Mal: Nilaveppu, Kiriyattu Tam: Nilavempu Kan: KreataImportance: Kalmegh, the Great or Green Chiretta is a branched annual herb. It is useful in hyperdipsia, burning sensation, wounds, ulcers, chronic fever, malarial and intermittent fevers, inflammations, cough, bronchitis, skin diseases, leprosy, pruritis, intestinal worms, dyspepsia, flatulence, colic, diarrhoea, dysentery, haemorrhoids and vitiated conditions of pitta (Warrier et al, 1993). It is used to overcome sannipata type of fever, difficulty in breathing, hemopathy due to the morbidity of kapha and pitta, burning sensation, cough, oedema, thirst, skin diseases, fever, ulcer and worms. It is also useful in acidity and liver complaints (Aiyer and Kolammal, 1962). The important preparations using the drug are Tiktakagheta, Gorocandi gulika, Candanasava, Panchatiktam kasaya, etc. (Sivarajan et al, 1994). A preparation called “Alui” is prepared by mixing powdered cumin (Cuminium cyminum) and large cardamom (Amomum subulatum) in the juice of this plant and administered for the treatment of malaria (Thakur et al, 1989). It is also a rich source of minerals.Distribution: The plant is distributed throughout the tropics. It is found in the plains of India from U.P to Assam, M.P., A.P, Tamil Nadu and Kerala, also cultivated in gardens.Botany: Andrographis paniculata (Burm.f.) Wall ex.Nees belongs to the family Acanthaceae. It is an erect branched annual herb, 0.3-0.9m in height with quadrangular branches. Leaves are simple, lanceolate, acute at both ends, glabrous, with 4-6 pairs of main nerves. Flowers are small, pale but blotched and spotted with brown and purple distant in lax spreading axillary and terminal racemes or panicles. Calyx-lobes are glandular pubescent with anthers bearded at the base. Fruits are linear capsules and acute at both ends. Seeds are numerous, yellowish brown and sub-quadrate (Warrier et al,1993).Another species of Andrographis is A. echioides (Linn.) Nees. It is found in the warmer parts of India. The plant is a febrifuge and diuretic. It contains flavone-echiodinin and its glucoside-echioidin (Husain et al, 1992).Agrotechnology: The best season of planting Andrographis is May-June. The field is to be ploughed well, mixed with compost or dried cowdung and seedbeds of length 3m, breadth 1/2m and 15cm height are to be taken at a distance of 3m. The plant is seed propagated. Seeds are to be soaked in water for 6 hours before sowing. Sowing is to be done at a spacing of 20cm. Seeds may germinate within 15-20 days. Two weedings, first at one month after planting and the second at 2 month after planting are to be carried out. Irrigation during summer months is beneficial. The plant is not attacked by any serious pests or diseases. Flowering commences from third month onwards. At this stage, plant are to be collected, tied into small bundles and sun-dried for 4-5 days. Whole plant is the economic part and the yield is about 1.25t dried plants/ha (Prasad et al, 1997).Properties and activity: Leaves contain two bitter substances lactone “andrographolid” and “kalmeghin”. The ash contains sodium chloride and potassium salts. Plant is very rich in chlorophyte. Kalmeghin is the active principle that contains 0.6% alkaloid of the crude plant. The plant contains diterpenoids, andrographolide, 14-deoxy-11-oxo-andrographolide, 14-deoxy-11,12-dihydroandrographolide, 14-deoxy andrographolide and neoandrographolide (Allison et al, 1968). The roots give flavones-apigenin-7,4-dio-O-methyl ether, 5-hydroxy-7,8,2’,3’- tetramethoxyflavone, andrographin and panicolin and -sitosterol (Ali et al, 1972; Govindachari et al, 1969). Leaves contain homoandrographolide, andrographosterol and andrographone.The plant is vulnerary, antipyretic, antiperiodic, anti-inflammatory, expectorant, depurative, sudorific, anthelmintic, digestive, stomachic, tonic, febrifuge and cholagogue. The plant is antifungal, antityphoid, hepatoprotective, antidiabetic and cholinergic. Shoot is antibacterial and leaf is hypotensive(Garcia et al, 1980). This is used for the inflammation of the respiratory tract. In China, researchers have isolated the andrographolide from which soluble derivative such as 14-deoxy-11, 12-dehydro-andrographolide which forms the subject of current pharmacological and clinical studies. Apigenin 7,4’-O-dimethyl ether isolated from A. paniculata exhibits dose dependent, antiulcer activity in shay rat, histamine induced ulcer in guinea pigs and aspirin induced ulcers in rats. A crude substance isolated from methanolic extract of leaves has shown hypotensive activity.

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.
