Pteris ensiformis, the silver lace fern, sword brake fern or slender brake fern is a plant species in the genus Pteris found in tropical Africa, tropical Asia and the Pacific.

It is the most common ingredient of traditional herbal drinks in Taiwan containing different phenolic compounds : kaempferol 3-O-α-l-rhamnopyranoside-7-O-[α-d-apiofuranosyl-(1-2)-β-d-glucopyranoside], 7-O-caffeoylhydroxymaltol 3-O-β-d-glucopyranoside, hispidin 4-O-β-d-glucopyranoside, kaempferol 3-O-α-l-rhamnopyranoside-7-O-β-d-glucopyranoside, caffeic acid, 5-O-caffeoylquinic acid, 3,5-di-O-caffeoylquinic acid and 4,5-di-O-caffeoylquinic acid.^[1]

This plant is resistant to arsenic-induced oxidative stress.^[2]

Benzoyl-beta-D-glucoside, as well as pterosin sesquiterpenes can be found in P. ensiformis.^[3]
