Moxibustion involves the burning of the moxa herb 艾 on or near the skin. Depending on how moxa is used and prepared, moxibustion can increase either the Yin or the Yang energy within the body. For example, because it is hot ( Yang ) then the resulting cooling effect ( Yin ) will be increased ( like sweating- which cools the body ). We can think about general inflammation/ fever etc. Applying heat to inflammation / tight areas encourages the bodies own defensive mechanism to come into play and thus reduce/ stabilise inflammation or tightness. Moxa is particularly beneficial for people with chronic low-grade systemic inflammation or compromised immune systems. It can also significantly reduce painful swelling caused by trauma from sports injuries/ post-operative surgery.
