Sweet, neutral. Enters the Qi level of the Heart Meridian of Hand-Shaoyin and the Liver Meridian of Foot-Jueyin. Reaches the Gate of Vitality (Mingmen), promotes urination. Disperses blood stasis, breaks up firm accumulations, calms the Spirit, and stabilizes the Soul. Combined with Cinnabar (Zhusha), it treats fetal fright (Taijing). Paired with Cinnabar (Zhusha) and Scorpion (Quanxie), it treats fetal epilepsy (Taixian). Assisted by Rhubarb (Dahuang) and Turtle Shell (Biejia), it purges evil blood (E-xue). With Allium macrostemon (Luchong), it treats dribbling dysuria (Linli).
The authentic product can attract mustard seeds when rubbed between the palms. Grind into powder, steep in boiling water, let cool until it congeals like a stone flower, then take with medicine. Contraindicated for those with Kidney deficiency causing difficult urination.
Bland, bitter. Enters the Kidney Meridian of Foot-Shaoyin and the Bladder Meridian of Foot-Taiyang. Removes mental restlessness caused by water-dampness in the Heart, distinguishes the yin-yang transition in malaria. (It can subdue Yin within Yang.) Contraindicated for dim vision and thirst without dampness. (Because it drains water.)
Wang Sun'an treated malaria by adding Polyporus (Zhu Ling) to decoctions. Since Yin and Yang contend above and below, causing alternating chills and fever, he used Cimicifuga (Shengma) and Bupleurum (Chaihu) to raise the Yang within Yin, and Anemarrhena (Zhimu) and Polyporus (Zhu Ling) to lower the Yin within Yang. Additionally, one dose of Polyporus (Zhu Ling) regulates the Upper Jiao and opens the interstices (Cou Li), allowing pathogenic factors to exit outwardly.
Magnolia bark (Houpo), Genkwa flower (Yuanhua), and Litchi seed (Lishi) act as guides. It is incompatible with Kudzu root (Gegen) and Knotweed herb (JiSun).
Bitter, cold. Slightly toxic. Enters the Large Intestine Meridian of Hand-Yangming and the Stomach Meridian of Foot-Yangming. Dries Spleen dampness, clears heat, eliminates accumulation, and kills parasites. (When damp-heat is removed, the habitat of parasites collapses naturally.) Soaked in Licorice juice, steamed with wine, or soaked before use. Those that are red in color cause death.
Strange symptoms: Worms growing in skin and flesh, moving like crabs, crying like infants; this is the transformation of muscle and flesh. Use Wanillospora (Leiwu) and Realgar (Xionghuang), each 1 liang, ground into powder, sprinkled on pork, roasted, and eaten.
Contraindicated with fire processing.
