• Aging. Although there has been interest in using oral deer velvet for anti-aging effects, there is insufficient reliable information about the clinical effects of deer velvet for this purpose.
• Anemia of chronic disease. Although there has been interest in using oral deer velvet for anemia of chronic disease, there is insufficient reliable information about the clinical effects of deer velvet for this purpose.
• Asthma. Although there has been interest in using oral deer velvet for asthma, there is insufficient reliable information about the clinical effects of deer velvet for this purpose.
• Athletic performance. It is unclear if oral deer velvet extract or powder is effective for improving athletic performance. Details: One small clinical study in active adult males participating in a strength training program shows that taking deer velvet extract 300 mg or deer velvet powder 1.5 grams daily for 10 weeks does not improve squat strength or aerobic capacity when compared with placebo. However, taking deer velvet might produce modest improvements in knee extension strength and endurance (47108).
• Cardiovascular disease (CVD). Although there has been interest in using oral deer velvet for CVD, there is insufficient reliable information about the clinical effects of deer velvet for this purpose.
• Cognitive function. Although there has been interest in using oral deer velvet to improve cognitive function, there is insufficient reliable information about the clinical effects of deer velvet for this purpose.
• Erectile dysfunction (ED). Although there has been interest in using oral deer velvet for ED, there is insufficient reliable information about the clinical effects of deer velvet for this purpose.
• Fatigue. Although there has been interest in using oral deer velvet for fatigue, there is insufficient reliable information about the clinical effects of deer velvet for this purpose.
• Hypertension. Although there has been interest in using oral deer velvet for hypertension, there is insufficient reliable information about the clinical effects of deer velvet for this purpose.

• Uterine fibroids. Deer velvet has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of nine small clinical trials shows that taking traditional Chinese medicine decoctions containing deer velvet or ejiao, a gelatin product extracted from donkey skin, along with other herbal ingredients plus mifepristone reduces uterine fibroid volume and improves symptoms associated with uterine fibroids when compared with mifepristone alone (106850). It is unclear if these findings are due to deer velvet, other ingredients, or the combination.
• Wound healing. Although there has been interest in using oral deer velvet for wound healing, there is insufficient reliable information about the clinical effects of deer velvet for this purpose. More evidence is needed to rate deer velvet for these uses.

POSSIBLY EFFECTIVE

• Sexual dysfunction. Oral tribulus seems to improve sexual experience in females with hypoactive sexual desire disorder (HSDD) or sexual dysfunction. Some research also shows that oral tribulus improves sexual function in males. Details: Clinical research in premenopausal and postmenopausal patients with HSDD shows that taking tribulus 250 mg three times daily (Androsten, Herbarium) for 3 months improves overall satisfaction and lubrication, as well as pain, desire, sexual arousal, and ability to reach orgasm, when compared with placebo (92027,97331,97332). Other preliminary clinical research in females with HSDD shows that taking tribulus extract 7.5 mg daily for 4 weeks improves sexual desire, arousal, satisfaction, orgasm, pain, and lubrication when compared with placebo (92022). A nonblinded clinical study comparing tribulus dosing regimens shows that taking oral tribulus 280 mg, either once daily or in three divided daily doses, for 90 days results in similar improvements in sexual dysfunction, regardless of menopausal status. However, neither dosing schedule increases clitoral blood flow when compared with baseline (108551). Tribulus has also been studied in males. One clinical study in males with erectile dysfunction, with or without HSDD, shows that taking tribulus (Tribestan, Sopharma AD) 500 mg three times daily for 3 months improves sexual desire and intercourse satisfaction when compared with placebo (97330).

