Cistanche has no role in promoting the growth of the spongy body. Because the human cavernous body is regulated by androgens from infancy until puberty, it has completed its development before the age of 18, and it does not develop twice in adulthood, so no drug will have such an effect. The western pharmacological research shows that Cistanche mainly acts on the adrenal glands, stimulating the secretion of corticosteroids, so it improves the patient’s symptoms of Yang deficiency, it does not act on the spongy body to make it bigger and stronger.
