Regarding the etiology, for those whose malaria has persisted for a long time without recovery, both the exterior and interior become deficient, pathogenic factors remain unresolved, and true qi fails to recover. Therefore, although the disease may temporarily subside, it recurs with slight exertion.
(From Volume 11)
*Zhouhou Beiji Fang* (Emergency Prescriptions Kept in the Sleeve) treatment for Labor Malaria: Biejia Wine Decoction.
Bie Jia (Turtle Shell, two liang, roasted until yellow) Chang Shan (Dichroa Root, three liang) Shu Qi (Eryngii Rhizome, two liang) Ou Zei Yu Gu (Cuttlebone, one liang, roasted) Fu Zi (Prepared Aconite Root, one liang)
Zhi Mu (Anemarrhenae Rhizoma, two liang) Jiao (Szechwan Pepper, one liang, processed to release moisture)
The above seven herbs are chopped, soaked in three dou of wine overnight. Take one ge at dawn, gradually increasing to two ge, taken three to four times daily. Avoid eating amaranth, raw scallions, raw vegetables, and pork. (All from Volume 1)
Qianjin Fang states that for Labor Malaria persisting for a long time where various treatments have failed, this formula is effective.
Take Chang Sheng Da Niu Xi (Achyranthes Root, a handful measured by the tiger's mouth), chop it, boil in six sheng of water until reduced to two sheng. Divide into two doses. The first dose should be taken about one meal's time before the attack; the second dose should be taken just before the onset. (Zhang Wenzhong's *Zhouhou* also cites this from Volume 10)
Ji Yan Fang treats all types of malaria and Labor Malaria, regardless of duration: Awie San and Wan Formula.
Awie (Asafoetida) Anxi Xiang (Benzoin) Luo Bo Zi (Radish Seed, two liang each) Wu Yi (Chaulmoogra Seed, one he)
The above four herbs are pounded and sifted into powder. Take half a qian with warm water. If powder cannot be taken, form pills with honey and swallow thirty pills with cooked water; vomiting will occur shortly after. Avoid cold water. If vomiting persists, consume pickled vegetable juice. Additionally, tie a sachet containing one qian of the powder to the arm—left side for men, right side for women—for immediate recovery. (From Volume 3)
Zhang Zhongjing's *Shanghan Lun* records: Malaria characterized predominantly by chills is called Pin Malaria (Yin Malaria), treated primarily with Musli Tang.
Mu Li (Oyster Shell, four liang, calcined) Ma Huang (Ephedrae Herba, four liang, nodes removed) Gan Cao (Licorice Root, three liang, roasted) Shu Qi (Eryngii Rhizome, three liang; if unavailable, use Chang Shan/Dichroa Root as substitute)
The above four herbs are chopped. First, wash Shu Qi three times with water to remove the fishy odor. Use eight sheng of water to decoct Shu Qi and Ma Huang, skimming off the foam until six sheng remain. Add the remaining two herbs and decoct further until two sheng remain. Strain and take one sheng warm. If vomiting occurs, stop taking it; the disease will heal. Avoid consuming seaweed and Brassica vegetables.
Another formula for treating Pin Malaria: Shu Qi San.
Shu Qi (Washed to remove fishy odor) Yun Mu (Muscovite) Long Gu (Fossilized Bone)
The above three herbs are equal parts, pounded and sifted into powder. Take half a qian mixed with clear sour grain water one meal's time before the attack. Take another qian just before the onset. For Warm Malaria, add half a fen of Shu Qi and burn Yun Mu with charcoal over three days and nights before use. (Yun Mu is alternatively recorded as Yun Shi; all from Volume 15)
