REVIEW Chrysin is a naturally occurring flavone chemically extracted from the passion flowers Passiflora caerulea and Passiflora incarnata. Honeycomb also contains small amounts. It is also reported in the mushroom Pleurotus ostreatus, chamomile, and Oroxylum indicum or Indian trumpetflower. Chrysin has been shown to induce an anti-inflammatory effect, most likely by inhibition of COX-2 expression and via IL-6 signaling.
