(2) Flower juice for sinusitis. (3) Flower oil used for headaches and sinusitis. (4) Juice or decoction of flowers and leaves used for intestinal worms in children. (5) Leaves rubbed over scorpion bites.
Study of methanol extract and methanol fraction of LA flowers showed good antibacterial activity; alkaloidal residue showed maximum activity.
• Antioxidant / Prostaglandin Inhibition:
Extract study showed prostaglandin inhibition and antioxidant activity. Study yielded eight lignans and four flavonoids.
Study showed hepatoprotective activity of LA attributed to the unconfirmed
presence of flavonoids.
• Antinociceptive / Antioxidant: Ethanolic extract of L aspera showed significant writhing inhibition and significant free radical scavenging activity and significant lethality to brine shrimp with an LC50 value.
• Larvicidal: Study
of crude extracts of L aspera showed good
larvicidal activity against the larvae of Culex quinquefasciatus and
• Anti-inflammatory: Study
showed L aspera to have significant anti-inflammatory effect in acute and subacute inflammation, more effective than acetylsalicylic acid and less than phenylbutazone.
• Alkaloid / Nicotine: Study
yielded a liquid alkaloid from the aerial parts of L aspera, identified as nicotine, giving a characteristic tobacco-like odor. The insecticidal property of the herb could be due to the presence of nicotine.
• Diterpenes / Inhibition of Prostaglandin-Induced Contractions: Study
on the inhibitory activity on prostaglandin-induced contraction in guinea pig ileum yielded four new diterpenes (leucasperones A and B and lecasperols A and B) and three new isopimarane glycosides (leucasperosides A, B, and C) together with known compounds. Leucasperone A, leucasperosides A and B, and linifolioside (known compound) showed inhibition of prostaglandin-induced contractions.
