Zuo Gui Wan (Zuo Gui Pian, Zuo Yui Yin 左归片) is a well regarded Chinese herbal formula dated 400 years ago. Today, it is commonly used as an herbal remedy for sexual wellness, lower back pain support and other concerns resulting from kidney Yin deficiency, which can be shown as sweat, low fever, dizziness, tinnitus, emission, soreness in the lower back.

Functions:
In Traditional Chinese Medicine (TCM), Zuo Gui Wan reinforces the kidney and nourishes Yin of the Yin-Yang principles. Yin and Yang are the opposing principles that depend on each other for existence within any subject as a whole, such as female and male for mankind, dark and light for a complete day, negative and positive for numbers. A robust interaction and balance of Yin-Yang forms the basis of a good health. The kidney is the innate foundation of all organs with respect to the Yin-Yang principles, Qi essence etc.
How Zuo Gui Wan works in modern biomedical terms is still not clear. However, some researches suggest that it increases markedly the production of male sex hormone testosterone in mice and human patients with kidney Yin deficiency and promotes the development and growth of testes and uterus.¹
Zuo Gui Wan is indicated in China Pharmacopoeia² for Yin deficiency of kidney; weakness and soreness of the loins and the knees; sweating; lassitude; dry mouth and throat.

Zuo Gui Wan is mainly applied for:
• Sexual wellness. It is used for loss of sex desire and energy and failure to sustain firm erection in association with the weakness and soreness of the loins and knees,seminal emission, dizziness, and tinnitus.
• Persistent Back Pain due to the kidney Yin deficiency. The pain typically gets heavier after overwork but relieved after rest and is accompanied with dizziness, tinnitus, sweat and emission.
• Female infertility. In a clinical study, 48 infertile female who suffered kidney deficiency in TCM's terms were treated with Zuo Gui Wan or You Gui Pian. 35 female got pregnant after 1 year. ¹
