Botany: Indigofera tinctoria Linn. syn. I. summatrana Gaertn, Pigmentum indicum belongs to Papilionaceae family. This is a branching shrub which grows upto 2m high. Stems and branches are green; branchlets silvery pubescent. Leaves are alternate, stipulate, imparipinnate and got 7-13 leaflets which are elliptic-oblong, membraneous,1.7x0.9cm, shortly mucronate, pale green or bluish. Flowers are small, rose-coloured in axillary racemes. Calyx 5-cleft, gamosepalous; corolla papilionaceous; stamens diadelphous; ovary sessile with a short incurved style ending in a capitate stigma. Pods are linear, cylindrical, 2-5cm long, deflexed having 8-12 seeds.

Agrotechnology: The Indian indigo requires good sunlight and grows well in hilly areas. This is usually propagated by seeds. Seeds are very small and the seed rate is 3kg/ha. Seeds require pretreatment for good germination as the seed coat is hard. Seeds are mixed with sand and ground gently to break the seed coat. An alternate method for enhancing germination is dipping the seeds in boiling water for a second. After pretreatment seeds are broadcasted. Broadcast the seeds preferably mixed with sand 2 or 3 times its volume to ensure uniform coverage. The seedbeds should be covered with straw and irrigated. Seeds germinate within 15 days. Seedlings are ready for transplanting after one month. For the land preparation, the soil is brought to fine tilth by ploughing 2 or 3 time s. Cattle manure should be applied at the rate of 10t/ha as basal dressing and incorporated into soil along with last ploughing. The best time for sowing is September-October. Weeding has to be done two times; 3 weeks after sowing and 6 weeks after sowing. Plants start flowering 2-3 months after sowing. Harvesting is done by cutting the plants at this time, at a height of about 10cm from ground level. Irrigate plants after harvest. Subsequent harvests can be made at 1.5-2 months interval. Four to five cuttings can be taken in an year depending on the growth. A few plants per plot are left without cutting to set seeds. Ripe pods are to be harvested in the early morning to prevent loss of seeds by shattering during harvest.

Properties and activity: A blue dyestuff is obtained from the indigofera which does not exist ready formed, but is produced during fermentation from another agent existing in the plant, known as indocan. Indocan is yellow amorphous of a nauseous bitter taste with an acid reaction, readily soluble in water, alcohol and ether. An artificial product indigotine is manufactured chemically and used as a substitute. Indirubin is another component of the plant.

The leaves, flowers and tender shoots are considered to be cooling, demulcent and alterative. Leaf is antiinflammatory. Root and stem is laxative, expectorant, antitumourous, febrifuge, anticephalalgic, antidote for snake bite, anthelmintic and promotes growth of hair. Root is divertic.
