If you have a bad cold, it is economical and effective to soak your feet with boiling water of Artemisia argyi and safflower before going to bed at night, and there are no side effects. It can be soaked all year round, which is a radical method for promoting blood circulation and nourishing yin and yang. However, it is not advisable to soak your feet with mugwort safflower every day. You can soak your feet in boiling water for three days at first, and then soak your feet with mugwort twice a week. At other times, just soak your feet in hot water. The water temperature is about 40 degrees, so you can soak for 30 minutes or sweat slightly. In addition, if conditions permit, moxibustion box can also be used for moxibustion. Moxibustion is mild and safe, even for pregnant women. Both foot bath and moxibustion are suitable for cold constitution and can be used for a long time. My body is cold and wet, my stomach is weak and my blood pressure is low. The doctor advised me to soak my feet every night. Now I'm not so afraid of cold, and my hands and feet are not so easy to catch cold. I have been trying moxibustion recently, and the effect is good. This is my personal experience, please adopt it ~
