How to Identify

A herb that grows in swamps. It keeps growing from year to year. It grows 30-60 cm tall. The leaves are pale green and 30-40 cm wide and up to 1.2 m long. The flowers are greenish purple. They have a greenish yellow spadix 5-10 cm long. They have a purple spathe around them. The flower can give off an unpleasant smell.

How to Grow

Plants can be grown from fresh seed sown into mud.

Propagation: Sow seed as soon as it is ripe in a cold frame for best results. If not sown immediately, store seed in water. Stored seed can be sown in late winter or early spring. Stand the pot in 2cm of water to keep the compost consistently wet. Seedlings should germinate in spring; prick out into individual pots once large enough to handle and grow on in wet soil in light shade in the greenhouse for at least the first winter. Plant out in late spring once large enough. Division can be done with great care while the plant is dormant.

Medicinal Uses

Skunk cabbage was widely used by native North American peoples, primarily for its expectorant and antispasmodic properties in treating bronchitis and asthmatic conditions — a use that continues in modern herbalism, though the plant should be used with caution and preferably under professional supervision. Handling fresh leaves can cause the skin to blister, and excessive doses of the root can cause nausea, vomiting, headaches, and dizziness. The root is antispasmodic, diaphoretic, diuretic, emetic, expectorant, and slightly narcotic. The rootstock is harvested in late autumn or early spring and dried for later use; it should not be stored for long as it loses medicinal potency. Internally, it has been used for respiratory and nervous disorders including asthma, whooping cough, catarrh, bronchitis, and hay fever, and occasionally for epilepsy, headaches, vertigo, and rheumatic problems. Externally, it has been applied as a poultice to draw out splinters and thorns, heal wounds, and treat headaches. Root hairs or rootlets have been placed in dental cavities to relieve toothache, and a tea made from root hairs has been used externally to stop bleeding. Crushed leaves have been inhaled to treat headaches, and leaf bases applied as a wet dressing to bruises.

Other Uses

An infusion of the powdered root has been used as a wash to eliminate strong body odour from under the arms.

Symplocarpus foetidus, commonly known as skunk cabbage or eastern skunk cabbage (also swamp cabbage, clumpfoot cabbage, or meadow cabbage, foetid pothos or polecat weed), is a low-growing plant that grows in wetlands and moist hill slopes of eastern North America. Bruised leaves present an odor reminiscent of skunk. Symplocarpus combines the Greek word symploce, meaning "connection" and carpos, meaning "fruit", to indicate that the plant has a compound fruit. Linnaeus gave the plant its species name of foetidus, Latin for "bad-smelling". The plant produces a strong odor, which is repulsive to many but sometimes described as smelling like "fresh cabbage with a slight suggestion of mustard". The odor increases in intensity over time, as the plant matures, likely due to increased ripeness in the plant's stamens.

Notes

It is used in medicine. There are 3 Symplocarpus species. It contains 5-hyrdoxy-tryptamine that can effect Serotonine absorption.
