Safety, Cautions & Contraindications

Safety noteCaution

Peach-leaved bellflower is chiefly an edible and ornamental plant, and very little is known about medicinal use or safety of the species specifically; there are no clinical data. Use culinary amounts, and avoid medicinal doses in pregnancy and breastfeeding.

Safety note[1]Info

The pharmacological data here are for the genus Campanula and related bellflower species, not for Campanula persicifolia itself; interpret with caution.

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).

Botanical Description

An elegant perennial herb of the bellflower family, 30-90 cm tall, growing from a slender rhizome. It forms an overwintering rosette of narrow, leathery, finely-toothed leaves that resemble those of a peach tree (hence 'peach-leaved'); the few stem leaves are similar but smaller. The large, broad, open bell-shaped flowers - about 3-4 cm across, clear blue to lilac or white - are borne in a loose, one-sided spike in summer. Like other bellflowers it exudes a white latex when cut. It is widely grown as an ornamental garden perennial, and its young leaves and roots have historically been eaten.[1]

Height: 30-90 cm
Habit: Slender rhizomatous perennial with an evergreen leaf rosette
Leaves: Narrow, leathery, finely toothed, peach-leaf-like; mostly in a basal rosette
Flowers: Large, broad, open bells (3-4 cm), clear blue to lilac or white, in a loose one-sided spike
Stem: Erect, slender, little-branched, exuding white latex when cut
Root: Slender rhizome with fibrous roots
Fruit: A nodding capsule opening by pores near the top
Flowering Period: June-August

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

Habitat

Open woodland, wood margins, scrub, hedge banks and dry to moist grassland across much of Europe and into western Asia; also very widely cultivated and naturalised as a garden ornamental. It favours well-drained soils in sun or light shade.[1]

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]

Harvesting

Young leaves and shoots are gathered in spring for use as a salad or pot-herb (mild, faintly sweet, like other bellflowers and rampion); the flowers are gathered in summer, and the root can be dug in autumn. Chiefly a food and ornamental plant rather than a medicinal drug.[5]

Parts: Leaf, Flower, Root
Season: Young leaves/shoots in spring; flowers in summer; root in autumn

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

Traditional Uses

Peach-leaved bellflower is primarily an edible and ornamental plant rather than a classical medicinal herb: its young leaves and roots have long been eaten as a wild salad green or pot-herb, in the same way as its relative rampion (Campanula rapunculus). Folk use of bellflowers (Campanula) includes a leaf or flower infusion as a gentle gargle and wash for sore throat and mouth inflammation, and topical use of the crushed herb on inflamed skin. More broadly, the genus Campanula has traditional records of use for inflammatory, respiratory and cardiovascular complaints, backed by its phenolic, flavonoid and triterpene chemistry.[1, 5]

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]

Preparations

Salad green / pot-herb[5]

Young leaves and shoots eaten raw in salads or lightly cooked as a mild pot-herb; the root is also edible (as with rampion bellflower).

Infusion / gargle[1]

A leaf or flower infusion used traditionally as a gentle gargle and wash for sore throat and mouth inflammation.

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.

Dosage

Not documented

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

Not documented

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.
