The effects of Right Return Pill are mainly to warm the kidneys and strengthen the yang, fill the sperm and stop the emission of sperm, which is often used for a series of symptoms of kidney yang deficiency. It is important to note that it should be distinguished from Zuo Gui Wan. The function of Zuo Gui Wan is mainly to nourish the kidney and nourish Yin, fill the marrow and is often used for symptoms of kidney Yin deficiency. The first six flavors of these two medicines are the same, but in fact, the Right Return Pill is made by removing some of the Yin nourishing medicines from the Left Return Pill and adding some of the pungent and warming Yang tonifying medicines. The symptoms of the disease are different. Zuo Gui Wan is commonly used for true Yin deficiency, soreness and weakness of the waist and knees, spermatorrhea and night sweats, while Right Gui Wan is commonly used for kidney Yang deficiency, failure of the vital gate fire, soreness and weakness of the waist and knees, and mental discomfort, etc. These symptoms sound more argumentative, so for taking Chinese medicines, it is still recommended to consult a Chinese medicine practitioner or herbalist before using them to identify the disease and use the medicine to get rid of it. If not, this will easily lead to drug abuse, if abuse is not only not able to treat the disease, may be counterproductive.
