Guava leaf Extract Specification: 5:1, 10:1
Description: The bark and leaf extracts of guava (Psidium guajava) have shown to have in vitro toxic action against numerous bacteria. The leaves of guava are rich in flavonoids. The flavonoids have demonstrated anti-bacterial activity. This anti-bacterial property of guava leaves is what causes benefit to the teeth and gums.
Function: The effects of guava leaf extract on the bleeding time and the three main mechanisms of haemostasis: vasoconstriction, platelet aggregation and blood coagulation, were investigated. The water extract of guava leaves did not shorten bleeding times in rats. Guava leaf extract potentiated the vascular muscle contraction induced in rabbits by phenylephrine, and when given alone it stimulated human platelet aggregation in vitro in a dose-dependent manner. |
