If you have accidentally swallowed some excreta of rats, some rotten material caused you skin allergy, your breath filled with stinking air, its not surprising that you are bound to get these problems. To my own patients I would say to clean your guts. First induce vomiting by drinking warm water with much salt 2-3 glasses at least. Put two fingers in throat and try to vomit. This should be tried empty stomach. Then induce purgation by mild herbal powder Tarunikusumakar chooran. If not available take Triphala capsules 2 caps thrice day for two days. You may feel weakness but no problem. Then follow max normal water to avoid dehydration with ORS. Take light food like rice n lentils boiled together for 2 days. You will be alright. In future follow clean lifestyle even in elated hrs. Hope it helps you.
