Importance: Garlic is one of the important bulb crops used as a spice or condiment with medicinal value throughout the world. It possesses high nutritive value. Its preparations are useful in vitiated conditions of kapha and vata, cough, whooping cough, bronchitis, asthma, fever, facial paralysis, flatulence, colic, constipation, atonic dyspepsia, helminthiasis, duodenal ulcers, pulmonary and laryngeal tuberculosis, opthalmopathy, cardiopathy, fatigue, leucoderma, leprosy, hysteria, haemorrhoids, sciatica, otalgia, lumbago, swellings, splenopathy, hepatopathy, pneumonopathy, anthralgia, sore eyes, ear ache and dental caries (Kumar et al, 1997).

Distribution: Garlic is a native of Southern Europe and it is cultivated all over the world.. It is grown throughout India; Gujarat and Orissa being the leading states.

Botany: The genus Allium of Liliaceae family comprises a number of species. The important ones are the following:

A. sativum Linn. syn. A. porrum Linn.

A. cepa Linn.

A. ampeloprasum Linn.

A. ascalonicum Linn. A. leptophyllum Wall. A. macleanii Baker.

A. schoenoprasum Linn.

A. tuberosum Roxb.

Allium sativum is a scapigerous foetid perennial medicinal herb with underground compound bulbs covered over by outer white thin scales and with simple smooth, round stem, surrounded at the bottom by tubular leaf sheath. The leaves are simple, long, flat and linear. The flowers are small and white arranged in rounded umbels mixed with small bulbils. The entire umbel is enclosed in a tear-drop-shaped membranous spathe. Flowers are usually sterile (Warrier et al, 1993).

Agrotechnology: Garlic can be grown under a wide range of climatic conditions. It prefers moderate temperature in summer as well as in winter. Short days are very favourable for the formation of bulbs. Garlic requires well drained loamy soils rich in humus, with fairly good content of potash. Garlic is propagated by cloves or bulblets. In the hills, sowing is done in April and May. Types with bold and compact cloves and thick white covering sheath are preferred for planting. Ootty-1 garlic is an improved variety by clonal selection released from TNAU, Coimbatore. Garlic may be broadcast, planted in furrows or dibbled at the rate of 150-200kg cloves/ha. In furrow planting, cloves are dropped 7.5-10cm apart in furrows 15cm deep and covered lightly with loose soil. Cloves may be dibbled 5 to 7.5cm deep and 7.5cm apart in rows which are 15cm apart with their growing end upwards and then covered with loose soil. A basal dose of 60kg N and 50kg each of P2O5 and K2O are applied along with 25t/ha of FYM. 60kg N is given as topdressing 45 days after planting. First irrigation is given immediately after sowing and subsequent irrigations are given at 10-15 days interval depending upon the soil moisture availability. The last irrigation should be given 2-3 days before harvesting to facilitate easy harvest and minimum damage to bulbs. First weeding and hoeing is to be done at one mo nth after sowing followed by a second weeding one month after first interculture. Hoeing at about two and a half months from sowing loosens the soil and helps in setting of bigger and well-filled bulbs. Garlic is attacked by Thrips tabacii which causes withering of leaves. Application of methyl demeton 25EC or dimethoate 30EC at 1ml/l will check the pest incidence. Leaf spot caused by Alternaria solanii can be controlled by spraying Dithane M.45 at fortnightly intervals at 2.5g/l of water. Garlic is harvested when the tops turn yellowish or brownish and show signs of drying up. The plants are uprooted, tied into small bundles and kept in shade for 2-3 days for curing. Average yield of garlic is 6-8t/ha. (Kumar et al, 1997.)

Properties and activity: Garlic bulb is reported to contain volatile oil, alliin (S-allyl-L-cysteine sulfoxide), S-methyl-L-cysteine sulfoxide and allinase. It is rich in vitamins like thiamine, riboflavine and niacin. Volatile oil contains allicin (diallyl thiosulphinate), an active odour principle of garlic. Other major compounds present are diallyl disulphide, diallyl trisulphide, allyl methyl trisulphide and allyl methyl disulphide (Husain et al., 1992).

