Anti- inflammatory action: The methanol extract of Crinum asiaticum bulb was evaluated for its anti-nociceptive properties on the pain induced by acetic acid and formalin in Swiss albino mice. Oral administration of bulb extract at a dose of 1.5g/kg & 2g/kg showed the highest inhibition 52.56% and 47.37%, respectively, at the 3rd hour of administration whereas at a dose of 1g/kg showed 37.5%inhibition at the 4th hour.

Anti- bacterial activity: Aqueous and ethanol extracts from the leaves of crinum asiaticum plants were  investigated for their antibacterial activity against gram negative bacteria Pseudomonas aeruginosa (ATCC10031) Klebsilla pneumoniae (ATCC 10031) and Escherichia coli  (ATCC 25922) and gram positive bacteria Staphylococcus aureus (ATCC 11632) and Bacillus subtilis (ATCC 23859) using the agar well diffusion, disc diffusion and broth dilution methods.

    Maybe there is a mistake?
    “Karma (Actions) – Kapha vata shamaka (reduces vitiated vata and pitta dosha).”
