Description: Chrysin is a naturally occurring flavone, a type of flavonoid. It is found in the passion flowers Passiflora caerulea and Passiflora incarnata, and in Oroxylum indicum. It is also found in chamomile, in the mushroom Pleurotus ostreatus, and in honeycomb. At high concentrations, chrysin is reported to be an aromatase inhibitor in vitro. However, studies performed in vivo show that orally administered chrysin does not have clinical activity as an aromatase inhibitor.
