1) Coconut Water
I found an excellent home remedy for gastritis.  What you need to do is to drink some coconut water.  It allows the stomach to rest and supplies your system with some minerals and vitamins.  If you only have coconut water and nothing else for the first twenty-four hours of treating your gastritis; this will really help your stomach return to normal conditions.
 
2) Rice Gruel
Whenever there are problems with gastritis, I found that rice gruel works wonders as a natural treatment.  Just take one cup of rice gruel a couple times a day during your gastritis phase.  If your case is chronic, and the flow of gastric juice is poor, this type of food will be beneficial as it helps create a better flow of the gastric juice.

3) Potato Juice
I have discovered that potato juice is very good natural remedy for gastritis.  You can relieve your symptoms if you have a half cup of the juice two or three times each day.  You’ll want to drink this about thirty minutes before each meal.
 
4) Marigold Natural Remedy for Gastritis
If you’re experiencing problems with gastritis, try taking some marigold herb.  It is really effective for treating gastritis and is easy to use.  Just take a tablespoon a couple times a day until the symptoms go away.  This is one of the most effective gastritis natural treatments.
 
A good home remedy for gastritis, is to give your stomach a rest and allow the toxic conditions and inflammation to die down.  You can achieve this by going on a fast with only warm water going into your body.  You should do this for a couple of days or longer, depending upon the severity of your condition.

5) Fruit Diet
I suggest an all-fruit diet as a natural cure for gastritis.  Once the acute symptoms have gone down; you should go about three days eating nothing but fruit.  The types of fruit you should eat includes:  grapes, pears, oranges, melons, pineapple, peaches, and apples.
 
Your diet and the avoidance of things like alcohol, tobacco, and caffeine can greatly influence your ability to avoid problems with gastritis.  You should avoid sweets, rich cakes, pastries, and also aerated waters.  Additionally, your diet should exclude meat, red pepper, pickles, spices, condiments, and sour foods.  Considering what to avoid is one of the best home remedies for gastritis.
 
Here are some good tips that make for a good home remedy to treat and/or avoid gastritis.  When you eat your meals, be sure to take your time and completely chew your food.  Also, don’t drink water during meals because this can dilute the digestive juices and slow down digestion.  The last meal of your day should be at least two hours before you go to bed.  You shouldn’t have too many different type of foods mixed together in your meals.  You should include lots of yogurt and cottage cheese in your diet and be sure to drink eight to ten glasses of water each day.
