Fenugreek

A recent Australian study suggests men who consumed fenugreek, a spice commonly used in Asian and Indian cuisines, experienced significantly boosted libido. Add toasted seeds to curries or simmer with chai spices as tea.

Maca root

This Peruvian herbal remedy is believed to increase estrogen levels, decrease cortisol, and reduce the risk of anxiety, depression, and sexual dysfunction—especially in postmenopausal women. Studies showed positive results when participants took 3,500 mg dried, powdered maca root per day.

Ginseng

Ginseng raises energy levels, increasing sex drive in men and women. One study involving 135 people found that those who took 900 mg Korean red ginseng three times per day experienced significantly better sexual function compared with those who took a placebo.
