Ledum glandulosum Nutt. (61-84) Two varieties in B.C.: (287-345) (a) L. glandulosum Nutt. var columbianum (Piper) Hitchc. (287-345): Leaves strongly revolute, 3-5 x scarcely 1(1.5) cm; caps ovoid, 4-5.5 mm; RANGE: Pacific Co, Wn, South along coast to Marin Co, California (287-345); Syn: Ledum californicum, Ledum glandulosum ssp californicum, Ledum glandulosum ssp. californicum var. australe (287-345); (b) Ledum glandulosum var. glandulosum (287-345): Leaves plane or slightly revolute, 1.5-3 (4) cm, generally at least half as broad; (287-345); Caps subglobose, 1-3 (4.5) mm (287-345); British Columbia south, on the east side of the Cascades, to Wn, east in British Columbia to the Rocky Mountains, south to Montana and Northern Wyoming, west to central Idaho and northeast Oregon (287-345); OTHER LATIN NAMES: Ledum californicum Kell. (61-84); COMMON NAME: Glandular Labrador, Trapper's tea, Coastal Labrador Tea, Western Labrador tea (61-84); Labrador Team, Smooth Ledum, Mountain Ledum (287-345); DESCRIPTION: Stout, erect shrub, 0.5-1.5 m. tall, with twigs puberulent and minutely glandular. (61-84); LEAVES: Petiolate, elliptic to oval, up to 5 cm. long, green and rugose above, whitish-puberulent and resinous-granuliferous beneath, more or less revolute. (61-84); FLOWERS: White, in terminal raceme; pedicels up to 2 cm. long, puberulent and usually glandular; sepals ciliate on the margins; petals oblong, up to 8 mm. long; stamens 8-12 (usually 10), considerably longer than the style, densely hairy below the middle. Season is June to August. (61-84); FRUIT: Capsule, about 5 mm. long, globose to ovoid, puberulent and glandular (61-84); HABITAT: Wet mountain meadows and wet open woods on higher elevations (61-84); RANGE: British Columbia to California, eastward to the Rocky Mountains and southward to Wyoming; also in Idaho and Oregon (61-84); Restricted to the Southwest and Southeast Interior, where it is quite abundant locally and well defined in its distribution. (61-84); COMMENTS: Glandular labrador tea is easily separated from other specie, having leaves which are green and rugose above, pale greenish and densely glandular beneath. The leaves in other species are densely rusty-tomentose beneath. Young twigs are finely pubescent and glandular-dotted. Of apparent geographic significance is var. columbianum (Piere) C. L. Hitchc. (L. columbianum Piper), characterized by strongly revolute, narrow leaves, 3-5 cm. long and less than 1 cm. in width. This variety is rare with us, and the only specimen I have seen came from Vancouver, collected by J.K. Henry (1901). This record seems to be outside its range. The typical form, var. glandulosum, is rather a mountain plant and differs from var. columbianum by having entire or only slightly revolute leaves, about half as broad as they are long, and a distinctly globose capsule (61-86). 2. Ledum decumbens (Ait.) Lodd. OTHER LATIN NAMES: Ledum palustre var. decumbens Ait.(342-717); Ledum palustre var. angustifolium Herder, Ledum palustre subsp. decumbens (Ait.) Hult. (61-81, 342-717); Ledum decumbens (Ait) Small. (342-717) COMMON NAME: Northern Labrador Tea, Narrow-leaved labrador tea (61-83); DESCRIPTION: Similar to Ledum groenlandicum and the separating characters are confined mostly to the size of shrub, which in this species is much smaller (10-50 cm.), being more decumbent; leaves linear, which very seldom exceed 25 mm. in length and 3 mm. in width; stamens in most cases 10 in number, having filaments pubescent below the middle and much smaller fruit (capsule), only 3-4 mm. long. Other characters as in Ledum groenlandicum. (61-83); Low shrub, with brown, puberulent young twigs, glabrescent in age, flowers in umbel-like clusters; leaves linear, somewhat acute, with strongly revolute margin, shiny and glabrous above, cinnamon-brown, woolly beneath; pedicels rusty-puberulent; stamens mostly 10, hooked or curved at maturity; flowers white or pinkish (342-717); HABITAT: Limited to cold muskegs and bogs in lowland and alpine situations within its range. (61-83); Heaths, dry, rocky places, in the mountains to at least 1,800 meters; very common. Described from Hudson Bay (342-717); RANGE: Alaska, Yukon, through Northwest Territories to Labrador and Newfoundland and west Greenland, south to B.C., northern Manitoba. Eurasia. (61-83); COMMENTS: Ledum decumbens and Ledum groenlandicum are quite closely related to Ledum palustre L.; Hulten (1948) prefers to regard both of them as geographical races (subsp. of L. palustre). Undoubtedly there is a variation within these three populations and the relationships between them is still unclear.

