Sore throat? Coming down with the flu? It may
be time for some bitter Native American medicine known as goldenseal.
Despite its foul taste, the immune-stimulating herb -- often combined
with echinacea to treat colds, flu, Candida overgrowth and the
infections underlying diarrhea and bladder problems -- is so popular
and overharvested that it's an endangered plant species. Fortunately,
goldenseal's chief antimicrobial components, berberine and hydrastine,
are found in many other herbs commonly used in Chinese and Indian medicine.
Studies show that berberine inhibits the growth of parasites such as
Giardia and bacteria that cause acute diarrhea such as Shigella,
E. coli and Salmonella. Because berberine prevents streptococci
bacteria from attaching to the throat lining, goldenseal can help treat
strep throat (but also see a doc). And the herb's strong astringent
and anti-inflammatory effect on mucous membranes makes it especially
useful for treating cold and flu symptoms. For PWAs with the sniffles,
a little goldenseal for a few days may go a long way toward relief.
