Goldenseal is a low perennial herb with a distinctive knotty, yellow rhizome from which arises a single leaf and an erect, hairy stem.

Above ground: Low-growing woodland herb with erect, hairy stem. In early spring, bears two 5-9 lobed, rounded leaves near the top. Single greenish-white flower terminates the stem.

Underground (the medicinal part): Rhizome is yellowish-brown color, about 5 cm (2") long and 1 cm (½") thick. Knotty, twisted, wrinkled appearance. Marked longitudinally and encircled by leaf scars. Rootlets frequently present in abundance. Taste is very bitter. Odor is strong, characteristic, and disagreeable.

Native to Canada and eastern United States. Found in shady woods and the edges of woodland on rich, moist soil.

Cultivation: Wild, but becoming rare due to over-wildcrafting. Some commercially grown in Oregon and Washington. Requires rich, moist, well-drained soil in shade, pH 6.0-7.0. Propagation by rootlets planted in fall or by division when dormant. Germination is slow and difficult — seeds must be freshly stratified. IMPORTANT: Root should be four years old before taking up for use.

Harvest: Rhizomes are lifted in the autumn after the foliage has died down, then dried.

Isoquinoline alkaloids (PRIMARY MEDICINAL COMPOUNDS):
Hydrastine — major alkaloid (unique to Goldenseal)
Berberine — major alkaloid with antimicrobial properties
Canadine (=tetrahydroberberine) — major alkaloid
Lesser amounts of related alkaloids

Miscellaneous: Fats · Acids · Resin · Polyphenolic acids · Small amount of volatile oils

Goldenseal is very different from Peppermint, Catnip, and Fennel in how it must be prepared. The berberine and hydrastine alkaloids extract much better with sustained heat AND acid than with simple steeping.

Extraction efficiency comparison:
Acidified alcohol tincture: 90-95% (most efficient)
Acidified water decoction: 70-85% (very good — recommended method)
Alcohol tincture (no acid): 70-80% (good)
Plain water decoction (no acid): 50-65% (mediocre)
Hot water tea (infusion/steep): 40-60% (poor)
Capsules/powder: 20-40% absorbed (worst)

Why this matters: Goldenseal's active alkaloids need both sustained heat AND acid to extract from the tough root material. Without simmering and acid, you're wasting most of the herb. This is different from Peppermint and Catnip, where boiling destroys the medicine. With Goldenseal, simmering with acid is essential.

Goldenseal may be used in infusion, decoction, tincture or capsules and tablets. We prefer to use the root. It is eligible for combination with almost any other remedy where a tonic is needed.

Directing Goldenseal to specific organs: Goldenseal is one of the very few agents that will tone and sustain the venous circulation. It can be made to specially influence the stomach, bowels, bronchi, urinary tract or reproductive organs by combining it with agents that specially influence the given part.

Examples of directing combinations:
Combined with Mitchella repens (Partridge Berry), its influence will quickly be manifest upon the genitalia.
Used with Juglans cinerea (Butternut), you have a powerful intestinal tonic.
If combined with Eupatorium purpureum (Gravel Root), the kidneys will soon feel its influence.

Note: In some cases it may be preferable to use the powdered Gum Myrrh in place of the Capsicum.

Goldenseal will always outperform Oregon Grape Root due to its unique combination of berberine AND hydrastine alkaloids, plus its venous tonic property which Oregon Grape Root does not possess.

However, Oregon Grape Root is a good second choice when Goldenseal is unavailable due to:

• Cost (Goldenseal is endangered and expensive)
• Ethical sourcing concerns
• Availability issues

Oregon Grape contains berberine (the antimicrobial alkaloid) but lacks the hydrastine and venous tonic properties that make Goldenseal unique. It is toning to the liver and gallbladder and will stimulate the flow of bile.

Standard adult dose: approximately 2.3g dried root per dose.

Dosing frequency: Goldenseal is traditionally given in "small and frequent doses." This means standard dose (~2.3g) taken multiple times throughout the day — not tiny amounts, but regular doses spaced frequently. Example: 2 tablespoons decoction every 2-3 hours for acute conditions.

