- Introduction:
Chrysin is one of the most well known estrogen blockers.
Chrysin is a dihydroxyflavone in which the two hydroxy groups are located at positions 5 and 7. It has a role as an anti-inflammatory agent, an antineoplastic agent, an antioxidant, a hepatoprotective agent, an EC 2.7.11.18 (myosin-light-chain kinase) inhibitor and a plant metabolite. It is a dihydroxyflavone and a 7-hydroxyflavonol.

- 9.2 Description
- Chrysin is a natural flavonoid with antioxidant, anti-inflammatory, and anticancer properties. It blocks COX-2 gene expression, PGE2 production, and hydroxyl radical formation in LPS-induced RAW 264.7 cells.1,2 Chrysin inhibits insulin-induced HIF-1α expression (~50% at 10 μM) in human prostate cancer DU145 cells and blocks DU145 xenograft-induced angiogenesis in vivo.3 In a mouse model of ischemia/reperfusion injury, chrysin decreased pro-inflammatory gene expression and oxidative stress, resulting in a reduction of infarct volume and neurological defects.4

- beige powder
- 9.4 Uses
- diuretic
- 9.5 Uses
- Chrysin is a flavanoid with anti-inflammatory effect and potential protective effects against cancer and cardiovascular disease. Studies show that Chrysin is central benzodiazepine receptor ligand wit h possible anxiolytic effects. Chrysin was initially believed to have aromatase inhibitor but recent in vivo studies have disproved that.
