What are the functions of Hedyotis diffusa, Scutellaria barbata and Hedyotis diffusa together?

All three herbs have the effects of clearing away heat and toxic materials, promoting diuresis and reducing swelling, among which Hedyotis diffusa also has the effect of eliminating carbuncle and resisting cancer, and is mostly used for gastric cancer. This prescription is suitable for the long summer when damp heat and poison are abundant. It can not only clear away heat, but also eliminate dampness, and has the wonderful effect of preventing moisture and suppressing heat, thus completely removing heat. When drinking, if you see a light mouth, bloating or diarrhea, you should stop, which is a sign of overdose.