Garlic bulb is antirheumatic, stimulant, diaphoretic, expectorant, diuretic, antispasmodic, astringent, antiparalytic, antileprotic, aperient, febrifuge, carminative, stomachic, alterative and emmenagogue. The essential oil is hypocholestrolemic, hypotensive, antitumour and antidiabetic. Diallyl disulphide and diallyl trisulphide from essential oil have larvicidal action. Bulbs also have anti-bacterial, and anti-fungal activity.... garlic

Tam: Atutinnappalai

Importance: The bracteated birthwort or worm killer is a perennial prostrate herb. As the name suggests it is a killer of intestinal worms especially roundworms. It is also used in vitiated conditions of kapha and vata, constipation, inflammations, amenorrhoea, dysmenorrhoea, foul ulcers, boils, syphilis, gonorrhoea, dyspepsia, colic, skin diseases, eczema, artheralgia and intermittent fevers. The plant is an insect repellent due to the presence of aristolochic acid, which is poisonous to man and livestock. Plant is also used against scorpion sting. Seeds ground in water to form a lotion and used for softening hair. Powdered root is used in fertility control.

Distribution: The plant is found in Sri Lanka, Arabian countries and tropical Africa. In India, the plant is grown in Deccan and Carnatic Plateau.

Botany: Aristolochia bracteolata Lam. syn. A. bracteata Retz. belongs to the family Aristolochiaceae. It is a perennial prostrate herb with weak, glabrous stems. Leaves are simple, alternate, reniform or broadly ovate, cordate at the base with a wide sinus upto 7.5cm in diameter, reticulately veined. Flowers are solitary with a large sessile orbicular bract at the base. Perianth tube is cylindric with dark purple tip having revolute margins. Fruits are oblong-ellipsoid 12-ribbed glabrous capsules. Seeds are deltoid with slightly cordate base (Warrier et al, 1993) Another important species belonging to the genus Aristolochia is A. indica Linn. The plant grows wild throughout the low hills and plains of India from Nepal to West Bengal and South India. It is a valuable anti-dote to snake bite and to bites of poisonous insects as scorpion, etc. It is given in cases of cholera and diarrhoea after macerating with black pepper corns. The juice of the leaves has stimulant, tonic and antiperiodic properties.

Agrotechnology: Shady areas and well-drained soils are most suited to Aristolochia. The plant can be seed propagated. 3-month-old seedlings raised in polybags are required for transplanting. Pits of size 50cm cube are to be taken at a distance of 3m and filled with sand, topsoil and dried cowdung. To these pits, the seedlings are to be transplanted. Regular irrigation and organic manure application is beneficial. The plant is to be trailed on iron wires tied to poles. The plant is not attacked by any serious pests or diseases. Plant attains good spread within one year. Leaves can be collected for the next 10 years. Roots and leaves constitute the economi c parts (Prasad et al, 1997).

Properties and activity: Leaves and fruits yield ceryl alcohol, -sitosterol and aristolochic acid. Root contains aristolochic acid. Seeds give an alkaloid magnoflorine, aristolochic acid, fatty oil comprising palmitic, stearic, lignoseric and oleic acids and -sitosterol.

The plant is anthelmintic, cathartic, antiperiodic and emmenagogue. Leaf is antigonorrhoeic, larvicidal and used in eczema on children’s leg and ulcers. The plant is oxytocic (Husain et al,1992).... worm killer

Ammi majus

Apiaceae

Importance: Greater Ammi, also known as Bishop’s weed or Honey plant is an annual or biennial herb which is extensively used in the treatment of leucoderma (vitiligo) and psoriasis. The compounds responsible for this are reported to be furocoumarins like ammoidin (xanthotoxin), ammidin (imperatorin) and majudin (bergapten) present in the seed. Xanthotoxin is marketed under the trade name “Ox soralen” which is administered orally in doses of 50 mg t.d. or applied externally as 1% liniment followed by exposure of affected areas to sunlight or UV light for 2 hours. It is also used in “Suntan lotion”. Meladinine is a by-product of Ammi majus processing, containing both xanthotoxin and imperatorin sold in various formulations increases pigmentation of normal skin and induces repigmentation in vitiligo. Imperatorin has antitumour activity. Fruit or seed causes photosensitization in fouls and sheep.

