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.
Gives the leaf its characteristic sour taste; the basis for the caution around kidney stones and mineral absorption at high intakes.
Minor constituents typical of the Rumex genus, studied alongside other isolated compounds for antibacterial activity against Helicobacter pylori.
The basis for the plant's traditional antiscorbutic (anti-scurvy) reputation.

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).
High in oxalates (the sour taste): Large, frequent amounts can be a bad idea if you’re prone to kidney or bladder stones, or certain “rheumatic-type” complaints (Royal Botanic Gardens, Kew, n.d.). Moderation matters: Measured oxalate levels in leaves can be high, and researchers recommend treating sorrel more like an occasional delicacy than a daily staple (Tuazon-Nartea & Savage, 2013). Mineral binding: Oxalic acid can reduce how much calcium you absorb from a meal (Tuazon-Nartea & Savage, 2013). Sensitive stomach/mouth: Very sour leaves can irritate some people (common-sense caution; strongest source is the oxalate discussion above). Pregnancy/lactation: As a normal food herb in culinary amounts is generally considered fine, but avoid high-dose “medicinal” use because safety data are limited (Bello et al., 2019). Foraging safety (important): Sorrel can accumulate heavy metals depending on where it grows; avoid harvesting near roads/industrial areas (Gawęda, 2009).
Duke (2002) rates sorrel as ++ and notes diuretic, antiscorbutic (high vitamin C), and depurative activities at experimental and folkloric levels. The plant is traditionally used for anemia, fever, and scurvy prevention. High oxalic acid content is an important consideration — excessive consumption can promote kidney stone formation (oxalate stones) and may be harmful in individuals with gout or existing kidney disease. Duke advises limiting medicinal use and avoiding in those with a history of calcium oxalate kidney stones (Duke, 2002).

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 (Polygonaceae), 30-100 cm tall, with erect, often reddish, ridged flowering stems. Basal leaves are arrow- (hastate-) shaped with backward-pointing basal lobes, and sour-tasting from oxalic acid content. Tiny reddish-brown flowers are borne in narrow, branched spikes; the species is dioecious, with separate male and female plants.[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 throughout Europe and temperate Asia, common in meadows, grassland, pastures and roadside verges on a wide range of soils, tolerating both damp and dry ground.[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.
Leaves are gathered fresh in spring and early summer, before flowering, when they are most tender and least bitter. Avoid harvesting near roads or industrial areas, given the plant's tendency to accumulate heavy metals.[11]
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]
Common sorrel has a long European culinary-medicinal tradition as a refreshing, vitamin-C-rich spring green and digestive bitter, and folk-medicinally as a diuretic and mild antiscorbutic (anti-scurvy) remedy. Modern research confirms antioxidant, anti-inflammatory and antimicrobial activity of its leaf extracts.[11]
Preparations
Crushed pods or seeds infused in hot water, or added to tea/coffee, as a traditional carminative digestive preparation.
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.
Sorrel is best treated as an occasional food rather than a daily medicinal herb, given its oxalate content; traditional infusions use roughly 2-4 g dried leaf per cup, taken occasionally rather than regularly. Educational reference only, not a prescription; avoid large or frequent amounts if prone to kidney stones or gout.
