Habitat: Native to North America, Europe and Asia.
English: Bearberry.Unani: Inbud-dub, Angur-e-khiras, Reechh Daakh.Action: Astringent, dirutic; used for urinary tract infections, dysuria, cystitis, urethritis, pyelitis.
The leaves gave 0.8-1% of a flavanol glucoside, isoquercitin, arbutin and methyl arbutin. Total arbutin content varies from 7.5 to 10.7%; tannins 15 to 20%. Arbutin hydrolyses to hydro- quinone, a urinary antiseptic.Arbutin is antimicrobial, but the crude extract of uva-ursi is more effective than isolated arbutin. In rats, uva- ursi showed anti-inflammatory activity against experimentally induced inflammation.

English: Fragrant Wintergreen, Indian Wintergreen. (Wintergreen oil is obtained from G. procumbens Linn., a native of America.)Ayurvedic: Gandhapuura, Gandha- puurna.Siddha/Tamil: Kolakkaai.Action: Leaves—stimulant, carminative, diuretic, antiseptic. Oil (in the form of liniment or ointment)— applied externally in rheumatism, sciatica and neuralgia. The plant is strongly irritant.
The leaves gave hyperoside (quer- cetin-3-galactoside), ursolic acid, beta- sitosterol and essential oil containing methyl salicylate as a major constituent. The yield of oil from Assam plants contains 99.14% methyl salicy- late. Heptyl aldehyde, present in the low boiling fraction of the oil, brought about the regression of tumours in mice and dogs.... gaultheria fragrantissimaHabitat: Outer Himalayas from Kashmir to Sikkim, at 1,000 to 2,500 m, and in Khasi hills between 1,200 to 2,000 m.
Folk: Angyaar (Garhwal), Arwan (Punjab), Angeri (Nepal).Action: Young leaves and buds— used externally for cutaneous affections. Leaves—insectici- dal. Honey from flowers— poisonous.
Leaves contain a toxic, insecticidal substance andromedotoxin.The wood yields 0.51% ash, rich in soluble potassium salts.... lyonia ovalifoliaHabitat: The temperate Himalayas from Kashmir to Bhutan, the Nilgiris, Khasi Hills and Travancore.
English: Tree-Rhododendron, Rose-Tree.Folk: Burans (Kumaon), Kurbak, Pullaas.Action: Leaf—anticephalalgic (applied to the forehead). Leaf and stem-bark—spasmolytic. Flowers— used in diarrhoea and dysentery.
The green leaves contain a gluco- side, ericolin. The extracts of leaves, stems and bark cause hypotension in cats and inhibit intestinal movements in rabbits. The acetone and chloroform extracts and a resinous fraction from the alcoholic extract of leaves depress respiration. The petroleum ether extract decreases the rate of heartbeat and contraction in isolated heart of frog.An alcoholic (50%) extract of the flowers lowered blood pressure in dogs and albino rats.Cyanidin-3-galactoside and cyani- din-3-arbinoside are present in the pigments of flowers. The leaves of var. nilgiricum and var. cinnamonum contain ursolic acid, friedelin, epifrie- delanol, quercetin. A triterpenoid, campanulin, has been isolated from the leaves of var. nilagaricum.... rhododendron arboreumFamily: Ericaceae.
Habitat: The Himalayas from Kumaon to Bhutan, extending to Assam.
English: Giantblood Rhododendron.Folk: Chimal (Nepal), Kurbak, Guraans.Action: Respiratory depressant, emetic, toxic.
The leaves and flowers gave an- dromedotoxin which resembles tertiary amine veratrum alkaloids, particularly protoveratrine, in pharmacological action. Intravenous administration of andromedotoxin to dogs resulted in 20-40% reduction in blood pressure. It also closely resembles protoveratrine in its stimulating effect on the barostatic-pressor-reflex- mechanism, respiratory effects and emetic action. It produces reflex va- sodepressor responses in intact animals; in debuffered dogs, it produced vasopressor responses. It also produced, both direct and indirect, positive ionotropic effects, the latter being more pronounced.The leaves contain ursolic acid, alpha-amyrin, epi-friedelinol, cam- panulin and hyperoside. Chloroform extract of the leaves and shoots showed a depressant action. The honey from flowers is poisonous; contains an- dromedotoxin.... rhododendron barbatumHabitat: Throughout the Himalayas at altitudes of 2,400-5,200 m.
