Ingredient of moxibustion
In order to produce good moxa, the quality and quantity of the soft fuzz (composed trichome and glandular hair) which grows on the underside of Japanese mugwort is of particular importance.
Within this fuzz, particularly within the glandular hairs, is a volatile oil (eucalyptol = insecticide, tannic acid = antipyretic, terpene = scent) which is the active ingredient. It is said that domestic Japanese mugwort contains twice as much of this oil as other types of mugwort.
The higher the ratio of these glandular hairs, the better the fire that is produced. (This means that the moxa catches fire easily and burns out in a flash.) This creates a first-rate moxa in which no heat is felt.
On the other hand, trichomes create a soft and sticky moxa with good spread and high efficiency.
There are a variety of other requirements for the quality of raw mugwort which can create large differences in the moxa it produces. Good moxa produces only a small amount of ash (high-grade domestic moxa produces 3-4%) and contains a moderate amount of moisture (high-grade domestic moxa contains 11%). Other factors are the medical properties of the moxa, such as its effectiveness in sterilizing skin and the disinfection which is provided when smoke from the burning moxa drives away noxious gases, and its tranquilizing efficiency.
Because high-grade domestic moxa is made using the best manufacturing techniques and climate, it is easy to light and permeable with no feeling of heat. On top of that, it also has a wonderful fragrance, produces elegant smoke, and provides refreshment and equilibrium to both body and soul.
We believe that ibuki moxa made from this high-grade moxa allows for the best moxa experience.