Children's doses: Ages 6-12: Half adult dose · Ages 2-6: Quarter adult dose · Infants: Generally not recommended; consult practitioner

Standard ratio: 2.3g goldenseal root per 240ml (1 cup) cold water

1. Measure dried goldenseal root (powder or small pieces)
2. Place in pot with cold water
3. Add ~10ml (2 teaspoons) lemon juice or vinegar (4% of water volume) — this is CRITICAL for proper extraction
4. Cover with tight lid
5. Bring to simmer over medium heat — gentle bubbles, not rolling boil
6. Continue simmering gently 15-20 minutes, covered
7. Remove from heat and strain through fine mesh
8. Keep covered while drinking

For larger batches:
3 cups (720ml) water = ~30ml (2 tablespoons) lemon juice/vinegar
6 cups (1440ml) water = ~60ml (¼ cup) lemon juice/vinegar

Tincture preparation: Ratio 1:5 (1g root to 5ml alcohol, 40-60%). See General Reference Guide for 30-day process. Extraction efficiency is 90-95% — the most efficient method for goldenseal. Acidified alcohol tinctures extract even better.

Dried root: Store whole or in pieces in airtight glass jar. Keep away from light and heat. Shelf life 2-3 years. Should retain yellowish-brown color. Smell test: Should have strong, characteristic, disagreeable odor. Taste test: Should be intensely bitter. If odor weakens or becomes musty, replace.

Powdered root: Less stable than whole root. Store airtight, away from light. Use within 1-2 years. Should retain bright yellow color. If color fades significantly, potency is declining.

Prepared decoction: Drink same day for best potency. Refrigerate covered 24-48 hours maximum. Watch for fermentation or off-smell.

Tincture: Store in amber glass in cool, dark place. Lasts 5-7 years or longer. Should retain golden-yellow color.

Generally safe at recommended doses for non-pregnant adults.

Berberine cautions: High dosages may interfere with the metabolism of B vitamins. Use recommended doses only.

Taste and digestion: Very bitter and unpleasant taste — this is normal and expected. May cause digestive upset in sensitive individuals if taken on empty stomach.

Children: Use appropriate smaller doses; generally safe but intensely bitter

Drug interactions: May interact with medications metabolized by the liver; consult healthcare provider if taking prescription medications

Taxonomic note: The origin of the cultivated varieties is not really known, but many botanists believe they all arose from a single species, hence the botanical classification is uncertain and Capsicum annuum is often called C. frutescens. Roxburgh also called cayenne C. minimum. There are about 10 wild species and 4 or 5 domesticated species of shrubby annuals, biennials and perennials and numerous cultivars.

Main varieties:
Capsicum frutescens: Perennial shrub to 2m (6') with woody trunk. Leaves various, usually elliptical up to 10cm (4") long. Flowers white to yellowish in groups of 2 or 3 and followed by small, upright, fiery, green fruits that ripen to red.
Capsicum annuum: Herbaceous annual or biennial 60-75cm (24-30") tall with simple ovate leaves, bell-shaped solitary white flowers are followed by hollow fruits up to 15cm (6") long, which ripen to varying colors.
Capsicum microcarpum D.C. (syn C. annuum var. glabriusculu): Tender annual to 2m (6'), with ovate to lanceolate leaves up to 3cm (1¼") long with white flowers and very pungent, red, pea-sized fruit. Possibly the ancestor of the peppers. Birdseye pepper — some herbalists believe this is the most beneficial.

Cultivar groups: Most cultivated varieties belong to C. annuum var. annuum, and may be divided into 3 main groups: Cerasiform (cherry peppers); Coniodes (cone-shaped peppers); Fasciculatum (red cone peppers). Pungency is due to capsaicin, the presence of which is controlled by a single gene, so cultivars without it have sweet fruits (e.g. bell peppers). Any of the hot varieties can be used medicinally but the main ones are C. frutescens and C. annuum.

