It acts well on the liver, promoting secretion of bile. Used in jaundice and torpid liver, flatulence and diarrhoea of children, colic, strangulation of intestines and splenomegaly; also for cold and upper respiratory tract infections.
Key application: As bitter tonic, febrifuge and hepatoprotective. (Indian Herbal Pharmacopoeia.)Kaalmegha, officinal in IP, consists of dried leaves and tender shoots, which yield not less than 1% andro- grapholide on dry-weight basis.Several active constituents have been identified from the leaf and rhizome, including andrographolide, deoxyan- drographolide and other diterpenes.Andrographolide exhibited strong choleretic action when administered i.p. to rats. It induces increase in bile flow together with change in physical properties of bile secretion. It was found to be more potent than sily- marin.Andrographolide was found to be almost devoid of antihepatitis-B virus surface antigen-like activity (when compared with picroliv.)The leaf and stem extracts of Kaal- megha/andrographolide given s.c. or orally did not change blood sugar level of normal or diabetic rats.Alcoholic extract of the plant exhibited antidiarrhoeal activity against E. coli enterotoxins in animal models.Clinical evidence of effectiveness of andrographis in humans is limited to the common cold. Preliminary evidence suggests that it might increase antibody activity and phagocytosis by macrophages, and might have mast cell-stabilizing and antiallergy activity. (Natural Medicines Comprehensive Database, 2007.)The herb is contraindicated inbleed- ing disorders, hypotension, as well as male and female sterility (exhibited infertility in laboratory animals).Dosage: Whole plant—5-10 ml juice; 50-100 ml decotion; 1-3 g powder.

Mal: Kadamba, KollankovaTam: Akashagarudan, Gollankovai;Tel: Murudonda, NagadondaCorallocarpus is a prostrate or climbing herb distributed in Punjab, Sind, Gujarat, Deccan, Karnataka and Sri Lanka. It is monoecious with large root which is turnip-shaped and slender stem which is grooved, zigzag and glabrous. Tendrils are simple, slender and glabrous. Leaves are sub-orbicular in outline, light green above and pale beneath, deeply cordate at the base, angled or more or less deeply 3-5 lobed. Petiole is long and glabrous. Male flowers are small and arranged at the tip of a straight stiff glabrous peduncle. Calyx is slightly hairy, long and rounded at the base. Corolla is long and greenish yellow. Female flowers are usually solitary with short, stout and glabrous peduncles. Fruit is stalked, long, ellipsoid or ovoid. Seeds are pyriform, turgid, brown and with a whitish corded margin. It is prescribed in later stages of dysentery and old veneral complaints. For external use in chronic rheumatism, it is made into a liniment with cumin seed, onion and castor oil. It is used in case of snakebite where it is administered internally and applied to the bitten part. The root is given in syphilitic rheumatism and later stages of dysentery. The plant is bitter, sweet, alexipharmic and emetic. The root is said to possess alterative and laxative properties (Kirtikar and Basu, 1988). Root contains a bitter principle like Breyonin (Chopra et al, 1980).Agrotechnology: Cucurbits can be successfully grown during January-March and September- December. For the rainfed crop, sowing can also be started after the receipt of the first few showers.Pits of 60cm diameter and 30-45cm depth are to be taken at the desired spacing. Well rotten FYM or vegetable mixture is to be mixed with topsoil in the pit and seeds are to be sown at 4-5/pit. Unhealthy plants are to be removed after 2 weeks and retained 2-3 plants/pit. FYM is to be applied at 20-25t/ha as basal dose along with half dose of N (35kg/ha) and full dose of P (25kg) and K (25kg). The remaining dose of N (35kg) can be applied in 2 equal split doses at fortnightly intervals. During the initial stages of growth, irrigation is to be given at an interval of 3-4 days and at alternate days during flowering and fruiting periods. For trailing cucumber, pumpkin and melon, dried twigs are to be spread on the ground. Bitter gourd, bottle gourd, snake gourd and ash gourd are to be trailed on Pandals. Weeding and raking of the soil are to be conducted at the time of fertilizer application. Earthing up may be done during rainy season. The most dreaded pest of cucurbits is fruit flies which can be controlled by using fruit traps, covering the fruits with polythene, cloth or paper bags, removal and destruction of affected fruits and lastly spraying with Carbaryl or Malathion 0. 2% suspension containing sugar or jaggery at 10g/l at fortnightly intervals after fruit set initiation. During rainy season, downy mildew and mosaic diseases are severe in cucurbits. The former can be checked by spraying Mancozeb 0.2%. The spread of mosaic can be checked by controlling the vectors using Dimethoate or Phosphamidon 0.05% and destruction of affected plants and collateral hosts. Harvesting to be done at least 10 days after insecticide or fungicide application (KAU,1996).... cucurbitsHabitat: Throughout the greater part of India.

