Botanical Name : Hydrastis canadensis
Species: H. canadensis
Habitat :Goldenseal is native to North America, and can be found growing wild from Ontario to Arkansas, across the southeastern U.S. to Georgia and cultivated in Oregon and Washington. The main growing region used to be Ohio valley, before it became the area fell victim to deforestation and development.
It grows in the rich soil of shady woods and moist places at the edge of wooded lands. Goldenseal prefers open hardwood forests, with rich humic soils, and a slight slope around 5% to facilitate drainage. Plants are found to be most vigorous in stands with 60-65% shade, and pH values between 5.5 and 6.5.
Goldenseal has a thick, yellow rootstock which sends up an erect hairy stem about 1 foot in height which branches near the top, one branch bearing a large leaf and another a smaller leaf and a flower.The stem is purplish and hairy above ground and yellow below ground where it connects to the yellow rhizome. The plant bears two palmate, hairy leaves with 5–7 double-toothed lobes and single, small, inconspicuous flowers with greenish white stamens in the late spring.
The rhizome is thick, sarcous, oblong, irregular, and knotted, having a yellowish-brown, thin bark, and a bright-yellow interior; rootlets numerous, scattered, coriaceous fibres.This low perennial herb grows from 6 to 10 inches high, its leaves and fruit much resembling those of the raspberry. The flowering stem, which is pushed up early in the spring, is from 6 to 12 inches high, erect, cylindrical, hairy, with downward-pointing hairs, especially above, surrounded at the base with a few short, brown scales. It bears two prominently-veined and wrinkled, dark green, hairy leaves, placed high up, the lower one stalked, the upper stalkless, roundish in outline, but palmately cut into 5 to 7 lobes, the margins irregularly and finely toothed. The flower, which is produced in April, is solitary, terminal, erect, and small, with three small greenish-white sepals, falling away immediately after expansion, no petals and numerous stamens.It bears a single berry like a large raspberry with 10–30 seeds. The fruit ripens in July and has the superficial appearance of a raspberry, with small, fleshy, red berries, tipped with the persistent styles and containing 1 or 2 black, shiny seeds. However, it is not edible.
Goldenseal can be grown both from seed and from the rhizome. It requires a partially shaded situation (60 – 70%), in a well draining, rich humus soil. Rootstocks can be divided into small pieces and set at least 8” apart. Planting should be undertaken in the autumn. The plants should be allowed to grow for 2 – 3 years before harvesting, though by the 4th year the roots are said to become too fibrous for medicinal use. Transplanting may be undertaken at any time. According to an American grower 32 healthy plants set per square yard will produce 2 lb of dry root after three years of growth. The fresh rhizome is juicy and loses much of its weight in drying. When fresh, it has a well-marked, narcotic odour, which is lost in a great measure by age, when it acquires a peculiar sweetish smell, somewhat resembling liquorice root. It has a very bitter, feebly opiate taste, more especially when freshly dried. The rhizome is irregular and tortuous, much knotted, with a yellowish-brown, thin bark and bright yellow interior, 1/2 inch to 1 1/2 inch long, and from 1/8 to 1/4 inch thick. The upper surface bears short ascending branches, which are usually terminated by cup-like scars, left by the aerial stems of previous years. From the lower surface and sides, numerous thin, wiry, brittle roots are given off, many of them breaking off, leaving small protuberances on the root. The colour of the rhizome, though yellow in the fresh root, becomes a dark, yellowish brown by age; that of the rootlets and the interior of the root are yellow and that of the powder still more so. When dry, the rhizome is hard and breaks with a clean, resinous fracture, the smooth, fractured surface is of a brownish-yellow, or greenish-yellow colour, and exhibits a ring of bright yellow, somewhat distant narrow wood bundles surrounding large pith.
Goldenseal contains the isoquinoline alkaloids: hydrastine, berberine, berberastine, hydrastinine, tetrahydroberberastine, canadine, and canalidine. A related compound, 8-oxotetrahydrothalifendine was identified in one study. One study analyzed the hydrastine and berberine contents of twenty commercial goldenseal and goldenseal-containing products and found they contained variously 0%-2.93% hydrastine and 0.82%-5.86% berberine. Berberine and hydrastine act as quaternary bases and are poorly soluble in water but freely soluble in alcohol. The herb seems to have synergistic antibacterial activity over berberine in vitro, possibly due to efflux pump inhibitory activity.
Multiple bacteria and fungi, along with selected protozoa and chlamydia are susceptible to berberine in vitro. Berberine alone has weak antibiotic activity in vitro since many microorganisms actively export it from the cell (although a whole herb is likely to work on the immune system as well as on attacking the microbes and hence have a stronger clinical effect than the antibiotic activity alone would suggest). Interestingly, there is some evidence for other berberine-containing species synthesizing an efflux pump inhibitor that tends to prevent antibiotic resistance, a case of solid scientific evidence that the herb is superior to the isolated active principle. However, it is not yet known whether goldenseal contains a drug resistance efflux pump inhibitor, although many antimicrobial herbs do.
