Folks also use smoke to treat sores and ulcers, embodying the medicinal wisdom of "fighting poison with poison".

Modern research shows that in dry paintUrushiol, laccaseand other ingredients have significant biological activity. Experimental data shows that urushiol has an inhibitory effect on common pathogenic bacteria such as Staphylococcus aureus and Escherichia coli (see table below). In addition, its antioxidant capacity can scavenge free radicals and delay cell aging. Animal experiments also found that an appropriate amount of dry paint extract can reduce the release of inflammatory factors, verifying the scientific validity of the traditional "swelling" effect.
