Astringent, dries dampness and transforms phlegm.
Acidic, salty, and cold in nature. Its property is astringent and contracting. It dries dampness and expels saliva, resolves phlegm and turbidity, detoxifies, dispels wind, and kills parasites. It stops bleeding and relieves pain, unblocks the large and small intestines/bladder.
[White Alum] Erodes foul flesh, generates good flesh, and clears stubborn heat from the bone marrow. (When the marrow is depleted by heat, it becomes empty, leading to bone flaccidity and floating teeth.) Treats fright epilepsy, jaundice, blood pain, throat obstruction, toothache, wind-eye, nasal polyps, uterine bleeding and leukorrhea, rectal prolapse, vaginal erosion, and vaginal prolapse. (Vaginal tissue protruding is due to fire in the Liver channel.) Treats carbuncles, sores, ulcers, scrofula, skin diseases, and bites from tigers, dogs, snakes, and insects. (Li Xun said: For any back carbuncle, one should take Wax Alum Pills to protect the membrane and prevent toxic vapors from attacking inward. Use 1 liang of White Alum and 7 qian of yellow wax, melt and mix into pills. Take 10 pills per dose, gradually increasing to 20 pills. Taking 100 pills daily makes the effect potent. This medicine greatly protects the membrane, pushes out toxins, detoxifies, and resolves pus. Li Shizhen said: It can induce vomiting of wind-heat phlegm-saliva, utilizing its sour-bitter purgative nature; treating various blood pains, vaginal prolapse, rectal prolapse, and sores/ulcers, utilizing its sour-astringent contracting nature; treating wind-eye, phlegm-fluids, diarrhea-dysentery, and bleeding-leukorrhea, utilizing its contracting and drying-dampness nature; treating throat obstruction, abdominal worms, and snakebites, utilizing its detoxifying nature. Crushing White Alum and bud tea into powder and taking with cold water solves all poisons.) Overconsumption damages the heart and lungs and injures the bones. (Su Song said: Because it repels water, writing on paper shows that water cannot wet it, thus knowing its nature repels water.) Select those that are white, bright, and lustrous for use. Raw use detoxifies; calcined use generates flesh. Another method: Heat the ground with fire, sprinkle water on it, spread alum on the ground, cover with a plate, surround with ash on four sides. After one day and night, the alum sublimates onto the plate. Sweep and collect it as "Alum Essence." The remaining part...
[Green Vitriol] Sour, purging, cooling, dispersing, astringent, contracting. Dries dampness and transforms phlegm, detoxifies and kills parasites, promotes urination, and reduces food stagnation. (Used with spleen-strengthening herbs.) Disperses throat obstruction. (Mixed with vinegar and swallowed as juice. Li Shizhen said: Many formulas for distension, yellow swelling, malaria, and dysentery use it extensively. Its origin changes from Zhang Zhongjing's formula using Alum Stone and Niter to treat female-labor jaundice.) Main indications are slightly similar to White Alum. Also known as Soap Alum. (Named so because it can dye black.) Deep green, bright, and clean ones are superior. Red-colored ones are called Crimson Alum. It enters the Blood level, subdues Liver Wood, and dries Spleen dampness. (Zhang Sanfeng's Immortal Transmission Formula records the Subdue Wood Pill: 2 jin of Atractylodes Macrocephala Rhizome, soaked in rice wash water; 4 liang of Yellow Rice Wine and Yeast, stir-fried; add 1 jin of Crimson Alum, mixed with vinegar, dried, placed in a bottle, calcined over fire into powder, mixed with vinegar into pills, taken with wine. Treats Liver Wood overacting on Spleen Earth causing epigastric fullness, or yellow swelling like earth color.)
