Plaster Improvement

According to modern pharmacological research, black plaster is better than rubber plaster in terms of absorption and curative effect. However, due to the complicated production process of black plasters, there is no uniform standard, and it is difficult to carry out quality control, resulting in uneven quality of black plasters. Because the production of black plaster is time-consuming and laborious, Chinese medicine hospitals often carry out external application of Chinese medicine, that is, crushed by Chinese herbal medicines, mixed with honey, petrolatum and other bases in ointment form, and fixed with tissue paper and bandages. The dressing is changed every 24 hours, and the cost of use is higher. . Each black plaster can be used for 3-15 days, and it can be applied again after it is removed without affecting the curative effect, so the cost is lower.
