2. Natural & Biological Based CAM Therapy
Biologically based therapies use naturally occurring substances to improve health and enhance natural body healing and wellness.
National Center for Complementary and Integrative Health (NCCAM), defines use of natural (herbal medicines or botanicals) and biological substances (vitamins, minerals, amino acids, fatty acids, whole diets, functional foods) and other products as "biologically based CAM practice". Many products in these categories are available as "over the counter" dietary supplements. CAM "Natural products" such as probiotics—live microorganisms (usually bacteria) that are normally found in our guts also have beneficial effects. Probiotics are available in foods (e.g., yogurts) or as dietary supplements. However, Taking a multivitamin to meet minimum daily requirements is not considered as CAM practice.
