Yin Yangzi is a single medicinal material. It has the functions of nourishing the kidneys and strengthening yang, dispelling wind and dampness, and strengthening the body. It is named because it can be used by both men and women but has different effects.
When used by men, it has the effects of replenishing qi and blood, stabilizing sperm and reducing urination, and is used for male diseases such as liver and kidney blood deficiency, insufficient yang qi, backache and backache; when used by women, it can replenish qi, regulate menstruation, reduce swelling and detoxification, and nourish the body. It cools the blood, replenishes deficiency, strengthens the body, and moisturizes black hair. I don't know if there are any pharmacies.