It is widely distributed in Khasi, Jaintia and Naga hills of Assam and Manipur upto 2000m and in Sikkim, West Bengal, Orissa and in the Niligiris. The plant and berries contain solasonine (which on hydrolysis yields solasodine), solamargine, khasianine, nantigenin, solasodine, diosgenin and saponin-solakhasianin. The plant is spasmolytic and CNS active. The berry is a source of solasodine used in the synthesis of corticosteroidal hormones.Agrotechnology: The agrotechnology for the solanaceous group of plants are almost similar. They come up very well in tropical and subtropical climate upto 2000m altitude. They can be raised on a variety of soils good in organic matter. Propagation is by seeds. The seedlings are first raised in the nursery and transplanted to the main field 30-45 days after sowing when the plants attain 8-10cm height. During rainy season, planting is done on ridges while during summer in furrows, at a spacing ranging from 30-90cm depending upon the stature and spreading habit of the plant. The transplanted seedlings should be given temporary shade for 2-4 days during summer. FYM or compost at 20-25t/ha is applied at the time of land preparation. A moderate fertiliser dose of 75:40:40 N, P2O5, K2O/ha may be given. P is given as basal dose, N and K are applied in 2-3 split doses. One or two intercultural operations are needed to control weeds. The plants need earthing up after weeding and topdressing. Irrigation is needed at 3-4 days interval during summer and on alternate days during fruiting period. Plants need staking to avoid lodging due to heavy bearing. Shoot borers, mealy bugs, leaf webbers and miners are noted on the crop, which can be controlled by spraying mild insecticides. Root knot nematode, wilting and mosaic diseases are also noted on the crop. Field sanitation, crop rotation and burning of crop residues are recommended.... solanumsHabitat: Arid regions, on saline lands and in coastal regions.

(CCRAS.)... salvadora persicaDuring a bite by the female mosquito, one or more sporozoites – a stage in the life-cycle of the parasite – are injected into the human circulation; these are taken up by the hepatocytes (liver cells). Following division, merozoites (minute particles resulting from the division) are liberated into the bloodstream where they invade red blood cells. These in turn divide, releasing further merozoites. As merozoites are periodically liberated into the bloodstream, they cause the characteristic fevers, rigors, etc.
Malaria occurs in many tropical and subtropical countries; P. falciparum is, however, con?ned very largely to Africa, Asia and South America. Malaria is present in increasingly large areas; in addition, the parasites are developing resistance to various preventative and treatment drugs. The disease constitutes a signi?cant problem for travellers, who must obtain sound advice on chemoprophylaxis before embarking on tropical trips – especially to a rural area where intense transmission can occur. Transmission has also been recorded at airports, and following blood transfusion.
The World Health Organisation (WHO) has listed malaria as one of Europe’s top ten infectious diseases. In 1992, 20,000 cases were reported: this had risen to more than 200,000 by the late 1990s. The resurgence of malaria has been worldwide, in part the result of the development of resistant strains of the disease, and in part because many countries have failed (or been unable) to implement environmental measures to eliminate mosquitoes. Nearly 40 years ago the WHO forecast that by 1980 only four million people would be affected worldwide; now, at the beginning of the 21st century, around 500 million people a year are contracting malaria with about 3,000 people a day dying from the infection – as many as 70 per cent of them children under the age of ?ve, according to WHO ?gures. The apparently steady advance of global warming means that countries with temperate climates may well warm up su?ciently to enable malaria to become established as an ENDEMIC disease. In any case, the great increase in international air travel has exposed many more people to the risk of malaria, and infected individuals may not exhibit symptoms until they are back home. Doctors seeing a recent traveller with unexplained pyrexia and illness should consider the possibility of malarial infection.
