• No reported folkloric medicinal use in the Philippines.
• In Brazilian folk medicine, used for rheumatism and inflammation.
• Larvicidal / Essential Oil:
A study of the essential oil for its larvicidal effect against four vector species of mosquitoes showed remarkable larvicidal properties, inducing 100% mortality in the larvae of Culex tritaeniorhynchus, A aegypti, A stephensi and Culex quinquefasciatus.
• Antinociceptive / Essential Oil:
Study yielded 3,5-di-O-caffeoylquinic acid and 4,5-di-O-caffeoylquinic acid which have been reported to have analgesic and antioxidative effects. The results show antinociceptive effects probably through release of pro-nociceptive mediators. The isolated caffeoylquinic acids can partly explain the antinociceptive effect of Ipomoea cairica polar extract.
