Yeast Formula™

How Does It Work?

The human body is host to literally millions of organisms, mostly bacteria but also some yeast. The relationship between bacteria and host is complex, and many bacteria are considered beneficial to human health, while others need to be kept in check by the immune system. Unlike probiotic bacteria, yeasts are not considered beneficial inhabitants of human intestinal or epithelial tissues. Although it is normal to host a small number of yeast organisms, it is important that the immune system remains strong enough to keep these organisms in line so that a healthy balance of these organisms is not disrupted.

Several herbs, particularly those containing volatile oils and certain alkaloids, have been shown to balance the growth of yeast, and thus may support a healthy balance of these organisms in the body.^*

Oregano: Oregano (Origanum vulgare) oil exhibits antioxidant activity and supports healthy balance of human microflora.† The herb contains several important constituents, including up to 3% volatile oils such as carvacrol, thymol, and borneol. Oregano oil also contains flavonoids, triterpenes (such as ursolic acid), rosmarinic acid, vitamin C, vitamin A and phytosterols.1 The oil and its constituents have been shown to support healthy yeast balance.†2-9^*

Peppermint: Peppermint (Mentha piperita) contains menthol, which is known to control growth of bacteria, fungi and yeast. Among many other plants tested, peppermint has demonstrated the highest yeast-balancing activity.†10-14 Like oregano, it also exhibits antioxidant activity.15^*

Thyme: Thyme (Thymus vulgaris) has been used traditionally as a remedy to support the health of the respiratory and digestive systems.†16,17 The main active constituent, thymol, has been shown to be active in controlling yeast growth.†18-24 Thyme extracts also support healthy neutrophil production and proper balance of inflammatory mediators.†25^*

Goldenseal: Goldenseal (Hydrastis canadensis) contains alkaloids that have been shown to possess beneficial activities in support of immune function and stable flora throughout the body.†26 Berberine has displayed moderate but significant activity on different species of yeast.†27^*
