We have a close friend who has a rash on his tongue, less a rash more like an wound, very red and sore on the surface of the tongue very difficult to eat, had it for a long time now. He has tried everything, hospital laser burn off. Chinese medicine and Ayurveda medicine both say he has high heat in him , he has taken Brahmi and ground coriander and cardamom amongst lots of other indian remedies to reduce the inner heat but condition (Lichen Planus) not gone away.
