How do you heal inflamed esophagus naturally or with home remedies?

How has thin inflammation been diagnosed/proven? Only endoscopy can do that.

If really inflamed, it usually is due to acid reflux from the stomach going up into your esophagus, thus you need meds to block acid production like Histamin2 blocker like ranitidine, famotidine, or protonpump inhibitors like omeprazole, esomeprazole, pantoprazole.

You get try to support these meds by following an anti reflux diet by not eating too much at a time, not eat fatty food, not smoke (stimulates the stomach to make more acid and weaken the circular sphincter muscle between stomach and lower esophagus that prevent reflux) tomatoes, citrus fruits, mint, not eat the last 2 hours before going to sleep, prevent constipation, and sleep on your left side and/or with the head of the bed elevated by 6 to 8 inches.
