The harm of moxibustion is generally not related to age, but generally related to a person’s constitution, disease evidence, etc. If the patient belongs to the Yin deficiency constitution or belongs to the Kidney Yin deficiency and fire (deficiency of Yin and essence in the body, the emergence of deficiency and fire exuberance) evidence, etc., moxibustion may aggravate the discomfort. People with yin deficiency tend to eat and drink cold foods, have dry mouth and throat, and sweat easily when they fall asleep; and kidney yin deficiency and hyperactivity of fire are common symptoms such as lumbago, tinnitus, hot flashes (bursts of heat), and zygomatic redness (reddening of the cheeks and zygomatic bone area). If inappropriate moxibustion is applied to the above conditions, it can aggravate the discomfort. However, moxibustion treatment is more appropriate for patients with yang-deficient bodies and deficiency-cold disorders. If a 70 year old person needs moxibustion, it is recommended to visit a professional medical institution and be evaluated by a doctor before deciding whether to use moxibustion therapy.