Native to tropical America. They were first described in 1493 by Dr. Chauca, the physician on Columbus' ship. They were introduced from South America to India and Africa by the Portuguese. Now grown in all tropical and subtropical countries and under glass or as an annual in temperate climes.

Cultivation: Rich well-drained soil in sun, minimum 18-21°C (64-70°F). Propagate by seed in early spring.
Harvest: Unripe fruits are picked when needed. Ripe fruits are dried and ground for cayenne pepper and other uses.

Capsaicin (0.1-1.5%) — THE PRIMARY ACTIVE COMPOUND: Mixture of dihydrocapsaicin, nordihydrocapsaicin, homodihydrocapsaicin, carotene, etc. (Vanillyl amide of isodecanoic acid alkaloid). This compound provides the pungent, stimulating properties. Capsaicin content determines pungency.
Vitamins: Ascorbic acid (Vitamin C) 0.1-0.5% · Thiamine · Vitamin A
Carotenoids: Red carotenoids 4-16%
Alcoholic extract: 20-25%
Additional constituents: Flavonoids and volatile oil · Steroidal saponins known as capsicidins in the seed

Method 1: As a Formula Enhancer (Most Common Use)
Add a pinch to any herbal tea to: speed circulation · enhance the action of other herbs · "drive" the formula through the body faster · increase effectiveness
Amount: A small pinch (1/8 teaspoon or less) per cup of tea
When to add: After straining the tea, add pinch to individual serving
Example: The General Reference Guide mentions adding "a pinch of cayenne" when straining herbal teas to speed their action.

Method 2: For Cramps and Stomach Pains
Direct warm infusion: 1/4 to 1/2 teaspoon cayenne powder added to 1 cup boiling water. Give in small doses as warm infusion. Useful for cramping and peristaltic action in parts previously contracted. This would be well-suited for giving in small, frequent doses rather than large amounts at once.

Method 3: External Applications
For cold feet: Sprinkle a little cayenne in shoes. Greatly assists circulation to cold feet. Caution: Don't use too much or feet will become too warm. Alternative: Sprinkle into socks.

Liniment for sprains, bruises, rheumatism, and neuralgia:
Tincture of Capsicum (Cayenne): 6ml (2 fluid ounces)
Fluid Extract Lobelia: 6ml (2 fluid ounces)
Oil of Artemesia absinthium (Wormwood): 4ml (1 fluid drachm)
Oil of Rosmarinus officinalis (Rosemary): 4ml (1 fluid drachm)
Oil of Mentha spicata (Spearmint): 4ml (1 fluid drachm)
Application: Rub into affected area as needed for pain relief and increased circulation.

Method 4: For Specific Conditions
Typhoid fever: Combine cayenne with Golden Seal (Hydrastis Canadensis). Cayenne will sustain portal circulation and gives much more power to the liver herbs used.
Hemorrhage from lungs: Place client in vapor bath. Give infusion of cayenne. The pressure will be taken from ruptured vessels. Good results obtained.
Diphtheria: Apply tincture of cayenne around the neck externally. Place flannel around neck wet with cayenne infusion. Use cayenne infusion internally at the same time freely.
Colds, sore throats, stomach conditions: Give warm infusion of cayenne in small repeat doses. About 10ml (two teaspoons) every half hour or more frequently if required. Particularly effective in acute stages.

As formula enhancer: A pinch (1/8 teaspoon or less) added to other herbal teas

For direct warm infusion: 1/4 to 1/2 teaspoon powder per cup of water · Take 10ml (2 teaspoons) every 30 minutes to 1 hour as needed

For external use: In shoes/socks: Light sprinkle only · As liniment: Apply to affected area as needed

Children: Use proportionally smaller amounts — cayenne is very potent

Infants: Generally not recommended for direct use; may benefit indirectly through mother's milk if mother consumes small amounts

Cayenne does not require special extraction methods — its active properties (capsaicin and pungency) are immediately present in any medium.

