Most of the aphrodisiacs in Chinese medicine are warm in nature and are not recommended to be used regularly if there is no yang deficiency per se, and long-term use of them may lead to manifestation of heat. Common aphrodisiacs in traditional Chinese medicine include antler velvet, epimedium, dried ginger, cistanchis, etc. These drugs can serve to tonify the kidneys and strengthen yang (the action of tonifying the kidneys and yang), and are mainly used for treating various manifestations caused by renal yang insufficiency (lack of yang in kidneys), such as lumbar and knee soreness (the feeling of aching and weakness of lumbar area and knees), cold hands and feet, whitish complexion, clear and long urination, and impotence and premature ejaculation. However, this kind of medicine should be stopped in time after the recovery of the disease, because the nature of the medicine itself is warm and hot, and its frequent use may lead to excessive yang qi in the body, with manifestations of heat such as dry mouth, constipation, yellow urine, and so on. Specific medication is recommended to consult a doctor, not self-medication, so as not to delay the condition.
