Mustard powder mixed with white vinegar is a folk prescription for treating hyperosteogeny.

The specific method is:

Take a proper amount of 9-degree rice vinegar and a proper amount of mustard to cook. The amount of raw materials depends on the size of the affected area. Mix mustard and rice vinegar and apply it to the affected area with a thickness of about 3 mm, and keep it moist after application. If it is dry, you can drop some vinegar or wrap it tightly in plastic until it is good.
