Goldenseal
has been used to treat mucous membrane infections caused by bacteria,
fungus or protozoa. These types of infections are commonly found
in the mouth, respiratory, gastrointestinal and genitourinary
tracts. Goldenseal is also used to treat inflammations of the
gall-bladder, and to correct some of the metabolic effects of
liver cirrhosis. Goldenseal root has been used by native Americans
for a wide range of ailments, especially for localized skin and
eye irritations. It is still used today as an ingredient in a
number of commercial sterile eye washes.

| Pharmacology
|
|
The
active ingredients of goldenseal include a group of alkaloids,
hydrastine, berberine & tetrahydroberberine
The
Alkaloids, primarily hydrastine and berberine have antiseptic
and astringent properties, and therefore help reduce inflammation
of mucous membranes.
The
Alkaloids also have an effect on inflammation, help to lower blood
pressure, and stimulate peristalsis.
Berberine
also has some antibiotic properties. A few clinical trials testing
berberine's antibiotic properties show that goldenseal can successfully
treat diarrhea caused by E.Coli (traveller's diarrhea), Shigella,
salmonella , Klebsiella and cholera. It has been shown that in
Vitro, berberine can inhibit many common bacteria, including Staphylococcus,
Streptococcus, Chlamydia, E. Coli, Psuedomonas and others. In
Vitro, Berberine has been shown to inhibit protozoa such as Giardia
and Trichomonas. In one study in pediatric patients, berberine
was shown to be as effective as metronidazole in control of Giardiasis.
Clinical studies have also been carried out to study the effectiveness
of goldenseal in the treatment of trachoma, an eye infection caused
by Chlamydia trachomatis In comparison to conventional therapy,
Berberine was found to be less effective in reducing acute symptoms
such as conjunctivitis and edema, but as effective in eradicating
the pathogen and preventing recurrences .

|
| Origin |
|
Goldenseal
is a perennial and it grows deep in moist rich woods along the
East Coast of North America, and has been used by Native American
healers for a wide range of conditions. In spring, the small erect
stems produce large hand-shaped flowers ,and dark orange-red berries.The
parts of the plant used medicinally are the dried rhizomes [underground
stems] and roots. Golden seal is now scarce in the wild , probably
because of over harvesting.
|
| Processing |
|
It
is processed with ethanol/water extraction at low temperature,
with pH adjusted for maximum yield and extraction.
