Rich in red wine, peanuts, and grape skin, resveratrol is a polyphenol
that has been demonstrated to possess anti-inflammatory, anti-cancer,and antioxidant properties. It may help mitigate allergic inflammation.
We looked at how resveratrol and the anti-allergy medication tranilast affected human mast cell activation. Resveratrol and tranilast both prevented substance P, IgE/anti-IgE, and compound 48/80 from inducing
degranulation in LAD2 mast cells. When added concurrently to physiological stimuli, resveratrol inhibited degranulation immediately and
maintained the effect for up to 24 hours. Although cAMP was not necessary for the inhibitory effect, it might have been caused by calcium
modulation, resveratrol, and, to a lesser extent, tranilast, which preceded substance P-induced elevations.
