Studies
Anti-tumor / Antibacterial: Study isolated an alkaloidal constituent, piperine which showed antitumor and antibacterial activity. Its inhibitory effect on crown-gall tumor suggests potential for exploitation of the plant species for cancer prevention and treatment. On antibacterial study, it showed good activity against Shigella dysenteriae, S aureus and B subtilis. (1)
Antidiarrheal:
Study of extract of Ludwigia hyssopifolia reduced gastrointestinal motility by 53.8% at 100 mg KBW with no inhibition at 50 mg KBW. (2)
Analgesic:
Study evaluated the analgesic activity of a methanolic extract of Jussiaea hyssopifolia plant in Swiss albino mice using a hot plate method. Results showed significant analgesic effect compared to standard drug diclofenac. (4)
Anhelmintic:
Study evaluated the methanolic extract of the entire plant of Jussiaea hyssopifolia for anthelmintic activity against earthworm Pheretima posthuma. Results showed significant anthelmintic effect in comparison to standard drug. (5)
