Does Anshen Buxin Wan tonify yin deficiency or yang deficiency?

Generally speaking, Anshen Buxin Wan is primarily used to address yin deficiency. A detailed analysis follows:

Anshen Buxin Wan consists mainly of traditional Chinese medicinal herbs including Salvia miltiorrhiza (Danshen), Schisandra chinensis (Wuweizi), Acorus tatarinowii (Shichangpu), Albizia julibrissin bark (Hehuanpi), Cuscuta chinensis (Tusizi), Eclipta prostrata (Mo Han Lian), Ligustrum lucidum (Nvzhenzi), Polygonum multiflorum stem (Shouwuteng), Rehmannia glutinosa (Dihuang), and Concha Margaritifera (Zhenzhumu). Among these, Rehmannia glutinosa nourishes yin, enriches blood, and replenishes essence and marrow; Ligustrum lucidum and Eclipta prostrata nourish the yin of the liver and kidneys; although Cuscuta chinensis has a function of tonifying kidney yang, in this formula it is combined with numerous yin-nourishing herbs, thereby primarily exerting a dual yin-yang tonifying effect—with emphasis on yin nourishment.

Through synergistic action, these herbs endow Anshen Buxin Wan with the functions of nourishing yin and blood and calming the mind and spirit. It is primarily indicated for symptoms such as palpitations, dizziness, tinnitus, and insomnia caused by yin deficiency and blood insufficiency. In patients with heart yin deficiency or liver-kidney yin deficiency, it helps nourish yin fluids, subdue deficient fire, and calm the mind—thereby alleviating associated symptoms.

In clinical practice, Anshen Buxin Wan is commonly employed for conditions related to yin deficiency; however, specific use must be individualized according to each patient’s condition and administered under the guidance of a qualified physician.
