GUANYIN PEARLS (90 CAPS) (CLASSICAL PEARL) The design of Guanyin Pearls reflects a unique approach to a wide array of menopausal and post-menopausal issues. It combines the conventional yin tonic approach to hot flashes with the yang tonic Qianyang Dan (Submerge the Yang Pellet), a 19th century modification of the classical Fuzi Lizhong Tang (Rectify the Middle Decoction with Aconite) by the scholar-physician Zheng Qinan, revered founder of the Fire Spirit School. https://bonafideacupuncture.com/specialty-products/classical-pearls/endocrine/guanyin-pearls-90-caps-classical-pearl-2/