As powder: Most common form · Can be added directly to water, food, or other preparations · Sprinkled externally

As tincture: Standard 1:5 ratio in alcohol · Very potent — use by drops or small teaspoons

In warm water: Simply mix powder with hot water · No simmering or steeping required · The heat/spice is immediately present

Powdered cayenne: Store in airtight glass jar away from light and heat. Shelf life: 2-3 years. Should retain bright red color. Should smell pungent and spicy. If color fades or aroma weakens, replace.

Whole dried peppers: Store whole until ready to grind. Last longer than pre-ground powder. Grind as needed for freshest potency.

Tincture: Store in amber glass in cool, dark place. Lasts 5-7 years.

Generally safe when used appropriately in small amounts.

External use: Don't apply to broken skin without professional guidance · Too much in shoes can cause excessive warmth · Test small amounts first for sensitivity

Internal use: Start with very small amounts · Can cause burning sensation in mouth and digestive tract · May aggravate existing ulcers in some people (though traditionally used for ulcers in small doses) · Excessive use can cause gastric irritation

Children: Use very small amounts; cayenne is quite spicy for children

Pregnancy: Generally safe in food amounts; large medicinal doses should be used with professional guidance

Medications: May interact with blood thinners or blood pressure medications; consult healthcare provider

Stout, bristle-haired perennial 60-120 cm (2-4') tall on thick brownish-black mucilaginous rootstock.

Leaves and stem: Erect. Lower leaves to 25 cm (11") long, petiolate, lanceolate, hairy beneath. Upper leaves narrower.

Flowers: Purple, pink or whitish in crowded terminal cymes (monochasium). Flowers appear in early summer.

Taste: Somewhat sweet and slightly astringent.

Distribution: European and Asian native; introduced elsewhere. On rich, wet soils near rivers, streams, in ditches, low lying meadowland. To 1500 m (4800') in altitude.

Cultivation: Moist to wet soil in sun or partial shade. Propagate by seed sown in spring or by division. It is deep rooted and difficult to eradicate when established. Be sure leaves and stalks are wilted before putting in compost or the leaves will grow new plants.

Harvest: Leaves are picked in early summer before flowering and dried. Roots are lifted during Fall and Winter and dried.

Allantoin: Calculated 0.6% - 0.8% — Promotes cell proliferation and wound healing. This is the primary active constituent responsible for Comfrey's tissue-repair properties.

Pyrrolizidine alkaloids: Calculated 0.02 - 0.07% — These alkaloids have raised safety concerns (see Safety Considerations section for full discussion). Important to note: echimidine is present in some sources.

Mucilage (fructans): Abundant — Soothes and protects tissue, creates protective coating over inflamed areas.

N-oxides: Present in some sources.

Tannins: Calculated 4-6% — Provide astringent properties.

Starch and triterpenoids (isobornol): Present.

Sterols (sitosterol): Present.

Depsides of dehydrocaffeic acid (="lithospermic acid"): Calculated 1-3%.

Asparagine and amino acids (including γ-aminobutyric acid): Present.

Protein: Very high protein content; up to 35% — This exceptional protein content is what makes Comfrey such a powerful Nutritive herb.

The textbook notes: "Comfrey should be used in almost all combinations for fomenting."

TRADITIONAL INTERNAL USE (Historical Documentation Only):

In the past, Comfrey Leaf was used as a nutritive herb. Because of its exceptionally high protein content (up to 35%) and abundant minerals, the fresh leaves were eaten as greens (similar to how one would use lettuce or other nutritive leafy vegetables) and the dried leaves were used in teas. The purpose was to deliver nutrients directly to the tissues of the body so they would heal and repair faster. This made sense given Comfrey's classification as a Nutritive herb — it was feeding the body the building blocks it needed for tissue repair.

TRADITIONAL EXTERNAL USE (More Famous — The "Knitbone" Use):

However, Comfrey Leaf was MORE FAMOUSLY known for its external applications. The name "Knitbone" comes from the traditional practice of applying Comfrey leaves externally as fomentations (hot compresses) or poultices to support healing of bruises, sprains, swellings, and fractures. This external use was the primary and most recognized application.
