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,[1] and in honeycomb.
Aromatase inhibition[edit]
Studies performed in vivo show that orally administered chrysin does not have clinical activity as an aromatase inhibitor.[2][3]
Chrysin is available as a bodybuilding supplement and it is taken with the hope of raising testosterone levels or stimulating testosterone production; however, there is no clinical evidence for this effect.
Inflammation[edit]
Chrysin is under laboratory research for its potential effects on inflammation,[4] but there is no evidence it has anti-inflammatory activity in humans.
Bioavailability[edit]
Following oral intake by humans, chrysin has low bioavailability and rapid excretion.[5]
