Gastritis Support Group
Gastritis is a medical term for inflammation of the lining of the stomach. It means that white blood cells move into the wall of the stomach as a response to some type of injury. Gastritis has many underlying causes, from infection with the bacterium H. pylori, bile reflux, or excessive consumption of alcohol or certain foods or drugs like aspirin.

In addition, consider taking Chlorella (Source Naturals Broken Cell Wall Chlorella). It protects and detoxifies the liver.
One side-effect: your poop will turn green. But it's harmless.
