Evaluation of Antimicrobial and Wound Healing Potential of Justicia flava and Lannea welwitschii

Table 3

Antimicrobial activity of methanol leaf extracts of J. flava (JFL) and L. welwitschii (LWL) by agar diffusion method. Mean zones of growth inhibition (plus diameter of well) are mean (mm) of 3 independent experiments, mean ± SD, replicates, and diameter of well/cup = 8 mm.
