You Gui Wan

What You Gui Wan is for

The skin this pill is for has gone cold: pale, thin and slow to renew, with dusky extremities and a surface that heals and regrows slowly. Yang and Essence are both low, so the body cannot warm the surface or supply the material for repair, and the skin looks older and more depleted than the person's years. The formula warms the Yang and fills the Essence, which is why it works over months rather than on a single lesion.

The colour is the first clue: pale, with a grey or dusky cast at the fingers, toes and lips, and a surface that is cool to the touch even in a warm room. The skin is thin and dry, heals slowly from small injuries and marks easily, and hair and nails grow slowly and look thin. There is no redness and no heat, and the surface does not thicken or scale. It is a quiet, cold, undernourished picture, and it has usually been present for a long time.

Zhi Fu Zi and Rou Gui warm the Yang at the root, which is what reaches the surface as warmth and colour. Lu Jiao Jiao is the strongest Essence tonic in the formula and supplies the material for renewal of tissue, hair and bone, while Shu Di Huang, Shan Zhu Yu, Shan Yao, Gou Qi Zi, Tu Si Zi and Dang Gui rebuild the Essence and Blood that give the skin its substance. It is rich and warming throughout, so nothing in it is cooling or drying.

It is used for the deep cold depleted picture, over weeks, and it is not for skin that is red, hot or dry from Yin deficiency, where the warming would make matters worse. It contains Fu Zi, which is toxic unless it is correctly prepared and dosed, so it is prescribed and supervised rather than taken independently, and it is contraindicated in pregnancy. Cold extremities that come with chest pain or breathlessness need urgent assessment rather than a warming course.

The pattern behind it

The pattern is Kidney Yang and Essence deficiency. The Yang warms and drives, the Essence underlies growth and repair, and when both are low the body is cold, weak and slow to renew its tissue. The formula warms the Yang and fills the Essence, which is why it is used for the cold depleted picture rather than for heat or dryness.

Patterns it treats

How the formula is built

The formula warms and fills at the same time. Fu Zi and Rou Gui warm the Yang, Lu Jiao Jiao and the nourishing group fill the Essence and Blood, and Dang Gui keeps it moving. That combination is why it is used for deep cold depletion rather than for a single deficiency, and why it requires supervision.

Origin and history

Jing Yue Quan Shu (景岳全书, The Complete Works of Jingyue) by Zhang Jingyue, Ming dynasty, 17th century.

Zhang Jingyue created Zuo Gui Wan and You Gui Wan as a pair, named after the left and right Kidneys of the classical model: one to enrich the Yin and one to warm the Yang. You Gui Wan became the standard warming Essence tonic, used for the deep cold depletion that shows on the skin as pallor, coldness and slow renewal.
