Cytotoxiciy effect of plant extract was determined by MTT assay in HDF and HaCaT. &lt;em&gt;In vitro&lt;/em&gt; Scratch assay determined the effect of plant extracts on migration of cells and its underlying mechanism was determined by RT-PCR analysis. &lt;strong&gt;Result:&lt;/strong&gt; The plant extract of &lt;em&gt;A. bracteolata&lt;/em&gt; selectively inhibited proliferation of both the cells at higher concentration (&amp;gt;100 &amp;mu;g/mL) and at lower concentrations (&amp;lt;25 &amp;mu;g/mL), it exhibited linear and dose-dependent cell proliferation. IC&lt;sub&gt;50&lt;/sub&gt; value was 87.60&amp;plusmn;1.67 &amp;mu;g/mL for HDF and 85.50&amp;plusmn;1.65 &amp;mu;g/mL after 24 h treatment. &lt;em&gt;In vitro&lt;/em&gt; scratch wound healing studies showed wound closure of 50.38%&amp;plusmn;1.39 and 69.81%&amp;plusmn;1.89 at a concentration of 25 &amp;mu;g/mL after 24 h and 48 h, respectively. The extract was tested for anti-inflammatory activity by determination of inhibitory activity on lipopolysaccharide (LPS) induced nitric oxide (NO) production in RAW 264.7 cell lines. We found that &lt;em&gt;A. bracteolata&lt;/em&gt; has a strong inhibitory effect on the production of NO and tumor necrosis factor-&amp;alpha; (TNF-&amp;alpha;). The plant extract of &lt;em&gt;A. bracteolata&lt;/em&gt; inhibited inducible nitric oxide synthase (iNOS) gene expression by lipopolysaccharide (LPS). To explore the mechanism responsible for the inhibition of iNOS, gene expression was analyzed by Real- Time PCR. &lt;em&gt;A. bracteolata&lt;/em&gt; showed a decrease in the expression of pro-inflammatory cytokine mRNA in a concentration-dependent manner. Treatment with the plant extract resulted in enhanced expression of Collagen 1 a (I) and Collagen IV in HDFs by regulating the mRNA levels of extracellular matrix (ECM) proteins and Matrix metalloproteinase-2. &lt;strong&gt;Conclusion:&lt;/strong&gt; Thus, the present investigation scientifically validates the use of &lt;em&gt;A. bracteolata &lt;/em&gt;in wound healing.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6s</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">s129</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Dinesh Murugan Girija&lt;sup&gt;1&lt;/sup&gt;, Mangathayaru Kalachaveedu&lt;sup&gt;2&lt;/sup&gt;*, Rajasekaran Subbarayan&lt;sup&gt;3&lt;/sup&gt;, Preethi Jenifer&lt;sup&gt;2&lt;/sup&gt;, Suresh Ranga Rao&lt;sup&gt;4 &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