POSSIBLY INEFFECTIVE

• Athletic performance. Oral tribulus does not seem to improve athletic performance. Details: Small clinical studies in athletes show that taking tribulus orally, alone or in combination with other ingredients such as androstenedione, most often as 450-770 mg daily for 5-8 weeks, does not seem to enhance body composition or exercise performance when compared with placebo or a control group (7514,13255,92029,108552).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Angina. It is unclear if oral tribulus is beneficial for angina. Details: Preliminary clinical research shows that taking a tribulus extract orally might reduce symptoms of angina when compared with a control (3931).
• Atopic dermatitis (eczema). Oral tribulus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Some preliminary clinical research shows that taking tribulus orally in combination with 9 other herbs (Zemaphyte) daily for 8 weeks reduces redness and skin lesions in adults and children with nonexudative atopic dermatitis (12627,12628). However, other research shows no effect (12630). It is unclear if these effects are due to tribulus, the other ingredients, or the combination.
• Bacterial vaginosis. Topical tribulus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with bacterial vaginosis shows that using a specific vaginal suppository (Forzajeh) containing tribulus, myrtle, fennel, and tamarind daily for 1 week is as effective as metronidazole vaginal suppository for improving vaginal discharge volume and odor, pelvic pain, cervical inflammation, and vaginal pH (100339). It is unclear if these effects are due to tribulus, the other ingredients, or the combination.
• Benign prostatic hyperplasia (BPH). Oral tribulus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with BPH shows that taking a combination supplement (Prostalyn, East India Pharmaceutical Works Ltd.) containing tribulus 600 mg and curry leaf (Murraya koenigii) 600 mg twice daily for 12 weeks improves prostate symptoms when compared to baseline, with no difference when compared to tamsulosin 400 mcg daily. This supplement also seems to reduce prostate volume by around 2 mL (92033).
• Cancer. Although there is interest in using oral tribulus for cancer, there is insufficient reliable information about the clinical effects of tribulus for this condition.
• Chronic fatigue syndrome (CFS). Although there is interest in using oral tribulus for CFS, there is insufficient reliable information about the clinical effects of tribulus for this condition.
• Diabetes. It is unclear if oral tribulus is beneficial for diabetes. Details: Preliminary clinical research in females with type 2 diabetes who are taking oral hypoglycemic agents shows that taking tribulus extract powder 500 mg twice daily for 3 months modestly reduces fasting glucose and postprandial glucose levels, but not glycated hemoglobin, when compared with placebo. However, the validity of these findings is limited by the difference in diabetes severity between groups at baseline (97327).
• Erectile dysfunction (ED). It is unclear if oral tribulus is beneficial for ED. Research is conflicting. Details: Clinical research in patients with ED shows that taking tribulus (Tribestan, Sopharma AD) 500 mg three times daily for 3 months does not provide a clinically beneficial improvement in erectile function when compared with placebo (97330). Other clinical research shows that taking tribulus 400 mg twice daily for 30 days does not improve erectile function when compared with placebo (92031). However, one preliminary clinical study in patients with partial androgen deficiency shows that taking tribulus 250 mg three times daily for 3 months improves erectile function when compared to baseline (92028). Tribulus has also been studied in combination with other ingredients. Preliminary clinical research shows that taking a combination supplement (Tradamix TX1000, Tradapharma Sagl) containing tribulus 450 mg, brown algae 300 mg, and chitosan 250 mg twice daily for 3 months improves sexual satisfaction, desire, ejaculation function, and sexual quality of life when compared with placebo in patients with mild-to-moderate ED (92030). It is unclear if these effects are due to tribulus, the other ingredients, or the combination.