(98-55); The leaves, crowded toward the tops of the twigs, are elongated, rounded with inrolled margins and densely fuzzy beneath. Young leaves are light green, pointing upward, with white fuzz beneath. In older leaves the blades are dark green to reddish, pointing groundwards, and the fuzz is rust-coloured. (103-145); The undersides of the leaves are pale and resinous-dotted and the margins are not rolled in." (8-23); FLOWERS: Flowers, many, in terminal racemes or corymbs, from large scaly buds, the new growth of the season originating at the base of the flower clusters.

(332-124); Covers miles of Marshland in European Russia, Siberia, and the Far East. (215-172) PLANT USES TOXICITY: - 1931 M. Grieve, A Modern Herbal, 460. "Of infusion, 2 to 4 fluid ounces three to four times a day. Overdoses may cause violent headache and symptoms of intoxication." (369-196, 141-460) - 1962 Adam Szczawinski, The Heather Family of B.C., 81. "All species have been reported as having a poisoning effect when browsed by animals, especially by sheep. As far as is known, the toxic principle appears to be andromedotoxin (a resinoid carbohydrate, 16-51). Since most of these plants have rather tough and bitter leaves, animals seldom eat them if more palatable forage is available." (61-81) - 1962 Adam Szczawinski, The Heather Family of B.C., 89. "The related species, L. glandulosum, is not suitable for making a beverage, and it is believed to have some poisonous effects." (61-89) - 1976 Lewis Clark, Wild Flowers of the Pacific Northwest, 380. "Ledol, a toxic compound that can induce cramps and paralysis has been isolated from the leaves of all of the ledum species. Possibly in the low concentrations of the pioneers' brew, this substance may have produced restorative effects similar to those resulting from caffeine in tea." (1-380) - 1977 John Tampion, Dangerous Plants, 107. "..All species of Kalmia, Ledum, Leucothoe, Menziesia, Pieris, Rhododendron, Lyonia, Andromeda, should be considered potentially toxic. Honey from Ericacean pollen is suspected of causing some human poisonings." (120-107) - 1983 Frantisek Stary, Poisonous Plants, 124. "All parts of the plant contain an aromatic, poisonous essential oil, although the leaves and flowers have the greatest concentration (0.5-3%). Its toxicity is due to the sesquiterpenic crystalline alcohol ledol and perhaps also palustrol. In recent years, doubts have been expressed as to the concentrations of the glycosides arbutin and ericolin generally given in the literature but this is not a determining factor in the plant's toxicity. Ledol has an irritant action and, taken internally, causes a state of excitement and intoxication at first, later vomiting, abdominal pains and severe diarrhoea. It also causes congestion of the lower pelvic region, has an irritant effect on the kidneys and urinary passages, and may cause miscarriage in pregnant women. Further symptoms, in the case of larger quantities, are muscular pains, giddiness, cramps and collapse." (332-124) - 1983 Frantisek Stary, Poisonous Plants, 124. "People are known to have been poisoned but, in animals, poisoning has been reported only in goats. Poisoning has ended in death for pregnant women who tried to abort the foetus by taking large doses of the extract from Wild Rosemary. Medicinal therapy used mainly galenical preparations from the crude drug (the dried flowering twigs or leaves): tinctures, infusions and, for external application, ointments. Ailments treated included rheumatic pains, whooping cough and inflammation of the upper respiratory passages. In folk medicine, Wild Rosemary is used externally to treat wounds (the essential oil has antiseptic properties), persistent