Oregon Grape Root

Also known as- Mahonia aquifolium and Berberis aquifolium.
Botanists disagree about the scientific name of this plant because it is a close relative to Barberry, allthough not identical.
Introduction
Oregon grape root is a tall,
evergreen, flowering shrub that grows among the firs, spruces, and pines of the
mountainous American Northwest. The state flower of Oregon, Oregon
grape root bears fruit but "grapes" is an inaccurate description.
Oregon grape root is a useful substitute for goldenseal, which has been over
harvested in the wild. It is not as fussy about its habitat than the closely
related barberry, and easier to find.
As a purely bitter herb, Oregon grape root is used easily with Traditional
Chinese Medicine, having the same function and only a little less potency than
coptis. Like coptis, Oregon grape root is useful in treating the various
symptoms of "damp heat," such as:
´ Abdominal fullness and distention
´ Constipation alternating with diarrhea
´ Foul-smelling loose stools,
´ General feeling of heaviness,
´ Nausea,
´ Reduced appetite,
´ Reduced thirst although with the sensation of dry mouth,
´ Sticky, thick, and yellow or green mucous discharges,
´ Watery, oozing skin eruptions, and
´ "Red" symptoms: red tongue, hot flushes, bad temper, rapid pulse.
(Practitioners of Traditional Chinese Medicine are likely to note that Oregon
grape root is less appropriate than coptis in treating syndromes in which there
is a "deficiency of Yin," an inherent tendency to lose fluids.)
Oregon grape rootÍs best-researched application in modern herbal medicine,
however, is in the treatment of chronic inflammatory skin conditions, such as
psoriasis.
Constituents
Oregon grape root contains berberine, also found in barberry, coptis, and goldenseal. The herb also contains phytochemicals with similar activity, including columbamine, hydrastine, jatrorrhizine, oxyacanthine, and tetrahydroberberine, as well as tannins. It does not contain the range of nutrient vitamins and minerals found in barberry.
Parts Used: Root
Typical Preparations
Topical creams containing 10%
tincture of Oregon grape root.
Also used as tea, tincture and it may be administered in capsule form.
Proper dosage is important:
´ Tea: 1 to 2 grams (1/2 to 1 teaspoon) of dried root steeped in 150 ml
(approximately 2/3 of a cup) of hot water for 10 to 15 minutes three times
daily. This is not the same dosage as for the chopped herb.
´ Tincture: 3 to 6 ml.
(1/2 to 1-1/2 tsp) three times daily (but no more than three doses of any kind
of Oregon grape root product per day).
´ For skin disorders: 10% tincture in ointment, applied to the skin three times
daily
Summary
Traditional herbal medicine
uses Oregon grape root to stop diarrhea. It slows the passage of stool through
the small intestine, but it also keeps bacteria from implanting themselves in
the lining. Oregon grape root may also give the immune system a mild boost by
encouraging phagocytosis, the engulfing and digesting of bacteria by the white
blood cells known as microphages.
Oregon grape root and other herbs that contain berberine are scientifically
proven to protect against bacteria, viruses, fungi, protozoans, helminthes
(worms), and chlamydia. Conditions treated by Oregon grape root include
bacterial diarrhea, intestinal parasites, and ocular trachoma. Oregon grape
root may increase blood platelet counts and counteract the proliferation of
cancerous tumors of the bladder and colon. It has a sedative effect on the
smooth muscles lining the digestive tract and can relieve stomach cramps and
abdominal pain.
Why use Oregon grape root as a whole herb? Why not just take a berberine
concentrate?
Oregon grape root contains tannins that cross link proteins in the linings of
the nose and throat, or in the digestive tract, to seal them against infection.
The tannins may also explain the herbÍs usefulness in treating psoriasis, a
condition characterized by the over-rapid multiplication of cells in the skin.
In at least one clinical study, a cream containing Oregon grape root eased
inflammation, irritation, and itching.

Precautions
Adults should limit use of
Oregon grape root or any other herb containing berberine (barberry, coptis, or
goldenseal) to seven consecutive days at a time, waiting at least a week before
using the herb again. This gives the natural, helpful bacteria of the intestine
a chance to recover. Taking vitamin B6 supplements can give infectious bacteria
resistance to the antibacterial toxins in the herb.
Do not take Oregon grape root if you are taking antibiotics for diarrhea.
The herb is not a problem for nursing mothers unless the baby has jaundice,
however it should not be used while pregnant.
