Patient's question:
Erectile dysfunction, short duration. Impotence and premature ejaculation.Doctor's answer:
Commonly used tonifying Yin herbs such as Shengdi, Maidong, Ejiao, Baishao, Baihe, Shihu, and Yuzhu are primarily used to formulate prescriptions. Yin deficiency leads to Yang hyperactivity, where water fails to control fire, resulting in internal heat. Therefore, the prescriptions often include herbs like Zhimo and Huangbai to clear internal heat. Representative formulas include Liuwei Dihuang Wan, Dabu Yin Wan, Yiguian Jian, and Baihe Gujin Tang.
