Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Cnidium (Cnidium monnieri) is primarily used in traditional Chinese medicine (TCM) to support male reproductive health, particularly for issues related to sexual function such as impotence and low libido. The seeds, known as "She Chuang Zi," have a long history of use as an herbal aphrodisiac and are thought to "tonify" kidney yang, which is associated with sexual vitality in TCM theory. Historical texts describe its use for increasing libido, improving erectile function, and addressing male infertility.

Scientific studies on cnidium’s effects on the male reproductive system are limited, but some preclinical research suggests that its active compounds, such as osthole, may enhance nitric oxide production and improve blood flow, potentially aiding erectile function. However, most evidence comes from animal studies or in vitro experiments, not robust human clinical trials. Thus, while traditional use is well documented and there is some preliminary pharmacological support, high-quality scientific validation in humans is lacking.

Overall, cnidium’s use for male reproductive health is primarily justified by tradition, with a moderate level of supporting evidence from laboratory research but insufficient human data to rate it higher.
