The length of time to use Rejuvenate to promote wound healing is usually related to the size of the patient’s wound, whether local infection occurs and other factors, and cannot be generalized. Kangfu Xin Liquid is a worm preparation with a wide range of clinical applications, which can be used in internal medicine and also in surgery. The main function of this drug is to promote blood circulation, nourish yin and produce muscle, which can promote the growth of granulation tissue, accelerate the shedding of necrotic tissue, rapidly repair all kinds of ulcers and wounds, and improve the immune function of the body. If the patient’s wound is small, local infection does not occur, and the patient recovers well, usually the use of this medicine can be effective in about 1 week, and recovery can be made in about 10 days. If the wound is large and local infection occurs, the patient usually needs to continue to use it externally under the guidance of a surgeon for about 1 month before the wound can recover. For patients with other chronic diseases, such as diabetic lower extremity gangrene and decubitus ulcers, the recovery of the wound is slower and the primary disease should be actively treated. In addition, during the recovery period, patients are advised to pay attention to increase nutrition, ensure balanced nutrition, and avoid spicy and stimulating food to promote tissue repair.
