Neelini (Indigo Herb) Health Benefits [Amazing Plant]

Indigofera tinctoria (Neelini Herb or Indigo herb) is a plant species from the Fabaceae family that was and still is one of the sources for indigo dye. Neelini is a shrub that can grow one to two meters in height. It may be a perennial, a biennial, or an annual plant, depending on the climate where it grows. It is also cultivated as a ground cover that is soil-improving.

Neelini’s leaves are green when fresh and gray-black upon drying. The tender branches have a bluish-red tinge and the flowers are colored red or pink. The fruits are contained in cylindrical pods that are pale green-gray when young and become dark brown upon ripening.

Other names for neelini include: neela (Hindi); indigo or Indian indigo (English); neela chettu, aviri, nilimandu chettu (Telugu); Amari, avuri, or neelam (Tamil); and leela or lita (Malayalam).

Dye is obtained through processing the indigo plant’s leaves, which are immersed in water and are subsequently fermented to naturally convert the indican into indigotin (blue dye).

Aside from being a dye source, neelini is used to treat spleen and liver disorders, fever, gray hair, gout, rheumatoid arthritis, and other ailments.

The thirteenth century merchant traveler Marco Polo was the first to document indigo preparation in India. Thus, indigo was often used in paintings in Europe during the Middle Ages.

Hepato-protective activity for the Liver

Researchers from the Annamalai University in Tamil Nadu conducted an anti-hepatotoxic efficacy test of indigo powder extract on rats’ paracetamol-induced liver damage. Rise in serum levels of AST (aspartate amino transferase), ALT (alanine amino transferase), and other compounds were reported. Neelini extract’s anti-hepatotoxic efficacies were reported.

Nephro-protective activity for the Kidneys

The Govt. Siddha Medical College in Chennai conducted a kidney toxicity study. A water decoction of indigo leaves was given to rats with Cisplatin-induced renal damage. The water decoction decreased the toxicity caused by the Cisplatin. Changes were observed in urea and creatinine levels as well as in body weight.

The indigo-based trial drug protected kidneys from injury. Thus, indigo has considerable nephron-protective activity against renal damage induced by Cisplatin.
