Zhi Bai Di Huang Wan (知柏地黄丸) has the effect of nourishing yin and lowering fire (nourishing yin essence and lowering fire). It is used for hot flashes (a burst of heat), night sweating, dry mouth and sore throat, tinnitus, spermatorrhea, and short and red urine (small amount of urine, dark yellow in color) caused by yin deficiency and excessive heat (deficiency of yin essence in the body, resulting in hyperactivity of deficiency fire).