eczemas and to destroy undesirable parasites." (332-124) - 1984 Canadian Pharmaceutical Association, Poison Management Manual, 44. "All of the plant parts (of andromedotoxin plants) contain the toxic principle andromedotoxin. Poisonings have occured in children from sucking on the flowers or drinking a "tea" made from the leaves. Ingestion of honey made from the nectar of rhododendron has also resulted in toxic effects. Fatalities have been reported from ingestion of sheep laurel (or lambkill) and Japanese pieris." (353-44) POISON SYMPTOMS: - 1982 Encyclopaedia Britannica, Volume 6, 955. "The poison causes watering of the mouth, eyes, and nose; vomiting; slow pulse; and depressed blood pressure. Massive ingestion of andromedotoxin results in convulsions and slow and progressive paralysis until death; fatalities, however, are rare." (EB 6-955) - 1984 Canadian Pharmaceutical Association, Poison Management Manual, 44. - Initial burning of mouth, tongue, and pharynx. - Systemic effects may be delayed for up to 6 hours after ingestion and include salivation, nausea, vomiting (may be severe), and diarrhea. - Drowsiness, headache, ataxia, muscle weakness; possible convulsions. - Generalized paresthesias may occur. - Hypotension, bradycardia; possible cardiac arrhythmias. - Respiratory depression. TREATMENT: - 1984 Canadian Pharmaceutical Association, Poison Management Manual, 44. " 1. Empty stomach if patient is not already vomiting. Follow with activated charcoal and a saline cathartic. 2. Maintain ventilation. Oxygen is required. 3. Monitor ECG, blood pressure. 4. Maintain fluid and electrolyte balance. 5. Hypotension unresponsive to fluid replacement may be treated with dopamine. 6. Atropine may be given to treat bradycardia. 7. Control excitation or convulsions with i.v. diazepam. CONSTITUENTS: - 1830 C.S. Rafinesque, Medical Flora or Manual of Medical Botany of the United States, Volume I, 236. "Contains 20 chemical substances, even wax and osmazome, very near to Chinese tea, but stronger, owing to fragrant resin. Leaves bitterish, nidorose (reeking) cephalic, pectoral, exanthemic, &c. Useful in coughs, exanthema, itch, scbies, leprosy &c. In strong decoction kills lice and insects. Said to be narcotic and phantastic by Schoepf." (369-195) - 1931 M. Grieve, A Modern Herbal, 460. "CONSTITUENTS: There has been found in the leaves tannin, gallic acid, a bitter substance, wax, resin, and salts." (141-460, 116-66) - 1931 M. Grieve, A Modern Herbal, 460. "Ledum palustre: The leaves contain a volatile oil, including 'ledum camphor', a stearopten, with valeric and volatile acids, ericolin, and ericinol. The tannin is called leditannic acid." (141-460) - 1978 Bradford Angier, Field Guide to Medicinal Wild Plants, 163. "Ledum palustre, according to a fairly recent U.S. Dispensatory, contains the glucoside ericolin, tannin, and valeric acid, among other things." (201-163) - 1981 Arnason, Hebda, & Johns, Use of Plants for Food and Medicine by Native Peoples of Eastern Canada, 2237. "Ledum groenlandicum Oeder.: LEAVES (100 grams of plant material): H2O (47.2 g), Protein (9.8 g), Ascorbic Acid (10 mg)." (435-2237) - 1987 Eleanor G. Viereck, Alaska's Wilderness Medicines, 44. "The tannin is called leditannic acid, and there are gallic acid (a bitter substance), wax, resin, salts, and ascorbic acid. Be warned that Labrador tea contains ledol, a poisonous substance causing cramps and paralysis. Grieve says the plant also contains a stearopten, valeric and volatile acids, ericolin, and ericinol." (407-44) FOOD USES: EUROPEAN FOOD USES: - 1795 Samuel Hearne, A Journey from Prince of Wales Fort in Hudson's Bay to the Northen Ocean in the Years 1769, 1770, 1771, and 1772. "It