Hello, My father is suffering from last 2 yrs with oral lichen planus we tried lots of medicines, we changed doctors. we treated from Ayurvedic, Homeopathic, Allopathic but result is zero. Like he can't eat spciy food, hot, flavoured & hard(apple) food. I don't know what should i do. Can u give some Home remedies which i can try. I don't know how much that is affected but i don't want to take a chance. I want to try that thing. Plz suggest me what should i do. My father is really fed up now with medicines.
