In healthy people, the intestinal microflora consists of balanced amounts of symbiotic microorganisms, providing nutritional benefits to the host. This balance depends on our dietary habits and can easily be disturbed by unhealthy diets or drugs, such as antibiotics. Under these conditions, opportunistic microorganisms, such as the fungus Candida albicans, can colonize various body parts including the small and large intestine. If harmful microorganisms proliferate, the equilibrium is disturbed, and it becomes difficult even for indigenous bacteria to maintain their necessary territory. Herbs and other natural food components may help to support the body in maintaining a healthy microbial balance.€ Grapefruit seed extract (GSE) is known to have beneficial support in maintaining a balanced equilibrium within the body. Data have shown GSE to have supportive properties against a wide range of potentially unwanted organisms. The olive tree (Olea europaea) contains a major class of polyphenols. These polyphenols, including oleuropein and derivatives, may provide protection against certain microorganisms. Studies have demonstrated oleuropein’s growth inhibition of undesirable microorganisms as well as its important roles in cardiovascular health. Berberine, a natural isoquinoline alkaloid found in many medicinal herbs with a history of usage in Ayurvedic and Chinese medicine dating back approximately 3,000 years, has shown to help maintain a healthy microbial balance.€ Burdock has been used for centuries for detoxification support. Black Walnut has traditionally been used to support the body’s normal defense against parasites. Goldenseal has unique properties for microbial balance as well immune-supportive functions.
