Those who are weak in yin and yang can drink Cistanche Chaste Tea or Mulberry Lock-Yang Tea and so on. All of the above teas can play a role in replenishing both yin and yang. However, it should be noted that Chinese medicine mainly works by decocting, and drinking it in water may affect the therapeutic effect due to the limited release of active ingredients. 1. Cistanchis and Chasteberry Tea: Brew Cistanchis and Chasteberry with boiling water and drink. Cistanchis has the effect of tonifying kidney and yang, benefiting essence and blood, moistening the intestines and laxatives, while chasteberry can nourish the liver and kidney, brighten the eyes and darken the hair. Combining the two together can tonify both yin and yang, and the medicinal properties of the two are gentle, nourishing yin without hurting yang, and warming yang without damaging yin, which is suitable for those with yin and yang deficiencies. 2. Mulberry Lock Yang Tea: made from mulberry and lock yang brewed with boiling water. Mulberry can nourish yin and replenish blood (nourish the blood in the body), generate fluids and moisturize dryness, which is suitable for people with yin deficiency of liver and kidney (deficiency of yin and fluid in the liver and kidneys), while lock yang has the effect of replenishing yang of the kidney and benefiting the essence and blood, which is suitable for people with yang deficiency of the kidney (lack of yang of the kidneys), and when the two are used together, it can replenish yin and yang at the same time to alleviate the symptoms of yin and yang deficiencies. In addition, the above two teas are made of Chinese medicines with medicinal properties, and should be used after identification by a Chinese medicine practitioner, not blindly self-medication.