Distribution: The plant is indigenous to Egypt and it grows in the Nile Valley, especially in Behira and Fayoom. It is also found in the basin of the Mediterranean Sea, in Syria, Palestine, Abyssinia, West Africa, in some regions of Iran and the mountains of Kohaz (Ramadan, 1982). It grows wild in the wild state in Abbottabad, Mainwali, Mahran and is cultivated in Pakistan. The crop was introduced to India in the Forest Research Institute, Dehra Dun, in 1955 through the courtesy of UNESCO. Since then, the crop has been grown for its medicinal fruit in several places in Uttar Pradesh, Gujarat, Kashmir and Tamil Nadu.

Botany: Ammi majus Linn. belongs to the family Apiaceae (Umbelliferae). A. visnaga is another related species of medicinal importance. A. majus is an annual or beinnial herb growing to a height of 80 to 120 cm. It has a long tap root, solid erect stem, decompound leaves, light green alternate, variously pinnately divided, having lanceolate to oval segments. Inflorescence is axillary and terminal compound umbels with white flowers. The fruits are ribbed, ellipsoid, green to greenish brown when immature, turning reddish brown at maturity and having a characteristic terebinthinate odour becoming strong on crushing with extremely pungent and slightly bitter taste.

Agrotechnology: Ammi is relatively cold loving and it comes up well under subtropical and temperate conditions. It does not prefer heavy rainfall. Though the plant is biennial it behaves as an annual under cultivation in India. A mild cool climate in the early stages of crop growth and a warm dry weather at maturity is ideal. It is cultivated as a winter annual crop in rabi season. A wide variety of soils from sandy loam to clay loam are suitable. However, a well drained loamy soil is the best. Waterlogged soils are not good. Being a hardy crop, it thrives on poor and degraded soils.

The plant is seed propagated. Seeds germinate within 10-12 days of sowing. The best time of sowing is October and the crop duration is 160-170 days in north India. Crop sown later gives lower yield. The crop can be raised either by direct sowing of seed or by raising a nursery and then transplanting the crop. Seed rate is 2 kg/ha. The land is brought to a fine tilth by repeated ploughing and harrowing. Ridges and furrows are then formed at 45-60 cm spacing. Well decomposed FYM at 10-15 t/ha and basal fertilisers are incorporated in the furrows. Seeds being very small are mixed with fine sand or soil, sown in furrows and covered lightly with a thin layer of soil. A fertilizer dose of 80:30:30 kg N, P2O5 and K2O/ha is generally recommended for the crop while 150:40:40 kg/ha is suggested in poor soils for better yields. The furocoumarin content of Ammi majus is increased by N fertiliser and the N use efficiency increases with split application of N at sowing, branching and at flowering. For obtaining high yields it is essential to give one or two hoeings during November to February which keeps down the weeds. If winter rains fail, one irrigation is essential during November to January. As the harvesting season is spread over a long period of time, two irrigations during March and April meets the requirements of the crop (Chadha and Gupta, 1995).

White ants and cut worms are reported to attack the crop which can be controlled by spraying the crop with 40g carbaryl in 10 l of water. Damping off and powdery mildew are the common diseases of the crop. Seed treatment with organomercuric compounds is recommended for damping off. To control powdery mildew the crop is to be sprayed with 30g wettable sulphur in 10 l of water whenever noticed.

The crop flowers in February. Flowering and maturity of seed is spread over a long period of two months. The primary umbels and the early maturing secondary umbels are the major contributors to yield. A little delay in harvesting results in the shattering of the seed which is the main constraint in the commercial cultivation of the crop and the main reason for low yields in India. Sobti et al (1978) have reported increased yield by 50 - 60% by the application of planofix at 5 ppm at flower initiation and fruit formation stages. The optimum time of harvest is the mature green stage of the fruit in view of the reduced losses due to shattering and maximum contents of furocoumarins. The primary umbels mature first within 35-45 days. These are harvested at an interval of 2-4 days. Later, the early appearing secondary umbels are harvested. Afterwards, the entire crop is harvested, stored for a couple of days and then threshed to separate the seeds. The seed yield is 900-1200 kg/ha.

