sweet chestnut

Research has shown that sweet chestnut offers antioxidant properties. One French study in 2005 examined sweet chestnut leaf’s ability to inhibit free radicals and found that its antioxidant potential was at least on a par with that of quercetin and Vitamin E.

This may be explained by a number of compounds found in the leaves of the sweet chestnut – including rutin, quercetrin, apigenin, kaempferol and many others. Many of these antioxidant compounds are also found in the shell of the sweet chestnut.

But sweet chestnut’s antioxidant properties don’t end with the leaves and shells. One Spanish-Portugese study found that a decoction or infusion of the flowers also offered high flavonoids and antioxidant activity.

It’s important to note that most of these studies are referring to eating sweet chestnuts, not applying a topical skincare product containing sweet chest nut extract.
