Jiang's ancestral bone injury plaster making skills are a traditional medicine project in the fifth batch of representative projects of Huai'an's municipal intangible cultural heritage. 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 skills, 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 treating 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 blood clotting, strychnine, beehive, myrrh, frankincense, asarum, earthworm, Panax notoginseng, angelica, borneol, salvia miltiorrhiza, and Guangdan. The main production process is: put the strychnine into the oil pan and fry it until the color changes to brown and black, then take it out, and 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 residue, and keep the medicinal oil. Refining: put the medicinal oil into the iron pan, and then refine it with a low fire, and slowly stir the oil with a spoon, and emit thick smoke until the smoke turns white and 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, and Sanguisorba officinalis in turn and stir continuously, and finally add borneol. When collecting the paste, spray cold water into the plaster to make the thick smoke go out and solidify into a paste. 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 formulation, 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, and has a certain reference value for studying bone injury treatment methods and medicines.
