The water of mugwort leaves just boiled is rather hot. Some people say that it is not easy to cool with a lid. Can you leave the lid on?
We can definitely answer: no. If the lid is not covered, the effective components in the medicine will evaporate with water vapor, which will affect the curative effect.

Experts in relevant fields said that soaking feet with mugwort leaves without sweating is a personal physical problem, and it will be fine if you persist for a while, and you don't have to sweat.
