    TRIBULUS Overview Information

    Tribulus is a plant that produces fruit covered with spines. Rumor has it that tribulus is also known as puncture vine because the spines are so sharp they can flatten bicycle tires. People use the fruit, leaf, and root as medicine.

    People use tribulus for conditions such as chest pain, eczema, enlarged prostate, sexual disorders, infertility, and many others, but there is no good scientific evidence to support these uses.

    How does it work?

    Tribulus has chemicals that might increase levels of some hormones. However, it doesn't appear to increase male hormones (testosterone) in humans.

    TRIBULUS Uses & Effectiveness What is this?

    Possibly Ineffective for:

    • Enhancing athletic performance. Taking tribulus by mouth, alone or with other herbs and supplements, doesn't seem to enhance body composition or exercise performance in athletes.

    Insufficient Evidence for:

    • Chest pain (angina pectoris). Early research shows that taking tribulus extract by mouth might reduce symptoms of angina.
    • Eczema (atopic dermatitis). Taking tribulus by mouth in combination with 9 other herbs might reduce redness and skin outbreaks in adults and children with a certain type of eczema. However, some research shows no benefit.
    • Enlarged prostate (Benign prostatic hyperplasia; BPH). Early research shows that taking a supplement containing tribulus and curry leaf (Murraya koenigii) for 12 weeks improves symptoms similar to the prescription drug tamsulosin in men with an enlarged prostate. Other early research shows that taking a supplement containing tribulus, brown algae, chitosan, and saw palmetto for 2 months improves symptoms and quality of life in men with lower urinary tract symptoms, with or without BPH.
    • Erectile dysfunction (ED). Some early research shows that taking tribulus for 3 months improves erections in men with a condition called partial androgen deficiency. Men with this condition often have ED. Other early research shows that taking a supplement containing tribulus, brown algae, and chitosan for 3 months improves sexual satisfaction, desire, ability to ejaculate, and sexual quality of life in men with ED. However, other research shows that taking tribulus for 30 days does not improve erections in men with ED.
    • Infertility. Research on tribulus for infertility is conflicting. Some early research shows that taking tribulus for 60 days does not improve sperm count in men with low sperm count. However, other research shows that taking a specific tribulus product for 30 days improves ejaculate volume, sperm concentration, and sperm movement in men with low sperm count and defective sperm movement. Other research shows that taking the same tribulus product for 1-2 months may increase sexual desire and erections in some men with infertility due to low levels of testosterone.
    • Sexual problems in women. Early research shows that taking tribulus for 4 weeks improves sexual desire, arousal, satisfaction, orgasm, pain, and lubrication in women with low sexual desire. Other early research shows that taking tribulus for 90 days improves sexual desire, arousal, sensation, lubrication, ability to reach orgasm, and sexual comfort in postmenopausal women with sexual problems.
    • "Tired blood" (anemia).
    • Cancer.
    • Coughs.
    • Intestinal gas (flatulence).
    • Other conditions.
    More evidence is needed to rate the effectiveness of tribulus for these uses.
