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 Qin’an, revered founder of the Fire Spirit School. Zheng Qin’an and his remaining disciples interpret hot-flashes and other signs of upward mobility in the elderly as a leaking of the Kidney battery, which requires a drawing back of the life force into the lower dantian. This downward anchoring effect is accomplished by combining aconite and amomum. In younger women, Guanyin Pearls can be used for fertility issues, but should be discontinued as soon as pregnancy has been achieved.