Postharvest technology: The processing of seed involves solvent extraction of powdered seeds, followed by chilling and liquid extraction and chromatographic separation after treatment with alcoholic HCl. Bergapten, xanthotoxin and xanthotoxol can be separated. Xanthotoxol can be methylated and the total xanthotoxin can be purified by charcoal treatment in acetone or alcohol.

Properties and activity: Ammi majus fruit contains amorphous glucoside 1%, tannin 0.45%, oleoresin 4.76%, acrid oil 3.2%, fixed oil 12.92%, proteins 13.83% and cellulose 22.4%. This is one of the richest sources of linear furocoumarins. Ivie (1978) evaluated the furocoumarin chemistry of taxa Ammi majus and reported the presence of xanthotoxin, bergapten, imperatorin, oxypencedanin, heraclenin, sexalin, pabulenol and many other compounds. Furocoumarins have bactericidal, fungicidal, insecticidal, larvicidal, moluscicidal, nematicidal, ovicidal, viricidal and herbicidal activities (Duke, 1988).... greater ammi

DISTRIBUTION: Native to the Moluccas and nearby islands; cultivated in Indonesia, Sri Lanka and the West Indies, especially Grenada.

EXTRACTION: Essential oil by steam (or water) distillation from 1. the dried worm eaten nutmeg seed (the worms eat away all the starch and fat content); 2. the dried orangebrown aril or husk – mace; and 3. an oleoresin is also produced in small quantities by solvent extraction from mace. The oil is also distilled in the USA and Europe from the imported nutmegs.

OTHER SPECIES: Indonesia and Sri Lanka produce the so-called ‘East Indian’ nutmeg which is considered superior, while Grenada produces the ‘West Indian’ nutmeg – see also Botanical Classification.

HERBAL/FOLK TRADITION: Nutmeg and mace are widely used as domestic spices in the East and West. They have been used for centuries as a remedy mainly for digestive and kidney problems. In Malaysia they are used during pregnancy to strengthen and tone the uterine muscles. Grated nutmeg with lard is used for piles. A fixed oil of nutmeg is also used in soap and candle making.

Nutmeg is current in the British Herbal Pharmacopoeia indicated for flatulent dyspepsia, nausea, diarrhoea, dysentery, and topically for rheumatism.

ACTIONS: Analgesic, anti-emetic, antioxidant, antirheumatic, antiseptic, antispasmodic, aphrodisiac, carminative, digestive, emmenagogue, gastric secretory stimulant, larvicidal, orexigenic, prostaglandin inhibitor, stimulant, tonic.

CHARACTERISTICS: 1. A water-white or pale yellow mobile liquid with a sweet, warm-spicy odour and a terpeney top-note. 2. A water white or pale yellow mobile liquid with a sweet, warm-spicy scent. 3. An orange-brown viscous liquid with a fresh, spicy-warm, balsamic fragrance. It has good masking power.

They blend well with oakmoss, lavandin, bay leaf, Peru balsam, orange, geranium, clary sage, rosemary, lime, petitgrain, mandarin, coriander and other spice oils.

PRINCIPAL CONSTITUENTS: Mainly monoterpene hydrocarbons (88 per cent approx.): camphene, pinene, dipentene, sabinene, cymene, with lesser amounts of geraniol, borneol, linalol, terpineol, myristicin (4–8 per cent), safrol and elemincin, among others. Mace oil contains similar constituents but contains more myristicin.

SAFETY DATA: Both nutmeg and mace are generally non-toxic, non-irritant and non sensitizing. However, used in large doses they show signs of toxicity such as nausea, stupor and tachycardia, believed to be due to the myristicin content. ‘Large quantities are hallucinogenic and excitant to the motor cortex.’. On this basis nutmeg (especially the West Indian type) is probably safer to use than mace. Use in moderation, and with care in pregnancy.
