Description
Summary:Leucas lavandulaefolia has been traditionally used to treat wounds, rheumatism, migraines, diabetes, swelling and inflammation. This study aimed to determine the analgesic and anti-inflammatory activity of an ethanol extract of L. lavandulaefolia leaves. Analgesic activity was determined using the hot plate method, and anti-inflammatory activity based on carrageenan-induced rat paw oedema was determined using a plethysmometer. Each test used 25 male Wistar rats consisting of five treatment groups. Group I negative control was given Carboxymethyl Cellulose Sodium (Na CMC) 1%, Group II positive control was given sodium diclofenac dose 5.0 mg/kg Body weight (BW) for analgesic activity and aspirin dose 100 mg/kg BW for anti-inflammatory activity, and groups III–V (treatment groups) were given ethanol extract of L. lavandulaefolia leaves, with each dose at 200, 400 and 800 mg/kg BW. The results showed that the ethanol extract of L. lavandulaefolia leaves at a dose of 400 mg/kg BW had the highest analgesic activity percentage (22.85%) and no significant difference (p < 0.05) compared to the positive control (Diclofenac Na). Anti-inflammatory activity was highest at 800 mg/kg BW (percent inhibition 62.91%) and significantly different (p< 0.05) compared to the positive control (aspirin). This result indicates that the ethanol extract of L. lavandulaefolia leaves can be an alternative medicine for analgesics and inflammation.
