There is no such thing as “what is the most effective way to treat impotence and premature ejaculation”. You can relieve the symptoms of impotence and premature ejaculation by using Cistanchia and Epimedium to soak in water, but the efficacy of the Chinese herbal medicine soaking in water is limited and it is difficult to achieve the purpose of treating the disease. 1. Cistanchis: It has the effect of tonifying kidney yang, benefiting essence and blood, moistening the intestines and relaxing the bowels. It is used for treating kidney yang deficiency (lack of yang energy in the kidneys), loss of essence and blood, impotence, infertility, soreness of waist and knees, weakness of tendons and bones, and intestinal dryness and constipation. It should not be taken by those who are suffering from yin deficiency and fire (deficiency of yin and essence in the body and hyperactive fire) and loose stools (thin and unshaped feces) and diarrhea. This product is not suitable for people with solid heat in the stomach and intestines, and constipation with heat knot. 2. Epimedium: It has the effect of tonifying kidney yang, strengthening muscles and bones, and dispelling wind-dampness. It is used for the treatment of kidney yang deficiency, impotence and spermatorrhea, and impotence of muscles and bones, etc. It is not recommended for people with yin deficiency and fire. It is not to be used by people with yin deficiency and fire exuberance. It is very difficult to utilize the full efficacy of Chinese herbal medicine in water, and it cannot replace the medication to treat the disease. If you need to use the above drugs need to be standardized under the guidance of traditional Chinese medicine, not self-medication.
