Botanical Name :Hydrastis canadensis
Species: H. canadensis
Common Names:Goldenseal , orangeroot or yellow puccoon
Habitat :Hydrastis canadensis is native to southeastern Canada and the northeastern United States. Eastern N. America – Connecticut to Minnesota, Missouri and Kansas.It grows in rich shady woods and moist areas on woodland edges. Mesic, deciduous forests, often on clay soils at elevations of 50 – 1200 metres.
Hydrastis canadensis is a perennial herb. It may be distinguished by its thick, yellow knotted rootstock. 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 and the seeds ripen from July to August. The flowers are hermaphrodite (have both male and female organs) It bears a single berry like a large raspberry with 10–30 seeds in the summer.

It is hardy to zone 3.
Goldenseal is somewhat difficult of cultivation, it prefers a good rich moist loamy leafy soil in shade or partial shade. Prefers a sandy, acid to neutral humus-rich soil. Grows best in a pH range from 6 to 7. Plants are hardy to at least -15°c. Goldenseal is grown commercially as a medicinal plant, but it is not easy to establish the plants[4, 200]. Another report says that all goldenseal root that is used medicinally comes from wild plants. Since the plant is becoming increasingly rare in many parts of its range, it is probably wise to try and find alternatives to this species for medicinal use unless you can be sure that your supply comes from cultivated plants.
Seed – sow autumn or early spring in a moist sandy loam in a shady part of the cold frame or greenhouse. The seed is slow to germinate. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in light shade in the greenhouse for the first year or two. Plant out into their permanent positions when the plants are dormant. Division of the roots in autumn. The roots can be divided into quite small pieces and can also be transplanted at almost any time of the year. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
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

Goldenseal is a traditional medicine of the North American Indians and is still widely used in Western herbal medicine. In the Nineteenth century it acquired a reputation as a heal-all and was grossly over-collected from the wild and has become rare in the east of its range. It is now being cultivated on a small scale. It is especially valued in treating disorders of the digestive system and mucous membranes and is also extremely useful in the treatment of habitual constipation. The root is the active part of the plant, it is harvested in the autumn after the plant has died down and is dried for later use. It is said to be antiperiodic, antiseptic, astringent, cholagogue, diuretic, laxative, stomachic, tonic. It is used mainly in the treatment of disorders affecting the ears, eyes, throat, nose, stomach, intestines and vagina. The root contains the alkaloids hydrastine, berberine and canadine. Berberine is antibacterial (effective against broad-spectrum bacteria and protozoa), it increases bile secretions, acts as an anticonvulsant, a mild sedative and lowers blood pressure. Use of this plant destroys beneficial intestinal organisms as well as pathogens, so it should only be prescribed for limited periods (a maximum of three months). The plant should be used with caution, and not at all during pregnancy or by people with high blood pressure. An infusion of the root is used externally as a wash for skin diseases, vaginal infections, gum diseases etc.
At the time of the European colonization of the Americas, goldenseal was in extensive use among certain Native American tribes of North America, both as a medicine and as a coloring material. Prof. Benjamin Smith Barton in his first edition of Collections for an Essay Toward a Materia Medica of the United States (1798), refers to the Cherokee use of goldenseal as a cancer treatment. Later, he calls attention to its properties as a bitter tonic, and as a local wash for ophthalmia. It became a favorite of the Eclectics from the time of Constantine Raffinesque in the 1830s.
The Eclectics used goldenseal extensively for cancers and swellings of the breasts, although they did not consider it sufficient for cancer alone. Hale recommended its use in hard swellings of the breast, while conium was used for smaller painless lumps. The two herbs alone or with phytoplankton Americana were used for cancers, along with alternatives like red clover.
Herbalists today consider goldenseal an alterative, anti-catarrhal, anti-inflammatory, antiseptic, astringent, bitter tonic, laxative, anti-diabetic and muscular stimulant. They discuss the astringent effect it has on mucous membranes of the upper respiratory tract, the gastrointestinal tract, the bladder, and rectum (applied topically), and the skin. Goldenseal is very bitter, which stimulates the appetite and aids digestion, and often stimulates bile secretion
There is currently insufficient evidence to determine whether goldenseal is effective for any conditions
Dye and Repellent.
A yellow dye is obtained from the whole plant. It is obtained from the root. The pounded root is smeared on the body to act as an insect repellent.
Known Hazards:The whole plant is poisonous
Goldenseal has an affinity for mucosa, and is cooling so should not be used if an infection is at an early stage or there are more chills than fever. Goldenseal should be used with caution only while sick with illnesses that respond to hydrastine and berberine. It should generally not be taken for an early stage Upper Respiratory Infection (URI), but reserved for illnesses in which there is yellow or green phlegm. Generally a two-week maximum dosage is suggested. Taking goldenseal over a long period of time can reduce absorption of B vitamins. Avoid goldenseal during pregnancy and lactation, with gastrointestinal inflammation, and with proinflammatory disorders.A recent study (2011) found rats fed with Goldenseal constantly for two years had a greater tendency towards tumor formation.
Goldenseal has been found to have inhibited cytochrome P450 CYP2D6, CYP3A4, and CYP3A5 activity by approximately 40%, a statistically and clinically significant reduction. CYP2D6 specifically is a known metabolizer of many commonly used pharmaceuticals, such as antidepressants (including all SSRIs except for fluvoxamine), neuroleptics, and codeine. Combining Goldenseal with such medications should be done with caution and under the supervision of a doctor as it can lead to serious – perhaps fatal – toxicity. Those with a genetic deficiency in these enzymes are at particular risk.
Use for masking illicit drug use in urine drug tests:
Goldenseal became a part of American folklore associated with chemical testing errors, from pharmacist John Uri Lloyd’s 1900 novel Stringtown on the Pike. In the book, the victim’s habit of taking goldenseal in the form of digestive bitters, causes this herb to appear as the poison strychnine in a chemical test – thus suggesting murder. It has been used on occasions in this century to attempt to mask the use of morphine in race horses (without success).
Two studies have demonstrated no effect of oral goldenseal on urine drug assays over water alone. Subjects who drank large amounts of water had the same urine drug levels as subjects who took goldenseal capsules along with the water.
Goldenseal is in serious danger due to overharvesting. Goldenseal became popular in the mid-nineteenth century. By 1905, the herb was much less plentiful, partially due to overharvesting and partially to habitat destruction. Wild goldenseal is now so rare that the herb is listed in the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) goldenseal is one of the most overharvested herbs. More than 60 million goldenseal plants are picked each year without being replaced. The process of mountain top removal mining has recently put the wild goldenseal population at major risk due to loss of habitat, illegality of removing goldenseal for transplant without registration while destruction in the process of removing the mountain top is permitted, and increased economic pressure on stands outside of the removal area.
Many herbalists urge caution in choosing products containing goldenseal, as they may have been harvested in an unsustainable manner as opposed to having been organically cultivated.
There are several berberine-containing plants that can serve as useful alternatives, including Chinese coptis, yellowroot, or Oregon grape root.
