The lack of suction of fire canning may be due to too little fire, too slow buckling of the can, the application of the site of the muscle is not rich and so on.
1. The fire is too small: the amount of alcohol may be too small, or the cotton ball is too small, resulting in insufficient burning fire, can not be fully burned to eliminate the air in the jar.
2. Buckling too slow: cupping action should be light, fast, accurate and stable, buckling too slow is likely to lead to a drop in the temperature of the can, the air re-entry cans, so that the adsorption of the cans become smaller.
3. Cupping site is not rich in muscle: the cupping site should be chosen to be more rich in muscle, less hair or subcutaneous tissue is more full of places, so that the can is easier to adsorb, if the choice of knees, shoulders and other muscle is not rich in places, the can is not easy to adsorb.
It is recommended that fire cupping operation be carried out by a professional Chinese medicine technician, not by yourself to avoid adverse consequences.
