  • Phloretin
    • Phloretin is a polyphenolic compound in the sub-group flavonoids and is mainly derived from apples. It is a potent antioxidant and has been shown to inhibit several types of destructive enzymes. Phloretin is known to absorb to lipid surfaces, such as cell membranes.
  • Ferulic Acid
    • This effective, polyphenolic antioxidant is a substance found in the seeds and leaves of most plants, especially in the brans of grasses such as wheat, rice and oats. Its chemical structure strongly resembles that of curcumin, also a potent polyphenol. Pholyphenols are so named because they have multiple phenolic constituents.

Other Natural Ingredients

  • Menthol Peppermint Oil
    • Menthol is a purified compound from peppermint oil. Mentol is responsible for imparting a cooling, soothing effect; a property present in whole peppermint oil, but multiplied in pure menthol. In addition to this flavoring ability, for which it is mostly used, peppermint oil has excellent antibacterial and antifungal properties. In a study published in Mycopathologica in 2008, the inhibitory effect of 30 plant oils including peppermint was evaluated agaisst biofilm forming Candida albians strain (CA I) isolted from clinical samples. Peppermint oil showed 74.16% biofilm reduction.
  • Thyme
    • Thymol is a natural phenol compound derivative found in oil of thyme, and extracted from Thymus vulgaris and various other kinds of plants. Thymol also provides the distinctive, strong flavor and is part of a naturally occurring class of compounds known as biocides, with strong antimicrobial attributes. Numerous studies have demonstrated the antimicrobial effects of thymol, ranging from inducing antibiotic susceptibility in drug-resistant pathogens to powerful antioxidant properties. Thymol has also demonstrated antifungal activity and anti-inflammatory effects including inhibition of postraglandin synthesis.
  • Sage Oil
    • Sage, Salvia officinalis, has a long history of medicinal uses. It has been used to stop bleeding wounds, treat ulcers and swelling and–internally–to treat sore throats and coughs, as well as dental abscesses, infected gums and mouth ulcers. Recent in vitro studies clearly showed that sage oil can interrupt inflammatory response paths, most likely from its content of rosmarinic acid. Sage oil has also revealed an antioxidant capability and it is a constituent of many dental hygiene products.
  • Clove Flower Oil
    • Sourced from the leaves, flower buds or fruit of a tree native to South America, clove is a natural substance known for its antibacterial capabilities and its anesthetic powers. In a high concentration, it was found to be as effective as a 20% benzocaine gel in preventing pain from needle sticks. In a low concentration, it is effective to alleviate symptoms of irritation in the oral cavity and provide antibacterial support.
  • Xylitol
    • Found in the fibers of many fruits and vegetables is a sugar alcohol sweetener used as a naturally occurring sugar substitute. Xylitol is specific in its inhibition of the mutans streptococci group, bacteria that are significant contributors to tooth decay.
