Polysaccharides[4]

Water-soluble polysaccharides associated with immune-stimulating activity, particularly from the aerial parts.

Polysaccharides
Proanthocyanidins (A-type PACs)[2, 4]

Proanthocyanidins
Anthocyanins[4]

Red pigments and antioxidants of the fruit.

Anthocyanins

Safety, Cautions & Contraindications

Safety note[15, 16, 17]Caution

Generally considered safe, but caution advised for those with autoimmune conditions. Not recommended for long-term use (more than 8 weeks continuously).

Safety note[15, 16, 17, 18]Caution

Duke (2002) rates echinacea as +++ — among the most thoroughly documented herbal immunostimulants. It notes experimental and clinical evidence for immunostimulant, antiviral, and anti-inflammatory activities. Multiple species have been studied (E. purpurea, E. angustifolia, E. pallida), and Duke emphasizes that species identification in commercial products is often unreliable. Commission E approves E. purpurea for supporting immune function during colds and flu. Dose: 900 mg standardized extract daily in acute use; use should be limited to 8 weeks continuous. Contraindicated in autoimmune diseases (MS, lupus, HIV/AIDS), tuberculosis, and with immunosuppressive drugs (cyclosporine) (Duke, 2002).

Safety note[11, 12, 13]Info

Food amounts are generally considered safe (berries in meals, drinks, sauces). (Williams et al., 2023).

Safety note[11, 12, 13, 14]Info

Duke (2002) includes cranberry primarily at the experimental level for its astringent, diuretic, and antioxidant properties. Commission E has not approved cranberry for specific indications, though there is evidence supporting its role in preventing urinary tract infections (UTIs) by inhibiting bacterial adhesion to uroepithelial cells (proanthocyanidins). Duke notes the high vitamin C and organic acid content. Food-grade consumption is considered safe and beneficial as a urinary acidifier (Duke, 2002).

Botanical Description

Robust perennial herb with a basal rosette of coarse, hairy, lance-shaped leaves and tall, sturdy flowering stems. Each stem bears a single large, daisy-like flower head with drooping (reflexed), rose-purple to pink ray florets surrounding a prominent, spiny, orange-brown central cone of disc florets.[4]

Height: 60-150 cm
Habit: Robust, clump-forming perennial herb
Leaves: Coarse, hairy, lance-shaped, in a basal rosette
Flowers: Large daisy-like heads with drooping rose-purple ray florets around a spiny orange-brown cone
Stem: Tall, sturdy, hairy, mostly unbranched
Root: Thick, fibrous, black-brown taproot
Fruit: Small four-angled achene
Flowering Period: June-September

Low, creeping, evergreen dwarf shrub (Ericaceae) with slender, wiry stems that root at the nodes. Leaves are tiny, alternate, leathery and ovate with in-rolled margins, dark green above and whitish beneath. Flowers are small, pink and four-petalled, sharply reflexed backward so that the protruding stamens and style resemble a crane's head and neck - the origin of the name 'craneberry', later shortened to 'cranberry'. The fruit is a small, round, tart red berry.[8]

Height: Prostrate, mat-forming (stems trailing, rarely more than 10-20 cm above the moss)
Habit: Low, creeping, evergreen dwarf shrub
Leaves: Tiny, alternate, leathery, ovate, in-rolled margins, whitish beneath
Flowers: Small, pink, four-petalled, sharply reflexed (crane's-head shape)
Stem: Slender, wiry, trailing, rooting at the nodes
Root: Shallow fibrous roots adapted to waterlogged, acidic peat
Fruit: Small, round, tart red berry
Flowering Period: June-August

Habitat

Native to the tallgrass prairies, open woodland and dry meadows of central and eastern North America; widely cultivated worldwide as a garden and medicinal plant.[4]

Native to boggy, acidic wetlands - sphagnum bogs and marshes - across northern and central Europe and northern Asia, requiring waterlogged, nutrient-poor, acidic peat soils.[8]

Harvesting

The flower heads are picked as they open, in summer; the root is dug in autumn from plants at least two to three years old, when its content of bioactive alkamides and caffeic acid derivatives is highest, then cleaned and dried.[4]

Parts: Flower, Root
Season: Flower in summer; root in autumn from mature plants

Berries are hand-picked or wet-harvested (traditionally by hand-raking the bog) in autumn once fully ripe and deep red.[8]

Parts: Fruit
Season: Autumn

Traditional Uses

Echinacea root was widely used by Native American peoples as a remedy for infections, wounds, snakebite and toothache, and entered nineteenth-century Eclectic medicine as a broad anti-infective. It remains best known today, in standardised aerial-part or root extracts, as a supportive remedy for preventing and shortening the common cold and supporting immune function.[1, 4]

Cranberry has a long northern-European and Native American tradition as a food and folk remedy for urinary complaints, valued for its tart, astringent, vitamin-C-rich fruit. Modern research on its proanthocyanidins supports a role in reducing bacterial adhesion in the urinary tract, consistent with the traditional use for cystitis and recurrent urinary tract infections.[2, 11]

Preparations

Standardised extract[1]

Fresh-pressed juice or standardised extract of the aerial parts or root, taken as tablets, drops or capsules at the first sign of a cold; the best-studied clinical form.

Juice[2]

Unsweetened juice, the traditional preparation used for urinary support.

Standardised extract capsule[2]

Proanthocyanidin-standardised extract, a concentrated form used in clinical trials for UTI prevention.

Dosage

Standardised extract[1]

Clinical trials for the common cold commonly use around 300-900 mg of standardised extract daily, started at the first sign of symptoms and continued for up to 7-10 days; continuous use beyond about 8 weeks is not recommended. Educational reference only, not a prescription.

Drug Class Interactions

Safety note[19]Caution
Drug Class: immunosuppressants
Mechanism: Echinacea can both stimulate immune activity and alter CYP3A/CYP1A2 enzymes, so it may reduce the effect or change the blood levels of immunosuppressant drugs such as ciclosporin and tacrolimus; use only under medical supervision after a transplant or with autoimmune therapy.
