Menopause is a normal physiological change that occurs in women between the ages of 45-55 when their menstrual cycle stops. Menopause is considered complete when a year has elapsed without menstruation. This change is usually gradual and happens when a woman' ovaries stop producing eggs. Menopause disrupts the balance of the body' hormones: estrogen and progesterone. This imbalance may cause symptoms such as hot flashes, night sweats, sleeplessness, mood swings, and restlessness.

Estrogen is considered a Yin type hormone in traditional Chinese medicine (TCM). When the body stops producing estrogen, it results in a relative deficiency of Yin, often causing bothersome Heat signs. Geng Nian An Pian helps to minimize hot flashes and restlessness by clearing Heat caused by Yin deficiency, nourishing Yin (especially Kidney Yin which is closely associated with aging) and calming the mind.

Geng Nian An Pian is composed of 15 Chinese herbs which effectively clear heat and tonify the Yin to balance the body and relieve the symptoms associated with menopause.

Geng Nian An Pian contains four of the primary herbs found in Liu Hui Di Huang Wan, which is among the most regarded formulas in TCM used to tonify Yin and address symptoms often associated with the aging process. The chief herb of both formulas is Shu Di Huang (prepared Rehmannia root), a powerful Yin and blood tonic that especially benefits the Kidneys and Jing (essence). Fu Ling (Poria) is used to calm the spirit (Shen) and strengthen the Spleen to help digest the other Yin nourishing ingredients in the formulas. Ze Xie (Plantain rhizome) clears deficiency fire from the Kidneys. Mu Dan Pi (Tree Peony bark) clears heat due to Yin deficiency or heat in the blood.

Sheng Di Huang (Rehmannia root) is the unprocessed Rehmannia root. Compared to the prepared root, it has a strong property of clearing heat, cooling the Blood, and generating fluids. Mai Dong (Ophiopogon tuber) nourishes Yin and generates fluids. The important Yin tonic clears heat from the Heart and calms the spirit. Together, these herbs act to help with hot flashes.

Zhen Zhu Mu (Mother of pearl) calms the Liver and anchors Yang, which can become ascendant as a result of Yin deficiency. Zhen Zhu Mu also clears fire from the Heart. Shou Wu Teng (Polygonum vine), nourishes the Heart and calms the spirit. Gou Teng (Uncaria hook) extinguishes Liver wind and calms the spirit. Ci Shi (Magnetitum) is an important mineral in Chinese medicines that tranquilizes the mind.

Wu Wei Zi (Schisandra fruit) is an astringent medicinal herb used to reduce sweating, secure Jing (essence) and calm the Heart and spirit (Shen). Wu Wei Zi is particularly effective at reducing night sweating when combined with Xuan Shen (Figwort root) and Fu Xiao Mai (Blighted wheat). Xuan Shen also clears heat and nourishes Yin while Fu Xiao Mai specifically addresses night sweating from Yin deficiency and benefits the Qi.

He Shou Wu (Polygonum root) tonifies Jing (essence) and nourishes the blood of the Liver and Kidneys. He Shou Wu is warm but not drying and is tonifying but not cloying.

Xian Mao (Curculigo rhizome) tonifies the Kidney Yang and strengthens tendons and bones. It is used to balance the action of other Kidney Yin tonic herbs in the formula.
