Hi,

Folklore has been making the same claim about the medicinal properties of Currants (black in particular) for ions.

It is always nice when folklore and science meet. (smile)

Regards,
Tom

Black Currant Claims
Black currants contain anthocyanidins, ellagic acid .  Both act as antioxidants, thus
as anti-cancer substances that may help protect cells. Ellagic acid has more than one anti-cancer activity.  Anthocyanidins may also protect against  heart disease. Berries are also rich in soluble fiber, which may help reduce cholesterol.

Blueberries, cranberries, huckleberries and related plants have now been
found to contain resveratrol, a potential anticancer agent, according to
Agricultural Research Service scientists who made the discovery.

This new finding from ARS chemist Agnes Rimando at the Natural Products
Utilization Research Unit, Oxford, Miss., adds to previous research by other
scientists who found that dark-skinned bunch grapes contain resveratrol.
Rimando is working with scientists at Agriculture and Agri-Food Canada,
Kentville, Nova Scotia, and the ARS Small Fruit Research Station in
Poplarville, Miss.

Using chemical identification procedures, the team of scientists measured
the resveratrol content of 30 whole fruit samples of blueberry, cranberry,
huckleberry and related plants. The samples represented five families and 10
species of Vaccinium fruit. They also measured resveratrol in skin,
juice/pulp and seed samples of muscadine grape.

Because of its important biological properties, resveratrol
(3,5,4-trihydroxystilbene) has been examined extensively in grapes. Studies
showed the compound protects the grapes from fungal diseases. It also
provides health benefits for consumers by reducing the risk of
cardiovascular disease. The compound's anticancer potential warranted its
examination in other fruits.

The team's studies showed that several fruit samples of Vaccinium contain
varying amounts of the compound. Analysis of the extracts of the skin,
juice/pulp and seed of muscadine grapes showed that concentration of
resveratrol in the skin was highest. Levels in the juice/pulp were much
lower than in the skin and seeds. Analysis of more Vaccinium and muscadine
samples is continuing.

The new data could help build a foundation for increasing resveratrol in
those berry and grape crops that are important to many small farmers. Future
research goals will include enhancing production of resveratrol in selected
species.

ARS is the lead scientific research agency of the U.S. Department of
Agriculture.