• Exercise-induced muscle damage. It is unclear if oral tribulus is beneficial for exercise-induced muscle damage. Details: Clinical research in a small number of healthy, untrained males shows that taking tribulus 500 mg daily for 2 weeks prior to performing resistance exercise reduces markers of muscle damage, including creatine phosphokinase (CPK) and lactate dehydrogenase (LDH), but does not reduce levels of the inflammatory markers interleukin-6 (IL-6) or C-reactive protein (CRP), when compared with placebo (103236). However, another small clinical study in male CrossFit athletes shows that taking tribulus 770 mg capsules (Quamtrax Pharmaceuticals) daily for 42 days does not reduce CPK but does improve CRP and oxidant status when compared with placebo (111747). However, it is unclear whether any improvements are clinically significant. A very small crossover clinical study in trained male athletes shows that taking 20 mg/kg/day of tribulus in 3 divided doses 30 minutes before meals with 500 mL of water for 4 weeks does not reduce muscle soreness after intensive aerobic exercise when compared with placebo (111746).
• Gonorrhea. Although there is interest in using oral tribulus for gonorrhea, there is insufficient reliable information about the clinical effects of tribulus for this condition.
• Hypercholesterolemia. Although there is interest in using oral tribulus for hypercholesterolemia, there is insufficient reliable information about the clinical effects of tribulus for this condition.
• Hypertension. It is unclear if oral tribulus can lower blood pressure. Details: In patients with pre-hypertension, clinical research shows that taking powdered tribulus fruit 2 grams three times daily for 2 months reduces systolic and diastolic blood pressure by 6 and 5 mmHg, respectively, when compared with placebo (105245). It is unclear what effect Tribulus may have in patients with diagnosed hypertension.
• Kidney stones (nephrolithiasis). Although there is interest in using oral tribulus for kidney stones, there is insufficient reliable information about the clinical effects of tribulus for this purpose.
• Male infertility. It is unclear if oral tribulus is beneficial for male infertility; the available research is conflicting. Details: Case series suggest that taking a specific tribulus product (Tribestan, Sopharma) 250 mg three times daily for 30 days improves ejaculate volume, sperm concentration, and sperm motility in patients with infertility due to oligoasthenozoospermia (78865), and improves libido and erections in patients with primary hypogonadism (78868). Conversely, a small clinical study in patients with oligozoospermia shows that taking tribulus granules 6 grams daily for 60 days does not improve sperm count when compared with placebo (92032). In patients with idiopathic infertility, taking tribulus 250 mg three times daily for 3 months does not increase sperm concentration, sperm motility, serum testosterone levels, or luteinizing hormone levels (97328). The difference in these findings might be due to the small study sizes, as well as the variable etiology of infertility.
• Menopausal symptoms. Oral tribulus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research shows that taking a combination product containing tribulus 40 mg, ginger, saffron, and Ceylon cinnamon (Aphrodit, Goldaru Company) twice daily for 4 weeks improves mental and physical symptoms during menopause, but not genitourinary symptoms, when compared with placebo (97326). It is not clear if this effect is due to tribulus, the other ingredients, or the combination.
• Osteoporosis. Although there is interest in using oral tribulus for osteoporosis, there is insufficient reliable information about the clinical effects of tribulus for this condition.
• Polycystic ovary syndrome (PCOS). Oral tribulus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One clinical study shows that taking tribulus extract (Tribulus forte, Mediherb, Integra Healthcare Ltd) 245 mg daily along with other ingredients and lifestyle modification during the follicular phase of the menstrual cycle for 3 months improves some symptoms of PCOS, including a 33% reduction in oligomenorrhea or amenorrhea and a 43-day reduction in the duration between menstrual cycles, when compared with lifestyle modification alone. Taking tribulus with other ingredients also improves quality of life by about 30% and reduces body mass index by 1 kg/m2 when compared with placebo. Although the conception rate increased 4-fold in patients taking the combination product, the live birth rate was similar to those taking placebo. (97216). It is unclear if these effects are due to tribulus, the other ingredients, or the combination.
• Premature ejaculation. Oral tribulus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a combination product containing tribulus, 5-HTP, winter savory, and chanca piedra (EiacuMev, Farmaceutica Mev) daily for 3 months improves time to ejaculation by 30 seconds and reduces symptoms related to premature ejaculation when compared to control (97016). More evidence is needed to rate tribulus for these uses.
