The Anti-inflammatory Effect of Honeysuckle Flowers (Lonicera japonica Thunb., Caprifoliaceae) in Combination with Oroxylum Indicum (Oroxylum indicum Vent. Bignoniaceae)

This study investigates the anti-inflammatory effect of the honeysuckle flower in combination with Oroxylum indicum in search of a new kind of anti-inflammatory therapy drugs with stronger anti-inflammatory effects and without unwanted adverse reactions. The study results show that a honeysuckle flower dose of 0.72 g/kg/day, Oroxylum indicum dose of 1.2 g/kg/day together with honeysuckle flower combined with Oroxylum indicum with 1:1 ratio had an acute anti-inflammatory effect on the white rat on a mouse Leg Edema Model with carrageenin and the model causing mouse peritonitis. The results also show that a honeysuckle flower dose of 1.44 g/kg/day, Oroxylum indicum the dose of 2.4 g/kg/day together with honeysuckle flower combined with Oroxylum indicum with 1:1 ratio had a chronic anti-inflammation effect on the white mouse on the model causing chronic inflammation of the granuloma. These results open up a subsequent research direction on the possibility of combining various anti-inflammatory medicinal herbs to obtain better anti-inflammatory efficacy and contribute to the promoting of the effect of the available domestic medicinal resources.
