Aloe vera is a commonly used herbal medicine in clinical practice, and generally plays a role in clearing heat and detoxifying. However, some patients think that the direct application of fresh aloe vera, applied to the wound can play the role of antiseptic and anti-inflammatory, to promote wound healing. In fact, this idea is not correct, generally speaking, to promote wound healing drugs in the clinic, it is recommended to apply recombinant human epidermal growth factor or the like. Fresh aloe vera contains some ingredients with obvious irritating effects, and applying fresh aloe vera directly to the wound may cause severe irritation to the wound, and the patient will feel severe pain. If applied repeatedly, it can affect the surrounding healthy tissues as well as the more delicate and healing tissues. It may also cause some allergic irritation to the skin, which may lead to secondary infection.