Folk: Chimal (Kumaon, Nepal), Gagger vurmi, Nichnai (Kashmir). Cherailu, Taalis-far.Action: Leaves—used in chronic rheumatism and sciatica. As a snuff, in colds and hemicrania.
The leaves gave a toxic substance which resembles andromedotoxin; besides ericolin, ursolic acid, alpha-amy- rin, friedelin, epi-friedelinol, campan- ulin, quercitin. The pigments of flowers contain myricetin and quercetin.Petroleum ether and chloroform extracts of leaves, stems and flowers lower blood pressure in cats and inhibit intestinal movements in rabbits.... rhododendron campanulatumHabitat: Eastern Himalayas, extending into the Balipura tract and Aka hills of Assam at altitudes of 2,100-4,000 m.
Folk: Balu, Sanu, Chimal (Nepal).Action: Plant—vasodepressor.
The plant contains a toxic principle, andromedotoxin. The leaves are reported to contain friedelin, epi- friedelinol, alpha-amyrin, campanulin, ursolic acid, triterpenes and quercetin.The flowers are reported to be poisonous.R.falconeri Hook. f., known as Ko- rlinga in Nepal, Kegu and Kalma in Bhutan, is found in the Himalayas from Nepal to Bhutan, Aka Hills, Naga Hills and Manipur at altitudes of 2,1004,300 m.The leaves and stem contain an- dromedotoxin; leaves also contain ur- solic acid, alpha-amyrin, friedelin, campanulin and quercetin. The flowers contain 3-rhamnoside and 3-galacto- side of quercetin. The bark gave taraxe- rol, betulinic acid and quercetin.Petroleum ether extract of the leaves and stems lowers blood pressure in cats and inhibits intestinal movements in rabbits.... rhododendron cinnabarinumFAMILY: Ericaceae
SYNONYMS: Aromatic wintergreen, checkerberry, teaberry, gaultheria (oil).
GENERAL DESCRIPTION: A small evergreen herb up to 15 cm high with slender creeping stems shooting forth erect twigs with leathery serrated leaves and drooping white flowers, which are followed by fleshy scarlet berries.
DISTRIBUTION: Native to North America, especially the north eastern region and Canada. The oil is produced in the USA.
OTHER SPECIES: There are several other Gaultheria species which are also used for oil production, sharing similar properties.
HERBAL/FOLK TRADITION: The plant has been used for respiratory conditions such as chronic mucous discharge, but is mainly employed for joint and muscular problems such as lumbago, sciatica, neuralgia, myalgia, etc. The dried leaf and stem are current in the British Herbal Pharmacopoeia as a specific for rheumatoid arthritis.
The essential oil has been used interchangeably with sweet birch oil, both being made up almost exclusively of methyl salicylate.
ACTIONS: Analgesic (mild), anti-inflammatory, antirheumatic, antitussive, astringent, carminative, diuretic, emmenagogue, galactagogue, stimulant.
EXTRACTION: Essential oil by steam (or water) distillation from the leaf, previously macerated in warm water. The essential oil does not occur crudely in the plant, but is only produced during the process of decomposition in warm water.
CHARACTERISTICS: A pale yellow or pinkish liquid with an intense sweet-woody, almost fruity odour. It blends well with oregano, mints, thyme, ylang ylang, narcissus and vanilla.
PRINCIPAL CONSTITUENTS: Almost exclusively methyl salicylate (up to 98 per cent), with formaldehyde and gaultheriline.
SAFETY DATA: Toxic, irritant and sensitizing – an environmental hazard or marine pollutant. The true oil is almost obsolete, having been replaced by synthetic methyl salicylate. See also sweet birch oil.
AROMATHERAPY/HOME: USE None. ‘Avoid both internally and externally.’.
