Tonify kidney and secure essence; tonify spleen to check diarrhea, dry dampness and stop leukorrhagia.

Indications

A. Seminal emission and spermatorrhea

It can tonify kidney to secure essence. For seminal emission and spermatorrhea, soreness and limpness of knees and lumbar due to insecurity of kidney qi, it is combined with Jin Ying Zi for mutual reinforcement of astringency, such as in the formula Shui Lu Er Xian Dan from Ren Chun Tang Jing Yan Fang. It is also combined with kidney-tonifying and astringing herbs. For instance, it is used with Lian Zi, Lian Xu and Mu Li in the formula Jin Suo Gu Jin Wan from Yi Fang Ji Jie.

B. Chronic diarrhea due to spleen deficiency

It can both tonify spleen and dry dampness, and astringe intestine to check diarrhea. For chronic diarrhea due to spleen deficiency with excessive dampness, it is combined with Bai Zhu, Fu Ling and Bai Bian Dou.

For thin leukorrhagia due to kidney and splecn deficiency, it is combined with herbs to tonify spleen qi. For instance, it is used with Dang Shen, Bai Zhu and Shan Yao. For yellow and thick leukorrhagia, it is combined with heat-clearing and damp-draining heabs.
