Zhang's bone-setting plaster making technique is a traditional medicine project in the fourth batch of representative projects of Yancheng's municipal intangible cultural heritage. Zhang's bone-setting plaster has been passed down for six generations, with a history of more than 200 years. It was first created by Zhang Xiangrui, who founded the "Xiangruitang" pharmacy in Shanghai. According to the "Zhang's Secret Book", his bone-setting skills were taught by his uncle, a famous bone-setting doctor at the time. The "Secret Book" records various bone-setting techniques, bone-setting plasters, analgesic and stasis-removing plasters, rheumatism plasters and other plaster formula making methods, and has been continuously used clinically with obvious and unique effects. It was passed down to the sixth generation Zhang Zikun. Because of his exquisite bone-setting skills and unique effects of family-inherited plasters, he continued to study Chinese herbal medicines diligently. On the basis of ancestral plasters, he continuously improved and integrated the plaster making methods, continuously optimized according to clinical efficacy, combined with the pathological characteristics of patients, and continuously optimized, and achieved significant therapeutic effects. Drug composition: Angelica, Zelan, Danshen, Panax notoginseng, frankincense, myrrh, Corydalis, peach kernel, Sappan wood, Gardenia, Platycladus orientalis, peony, Phellodendron, Scutellaria, Raw Chuanwu, -, Drynaria, Raw Bitter Beans, Dipsacus, Cucumber seeds, mulberry branches, etc. Drug preparation method: 1. Drug preparation: Grind each Chinese medicine into fine powder according to its own amount. Put "Angelica, Zelan, Danshen, Panax notoginseng, Phellodendron, Scutellaria", "Frankincense, myrrh, Corydalis, peach kernel, Sappan wood, Gardenia, Platycladus orientalis, Red Peony", "Raw Chuanwu, -", "Broken Bone, Bitter Beans, Dipsacus, Cucumber seeds, mulberry branches, and Natural Copper" in four different containers respectively. 2. Preparation of plaster: Stir-frying yellow dan: Put red dan in a clean copper pot, stir-fry over low heat until the water vapor in the dan is gone, and stir-fry with a shovel constantly; Refining oil: Put vegetable oil in another clean copper pot, boil it over high heat, and then change to low heat. At first, the gas of oil and water will rise straight up, and after a while, the gas will swirl up around the pot. Use bamboo chopsticks to drop oil on cold water. If it forms beads and does not disperse, the oil refining is complete; Fire and Dan: Continue to boil oil over low heat, slowly put the fried dan into the boiling oil, and stir it clockwise with a willow stick. The oil will overflow and emit bubbles and thick smoke. When the smoke is slightly gone, use bamboo chopsticks to drop three or four drops of oil on cold water. If it forms beads and does not disperse, try to pinch it with dry hands. It is not greasy when it sticks to your hands and leaves your hands. 3. Remove fire poison: After the plaster is made, spray it with cold water in the plaster pot, and black smoke will come out. Then twist the plaster into small pieces and soak it in cold water for 7 days, changing the water every day. 4. Change the plaster: Put the plaster ball in a copper pot, melt it on the fire, use bamboo chopsticks to pick up a certain amount of plaster and put it on the cloth, pour the appropriate amount of fine powder of medicine in four containers on the plaster, according to the size of the cloth, use bamboo chopsticks to touch the center of the cloth, and spread it clockwise for a week, then the plaster is ready. Treatment method: Accurate reduction and firm fixation are the basis. Oral decoction and external plaster are used together. Oral decoction advocates three-stage medication according to the fracture stage: activation, breaking, and supplementation. In the early stage, "breaking" is the main method, breaking stasis, promoting qi, clearing heat and detoxification, and relieving pain. In the middle stage, "activation" is the main method, activating blood circulation and unblocking collaterals. In the late stage, supplementation is the main method: replenishing the liver and kidney, qi and blood, and strengthening bones. The proportion of external plasters and Chinese medicine used should be adjusted according to the fracture stage. Efficacy and indications: Indications of various types of closed fractures: removing stasis, relieving pain, and promoting fracture healing. It has the effect of significantly shortening the course of fracture. Usage: Apply the plaster flatly to the fracture site and change it every seven days until the fracture heals. Note: Patients with allergies should use with caution. If mild itching or stinging occurs on the plaster, remove it immediately and continue using it after the itching subsides.
