Take the medicine juice and mix it with hot water of 40-50 degrees, and start to soak your feet until you sweat slightly. Be careful not to soak in sweat, or you will be very weak. It doesn't matter if you don't sweat, which is related to your physical fitness. Stick to soaking for a while and it will get better.
A good decoction can be soaked for 2-3 times. Put it in the container. There is no need to cook every day.
