Ka taea te hanga i ngā rongoā ārai toto i roto i te rongoā, pērā i te double coumarin ethyl ester me te ketone benzyl coumarin.
Whakamahia hei takawaenga i roto i te umanga rongoā me te kakara.
Ko te waikawa Trans-4-hydroxycinnamic te e-isomer o te waikawa p-coumaric, he matū hydroxyl i ahu mai i te waikawa cinnamic, ā, he āhuatanga antioxidant tōna. Ko te waikawa coumaric tētahi wāhanga nui o te lignocellulose. Kua whakaatuhia e ngā rangahau ka taea e te waikawa p-coumaric te whakaiti i te mōrearea o te mate pukupuku mā te whakaiti i te hanganga o ngā nitrosamines e puta ai te mate pukupuku.
