Symplocarpus foetidus
Pronounced Skunk Cabbage: SKUHNGK KAB-ij. Symplocarpus foetidus: sim-ploh-KAR-pus FET-ih-dus (also fee-TID-us).
Warm, dry, and acrid: a stimulating, relaxing antispasmodic expectorant that loosens bronchial and nervous spasm and moves cold, stagnant phlegm from a tense, constricted, congested chest.
Avoid in pregnancy. Modern references classify skunk cabbage as possibly unsafe: WebMD, drawing on Brinker's Herb Contraindications and Drug Interactions (2nd ed., 1998) and the AHPA Botanical Safety Handbook (1997), states that it 'is possibly unsafe to use skunk cabbage while pregnant. It might affect the menstrual cycle or cause the uterus to contract, which might lead to a miscarriage.' This reputed emmenagogue and uterine-stimulant action, together with the irritant calcium-oxalate content, makes avoidance the prudent, consumer-safe course throughout pregnancy.
Avoid during breastfeeding. WebMD (per Brinker and the AHPA Botanical Safety Handbook) rates skunk cabbage as possibly unsafe while breastfeeding, and there is no reliable human safety data on transfer of its acrid constituents into breast milk. Given the calcium-oxalate acridity and the absence of lactation safety data, avoid therapeutic use while nursing.
Not recommended for children. There is no established pediatric dosing and no modern pediatric safety data. The acrid calcium-oxalate raphides make even small amounts of poorly prepared or raw material capable of causing intense mouth and throat pain and dangerous airway swelling, a particular hazard in small children. Reserve any use to qualified practitioner supervision, and treat childhood asthma and whooping cough as conditions requiring medical care rather than self-directed herbal dosing.
Skunk cabbage is an acrid, low-margin herb and is not for casual self-dosing. The fresh plant and root are intensely acrid from calcium-oxalate raphides: even small amounts of the raw plant can cause intense burning of the mouth and throat and swelling that can threaten the airway, and the fresh material can burn and blister the skin. Larger medicinal doses may cause nausea, vomiting, diarrhea, headache, and dizziness (WebMD). Because it contains calcium oxalate, it can irritate the kidneys and may raise the risk of kidney stones, so it is best avoided by those prone to oxalate stones. Its acridity can worsen inflammatory and ulcerative gut conditions (peptic ulcer, ulcerative colitis, Crohn's disease). The dried root loses potency on keeping, so preparations vary widely in strength. Use only well-prepared, correctly dosed material, ideally under a knowledgeable practitioner.
Pregnancy (possible emmenagogue and uterine-stimulant action with miscarriage risk, plus acrid oxalate irritancy) and breastfeeding. Known oxalate kidney-stone disease or oxalate nephropathy. Active peptic ulcer, ulcerative colitis, or Crohn's disease (acrid irritant). Ingestion of the raw or fresh plant in any quantity (oropharyngeal burning and airway swelling from calcium-oxalate raphides). Hot, dry, inflamed respiratory states (dry irritable cough, phlegm-heat). Known hypersensitivity to skunk cabbage or other Araceae.
Symplocarpus foetidus is a common, widespread native perennial of eastern North American wetlands and is not listed as at-risk by United Plant Savers. It is, however, a slow-growing, long-lived wetland plant with deep contractile roots, tied to sensitive swamp and seep habitats that are themselves under pressure from drainage and development. Harvest thoughtfully and sparingly, avoid disturbing intact wetlands, and prefer ethically wildcrafted or cultivated root; because the plant anchors wet-woodland ecosystems and hosts early pollinators, leave established colonies undisturbed.
Not found in the canonical biblical texts nor in the classical Greco-Roman herbals of Dioscorides and Pliny; skunk cabbage is a plant of eastern North America (and northeast Asia), unknown to the ancient Mediterranean world. Its documented medicinal tradition is Native American (Winnebago, Dakota, and Iroquois use of the root as an expectorant and antispasmodic) and nineteenth-century Eclectic-American, where it was the officinal drug 'Dracontium.' Cited honestly as an herb of North American, not biblical, tradition.
