What is Luteolin?
Luteolin is a flavone, a type of flavonoid, with a yellow crystalline appearance.[1] Luteolin can function as either an or a pro-oxidant and plants rich in luteolin have been used in Chinese traditional medicine.
Luteolin is the principal yellow dye compound that is obtained from the plant Reseda luteola, which has been used as a source of the dye since at least the first millennium B.C. Luteolin was first isolated in pure form, and named, in 1829 by the French chemist Michel Eugène Chevreul. The luteolin empirical formula was determined by the Austrian chemists Heinrich Hlasiwetz and Leopold Pfaundler in 1864.[6][7] In 1896, the English chemist Arthur George Perkin proposed the correct structure for luteolin.[8] Perkin's proposed structure for luteolin was confirmed in 1900 when the Polish-Swiss chemist Stanislaw Kostanecki (1860–1910) and his students A. Różycki and J. Tambor synthesized luteolin.

Luteolin benefits
1. Luteolin is a potent inhibitor of various hyaluronidases, which are enzymes that change hyaluronic acid. One of the polymers that is responsible for the toughness and flexibility of cartilage and tendon is hyaluronic acid, which is a heteropolysaccharide.
2. Luteolin has spasmodic properties: In the guinea pig model of modified air overflow, luteolin demonstrated potent anti-histamine properties and significantly inhibited acetylcholine- and histamine-induced smooth muscle contraction.
3. Luteolin has antileishmanial properties.
4. In mice, luteolin has a strong antinociceptive effect against pain from peripheral nerves. This is in line with the fact that Luteolin is a component of the Brazilian plant Wedelia paludosa, which has been used for centuries to treat a wide range of conditions, including painful ones.
