Mammary rock

Also mammary chestnut. A disease of the breast that starts as a hard, painless mammary node the size of a jujube or chestnut with an uneven surface, and that subsequently grows larger and becomes painful. Before bursting, the nipples become sunken and the lump feels like a heap of chestnuts or an upturned bowl and is connected with the skin so that it does not move when pushed. If the head shows through as purple, it will gradually rupture to leave an opening like a rock cave that exudes foul water or blood.

Biomedical correspondence: adenocarcinoma of the breast. It is attributable to thought and anxiety causing counterflow of liver spleen-qì.

Medicinal therapy: Treat by coursing the liver and rectifying qì with formulas such as Free Wanderer Powder (逍遥散 xiāo yáo sǎn).
