Dad always asked me to buy him Liuwei Dihuang pills, saying that they could tonify the kidney. What medicinal materials does this medicine consist of and what effect does it have?

How can I put it? The theory of tonifying kidney is a bit incomplete. Kidney deficiency is divided into kidney yin deficiency and kidney yang deficiency, which is mainly used to nourish kidney yin and is not suitable for patients with kidney yang deficiency. So I suggest you take dad to see a doctor and take medicine on the doctor's advice.

2. This prescription consists of three tonic drugs, namely Radix Rehmanniae Preparata, Cornus officinalis and Rhizoma Dioscoreae, and three laxatives, namely Alisma orientalis, Cortex Moutan and Poria. The dosage of tonics is greater than that of laxatives, and it has the characteristics of "three tonics and three purges", but it is mainly tonic and mild in nature.

These six medicines complement each other, and the effect of nourishing yin and tonifying kidney is still very good.

If you really need advice, you can look at Zhongjing's, which is the following one.

I hope my answer can help you! ! Hope to adopt! !
