It is true that you can eat boils if you eat boils. Gallnut contains enzymes that can dissolve fat, which is a way to promote digestion and absorption by using its own enzymes and achieve the purpose of "eating gall". The experiment showed that compared with the control group, the weight and fat of mice fed with gallnut decreased obviously, which proved that gallnut could lose weight by decomposing fat. But it may also damage normal tissues, so use it with caution. Eating gallnut to lose weight has certain risks and needs to be carried out under the guidance of a doctor.
