Plaster making skills (Jiang's bone injury plaster making skills, Qiu's burn plaster making, Xuzhou decomposing and regenerating plaster medicine, Wu's plaster) have been expanded to Lianshui County, Xinghua City, Xuzhou City, and Tinghu District, Yancheng City. Jiang's bone injury plaster making skills were created in the 16th year of Guangxu in the Qing Dynasty. Jiang Yucheng from Andong (now Huai'an Lianshui) combined his years of learning, combined the strengths of hundreds of schools, and devoted himself to research. He created a unique bone injury plaster making skill, which combines manual bone correction with plaster external application to treat bone injuries. After five generations, the making skills have been continuously passed down and are now mainly popular in Lianshui County and surrounding areas. Jiang's bone injury plaster is a traditional black plaster for external application, specializing in the treatment of injuries from falls. The making skills are strictly made according to the selection of materials, 0, refining, making dan, collecting ointment, soaking, spreading and other processes. It is made of more than 20 kinds of authentic medicinal materials such as Sanguisorba officinalis, Strychnos nux vomica, Myrrh, Frankincense, Asarum, Eupolyphaga sinensis, Panax notoginseng, Angelica sinensis, Borneol, Salvia miltiorrhiza, and Guangdan. The main production process is: put Strychnos nux vomica in an oil pan and fry it until the color turns brown and black, then put the medicinal materials except Sanguisorba officinalis, Guangdan, Myrrh, Frankincense, and Borneol into the oil pan and fry until the medicinal materials are dry, filter out the medicinal residues, and keep the medicinal oil. Refining: Put the medicinal oil in an iron pan, and then refine it with a low fire. At the same time, use a spoon to slowly stir the oil, and emit thick smoke until the smoke turns white and turns dark. Dip a little medicinal oil, drip water into beads, and blow it without dispersing. Add the finely sieved Guangdan slowly into the medicinal oil, stir with wet locust tree strips, so that the medicinal oil and Guangdan are fully synthesized into a black paste. Then slowly add the finely crushed myrrh, frankincense, Sanguisorba officinalis and stir continuously, and finally add the borneol. When collecting the ointment, spray cold water into the ointment to make the smoke go out and solidify into an ointment. After soaking, soak the ointment in cold water for 8-10 days. After changing the water 1-2 times a day, take the ointment out of the water, heat it to dissolve it, spread it on kraft paper or cotton cloth, and store it for later use. It needs to be heated to make it sticky before use. The production technique of Jiang's bone injury plaster has existed for more than 100 years. It has a unique formula, excellent formula, and exquisite craftsmanship. The efficacy enters the body through the pores of the skin and is conducted through the meridians. It can remove blood stasis, generate new blood, cool blood, stop bleeding, open joints, reduce swelling, relieve pain, regenerate muscles, and connect tendons and bones. The effect is very significant. The production technique of Jiang's bone injury plaster condenses the experience and wisdom of the Jiang family in traditional Chinese medicine bone injury treatment. It has been passed down from generation to generation without interruption. It has a certain reference value for studying bone injury treatment methods and medicines.