is, however, much used by the lower class of the Company's servants as tea; and by some is thought very pleasant. But the flower is by far the most delicate, and if gathered at the proper time, and carefully dried in the shade, will retain its flavour for many years and make a far more pleasant beverage than the leaves. There are several species of this plant, of which some of the leaves are nearly as large as that of the Creeping Willow, while others are as small and narrow as that of the Rosemary, and much resembles it in colour; but all the species have the same smell and flavour." (305-86) - 1823 Sir John Franklin, Narrative of a Journey. "Our only luxury (while navigating the Polar Sea in two canoes) now was a little salt, which had long been our substitute both for bread and vegetables. Since our departure from Point Lake we had boiled the Indian tea plant,'ledum palustre,' which produced a beverage in smell much resembling rhubarb; notwithstanding which we found it refreshing, and were gratified to see this plant flourishing abundantly, though of dwarfish growth, on the sea-shore." (131-Lab Tea) - 1888 Delamare Island of Miquelon transl. 25. "An infusion of the leaves is used in Saint-Pierre and Miquelon to replace tea and in Canada it is used to put a head on small beers." (369-195) - 1931 M. Grieve, A Modern Herbal, 460. "During the American War of Independence the leaves were much used instead of tea-leaves."(141-460, 116-66, 272-213) - 1931 M. Grieve, A Modern Herbal, 460. "They (the leaves) should be collected before flowering time, and the tops when the flowers begin to open. (141-460) - 1931 M. Grieve, A Modern Herbal, 460. "The leaves (of L. palustre) are reputed to be more powerful than those of L. latifolium, and to have in addition some narcotic properties, being used in Germany to make beer more intoxicating." (141-460) - 1972 Szczawinski & Hardy, Guide to Common Edible Plants of B.C., 23. "The leaves may be used as a tea substitute. The pungent aromatic taste is somewhat reduced if the leaves are steeped in one or two changes of boiling water. The addition of a few drops of lemon juice also improves the flavour." (8-23) - 1972 Dan & Nancy Jason, Some Useful Wild Plants, 65. "Labrador Tea leaves are best picked before flowering, then dried, crushed, and steeped for tea. They have a pleasant odour, spicy taste, and slightly narcotic properties." (12-65) - 1975 Dr. Triska, The Hamlyn Encyclopedia of Plants, 78. "During the middle ages Labrador tea was added to mead as a preservative. Towards the end of the 15th century it was used instead of hops in some areas." (119-78) - 1975 Russ Mohney, Why Wild Edibles, 126. "A dry mint leaf added per cupful as it steeps, changes its character to a noval, fragrant delight. Another interesting flavour departure is to drop just a few broken fir needles into the pot." (36-126) - 1977 Lee Allen Peterson, Edible Wild Plants, 208. "Tea. The dried leaves make a mild and agreeable tea when steeped for 5-10 minutes." (418-208) - 1977 Berglund & Bolsby, Edible Wild Plants, 170. "Pick Labrador tea leaves while the plant is flowering. Spread them on a shallow pan and dry in the oven on low heat. When dry, crush the leaves and store in an airtight container. To make tea, put 2 to 3 tablespoons of crumbled leaves into a preheated pot, pour boiling water over, and steep for five minutes before serving. The taste is not unlike Oriental tea, and it has a Vitamin C content." (168-170) - 1978 Turner & Szczawinski, Wild Coffee & Tea Substitutes of Canada #2, 57. "Labrador tea can be brewed in a number of ways. We think the best method is to place a generous handful of leaves in about 1 L (4 cups) of boiling water and allow them