Ginseng has been used in traditional Chinese medicine to treat sexual dysfunction and enhance sexual behavior. It contains ginsenosides, which are the main active components that may be responsible for ginseng's effects on sexual health:

Dilates arteries
Ginsenosides can increase blood flow to the genitals, which may improve erections in men and lubrication and clitoral sensitivity in women.

Stimulates nitric oxide
Ginsenosides may stimulate the release of nitric oxide, which is important for sexual function.
Affects the central nervous system
Ginseng may affect the central nervous system, which may alter the activity of hypothalamic catecholamines that are involved in hormone secretion and copulatory behavior.

Some studies have found that ginseng may improve sexual function:

Men
A review of studies found that ginseng may improve men's self-reported ability to have intercourse.

Women
A study found that red ginseng improved sexual functioning in women, and a 2020 study found that ginseng improved sexual functioning in menopausal women.
Methadone users
A study found that ginseng improved sexual function in people taking methadone to treat opioid addiction.
