Uses

Beverages

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]
