Hawthorn extract vitexin,China OHI price supplier

Hawthorn (Crataegus oxyacantha), a rose family member popularly planted along hedges to deter trespassers with its prickly branches, has heart-healthy properties that ancient Greeks and Native Americans recognized centuries ago. Its modern reputation as a healing agent dates to Victorian times, when an Irish physician's secret heart formula was ultimately revealed to contain a tincture made from the bright red berries.

Hawthorn is now a frequently prescribed heart remedy in Europe. A potent antioxidant, it appears to work by opening up blood vessels that feed the heart, thus increasing this muscle's energy supply and enhancing its pumping power. It also helps to relieve mild or stable angina (chest pain), control high blood pressure, strengthen heart function, and reinforce a normal heartbeat.

Hawthorn extracts should be standardized to contain at least 1.8% vitexin, also known as vitexin-2"-rhamnoside. This is the herb's primary active ingredient.
