Liuwei Dihuang Pills were created by Qian Yi, a famous pediatrician in the Northern Song Dynasty, by removing "guizhi" and "fuzi" from the Shenqi Pills in the Golden Kui Yaolue. The original name of the pills was "dihuang pills", and the remaining ingredients and their dosage ratios still follow the original recipe.
"Liuwei Dihuang Pills" can be said to be the classic core prescription of "nourishing yin and tonifying the kidney", and is mainly used to treat "kidney yin deficiency syndrome".

Because "kidney is the root of the body", and kidney yin is the root of the body's yin fluid, "kidney yin deficiency" is not only the most serious of all yin deficiency symptoms, but also often changes into various complex symptoms, so the ancients said "of the five internal organs, the kidney is the most serious." When kidney yin is insufficient, the essence is deficient and the marrow is insufficient, the bones are not nourished, so the waist and knees are sore and weak, and the teeth are shaking. The brain is the sea of marrow. When kidney yin is deficient, the marrow sea is empty, the liver blood is insufficient, and it cannot nourish the head and eyes, so dizziness and vertigo occur.

Who is suitable for Liuwei Dihuang Pills and what are the contraindications?
Normal people without any disease should not take it for a long time.
Kidney deficiency is divided into two types: kidney yin deficiency and kidney yang deficiency. Liuwei Dihuang Wan is for patients with kidney yin deficiency ;
The main symptoms of kidney yin deficiency include: soreness of waist and knees, dizziness, tinnitus, deafness, sweating and spermatorrhea, etc. If people with kidney yang deficiency take Liuwei Dihuang Pills, it will make the situation worse.
Although Liuwei Dihuang Wan is a Yin-tonifying medicine, the prescription contains a lot of Yin-nourishing medicines. People with poor stomach function will have difficulty digesting it after taking it. Therefore, even if you have kidney Yin deficiency, but your spleen and stomach function is not good, it is not recommended to take it.
Traditional Chinese medicine believes that obese people have more dampness, and dampness can hinder the spleen. Therefore, people with a slightly overweight body should not take Liuwei Dihuang Pills for "replenishment" casually.
People with poor liver and kidney conditions should not take this medicine.
