Safety, Cautions & Contraindications

Safety note[10, 17]Caution

Avoid in pregnancy and when trying to conceive: high doses have shown reproductive toxicity in animals and the herb has a traditional reputation as an abortifacient.

Safety note[10]Caution

High doses have caused nephrotoxicity and reproductive toxicity in studies; use standardized products at recommended doses and avoid prolonged high-dose use.

Safety note[10, 17]Caution

May lower blood pressure and blood sugar and may interact with anticoagulant/antiplatelet, antihypertensive and immunosuppressant medicines; allergic reactions can occur.

Safety note[13, 14, 15]Caution

Generally very safe for topical use. May cause contact dermatitis in rare cases (Asteraceae family allergy). Internal use is safe in normal doses. Avoid during pregnancy at therapeutic doses (uterine stimulant potential). Generally safe during breastfeeding for topical use.

Safety note[13, 14, 15, 17]Info

Duke (2002) rates calendula (Calendula officinalis) and notes anti-inflammatory, wound-healing (vulnerary), antifungal, and antispasmodic activities at experimental levels. Commission E (KOM) approves calendula flower for wound healing and anti-inflammatory uses, both topically and as a gargle. The plant contains flavonoids, triterpene saponins (oleanolic acid glycosides), and essential oils. Dose: 1–2 g dried flower as tea (for mouth rinse/gargle); or as cream/ointment containing 2–5% calendula extract for topical use. Duke notes that calendula is generally very well-tolerated, though Asteraceae sensitivity can occasionally cause allergic reactions (Duke, 2002).

Botanical Description

Erect, branching annual herb with a slender, quadrangular (square-sectioned), dark green stem. The leaves are opposite, lance-shaped and glabrous, with a short stalk. Small, two-lipped, white flowers with purple-pink markings are borne in loose, spreading axillary and terminal racemes. The whole plant, and especially the leaves, is intensely and characteristically bitter.[11]

Height: 30-110 cm
Habit: Erect, branching annual herb
Leaves: Opposite, lance-shaped, glabrous, short-stalked
Flowers: Small, two-lipped, white flowers marked with purple-pink, in loose spreading racemes
Stem: Slender, quadrangular (square in cross-section), dark green, branching
Root: Shallow, fibrous root system
Fruit: Small, elastically dehiscent capsule
Flowering Period: September-December (varies by climate)

Aromatic annual or short-lived perennial herb with soft, hairy, oblong leaves and branching, slightly sticky stems. The flower heads are bright orange to yellow, daisy-like, with numerous narrow ray florets surrounding a darker central disc, opening in sunlight and closing at dusk.[1]

Height: 30-60 cm
Habit: Erect, branching annual or short-lived perennial herb
Leaves: Soft, hairy, oblong to lance-shaped
Flowers: Bright orange to yellow, daisy-like flower heads with numerous narrow ray florets
Stem: Branching, softly hairy, slightly sticky
Root: Shallow taproot
Fruit: Curved, ridged achene, without pappus
Flowering Period: June to first frost

Habitat

Native to India and Sri Lanka and widely distributed through South and Southeast Asia, growing wild in plains, hillsides, roadsides and cultivated fields; also grown commercially as a medicinal crop.[11]

Widely cultivated as a garden and medicinal plant; believed native to southern Europe and the Mediterranean, now naturalised in gardens and waste ground worldwide.[1]

Harvesting

The aerial parts (leaves and tender stems) are cut just before or at the onset of flowering, when andrographolide content is typically highest, and dried in shade to preserve the bitter diterpenoid lactones.[11]

Parts: Aerial parts (leaves and herb)
Season: Before to early flowering

The flower heads (or just the ray-floret petals) are picked by hand as they open, through the flowering season, and dried quickly in a warm, shaded, airy place to preserve colour and resin content.[1]

Parts: Flower, Petals
Season: Through the flowering season (summer to autumn), as flowers open

Traditional Uses

Andrographis, the 'king of bitters', is a cornerstone bitter tonic of Ayurvedic and traditional Chinese medicine (Chuan xin lian), used for fevers, colds, sore throat, infections and liver complaints. This traditional reputation for treating the common cold and upper respiratory infections is now supported by clinical trials of standardised extracts.[10, 12]

Calendula flower is one of the most widely used topical wound-healing and skin-soothing herbs in Western herbal medicine, applied to cuts, grazes, minor burns and skin inflammation, and used internally as a gentle anti-inflammatory and antimicrobial remedy and as a gargle for mouth and throat irritation.[1]

Preparations

Infusion/decoction[11]

Dried aerial parts infused or lightly decocted in hot water as a very bitter traditional fever and cold remedy.

Standardised extract[10, 12]

Extract standardised to andrographolide content, taken as tablets or capsules; the form used in most clinical trials for cold/URTI symptom relief.

Infused oil[1]

Dried petals infused in a carrier oil, used as a soothing base for topical creams and balms for skin healing.

Cream/ointment[1]

Standardised flower extract formulated into a cream or ointment for topical wound and skin care; the best-studied modern form.

Infusion[12]

Dried flower infused in hot water, 1-2 g in 150 ml, used still warm as a mouth rinse or gargle 2-4 times daily. The EU herbal monograph's posology for this preparation is OROMUCOSAL only - it does not support taking the infusion internally. Educational reference only, not a prescription.

Dosage

Standardised extract[10, 12]

Clinical trials for upper respiratory infection commonly use extracts standardised to around 60-120 mg andrographolide daily, in divided doses, for up to 5-7 days. Educational reference only, not a prescription.

Dried herb[13]

The WHO monograph on Herba Andrographidis gives, by indication - for the common cold, 1.5-3.0 g of the powdered crude drug three times daily, after meals and at bedtime; for pyrexia, a decoction from 3 g of the crude drug twice daily; for diarrhoea, a decoction from 3-9 g as a single dose as needed, or two 500 mg tablets four times daily. Note that the EMA HMPC assessed this herb and issued a public statement rather than a monograph, so there is no EU posology. Educational reference only, not a prescription.

Topical cream/ointment[12]

The EU herbal monograph gives semi-solid preparations containing the equivalent of 2-10% herbal substance, applied as a thin layer to the affected area 2 to 4 times daily. Educational reference only, not a prescription.

Infusion/gargle[12]

The EU herbal monograph gives 1-2 g of the flower in 150 mL water as an infusion, used still warm for rinsing and gargling 2 to 4 times daily, or to prepare impregnated dressings for the skin. This is an oromucosal and cutaneous preparation, not an oral tea. Educational reference only, not a prescription.
