My 15 year old daughter has always had stomach issues. When she was 4, she was under the care of a gastroenterologist because they thought she may have a form of inflammation that usually affects the intestines, but may occur anywhere from the mouth to the end of the rectum. or an immune reaction to eating gluten, a protein found in wheat, barley and rye.
When she has problems with her stomach, she automatically asks for the digestive blend and asks me to rub a couple of drops over her stomach and within seconds, her stomach is calm. There was an incident when I was not home and I happened to have the bottle of the digestive blend with me. She remembered my telling her about one of the oils in that blend (Fennel). I have a bottle of fennel and she found it and used that while I was gone and said it worked too, but not as well as her digestive blend.
