Key Constituents
Seed essential oil dominated by 1,8-cineole and alpha-terpinyl acetate, giving the characteristic aroma and much of the carminative, antimicrobial and antioxidant activity.
Additional antioxidant constituents of the seed.
Phenolic monoterpenes responsible for the strong antimicrobial activity.
Antioxidant constituents.
Pharmacological Actions
Antimicrobial (antibacterial and antifungal via carvacrol and thymol) - supports respiratory and gastrointestinal infections; a small clinical study found emulsified oregano oil cleared enteric parasites (incl. Blastocystis hominis) and improved gut symptoms

Safety, Cautions & Contraindications
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).
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).
Culinary amounts are safe. Concentrated oregano essential oil is a strong irritant - dilute well before any topical use and do not take undiluted oil internally.
May lower blood sugar and has a mild antiplatelet effect, so use caution with antidiabetic or anticoagulant medicines; avoid medicinal/oil doses in pregnancy. Allergy is possible in people sensitive to the mint family (Lamiaceae).

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]
Perennial herb/subshrub (Lamiaceae), 20-80 cm tall, with square, often reddish, downy stems. Leaves are opposite, ovate and aromatic. Small purplish-pink (occasionally white) flowers are borne in dense, flattened, corymb-like clusters at the branch tips.[11]
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]
Native to the Mediterranean, Europe and temperate Asia and widely naturalised elsewhere, growing on dry, sunny grassland, banks and scrubby hillsides, typically on calcareous soils.[11]
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.
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]
Oregano has a long Mediterranean culinary-medicinal tradition as an aromatic digestive bitter and antiseptic remedy for coughs, colds and infections. Modern research on its carvacrol- and thymol-rich essential oil strongly supports broad antibacterial, antifungal and antioxidant activity, consistent with these traditional uses.[11, 12]
Preparations
Crushed pods or seeds infused in hot water, or added to tea/coffee, as a traditional carminative digestive preparation.
Dried herb steeped in hot water as a digestive, aromatic tea.
The most-studied form; concentrated oil is a strong irritant and must be well diluted before topical use and never taken undiluted internally.
A small clinical study used an emulsified oregano oil preparation to clear enteric parasites and improve gut symptoms; oral use of concentrated oil should be supervised.
Dosage
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.
Culinary amounts (as a food seasoning or mild tea) are considered safe; concentrated essential oil should only be used well diluted and is not intended for undiluted internal use without professional guidance. Educational reference only, not a prescription.
