Sheng Gan Di Huang (Radix Rehmanniae Preparata, Fresh), Dang Gui (Radix Angelicae Sinensis), Du Huo (Radix Angelicae Pubescentis), Wu Zhu Yu (Fructus Evodiae), Shao Yao (Radix Paeoniae Alba/Galerae), Gan Jiang (Rhizoma Zingiberis Preparatum), Gan Cao (Radix Glycyrrhizae), Gui Xin (Cortex Cinnamomi), Xiao Cao (Herba Glehniae) (each 1 liang), Xi Xin (Herba Asari) (0.5 liang).

The above herbs are ground into a powder. Each dose is 0.5 liang. Add three zhan of water, decoct until one zhan remains, remove the dregs, and take while slightly warm. Commentary: Postpartum heart pain, although not a common disease of the puerperium, pain may have nine types, which may not necessarily be blood stasis pain. If it were treated with Yan Mi Tang, how could Shu Di Huang (Prepared Radix Rehmanniae) be used? Shu Di Huang is cloying and tends to obstruct blood circulation; how can it relieve pain? This formula originally comes from *Qian Jin Fang*, using Sheng Gan Di Huang. One sheng of Wu Zhu Yu is equivalent to five liang, three liang of Gan Jiang, and three liang of Xi Xin, treating chronic cold in the Lower Jiao (Lower Burner). The original formula dosage is one liang, but here it is halved to half a liang. This follows the principle of odd/even prescription composition, measuring the depth of the disease, with its own standards; one must not arbitrarily add or subtract. However, using Yan Mi Tang to treat blood stasis pain is not as effective as using Shi Xiao San (Pulse-Checking Powder).

Treats severe heart and abdominal pain that feels like death, where all other medicines fail; taking this formula brings immediate relief. It is largely similar to Zi Jin Wan (Purple Gold Pill) discussed in the eighth treatise. (See Treatise 8 of this volume.)

Wu Ling Zhi (Excrement Trogopteri), Pu Huang (Pollen Typhae) (equal parts).

The above herbs are ground into powder. First, mix two qian with strong vinegar and boil into a paste. Add one zhan of water, decoct until seven fen remain, and take hot before meals. This is verified to be effective.

Treats postpartum heart pain; this is a formula designed for severe cold.

Shu Jiao (Fructus Zanthoxyli), Shao Yao (Radix Paeoniae Alba/Galerae) (3 liang), Ban Xia (Rhizoma Pinelliae), Dang Gui (Radix Angelicae Sinensis), Gui Xin (Cortex Cinnamomi), Ren Shen (Radix Ginseng), Gan Cao (Radix Glycyrrhizae), Fu Ling (Sclerotium Poriae) (each 2 liang), Sheng Jiang Zhi (Jucius Zingiberis Recens) (5 he), Mi (Mel) (1 sheng).

Cut the herbs. Add nine sheng of water, boil Shu Jiao until boiling; then add the other herbs, decoct to obtain two and a half sheng, remove dregs; add Sheng Jiang Zhi and Mi, etc., and decoct again to obtain three sheng. Take five he to six he per dose. (*Qian Jin Fang* records the same.)

Discussion: What causes postpartum lochia不尽 (incomplete discharge) accompanied by abdominal pain? The answer is: Although postpartum evil blood (lochia) usually flows smoothly, if due to external contraction of the Five Pathogens (Wind, Cold, Summerheat, Dampness, Dryness) or internal injury from the Seven Emotions, the flow is suddenly interrupted; residual blood stagnates and accumulates, becoming blocked and unable to circulate, so the discharge is incomplete, thus causing abdominal pain. *Chan Bao* states: All cases arise because during pregnancy, one exposed oneself to wind and sought coolness, causing cold in the Ba Luo (Uterine Collaterals). By the time of delivery, the blood volume must be scant. Or, if one exposes oneself to wind and coolness immediately after childbirth, wind-cold combats with the blood, causing the blood to stagnate and fail to circulate freely. Accumulating internally, sometimes the lochia is not completely discharged, thus causing abdominal pain.