Diagnosis is by demonstration of trophozoites – a stage in the parasite’s life-cycle that takes place in red blood cells – in thick/thin blood-?lms of peripheral blood. Serological tests are of value in deciding whether an individual has had a past infection, but are of no value in acute disease.
P. vivax and P. ovale infections cause less severe disease than P. falciparum (see below), although overall there are many clinical similarities; acute complications are unusual, but chronic ANAEMIA is often present. Primaquine is necessary to eliminate the exoerythrocytic cycle in the hepatocyte (liver cell).
P. falciparum Complications of P. falciparum infection include cerebral involvement (see BRAIN – Cerebrum), due to adhesion of immature trophozoites on to the cerebral vascular endothelium; these lead to a high death rate when inadequately treated. Renal involvement (frequently resulting from HAEMOGLOBINURIA), PULMONARY OEDEMA, HYPOTENSION, HYPOGLYCAEMIA, and complications in pregnancy are also important. In complicated disease, HAEMODIALYSIS and exchange TRANSFUSION have been used. No adequate controlled trial using the latter regimen has been carried out, however, and possible bene?ts must be weighed against numerous potential side-effects – for instance, the introduction of a wide range of infections, overload of the circulatory system with infused ?uids, and other complications.
P. malariae usually produces a chronic infection, and chronic renal disease (nephrotic syndrome) is an occasional sequel, especially in tropical Africa.
Gross SPLENOMEGALY (hyper-reactive malarious splenomegaly, or tropical splenomegaly syndrome) can complicate all four human Plasmodium spp. infections. The syndrome responds to long-term malarial chemoprophylaxis. BURKITT’S LYMPHOMA is found in geographical areas where malaria infection is endemic; the EPSTEIN BARR VIRUS is aetiologically involved.
Prophylaxis Malaria specialists in the United Kingdom have produced guidance for residents travelling to endemic areas for short stays. Drug choice takes account of:
risk of exposure to malaria;
extent of drug resistance;
e?cacy of recommended drugs and their side-effects;
criteria relevant to the individual (e.g. age, pregnancy, kidney or liver impairment). Personal protection against being bitten by
mosquitoes is essential. Permethrinimpregnated nets are an e?ective barrier, while skin barrier protection and vaporised insecticides are helpful. Lotions, sprays or roll-on applicators all containing diethyltoluamide (DEET) are safe and work when put on the skin. Their e?ect, however, lasts only for a few hours. Long sleeves and trousers should be worn after dark.
Drug prophylaxis should be started at least a week before travelling into countries where malaria is endemic (two or three weeks in the case of me?oquine). Drug treatment should be continued for at least four weeks after leaving endemic areas. Even if all recommended antimalarial programmes are followed, it is possible that malaria may occur any time up to three months afterwards. Medical advice should be sought if any illness develops. Chloroquine can be used as a prophylactic drug where the risk of resistant falciparum malaria is low; otherwise, me?oquine or proguanil hydrochloride should be used. Travellers to malaria-infested areas should seek expert advice on appropriate prophylactic treatment well before departing.
Treatment Various chemoprophylactic regimes are widely used. Those commmonly prescribed include: chloroquine + paludrine, me?oquine, and Maloprim (trimethoprim + dapsone); Fansidar (trimethoprim + sulphamethoxazole) has been shown to have signi?cant side-effects, especially when used in conjunction with chloroquine, and is now rarely used. No chemotherapeutic regimen is totally e?ective, so other preventive measures are again being used. These include people avoiding mosquito bites, covering exposed areas of the body between dusk and dawn, and using mosquito repellents.
Chemotherapy was for many years dominated by the synthetic agent chloroquine. However, with the widespread emergence of chloroquine-resistance, quinine is again being widely used. It is given intravenously in severe infections; the oral route is used subsequently and in minor cases. Other agents currently in use include me?oquine, halofantrine, doxycycline, and the artemesinin alkaloids (‘qinghaosu’).
Researchers are working on vaccines against malaria.... malaria
