DEF

Sesquiterpene from the essential oil of leaves of Ledum palustre, having a molar mass of 222.41 g/mol.

CONT

Despite its name, Labrador tea is not the wholesome beverage that tradition would have us believe. Brewed in hot water, the leaves produce a toxic chemical called ledol which, consumed in sufficient quantity, causes severe cramps and paralysis.

CONT

The cousin to wild rosemary, Labrador tea ("Ledum glandulosum" formerly "L. latifolium"), was used in the 17th and 18th centuries in Canada in brewing. In the United States "Ledum goenlandicum" (variety of "Ledum palustre") and "L. glandulosum" grow in swampy and wet places, especially the Pacific Northwest. Wild rosemary ("L.p.") contains a volutile oil, "ledum oil", with strong inebriating effects. The aromatic ledol (in "L.g.") is sedative and slightly narcotic and similar to camphor in that it can cause cerebral irritation in large amounts.
