Key Constituents

Alkamides[4]

Lipophilic alkamides are considered key immunomodulatory and anti-inflammatory constituents, particularly concentrated in the root.

Caffeic acid derivatives (echinacoside, cichoric acid)[4]

Antioxidant phenolic compounds contributing to the plant's immunomodulatory activity.

Caffeic acidPhenolic acids
Polysaccharides[4]

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

Polysaccharides
Essential oil (thymol, carvacrol, p-cymene)[2]

The volatile oil, dominated by thymol and carvacrol, gives most of the antimicrobial and antioxidant activity.

Phenolic acids and flavonoids (rosmarinic acid, luteolin)[3]

Contribute additional antioxidant activity.

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]Caution

Generally safe at culinary doses. Essential oil is highly concentrated and must be diluted before topical use; undiluted application can cause skin sensitisation. Not recommended internally during pregnancy (uterine stimulant effects possible). Phenol-rich thyme preparations should be avoided long-term in high doses. May potentiate anticoagulant medications.

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

Duke (2002) rates Thymus vulgaris (garden thyme, closely related to breckland thyme) as +++ with clinical evidence (score 2) for antibacterial, bronchospasmolytic, and antispasmodic activities, consistent with Commission E and WHO approvals for bronchitis and upper respiratory catarrh. The primary active constituent is thymol, with carvacrol as a secondary compound. Dose: 1–2 g dried herb as tea three times daily. The plant demonstrates COX-2 inhibitory activity and calcium antagonism, which may explain its antispasmodic effects (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, mat-forming, aromatic perennial subshrub with tiny, oval, strongly aromatic leaves on trailing, wiry, hairy stems that root as they spread. Small, pinkish-purple, two-lipped flowers are borne in dense whorled clusters at the stem tips.

Height: 2-10 cm (mat-forming, trailing)
Habit: Low, mat-forming, aromatic perennial subshrub
Leaves: Tiny, oval, strongly aromatic
Flowers: Small, pinkish-purple, two-lipped, in dense whorled terminal clusters
Stem: Trailing, wiry, hairy, rooting as it spreads
Root: Fine, fibrous roots along the creeping stem
Fruit: Small nutlet
Flowering Period: May-September

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]

Grows on dry, sunny heath, grassland, rocky ground and sandy soils; native to Europe and widely distributed across the northern temperate zone.

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

The flowering aerial parts (flower and leaf) are cut at the start of flowering in summer and dried in a warm, shaded, airy place.

Parts: Flower, Leaf
Season: Summer, at start of flowering

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]

Wild thyme has a long European folk tradition, closely paralleling its relative garden thyme, as an antimicrobial and expectorant remedy for coughs and respiratory infections, a digestive/gastroprotective herb, and a topical antiseptic.[11, 12, 13]

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.

Infusion[12]

Dried flowering herb infused in hot water as a traditional respiratory and digestive tea.

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.
