English: Lac insect
Scientific Name: Kerria lacca (Kerr.)
The lac insect, also known as Kerria lacca, is a small insect native to Southeast Asia and India. It is a parasitic insect that feeds on the sap of host trees, particularly the "laksh" tree, which is where the name "lac" comes from.
The female lac insect produces a resinous secretion that hardens into a protective shell around her body. This shell, known as lac, is harvested and processed to produce various products, such as shellac, which is commonly used as a varnish, adhesive, and coating in a wide range of industries, including woodworking, food, and pharmaceuticals.
The harvesting of lac involves cutting the branches of the host trees, collecting the lac secretions, and processing them into various forms. This process has been practiced for centuries and is an important source of income for many rural communities in Southeast Asia and India.
In addition to its commercial uses, lac has also been used in traditional medicine for its purported health benefits. It is believed to have antioxidant, antimicrobial, and anti-inflammatory properties, and is used to treat a variety of conditions, such as fever, diarrhea, and skin disorders.
