Several recent studies with this flavonoid suggest that it may have a potent anti-cancer effect, specifically through inhibition of the detoxification enzyme CYP1A1 and modulation of the aryl hydrocarbon receptor. |
Galangin has also been shown to be a potent preserver of the endogenous free radical scavenger glutathione, thereby playing another anti-carcinogenic role. |
Galangin also exerts a strong inhibitory effect on the cyclo-oxygenase family of enzymes; this provides a strong cardioprotective effect by inhibiting the aggregation of platelets, as well as providing a consistent systemic anti-inflammatory effect. |
