Zaofan (Green Vitriol), also known as Qingfan, is called Fanhong when red in color.
It is incompatible with Vinegar (Cu).
Acidic and cool in nature. It resolves accumulation and stagnation, and dries Spleen dampness. It treats Hou Bi (sore throat/obstruction of the throat), Kou Gan (oral ulcers/gangrene), Chong Ya (worm-induced toothache), E Chuang Jie Xuan (malignant sores and scabies/tinea). When combined with Pingwei San (Calm the Stomach Powder), it treats Huang Dan (jaundice). When combined with Hong Qu (Red Yeast Rice) and Shan Zha (Hawthorn Fruit), it resolves meat accumulation. When combined with Da Zao (Jujube), remove the pits, fill with Zaofan, calcine, grind into powder, and apply externally to children's Tian Chuang (sweet sore/moist eczema) and rotten sores in the ear.
Mix with Vinegar and store in a porcelain bottle. Overuse is harmful. Those taking this medicine must avoid Buckwheat for life.
Ancients often mistakenly identified Qingfan as Danfan (Blue Vitriol). This is incorrect.
This refers to Shidan (Stone Gall).
Shui Ying (Hydrophyllum Japonicum) serves as its guiding herb (Shi Yao). It is incompatible with Jun Gui (Cinnamon Bark from specific trees), Yuan Hua (Genkwa Flos), Xin Yi (Magnolia Flower), and Bai Wei (Cynanchum Atratum Root).
Pungent and acidic, cold in nature. Toxic. Enters the Foot-Shaoyang Gallbladder Meridian. It induces vomiting to expel wind-heat phlegm-saliva, and disperses wind-liver and ministerial fire. It kills parasites and reduces carbuncles, treating sores of the throat, mouth, and teeth. Combined with Vinegar, instill into the ear to kill insects.
(Gargle to spit out phlegm-saliva; immediate effect for Hou Bi.) Combined with Honey and applied topically, it treats swelling and pain of various hemorrhoids. Paired with Long Dan Cao (Gentian Root), calcined until smoke ceases and turns red to remove fire qi, ground into fine powder, and applied externally to severe cases of Zou Ma Ya Gan (noma gangrenous stomatitis), yielding miraculous effects.
Paired with Chao Bai Jiang Can (Stir-fried Bombyx Batryticatus), ground and insufflated into the throat to treat Hou Bi throat qi. Placed inside Hei Zao (Black Jujube), calcined and ground, applied to Ya Gan (gum gangrene).
Apply on copper or iron and burn; those that turn red are genuine. Those bright like emerald glass, resembling the color of a duck's bill, are of superior quality.
(50 kinds of Mountain Herbs)
Bai Zhu (Atractylodes Macrocephala Rhizome), Ku Shen (Sophora Flavescens Root), and Gan Xi (Dry Larch Resin) serve as its guiding herbs (Shi Yao). It is repelled by Yuan Zhi (Polygala Root). It is chemically incompatible with Da Ji (Euphorbia Pekinensis Root), Yuan Hua (Genkwa Flos), Gan Sui (Kansui Root), and Hai Zao (Sargassum Thallus). Avoid eating pork.
Sweet in taste. Enters the Qi aspect of the Hand-Shaoyin Heart Meridian, Foot-Yangming Stomach Meridian, Foot-Taiyin Spleen Meridian, and Foot-Jueyin Liver Meridian. It benefits essence, nourishes qi, clears heat, harmonizes the middle, strengthens the Spleen and Stomach, resolves all toxins, harmonizes collateral blood, relieves liver tension, dispels pathogenic heat, strengthens bones and tendons, promotes muscle growth, and treats toxin sores. Combined with Zhu Dan Zhi (Porcine Bile), calcined into powder, mixed with Mi Tan (Rice Wash Water), and administered orally, it treats infants under one month old with Man Gan Feng (Slow Liver Wind), characterized by eyes closed and unable to open, swollen and photophobic, or bleeding. Combined with Jie Geng (Platycodon Root), it clears the throat. Paired with Da Dou Zhi (Soybean Juice), it resolves the toxicity of all medicines, with remarkable efficacy.
It assists in warming and dispersing blood stasis. Added to moistening agents, it nourishes Yin blood. Added to pungent-cool formulas, it moves turbid blood in the Liver and Stomach. (The head portion is preferred.)
Those that are large, tightly knotted, and have clear fracture lines are considered excellent, called Fen Cao (Powder Licorice). Raw use clears Heart fire, defeats fire toxins, relieves Kidney tension, and harmonizes collateral blood. The tip (Shao) stops pain in the urethra/stem and removes heat from the chest. The nodes (Jie) reduce swelling and detoxify. Honey-fried or stir-fried with Jing Mi (Brown Rice) harmonizes the middle and tonifies the Spleen and Stomach. Contraindicated for wine drinkers, those vomiting, early-stage alcohol-dysentery, and those with fullness in the middle jiao.
