Which herb is indicated for infertility and erectile dysfunction, with aphrodisiac and diuretic actions?

• A. Pulsatilla vulgaris
• B. Quercus rubra
• C. Tribulus terrestris
• D. Salvia officinalis

Answer: (C)

The key idea is identifying an herb traditionally used to boost male sexual function, combining aphrodisiac action with a diuretic effect. Tribulus terrestris fits this profile best. Its active steroidal saponins, especially protodioscin, are linked to enhancing sexual desire and performance, and they’re thought to support androgen activity in a way that can benefit infertility and erectile dysfunction. The diuretic property adds a second action that aligns with traditional indications for improving overall reproductive health by promoting smooth renal and urinary function. Compared to the other plants, which have different primary uses or safety concerns (Pulsatilla vulgaris is highly toxic and not used for this purpose; Quercus rubra is mainly astringent; Salvia officinalis is used more for digestive and cognitive/menopausal contexts), Tribulus terrestris is the best fit for infertility with erectile dysfunction and aphrodisiac plus diuretic actions.
