The general method of soaking feet with Folium Artemisiae Argyi is: take 50g of Folium Artemisiae Argyi (one handful is enough), add water to the pot, boil the water for 10 minutes, turn off the fire, pour it into the basin, and wait for the water to naturally cool to a temperature that the feet can adapt to. Soak until the whole body is slightly sweaty, and the foot bath is over. Then massage Yongquan point 50- 100 times, and then undress and rest. .
