Aloe vera should not be used directly to rub wounds, especially traumatic and open wounds, which may cause allergies, edema of the affected area, infection and other adverse reactions. Although aloe vera has a certain medicinal value, with a certain anti-inflammatory, disinfectant effect, but the daily life of aloe vera is a mixture of ingredients, and there is no purification process. Therefore, if you abuse aloe vera and apply it to open wounds, it is likely to cause irritation to the mucous membranes of the skin at the wounds, causing edema, infection and even allergy in the affected area. If the skin does not have an open wound, you can consider applying aloe vera to help with swelling as well as inflammation. For open wounds, it is best to seek medical attention and disinfect and medicate the wound in a timely manner.
