The antioxidant sub-group known as flavonols provides a variety of condition-specific protection in the body -- and consumers are desiring dietary supplements that provide them with the nutritious support they feel they need.
Myricetin, a flavonol found in the bark, leaves and roots of the herb Bayberry, is a potent antioxidant that has been identified by world-famous biochemist Albert Szent-Györgyi in 1938, and thus has a lengthy history of scientific research into its actions. For example, studies have determined that myricetin acts as an astringent and as a stimulant; in large doses, it was shown to act as an emetic, which serves purpose in medical settings where ridding the stomach of suspected poison is necessary. Historically, bayberry (and thus my-ricetin) has been used for diarrhea, jaundice, and chronic inflammation of the throat. Today, worldwide, myricetin is widely used in the field of pharmacy, supplements and cosmetics.
 New research shows that myricetin can protect the structural integrity of deoxyribonucleic acid (DNA,   a carrier of important genetic information). Additionally,

myricetin can reduce inflammation within the body, reduce blood levels of low density lipoprotein (LDL) cholesterol (which keeps the heart healthy) and treat diarrhea. Also, a small number of studies strongly suggest that myricetin may also be a key nutrient for brain health and lower risk of development of Alzheimer's disease and Parkinson's disease, although more research needs to be performed before these health benefits can be linked concretely with myricetin consumption.

We use advanced technology to extract the active ingredient, the flavonol myricetin, from bayberry, and offer it as follows:

(1) Myricetin is available 80%, in powder form tested by HPLC.
(2) Myricetin is available 90%, in powder form tested by HPLC.

We look forward to always better serve our esteemed customers. For more information: info@cactusbotanics.com
