Uses of Curcumin:
The Curcumin is brightly colored and may be used as a food coloring. It has been used historically as a component of Indian Ayurvedic medicine since 1900 BCE to treat a wide variety of ailments.It is obtained from tumeric, the powdered root of curcuma longa. It is used in the preparation of curcuma paper and the detection of boron. Curcumin appears to possess a spectrum of pharmacological properties, due primarily to its inhibitory effects on metabolic enzymes.It is a natural phenolic compound. Potent anti-tumor agent having anti-inflammatory and anti-oxidant properties. Induces apoptosis in cancer cells and inhibits phorbol ester-induced protein kinase C (PKC) activity. Reported to inhibit production of inflammatory cytokines by peripheral blood monocytes and alveolar macrophages. Potent inhibitor of EGFR tyrosine kinase and IκB kinase. Inhibits inducible nitric oxide synthase (iNOS), cycloxygenase and lipoxygenase. Easily penetrates into the cytoplasm of cells, accumulating in membranous structures such as plasma membrane, endoplasmic reticulum and nuclear envelope.
