Hi Thamm the other day I was feeling sick again and i searched on the internet about home remedies for gastritis and I found that the potato helps a lot, here is how you should do it, if you have a juice extractor take a potato and wash it real good and dry it then put it in the extractor and drink the juice of it, just one it will be like a half cup, tastes funny but it will work miraculously, try it and let me know. The way I did it because I don't have a juice extractor, I put the potato in the blender and added like 1/2 cup of water and I drank the juice that came out, since that day I have feel so relieve from my pain, I took it two nights and said to my self I will take it for 10 days but I didn't, I took it only for 2 days and I feel great.
