Mugwort ash actually cannot help cure athlete's foot, but if you soak your feet in mugwort ash or mugwort over a long period of time, it can significantly help improve the condition. This is because soaking in hot water accelerates local metabolism and promotes blood circulation, thereby effectively relieving and improving the condition. Mugwort itself can achieve the purpose of relieving itchiness and dispelling dampness, which can significantly help in conditioning the body and providing relief. For cases of athlete's foot, it is necessary to manage it through regular physical exercise or daily foot soaks.
