Studies
• Antibacterial:
Antibacterial
Activities And Toxicological Potentials Of Crude Ethanolic Extracts
Of Euphorbia hirta: The study showed the ethanolic
extract to inhibit the growth of test isolates except Salmonella typhi.
The antibacterial effect was attributed to the presence of alkaloids,
tannins and flavonoids which have been shown to have antibacterial properties.
The results support its use in traditional medicine.
• Diuretic: Euphorbia
hirta leaf extracts increase urine output and electrolytes in rats:
Studty suggests that the active components in the water extract of E.
hirta leaf had similar diuretic effect as that of acetazolamide. The
results validate its traditional use as a diuretic.
• Anti-Allergic: Inhibition
of early and late phase allergic reactions by Euphorbia hirta L:
Study demonstrated that E. hirta possessed significant activity to prevent
early and late phase allergic reactions.
• Anthelmintic: Anthelmintic
efficacy of the aqueous crude extract of Euphorbia hirta Linn in Nigerian
dogs: Extract of E. hirta Study reduced the fecal egg count of the helminths
and suggests a potential as an anthelmintic agent.
• Antihypertensive / ACE Inhibition:
Angiotensin converting enzyme inhibiting
and anti-dipsogenic activities of Euphorbia hirta extracts:
Study showed the extract from leaves and stems inhibited the activity
of angiotensin-converting enzyme (ACE).
• Anxiolytic:
Euphorbia hirta showed an activity profile different from that of benzodiazepines.
Study showed a central depressant and sedating effect with no hypnotic
or neuroleptic effects.
• Antidiarrheal: Antidiarrhoeic
activity of Euphorbia hirta extract and isolation of an active flavonoid
constituent: A flavonoid,
quercitin, with antidiarrheic activity was isolated.
