition to these published case reports, approximately 30 liver-related adverse events have been reported to the manufacturer of this product (18009). The mechanism of hepatotoxicity is unclear (18009,18010); it is estimated that the incidence of hepatotoxicity with this product is around 1 in 10,000, although the actual incidence is unknown (18010). In 2017, the US Food and Drug Administration (FDA) formally requested the recall of all non-expired lots of this product due to the risk for liver and lung injury (106042). It is unclear if these effects were due to catechu, Baikal skullcap, or the combination.
More recently, in another case report, a 54-year-old female reported to the emergency room with acute hepatitis possibly due to taking a preparation of catechu and Baikal skullcap for 2-4 weeks. Causation was unable to be established. After discontinuing the supplements and supportive treatment, liver function returned to normal (94563). It was unclear if the catechu product was the same specific combination product (Limbrel, Primus Pharmaceuticals) associated with previous reports of liver damage.

Pulmonary/Respiratory ...A specific combination product (Limbrel, Primus Pharmaceuticals) containing flavocoxid, a mixture of flavonoid extracts from catechu and Baikal skullcap, has been linked to several reports of hypersensitivity pneumonitis. Symptoms include fever, chills, headache, cough, chronic bronchitis, shortness of breath, weight loss, and fatigue. In 2017, the US Food and Drug Administration (FDA) formally requested the recall of all non-expired lots of this product due to the risk for liver and lung injury (106042). It is unclear if these effects were due to catechu, Baikal skullcap, or the combination.

General ...Orally, Corydalis yanhusuo is generally well tolerated.
Serious Adverse Effects (Rare):
Orally: Clonic spasms and muscle tremors with high doses.

Musculoskeletal ...Orally, clonic spasms and muscle tremors may occur with overdoses of Corydalis yanhusuo (18).

General ...No adverse effects reported; however, a thorough evaluation of safety outcomes has not been conducted.

Dermatologic ...Topically, myrrh has been reported to cause dermatitis (6).

Gastrointestinal ...Orally, myrrh may cause diarrhea in some patients when taken at doses of 2-4 grams (12,19).

Genitourinary ...Severe lower abdominal pain has been reported in a pregnant woman drinking myrrh resin dissolved in 500 mL of water twice daily as prescribed by a traditional practitioner. This adverse effect resolved one day after discontinuing myrrh. The investigators suggest that this acute abdominal pain was related to myrrh's activity as a uterine stimulant (93645).

Immunologic ...Orally, myrrh has been reported to cause severe allergic skin reactions, with redness, swelling, and itching, in two case reports of individuals using oral traditional Chinese medicines containing myrrh (101114).

Renal ...Orally, myrrh may cause kidney impairment in some patients when taken at doses of 2-4 grams (12,19).

General ...Orally, Panax ginseng is generally well tolerated when used for up to 6 months. There is some concern about the long-term safety due to potential hormone-like effects.
Topically, no adverse effects have been reported when ginseng is used as a single ingredient. However, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Insomnia.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis, arrhythmia, ischemia, Stevens-Johnson syndrome.

Cardiovascular ...Panax ginseng may cause hypertension, hypotension, and edema when used orally in high doses, long-term (3353). However, single doses of Panax ginseng up to 800 mg are not associated with changes in electrocardiogram (ECG) parameters or increases in heart rate or blood pressure (96218). There is a case report of menometrorrhagia and tachyarrhythmia in a 39-year-old female who took Panax ginseng 1000-1500 mg/day orally and also applied a facial cream topically that contained Panax ginseng. Upon evaluation for menometrorrhagia, the patient also reported a history of palpitations. It was discovered that she had sinus tachycardia on ECG. However, the patient was a habitual consumer of coffee 4-6 cups/day and at the time of evaluation was also mildly anemic. The patient was advised to discontinue taking Panax ginseng. During the 6 month period following discontinuation the patient did not have any more episodes of menometrorrhagia or tachyarrhythmia (13030). Also, a case of transient ischemic attack secondary to a hypertensive crisis has been reportedly related to oral use of Panax ginseng (89402).

