Safety, Cautions & Contraindications

Safety note[12, 13, 14, 15, 16]Caution

Cardamom is generally considered safe for most people when used in culinary amounts. At medicinal doses (supplement form), rare side effects include mild gastrointestinal discomfort and allergic reactions. There are no well-documented serious drug interactions at culinary doses. Cardamom may mildly lower blood pressure — caution if combined with antihypertensive medications. Some sources suggest potential gallstone formation with very high doses, as cardamom may stimulate bile flow. Avoid therapeutic doses during pregnancy until more safety data are available; culinary use is considered safe. Allergy to other Zingiberaceae (ginger, turmeric) may indicate cross-reactivity risk (Korikanthimath and Hiremath, 2002).

Safety note[12, 13, 14, 15, 16, 17]Caution

Duke (2002) provides clinical support (score 2) for cardamom as a cholagogue, antiviral agent, and appetite stimulant. Commission E and the German PDR (PHR) approve it for loss of appetite and bronchitis (score 2). The essential oil shows antispasmodic and carminative activity. Dose: 1.5 g ground fruit or equivalent preparation three times daily. Duke rates cardamom as generally safe (++), with no significant contraindications at therapeutic doses (Duke, 2002).

Safety noteCaution

Very little is known about the safety of field scabious and there are no clinical data; avoid medicinal doses in pregnancy and breastfeeding and use only modest amounts.

Safety note[5]Info

Most pharmacological data come from closely related Caprifoliaceae (genus Knautia, Scabiosa, Dipsacus) rather than Knautia arvensis itself; apply to field scabious with caution.

Botanical Description

Large, rhizomatous perennial herb with tall, reed-like leafy stems (pseudostems) formed by overlapping leaf sheaths, arising from a stout underground rhizome. Small, pale flowers with a violet-veined white lip are borne on separate trailing panicles that grow along the ground from the base of the plant. The fruit is a small, ridged, pale green three-sided capsule (the cardamom pod) containing numerous dark, aromatic seeds.[1]

Height: 2-4 m (leafy stems)
Habit: Large, rhizomatous, reed-like perennial herb
Leaves: Long, lance-shaped, glossy, arranged on tall leafy pseudostems
Flowers: Small, pale, with a violet-veined white lip, on trailing panicles near the ground
Stem: Tall, reed-like leafy pseudostems; flowering panicles trail separately along the ground
Root: Stout underground rhizome
Fruit: Small, ridged, pale green three-sided capsule (pod) containing numerous dark aromatic seeds
Flowering Period: Varies with climate, often during the rainy season

A hairy perennial herb of the honeysuckle family (formerly Dipsacaceae), 25-100 cm tall, growing from a stout rootstock. The stems are roughly hairy and bear opposite leaves that are variable - the lower ones often lyre-shaped or pinnately lobed, the upper deeply cut. The flowers are massed into flat, domed pincushion heads about 3-4 cm across, lilac to bluish-violet, with the outer florets enlarged; the heads are carried on long stalks and, unlike true scabious (Scabiosa), the receptacle is hairy rather than scaly. It flowers through summer and is a favourite of bees and butterflies.[1]

Height: 25-100 cm
Habit: Hairy perennial herb from a stout rootstock
Leaves: Opposite, hairy; lower leaves lyre-shaped/pinnately lobed, upper deeply cut
Flowers: Lilac to bluish-violet florets in flat, domed pincushion heads 3-4 cm across, outer florets enlarged
Stem: Erect, roughly hairy, branched above
Root: Stout rootstock with fibrous roots
Fruit: A small hairy achene enclosed in an epicalyx
Flowering Period: July-September

Habitat

Native to the moist evergreen forests of the Western Ghats of southern India and Sri Lanka; cultivated in warm, humid, shaded tropical conditions, notably in India, Guatemala and Sri Lanka.[1]

Dry grassland, meadows, pastures, dry hills, roadside banks, field margins and open woods, on well-drained and often calcareous soils across Europe and into western Asia and parts of Africa. A characteristic plant of unimproved dry meadows.[1]

Harvesting

The unripe green pods are hand-picked just before full maturity, then carefully dried (traditionally in the shade or by gentle heat) to preserve the green colour and aromatic oil; the pods are typically used whole or the seeds removed and ground just before use.

Parts: Fruit, Seed

The flowering aerial parts (leaves, stems, flower heads) are gathered in summer while in flower and dried; the root is also used. Best cut from established plants in dry grassland.[1]

Parts: Aerial parts, Flower, Root
Season: Aerial parts in flower (July-September); root in autumn

Traditional Uses

Cardamom has a long Ayurvedic, Middle Eastern and Asian tradition as a warming digestive carminative for indigestion and bloating, a remedy for respiratory complaints such as asthma and bronchitis, and a valued spice for tea, coffee and cooking.[1]

Field scabious has a European folk-medicine reputation chiefly as a remedy for skin complaints - eczema, itching, scabies (the name 'scabious' comes from its use against 'the scab'), cuts and sores - taken internally as a 'blood purifier' (alterative/depurative) and applied externally as a wash or poultice. It has also been used for coughs and sore throats. The plant is rich in phenolic acids, flavonoids and saponins; the closely related genera Knautia, Scabiosa and Dipsacus in the honeysuckle family share this chemistry and a tradition of use in skin disease and inflammation.[3, 4]

Preparations

Infusion (crushed pod/seed)[1]

Crushed pods or seeds infused in hot water, or added to tea/coffee, as a traditional carminative digestive preparation.

Infusion[3]

The dried flowering herb infused as a tea traditionally taken as an alterative ('blood purifier') for skin complaints and for coughs.

Wash / poultice[4]

A strong infusion or the crushed herb applied externally to eczema, itching, cuts and sores (traditional).

Dosage

Ground fruit/seed[11]

The WHO monograph on Semen Cardamomi gives an average DAILY dosage of 1.5 g of the drug, or equivalent preparations; for tincture, a daily dosage equivalent to 12 g. Note the 1.5 g is a daily total, not a per-dose amount. Educational reference only, not a prescription.
