What Da Huang Zhe Chong Wan is for
This is the formula for skin that has gone dull: dusky, blotchy or mottled, dry and withered, because old stasis has thickened the Blood and stopped it nourishing the surface. It breaks that stasis with the strongest substances in the tradition while feeding the Blood the stasis has dried, so colour and texture can return slowly.
The skin sign is colour that has stopped moving. Patches look dusky, greyish or bruised without having been injured, the surface is dry and scaly, and the tissue seems thin and withered rather than plump. The change is fixed, not fleeting: it stays in the same place and deepens over months. There may be hard masses beneath the skin, and the overall impression is of a surface that has been starved of fresh Blood for a long time.
Stasis at this depth is old and dry. Blood that does not move cannot nourish, and the tissue it should feed becomes hard, dark and thin. Tu Bie Chong, Shui Zhi, Meng Chong and Gan Qi break the stasis; Da Huang and Qi Cao purge and move it downward; Tao Ren and Xing Ren move Blood and Qi; Huang Qin clears the Heat that stasis generates; Sheng Di Huang and Bai Shao restore the Blood the stasis has dried; Gan Cao harmonises. It breaks and nourishes in the same movement.
It is the strongest formula of its kind, and it is used only under professional supervision, over months, for chronic dried stasis rather than for a fresh bruise or injury. It is absolutely contraindicated in pregnancy. Any patch that is new, growing or irregular needs medical assessment before it is treated as stasis, because not every dark mark is old Blood.

The pattern behind it
The pattern is old, deep Blood stasis that has dried the Blood and depleted the surface. The stasis produces the fixed masses and the dusky mottling; the drying produces the scaly skin and the wasted appearance. The formula breaks the stasis while nourishing, which is why it suits the chronic dried picture rather than acute injury.

Patterns it treats
Blood Stagnation
Dusky, mottled or bruised-looking patches that stay fixed, on dry, scaly, withered skin. The stasis is old and the Blood has dried, so the surface is starved of colour and moisture.
How the formula is built
Strong breaking with careful nourishment. The insect and purgative group attacks the fixed stasis, while Sheng Di Huang and Bai Shao protect the Blood the stasis has already dried. That is why such a harsh formula can be given for months: it breaks and rebuilds at the same time.

Origin and history
Jin Gui Yao Lue (金匮要略, Synopsis of Prescriptions of the Golden Chamber) by Zhang Zhongjing, Eastern Han dynasty, around 220 CE.
Zhang Zhongjing recorded this formula for the most advanced form of Blood stasis: old, fixed, drying, and wasting the body. The use of insects such as ground beetle and leech reflects the view that only such substances can reach stasis that ordinary herbs cannot move, and its combination with nourishing herbs allows a long course.
Classical record
Zhang Zhongjing recorded the pill for old Blood stasis with a dry wasted appearance, breaking the stasis with insect and purgative substances while nourishing the Blood.
