Is it safe to use tiger balm every day? The only active ingredients are camphor and menthol.

Why? What's going on? Are you congested? Do you just want to use it when you are sick, or forever? Please ask again and clarify. It is pretty harmless, but your symptoms may be something that Tiger Balm won't help or it may aggravate whatever is going on.
Tiger balm can be. used every day. It does not have any ingredients with long lasting effects. Though you shouldn't use it in the eyes or any mucosal surface like inside the nostrils or mouth. Thanks for trusting in HealthTap.
