Bruises on the tongue, which may have been accidentally scratched while eating, are not significantly painful until they solidify and can be left untreated. If there is significant pain or an ulcer, the mouth can be rinsed with mouthwash. It can also be caused by poor circulation, and then by improper stimulation. Chinese medicine considers it to be a manifestation caused by blood stasis, treated by activating blood circulation and removing blood stasis, herbal medicine such as Dan Shen or Blood Mansions and Stasis Capsules, together with Panax notoginseng tablets, etc. Avoid stimulation by cold, and if necessary, do further examination.
