Ai cones are cones made of moxa floss by hand or with a utensil, and the cones are placed on the acupuncture points or lesions, and then lit to apply moxibustion, which is known as moxibustion, and moxibustion is divided into two categories: direct moxibustion and indirect moxibustion. 1. direct moxibustion, also known as skin moxibustion, is to put the moxa cones directly on the application of parts of the lighter to ignite the incense, and then ignite the moxa cones for moxibustion, so as not to burn the skin. When the moxa cones are completely burned out, the skin will be burned and pus, and there will be scarring after the healing process, which is called scar moxibustion. In the process of moxibustion, do not burn out the cones, burning until the skin appears flushed without burning pain is appropriate, known as scarless moxibustion. 2. Indirect moxibustion refers to the method of moxibustion between the cones of moxa and the skin of the application site separated by specific drugs or other materials. The drugs or other materials needed to be used for the separation are determined by the doctor after the identification of the disease. Clinically, there are ginger moxibustion, garlic moxibustion, salt moxibustion, and epiphyllum cake moxibustion. Moxibustion needs to be operated by a doctor, please do not operate on your own to avoid improper operation, which may lead to adverse consequences.
