Mugwort leaves and moxa velvet are the same kind of traditional Chinese medicine, and there is no obvious difference in their medicinal effects. Mugwort leaves can be taken internally or used externally, while moxa velvet is made into moxa sticks or cones for external moxibustion. Ai velvet is crushed and sifted into a fine, soft, cotton-like material, lit moxibustion. Mugwort is flammable and should be kept in a cool, dry place to avoid fire. Mugwort leaves can be decocted and taken internally, or used externally, pounded, decocted and smoked, or fried and warmed. Both moxa leaves and moxa floss are warm herbs, both have the effect of warming the menstruation and stopping bleeding (warming the human body’s meridians to stop bleeding in the body), dispersing cold and relieving pain (relieving pain by removing cold from the body). Mugwort is warm, slightly toxic, and should not be used with caution in people with abnormal liver or kidney function, and should not be overdosed for too long, and should not be used in patients with yin deficiency or fever. Patients who are not feeling well are advised to consult a doctor in time and should not use the medicine on their own to avoid delaying their condition.
