Key Constituents
The intensely bitter principles that stimulate digestive secretions.
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.
Pharmacological Actions
Digestive aid for mild dyspeptic complaints such as indigestion and bloating (stimulates gastric and bile secretion) - a comprehensive review also documents gastroprotective, hepatoprotective and anti-inflammatory activity
Aromatic bitter tonic for temporary loss of appetite

Safety, Cautions & Contraindications
Because bitters increase stomach-acid secretion, centaury is contraindicated in peptic (stomach or duodenal) ulcer disease and hyperacidity.
Traditional use only; appetite loss or dyspepsia that persists needs medical assessment. Use during pregnancy and breastfeeding is not recommended.
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).

Botanical Description
Slender annual or biennial herb with a basal rosette of oval leaves and an erect, wiry, four-angled flowering stem branching near the top. Small, star-shaped, pink flowers with five pointed petals open only in sunshine, borne in dense, flat-topped clusters at the stem tips.[12]
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]
Habitat
Grows in dry grassland, chalk downland, dunes and open woodland on well-drained, often calcareous soils; native to Europe, North Africa and Western Asia.[12]
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]
Harvesting
The flowering aerial parts are cut in summer while in flower, when the intensely bitter secoiridoid content is highest, and dried in a warm, shaded, airy place.[12]
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
Centaury is one of the classic European bitter digestive herbs, traditionally used for temporary loss of appetite and mild dyspeptic complaints such as indigestion and bloating, stimulating gastric and bile secretion.[12]
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]
Preparations
Dried herb macerated in cold water for several hours, which extracts the bitter principles while minimising extraction of harsher tannins; a traditional preparation method for bitters.
Dried herb infused briefly in hot water and taken shortly before meals as a bitter digestive tonic.
Tincture of the dried herb; the EU herbal monograph gives 1.5-5 g up to three times daily. Educational reference only, not a prescription.
Crushed pods or seeds infused in hot water, or added to tea/coffee, as a traditional carminative digestive preparation.
Dosage
The EU herbal monograph gives 1-4 g of the comminuted herb in 200 mL of boiling water as an infusion, up to 4 times daily, in adults and elderly; a powdered herbal substance at 0.25-2 g up to 3 times daily, liquid extract 2-4 mL up to 3 times daily, and tincture 1.5-5 g up to 3 times daily are also listed. Not recommended under 18 years, and contraindicated in peptic ulcer. Educational reference only, not a prescription.
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.
