Those doctors who say that electric kettles can't be decocted are of the opinion that electric kettles are decocted with big fire, no, sand pots are decocted with small fire, right. Haven't they studied physics? I don't know the boiling point of water. Is the small fire 100℃? It's not that boiling water is hotter than slow boiling water! As far as I know. When the substance of traditional Chinese medicine enters the water, the boiling point will rise a little, which is estimated to rise by 0.5℃ to 3℃. Are all the doctors in Doctor Thumb failing physics?
