Comparative anti-inflammatory and analgesic activities of leaf powder and decoction of Chirabilva [Holoptelea integrifolia (Roxb.) Planch].

BACKGROUND

Ethno-medical claims indicate that leaf of Holoptelea integrifolia (Roxb.) Planch is being used in pain, inflammatory conditions by the Koya tribes.

OBJECTIVE

To evaluate and compare the anti-inflammatory and analgesic activity of leaves of H. integrifolia in powder and decoction forms.

METHODS

The leaves of H. integrifolia were made into powder and decoction form using guidelines mentioned in Ayurvedic Pharmacopeia of India. The anti-inflammatory activity of test drug was evaluated against carrageenan and formalin induced paw edema and analgesic activity with formalin induced paw licking and tail flick response using Wistar albino rats.

RESULTS

Administration of leaf powder showed insignificant inhibition of carrageenan induced paw edema at 1 h (21.62%) compared to the control group. Administration of decoction of leaves showed insignificant inhibition of carrageenan induced paw edema at 1 h (18.12%) and 3 h (9.78%). Administration of leaf powder decreased the paw edema at 24 h (37.65%) and 48 h (66.30%) while treatment with leaf decoction showed apparent decrease in paw edema at 24 h (13.68%) and 48 h (52.42%) but failed to reach at significant level of formalin induced paw edema in rats. The test drugs did not produce any effect on radiant heat induced pain in rats and formalin induced paw licking response.

CONCLUSIONS

Leaf decoction of H. integrifolia has better anti-inflammatory activity than leaf powder while they have not shown significant analgesic effects in both the experimental models.
