Mugwort leaves have very good effect of warming and dispersing cold, invigorating blood circulation and relieving menstrual pain. If mugwort leaves are applied directly to the affected area, it is difficult to be absorbed directly through the skin, and the therapeutic effect is quite slow. If mugwort leaves are applied to the affected area of the knee, to achieve the effect of dispelling wind and removing paralysis and invigorating the blood, mugwort leaves are decocted and then applied directly to the affected area with a hot towel to invigorate the blood through the nature of warmth. This can improve a series of complications such as pain in the knee joints and poor mobility. You can also make moxa leaves into moxa wool, or moxa pillars, which can be lit and smoked to local acupuncture points and local pressure points, which is equivalent to moxibustion treatment in Chinese medicine, and can have a very good effect of invigorating the blood and activating the meridians.
