People usually think that the Chinese medicine plant is the older the more effective, and mugwort is the universal use of medicinal herbs, then mugwort is not the more aged the better? The more you age, the better it is?

Isn't the older the better

There is no such requirement for medicinal moxa leaves. But the moxa leaves used in acupuncture and moxibustion have this requirement. Needles are used to puncture acupuncture points, and moxibustion is used to burn or roast moxa leaves and then used to smoke or burn the acupuncture points.

Then why in the end the more aged the better (generally considered not moldy can be), think with the combustion reaction of moxa leaves have a lot to do with the generation.

So the ancients were very careful, that is, moxibustion with moxa leaves, generally the more aged the better, so there are "seven years of disease, seeking three years of moxa" ("Mencius").

Mugwort is the better the older the better

Mugwort is also a kind of traditional Chinese medicine, also has a shelf life. Only now many merchants say the longer the better is a kind of gimmick. I think three years of aged mugwort is already the limit. If it is left longer, it will not have the flavor and efficacy of mugwort.

If you buy more moxa and leave it for 2-3 years I think it is still usable, if you leave it for too long, it is hard to say. It can be said that my family's moxa minimum is placed more than a year.

Because it is the manufacturer bought a lot of aged moxa leaves saved for processing, which is the minimum requirement for me to process moxa.

My family's I can only say, you can be placed about 3 years, if placed too long, maybe will lose a lot of features we do not think. What I said, just represent my own opinion.
