Herbalism (AKA phytotherapy) is one of the oldest known systems of medicine and is a basis of traditional medicine. It is the ancient practice of using herbs and natural materials for their medicinal properties. The holistic approach looks at natural prevention as well as treatment. Homeopathy is a type of alternative medicine dating 200 years, based on the idea that "like cures like". It is said to stimulate the body's healing response by administering natural substances that mimic the symptoms of a disease/issue.
