Stenochlaena palustris (Vietnamese: choại, Tagalog: dilimán[1] or hagnaya[2]) is an edible medicinal fern species.
In the folk medicines of India and Malaysia, the leaves of this fern are used as remedies for fever, skin diseases, ulcers, and stomachache.
[5] Acylated flavonol glycosides isolated from the fern were found to have antibacterial activities.
[6] Crude and partially purified extracts prepared from the fern have been shown to exhibit antifungal,[7] antioxidant,[8] and antiglucosidase [9] activities.
In Vietnam, the young fronds are called đọt choại and can be used in soups, salads and some stir fry dishes, especially with garlic.
