This moxibustion barrel is made of either iron or copper about 2 ～ 5mm in thickness and consists of an inner and outer barrel. There are holes at the bottoms and on the walls of the inner and outer barrels. There isalso a removable lid which fit in the outer barrel. A stand affixed to the inner barrel keeps a distance with the outer barrel and a handle on the outer barrel is convenient for holding. Fill the moxa floss in the inner barrel and light it then place the inner barrel into the outer one and cover with the lid (Figure C4).
