The most efficient route of administration for oral homeopathic medicines is sublingual absorption (under the tongue). To allow for better absorption, homeopathic medicines should be taken in a mouth free of strong flavors or anything that may coat the mouth.
We recommend taking the medicine 15 minutes before or after eating, drinking, or brushing your teeth (unless otherwise indicated on the box). Whatever food particles or flavors remain in your mouth may interfere with or delay absorption. However, there is no reason for food consumption to be staggered or withheld due to digestive interaction. Since the absorption takes place through the mucous membrane coating on the inside of the mouth, food in the stomach has no influence.
