Drugs for kidney deficiency should be used to nourish yin and kidney. There are both mild drugs and sweet and cold drugs, such as Fructus Lycii, Radix Polygoni Multiflori Preparata, Radix Rehmanniae Preparata, Fructus Schisandrae, Polygonatum sibiricum, Eclipta prostrata, Fructus Ligustri Lucidi, Carapax et Plastrum Testudinis, Dendrobium, Polygonatum odoratum, Cornus officinalis, American ginseng, etc. Many people regard "Liuwei Dihuang Pill" as a "secret recipe for tonifying kidney and yin". After long-term consumption, they feel more and more weak-some of the original symptoms are getting worse and worse, and some even "make up" the gastrointestinal discomfort. It is understood that the hospital "complained" about Liuwei Dihuang Pills, and most of them bought them in pharmacies as family supplements. Liuwei Dihuang Pill is effective for kidney yin deficiency, but it can't take into account the symptoms caused by yin deficiency and excessive fire. Many people report that they get angry after eating Liuwei Dihuang Pill, so they can't "eat blindly".
