Uses edit

Beverages edit

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.[4]

This plant is resistant to arsenic-induced oxidative stress.[5]

Benzoyl-beta-D-glucoside, as well as pterosin sesquiterpenes can be found in P. ensiformis.[6]

Cultivation edit

Pteris ensiformis is cultivated as an ornamental plant for tropical and subtropical climate gardens, and as a house plant.

  • Pteris ensiformis 'Victoriae', the Victoria fern
  • Pteris ensiformis 'Evergemiensis'
