It can be used to treat purulent infections of the skin and mucous membranes, stomatitis caused by Candida albicans, burns and scalds, and can be applied topically to the skin and mucous membranes two to three times a day. The main adverse effects of methyl violet solution are that it is slightly irritating to the mucous membrane of the skin and may cause contact dermatitis, while it should be used with caution if there is a history of ulcers. The main concern about the application of methyl violet solution is that some studies have shown that methyl violet solution is a dose-related carcinogen, and when used for a long time or in large doses, it may cause genetic mutations in humans, which may eventually lead to cancer in humans. Therefore, do not use methyl violet solution over a large area, and try to use it sparingly in areas where there is a break in the mouth. Methyl violet solution can corrode the mouth, but try not to have a break in the mouth, do not have ulcers, such a wipe is no problem, or relatively safe and reliable.
