Watermelon cream can be sprayed on some wounds because it contains watermelon cream, cypress, cyperus and ice chips, which can be used for mouth ulcers, gingivitis, stomatitis and other diseases. However, if the wound is caused by trauma or is localized after surgery, the drug should not be used, which will lead to local infection and slow healing of the wound, and can easily lead to local scarring. The wound must be disposed of in the hospital’s surgery or emergency department, where the doctor will generally use iodine volts for disinfection and, if necessary, iodine, then debridement and suturing according to the condition, and later oral antibiotics or infusions may be required. Therefore, once there is a wound, do not self-medicate, and should be treated under the guidance of a doctor to prevent local aggravation and delay in treatment. During the treatment period, the wound should be kept away from water as much as possible and activities should be reduced as much as possible, which can promote the healing of the wound.
