Generally speaking, the amount of moxa will vary according to the different treated areas, diseases and patient’s constitution.
For example, a small amount of moxa is suggested on areas such as the head, face, chest and the end of the extremities since the skin is thin and there are more bones and fewer muscles. On the other hand, a large amount of moxa is suggested on the waist, abdomen, shoulders, and thighs, where both the skin and muscles are thick.
The disease situation also has to do with the amount of moxa used in the treatment. For example, a large amount of moxa is effective on obstinately cold disease and yang qi depletion. On the other hand, a small amount of moxa is used for cold diseases, carbuncle, gangrene, numbness and pain.
The patient’s constitution is another consideration. The stronger patient sustains more amount of moxa during the treatment. For weak, senior, or very young patients, a smaller amount is used in treatment.