to simmer a short time, perhaps 5 minutes. The resulting tea has a yellowish-green tint and a sweet, flower-like fragrance reminiscent of jasmine tea. People who prefer it stronger leave it on the stove for several hours, but we do not recommend this procedure. A pleasant if somewhat weak beverage can be made simply by steeping the leaves in boiling water in a teapot, just as ordinary tea is made. You may find the flavour is enhanced by adding a few drops of lemon juice and a little honey. You can also use sugar and cream, but they tend to mask the delicate flavour." (98-57) - 1978 Turner & Szczawinski, Wild Coffee & Tea Substitutes of Canada #2, 55. "All species of L. palustre are suitable for making tea." (98-55) - 1978 Turner & Szczawinski, Wild Coffee & Tea Substitutes of Canada #2, 56. "Some people say that the leaves should be collected in the spring before the flowers appear; others declare that the best time for harvesting is in the fall or late winter, when the leaves are mature and reddish-brown in colour.

"In our experience, Labrador tea is as safe as regular tea or coffee, but it is said by some to produce drowsiness. We have never experienced such an effect, which may be due to physiological sensitivity in certain individuals or may in some cases be purely psychologial. In any case, we recommend that you drink the tea only in moderate quantities and in low concentrations; do not boil the leaves for longer than 10 minutes." (98-56) - 1982 Encyclopaedia Britannica, Volume 6, 955. "Humans can be poisoned by chewing on leaves and twigs or by sucking nectar from the flowers of these plants. Poisoned honey has been reported in areas in which bees visit large Rhododendron or laurel (Kalmia) stands, but the honey is so bitter that very little of it can be eaten."

"It is interesting to note that the Chippewa did not commonly drink water encountered in traveling but boiled it, making some of the following beverages from vegetable substances that were easily available. Fresh leaves were tied in a packet with a thin strip of basswood bark before being put in the water. Dried leaves could be used if fresh leaves were not available. The quantity was usually about a heaping handful to a quart of water. Beverages were usually sweetened with maple sugar and drunk while hot..Leaves of Labrador tea..354."

"INDIAN TEA: (Florence Burton, Kincolith) The Nishga people call their tea "tame-lock-lock-ock" which means "a place where there are only small branches around". This is a description of the locations that tea plants are usually found. The plant called Labrador tea or sometimes Hudson's Bay tea, is about ten inches high with small leaves that roll under at the edges. The leaves are picked from October to April, before the plant flowers. They are dried for a few days, then stored in a plastic bag for the winter. Prepare the tea with the following recipe: 1. In a 2 quart porcelain or stainless steel saucepan place 2 handfuls of dry tea leaves. 2. Fill the saucepan with cold water. 3. Simmer the tea on the stove for two hours then keep it hot on the back of the stove for the rest of the day. 4. The tea is served hot any time of the day. Indian tea has a sprucey flavour which may be improved with the addition of sugar." (160-51) - 1973 Turner & Bell, The Ethnobotany of the Southern Kwakiutl Indians, 283. "The KWAKIUTL, like all Northwest Coast groups, used the leaves of this bog plant for tea. About a handful of the leaves per quart of boiling water was used (Cranmer, 1969; Johnson, 1969). The leaves apparently have narcotic properties, but it is doubtful if the Indians were aware of this (Szczawinski & Hardy, 1962)." (150-283) - 1974 John Lust, The Herb Book, 523.

