what medicine for ulcer and is it a good one?

Zantac is the most common medicine prescribed to stomach ulcer. It is not bad but you have to take it consistently. There's another one called WEISEN-U, made by the Japanese. This is a very effective medicine too. If you still feel very painful, prepare some lotus root powder, blend it with some water and honey to serve. It can kill the pain immediately and can seal the spot where ulcer happens. Drinking lotus root soup help soothing too. Also, eating at a regular time everyday will speed up recovery. Finally, do NOT eat or drink anything cold.
