Take pure and clear pine rosin (Pinus massoniana resin), the amount is unrestricted. Melt it and remove impurities, use river water, place in a clean pot, boil the pine rosin until melted, stirring constantly. Observe when the water color becomes turbid like rice washing water, and tastes extremely bitter, immediately pour into cold water. While hot, pull and stretch the pine rosin. Once cooled and hardened, replace with fresh water to boil again, then pull again. Repeat this process as many times as necessary, regardless of dozens of times, until the pine rosin body is loose, white, and jade-like, and the boiled water is no longer bitter. Dry it in the shade, grind into powder, sieve to an extremely fine consistency, reserve two jin (approx. 1 kg). During treatment, consume only white porridge daily. Mix an appropriate amount of the medicinal powder evenly into the porridge and eat it. Do not chew excessively; take several doses per day. Strictly avoid dry rice; only allow dried vegetables and dried bamboo shoots to pass through the mouth. All oily, salty, soy sauce, vinegar, meat, fish, alcohol, fruits, sugar, and wheat products are strictly prohibited. When thirsty, drink only boiled plain water. Take three to four qian (approx. 9-12 g) of powder daily, increasing gradually, do not increase too rapidly. After taking the medicine, toxic matter will be excreted in the stool. Upon finishing one dose, self-healing occurs.
