Indigofera tinctoria (lat. Indigofera tinctoria) - a shrub plant of the genus Indigofer (lat. Indigofera) of the glorious legume family (lat. Fabaceae). The leaves of the plant have long been used to produce a long-lasting blue dye that has been used to dye fabrics. The homeland of Indigofera dyeing is India, which has been famous for its bright fabrics throughout the centuries. From India, the plant has successfully "spread" to many countries with tropical climates so that local craftsmen can independently produce blue dye for dyeing fabrics. Although today man has learned to artificially synthesize blue paint, handicraft industries continue to use the old method of obtaining it. In addition, the plant has healing powers.

What's in your name

The generic Latin name "Indigofera" is a complex word consisting of two Latin words meaning "blue paint" and "bring, carry", which can be interpreted as "a plant that brings blue paint." This is due to the fact that there were times when Europeans used blue paint brought from India, where it was obtained from the leaves of such plants.

The Russian specific epithet "dyeing" is a literal translation of the Latin "tinctoria" and is also associated with the "artistic" abilities of the plant, which gives artists and fabric manufacturers a persistent blue dye.

Blue paint from India was discovered for Europeans by an Italian merchant named Marco Polo (1254 - 1324), who loved to travel the world.

Description

Depending on the climate where Indigofera dye has to grow, the plant can be annual, biennial or perennial. The place of residence of the shrub also affects its height, which ranges from one to two meters.

Light green leaves are feathery, similar to the leaves of Acacia. Each leaf consists of elliptical leaves arranged in pairs on the stem, in the amount of three to seven pairs. The surface of a simple leaf plate of miniature leaflets is bare, and the reverse side is covered with compressed hairs.

In the axils of the leaves, racemose inflorescences are born, formed by pink-purple flowers of the moth type, characteristic of plants of the legume family. The flowers unfurl their sails gradually, starting from the base of the inflorescence and gradually moving towards the top.

After pollination, the flower turns into a linear-cylindrical traditional pod, the outer surface of which is protected by white pubescence, and from four to six seeds are hidden inside.

Surprisingly, plants get a blue dye from green leaves. And such a magical transformation takes place due to the content in the leaves of a colorless substance called "indican glycoside". If you act on a glycoside, for example, with a weak acid, it breaks down to form glucose, loved by humans, and a colorless substance called aglycone indoxyl. The latter is so gentle that, once in the arms of the air, it immediately oxidizes and gives a person a "blue indigo". Such an artisan earthly nature!

Modern industry has learned to make an artificial blue dye, taking away the palm from Indigofera dyeing, but not completely displacing the plant from the suppliers of stable blue dye.

Soil Healer

Like most plants of the legume family, Indigofera dyeing house gives shelter to microorganisms on its roots, which saturate the soil with nitrogen. Therefore, the plant is planted in fields, the soil of which is depleted by previous plantings and needs to be treated.

Medicinal properties of the plant

Those who like to dye their hair black are familiar with a natural dye called "basma", which also heals the scalp. Its components are the leaves of Indigofera dyeing in company with the leaves of Thornless Lavsonia. From the dried leaves of the latter, a natural hair dye called "henna" is made. By adding the leaves of Indigofera dyeing plant to henna, they get "basma".

In the countries of Southeast Asia, Indigofera dye leaves are used to treat skin diseases, including fighting boils. Indian healers use the plant to treat liver problems.
