Cranberries contain citric, chinic, benzoic and oleic acids, vitamins C and P, carotene, saponins, amino acids, routine, quercetin, glycoside, microelements (iodine, iron, copper, manganese. They've been shown in some research, to have a role in supporting urinary tract health.
Bioflavonoids are hydroylated phenolic structures synthesised by plants and have previously been shown to have activity against bacteria, fungi and viruses. In particular, bioflavonoids have been recognised as both anti-inflammatory and bacteriostatic agents limiting the growth of certain bacteria associated with periodontal diseases. They’ve been shown to reduce gingival inflammatory conditions in people.
Green tea is particularly rich in health-promoting flavonoids including catechins and their derivatives. The most abundant catechin in green tea is epigallocatechin-3-gallate, which is thought to play a pivotal role in the green tea’s anticancer and antioxidant effects. It has also been suggested that green tea also promotes periodontal health by reducing inflammation, preventing bone resorption and limiting the growth of certain bacteria associated with periodontal diseases.
The use of thyme, because of its various antiseptic and antioxidant properties, is widely reported in gingivitis, stomatitis, and bad breath. You could even argue it’s like Listerine for dogs. A component of thyme, known as thymol, appears to inhibit growth of oral pathogens in the mouth and in combination with other essential oils, may reduce tooth decay. Thymol is one of the essential oils with antibacterial effects found in the human mouthwash, Listerine.
Sage has a range of therapeutic activities including antibacterial, antiviral, antifungal, and antioxidant effects. Volatile monoterpenoid is a major constituent, reported to be an effective antibacterial. Sage has been shown to have an antibacterial action against streptococcus mutans in dental plaque, in people. Streptococcus mutans, along with porphyromonas gingivalis and candida albicans, is an oral pathogen responsible for bad breath and tooth decay.
Lysozyme is an antibacterial enzyme, present in all body fluids, including saliva. In the oral cavity, lysozyme plays an important role in controlling microbial overgrowth, reducing the number of bacteria in the dental biofilm, decreasing colonisation, and modifying bacterial metabolism. In particular, it’s been shown to inhibit glucose fermentation by oral streptococci and help prevent dental plaque.
Blackcurrant fruit contains polyphenolic substances with antioxidant, antimicrobial, antiviral, and antibacterial properties. Various studies have highlighted the antibacterial activity exerted by ribes nigrum (blackcurrant) juice on bacterial strains - in particular streptoccocus mutans, porphyromonas gingivalis and candida albicans - associated with gingival inflammation, oral malodour, and dental caries formation.
