Reasonable and scientific moxibustion itself is very effective, just stick to moxibustion. I bought this one, but the air inside is too small, the ventilation is slow, the moxa stick is easy to go out and burns slowly. I just like to use it on the soles of my feet, that is, to remove or lift the cover, which has let more air in. Now there is a small moxibustion pot made of wood, which is tens of dollars cheaper than this one. It's so good that I can't put it down. Moxibustion itself is very good. I have several years of experience in moxibustion, and my body has undergone many changes, which has given me many surprises. If you want moxibustion, moxibustion is moxa sticks. I want to buy something reliable. I have gone through many detours before, and I hope to adopt them.