Dermatologic ...Orally, Panax ginseng may cause itching or an allergic response consisting of systemic rash and pruritus (89743,89760,104953,114984,114985). Skin eruptions have also been reported with use of Panax ginseng at high dosage, long-term (3353). Uncommon side effects with oral Panax ginseng include Stevens-Johnson syndrome (596).
In one case report, a 6-year-old male with a previous diagnosis of generalized pustular psoriasis, which had been in remission for 18 months, presented with recurrent pustular lesions after consuming an unspecified dose of Panax ginseng. The patient was diagnosed with pityriasis amiantacea caused by subcorneal pustular dermatosis. Treatment with oral dapsone 25 mg daily was initiated, and symptoms resolved after 4 weeks (107748). In another case report, a 26-year-old female presented with itchy exanthem and oval erythematous lesions on the face, neck, and abdomen after consuming a decoction containing Panax ginseng, aconite, ginger, licorice, Cassia cinnamon, goldthread, and peony 400 mL twice daily for 1 week. Pityriasis rosea-like eruption was suspected, but the patient refused topical or oral antihistamines or corticosteroids. The patient continued taking the decoction but with Panax ginseng and aconite removed. After 6 days, symptoms began to resolve, and by 17 days symptom improvement was significant (114986). It is unclear if this reaction was due to Panax ginseng, aconite, the combination, or some other factor. Pityriasis rosea typically resolves spontaneously.
Topically, when a specific multi-ingredient cream preparation (SS Cream) has been applied to the glans penis, mild pain, local irritation, and burning have occurred (2537).

Endocrine ...The estrogenic effects of ginseng are controversial. Some clinical evidence suggests it doesn't have estrogen-mediated effects (10981). However, case reports of ginseng side effects such as postmenopausal vaginal bleeding suggest estrogenic activity (590,591,592,10982,10983).
In a 12-year-old Korean-Japanese male, enlargement of both breasts with tenderness in the right breast (gynecomastia) occurred after taking red ginseng extract 500 mg daily orally for one month. Following cessation of the product, there was no further growth or pain (89733). Swollen and tender breasts also occurred in a 70-year-old female using Panax ginseng orally (590).

Gastrointestinal ...Orally, Panax ginseng can cause decreased appetite (3353), constipation, diarrhea, dyspepsia (3353,89734,103477,112841,114980,114985), abdominal pain (89734,87984,112841,114985), and nausea (589,87984). However, these effects are typically associated with long-term, high-dose usage (3353). Some evidence suggests that fermented Panax ginseng is more likely to cause abdominal pain and diarrhea when compared with unfermented Panax ginseng (112841).

Genitourinary ...Amenorrhea has been reported with oral use of Panax ginseng (3353).
Topically, when a specific multi-ingredient cream preparation (SS Cream) has been applied to the glans penis, sporadic erectile dysfunction and excessively delayed ejaculation have occurred (2537). Less commonly, patients can experience vaginal bleeding (591,592,3354,23630).

Hepatic ...It is unclear if Panax ginseng is associated with adverse hepatic effects. Cholestatic hepatitis has been reported in a 65-year old male following oral use of a combination product containing Panax ginseng and other ingredients (Prostata). However, it is unclear if this adverse effect was due to Panax ginseng, other ingredients, or the combination (598). An elevation in liver enzymes has been rarely reported in clinical research (114985).

Immunologic ...A case of anaphylaxis, with symptoms of hypotension and rash, has been reported following ingestion of a small amount of Panax ginseng syrup (11971).

Neurologic/CNS ...Orally, one of the most common side effects to Panax ginseng is insomnia (589,89734,111336,114985). Headache (594,23638,112840,114985), vertigo, euphoria, and mania (594) have also been reported. Migraine and somnolence occurred in single subjects in a clinical trial (87984). In a case report of a 46-year-old female, orobuccolingual dyskinesia occurred following oral use of a preparation containing black cohosh 20 mg and Panax ginseng 50 mg twice daily for menopausal symptoms. The patient's condition improved once the product was stopped and treatment with baclofen 40 mg and clonazepam 20 mg daily was started (89735).