OTHER USES: Some pharmaceutical use, such as ‘Olbas’ oil. Some perfumery applications especially in forest-type fragrances. Extensively used as a flavouring agent in the USA for toothpaste, chewing gum, root beer, Coca-Cola, and other soft drinks.... wintergreen
FAMILY: Ericaceae
SYNONYMS: Ledum, Labrador tea, marsh tea, swamp tea, bog Labrador tea, rusty Labrador tea, Hudson’s Bay tea (formerly Ledum groenlandicum).
GENERAL DESCRIPTION: This beautiful, hardy plant is a shrub belonging to the heather family, which can reach one metre in height. It is recognizable by its thick, leathery evergreen leaves whose edges coil under and are quite unique, being deep green on top with a downy-fuzz beneath. New leaves have a woolly mat of white hairs underneath; mature leaves have reddish hairs. All leaves are dotted with resinous glands and are fragrant, with a pungent scent, when crushed. The fluffy white flowers, which are borne in spring, are also strongly aromatic.
DISTRIBUTION: The plant is native to North America, from Greenland and Labrador across to Alaska, as far north as the treeline. It is absent from the far North and the dry prairies. The Latin name groenlandicum refers to the fact that it grows in Greenland where it is still widespread, often growing in dense colonies.
OTHER SPECIES: Ledum is a genus name, which includes 8 species of evergreen shrubs native to cool temperate and sub-arctic regions of the Northern Hemisphere, commonly known as Labrador tea. The common name Ledum is also applied to Rhododendron tomentsum subsp. subarcticum (formerly L. decumbens) which is known as Northern Labrador tea. This species, which is similar but slightly smaller, grows farther north on tundra at up to 1,800 metres and contains toxic alkaloids known to be poisonous to livestock. It lacks the characteristic fuzz on the underside of the mature leaves and the flowers of L. groenlandicum.
HERBAL/FOLK TRADITION: This strongly aromatic herb has been used in folk medicine for centuries. Brewed as a medicinal beverage known as Labrador tea, it was used by practically all Canada’s First Nations peoples as a tonic and to treat certain respiratory, digestive and kidney ailments; as a remedy for headaches and various types of rheumatism; and to facilitate childbirth. The herbal tea also served to clean wounds and was applied to insect bites. It is said that the plant was used for over 5,000 years by the native people of North America, to protect themselves from scurvy, and the Cree used it for fevers and colds: indeed it was regarded as a ‘cure-all’ by the indigenous people. In the fur-trading era, the French Canadian coureurs-de-bois used Labrador tea to extend their supplies of black tea: it thus became a substitute for unaffordable Chinese tea during times of economic crisis. However, like other plants in the heather family, Greenland moss contains an andromedo-toxin that can cause poisoning if used in excess.
According to recent clinical trials, Greenland moss essential oil has a natural affinity for the immune system and can be an effective immune system supporter. The oil also helps counteract blood toxicity and aids liver regeneration, valuable in cases of liver intoxication originating from circulation disorders, viral hepatitis, enteritis and cirrhosis (fatty liver). Clinical research suggests that the essential oil functions like an enzyme in the liver, digesting toxic waste and fat molecules. It is also indicated for obesity, oedema, water retention and thyroid regulation. The oil has also been studied at the University of Quebec, and was found to be a strong antioxidant and natural anti-inflammatory: it also showed anticancer activity against colon carcinoma and lung carcinoma cells.
ACTIONS: Analgesic, antibacterial, anticancerous, antiviral, anti-inflammatory, anti-tumoral, antispasmodic, antioxidant, anti-infectious, antiseptic, carminative, cicatrizing, decongestant, digestive tonic, immune support, liver support, stomachic, tonic.
EXTRACTION: Greenland moss oil is extracted by steam distillation from the leaves.
CHARACTERISTICS: A clear, pale-yellow liquid, with a fresh-herbaceous, medicinal and slightly sweet aroma and earthy-woody undertones.
PRINCIPAL CONSTITUENTS: The main chemical constituents are limonene (up to 35 per cent), sabinene, selinene, bornyl acetate with other monoterpenes and sesquiterpenes.
SAFETY DATA: Possible skin sensitization: always dilute for topical use. Avoid during pregnancy and by children. NB: Abusive consumption of the tea derived from its leaves may cause indigestion, and may even have a toxic effect due to the high level of tannins that it contains.
