[Xie Bai San (Drain the White Powder)] (From Qian Yi) Treats Lung Fire, manifesting as steaming heat in the skin. (The Lung governs the skin and hair; a pulse felt lightly but disappearing with heavy pressure indicates heat in the skin and hair.) Chills and fever alternating. (Pathogenic factors are in the skin and interstices.) Symptoms worsen at dusk (Shen and You hours, 3 PM–7 PM, when Metal energy is strongest). Asthma, cough, and rapid breathing. (The Lung suffers from rebellious Qi.)
Ingredients: Sang Bai Pi (Mori Cortex), Di Gu Pi (Lycii Cortex) (each 1 qian), Gan Cao (Glycyrrhizae Radix et Rhizoma) (0.5 qian), Jing Mi (Oryzae Fructus Glutinosa) (100 grains).
Analysis: Sang Bai Pi is sweet, pungent, and cold; it promotes water metabolism, descends fire, and drains excess Qi from the Lung. It eliminates phlegm, stops cough, benefits urination and defecation, and treats thirst due to heat. Di Gu Pi is cold and drains heat from the fire level.
If Ren Shen (Radix Ginseng), Wu Wei Zi (Schisandrae Fructus), Fu Ling (Poria), Qing Pi (Aurantii Fructus Immaturus), and Chen Pi (Aurantii Pericarpium) are added, it is named Jia Jian Xie Bai San (Modified Drain the White Powder).
