  1. Each value is mean ± S.E.M of six rats. *p < 0.05, compared with control using Dunnett’s t (two-sided) test. Values given in parentheses represent the percentage inhibition of edema volume at each hour as compared to the control group. **Amount isolated from 200 mg/kg of CWE TM02 using sephadex G-50 gel filtration chromatography. CWE-cold water extract; HWE-hot water extract; ME-methanol extract; HMW-high molecular weight fraction; MMW-medium molecular weight fraction; LMW-low molecular weight fraction.