(195-523) - 1978 Nancy Turner, Food Plants of B.C. Indians, Part 2, 145. "As the various names of this shrub imply, the leaves were a common source of tea, not only in British Columbia, but across Canada. They were picked from August to April, depending on the traditions of the groups using them. Some, such as the OKANAGAN, picked the entire branch tips, twigs and all, whereas others used only the leaves. The SLAVE apparently used the flowers as well as, or instead of, the leaves, according to J.J. Honigmann (1946). Various recipes were used in different parts of the Province. A handful of fresh or dried leaves simmered in a quart of water for 15 minutes or more yields a pleasant drink, although some people like it stronger. It has a pleasant, aromatic fragrance and taste and is good with or without sugar. The leaves can also be added as a flavouring to regular tea or mint tea." (103-145) - 1978 Turner & Szczawinski, Wild Coffee & Tea Substitutes of Canada #2, 56.

The meat would be soaked in tea made from the boiled plant, or the meat, stems, and leaves would be boiled together." NOTE: Historical writings show that the pilgrims could have adopted the traditional Indian use of this plant and began brewing strong, flavourful tea that they judged to be nearly as good as the oriental varieties thay had in England.

"Labrador tea is common, widespread, and always available in northern climates where non-evergreen leaves are obtainable only during a short growing season. The plant also has a pleasant aromatic scent, lending a spicy fragrance to a tea. For these reasons it is perhaps no wonder this plant is mentioned in such a large number of ethnobotanical reports and herbal compendia. A small amount added to black tea does add a spicy aroma. It is used in this way on Nelson Island (Ager and Ager) or mixed with willow leaf tea (Lantis). Several authors (Tobe, de Laguna, Grieve) indicate that Labrador Tea is good for colds. The leaf tea is cathartic if it is strong enough to be orange-colored. The ascorbic acid content is second only to rosehips (Lantis)." (407-44) NATIVE MEDICINAL USES: - 1748 Henry Ellis A Voyage to Hudson's Bay. "The Plant, by the Indians called 'Wizzekapukka', is used by them, and the English as a Medicine, in nervous and scorbutick Disorders; its most apparent and immediate Effect, is promoting Digestion, and causing a keen Appetite.

(44-144) - 1982 Nancy Turner, Food Plants of B.C. Indian's, Part I, 144. "Various methods of collection and preparation of the leaves were used. For example, the HAIDA picked the young leaves in spring, before the plants flowered, although leaves could be harvested in summer from younger plants. The BELLA COOLA and MAINLAND COMOX, on the other hand, gathered the old reddish-brown leaves in late winter, just before the new leaves sprouted. The leaves were used fresh, or dried in the sun. The COMOX prepared them in a unique manner by steaming them in a shallow pit, and layers interspersed with licorice fern rhizomes, to flavour the tea. Water was added from time to time, through a hollow tube at the top, and the leaves were allowed to cook until they were dark brown. They were then placed in a plot of water and boiled to taste. The HAIDA perferred a dark coloured, strong tasting tea and often left a pot of it boiling on the stove for several days, adding more water as the liquid was depleted through use and evaporation.

"Hudson's Bay Tea (Ledum groenlandicum) and Swamp Laurel (Kalmia polifolia): These two common plants are closely associated in any of the muskeg areas of the Queen Charlotte lowlands near Masset. Most Masset Haida describe both plants by the name "xil kagann" although they carefully described the difference between the Ledum variety (leaves hanging down0 and Kalmia species (leaves pointing up). Collection of the leathery leaves which grow on these low shrubs is easily accomplished. The Leaves are allowed to air dry and are stored in jars or plastic bags today. Preparation for use is identical with both these plants and involves steeping the leaves in a pot of simmering rainwater, to make a tea. One woman stated that there was always a pot on the stove, "near the back", in her childhood home. Hudson's Bay tea is often used alone as a beverage. Some Haida people proudly referred to it as Indian tea. The tea is also used to treat influenza ("7il"), or the common cold ("tada"). The addition of swamp laurel leaves to the tea was reserved for clearly medicinal purposes. One woman stated that exactly forty branches with leaves, should be boiled in one gallon of rainwater all day, 'until the pitch shows up on the top of the water'.
