Background: Clerodendrum inerme is a medicinal plant which exhibited many pharmacological effects. However, wound healing property of this plant has not been investigated. Objective: The present study was designed to evaluate wound healing and antimicrobial activities of C. inerme leaves using the in vitro model with Human keratinocytes (HaCaT). Methods: Cytotoxicity and wound healing effects were determined by MTT and scratch wound healing assay. Antimicrobial activities against cutaneous flora and clinical isolates of bacteria were investigated by broth microdilution assay. Results: The results showed that the water extract of C. inerme leaves did not exhibit cytotoxic effects on HaCaT cells, while ethanol extracts at higher concentrations significantly decreased cell growth with an IC50 value of 386.8 {\textpm} 87.1 μg/mL. The water extract and the lowest concentration (6.25 μg/mL) of the ethanol extract significantly increased percentage of wound closure compared with the untreated group. The water and ethanol extracts of C. inerme displayed a broad spectrum of antibacterial activity, inhibiting growth of Staphylococcus aureus, Staphylococcus.epidermidis, Escherichia coli, and Pseudomonas aeruginosa. The water extract displayed remarkable activity against methicillin-resistant S. aureus with MIC and MBC values ranging from 0.39 to 1.56 μg/mL. Notably, it provided stronger antibacterial activity than vancomycin and also showed antifungal activity against C. albicans. Conclusion: This study confirms the potential of C. inerme leaves for wound healing and antimicrobial therapy and supports the continued utilization of C. inerme leaves in traditional medicine. Further studies are needed to clarify the molecular mechanisms through which it exerts such biological effects.

Background: Wound healing is a fundamental response to injured tissue that results in the restoration of tissue integrity. One of the famous herbs that promote wound healing is Aloe vera. Despite well known for its therapeutic effect, several studies reported inconclusive evidence regarding this. Besides, lack of evidence to postulate the superior effect of two components of Aloe vera which are the precipitate and supernatant. Objective: Study compares the effects of precipitate and supernatant in promoting tissue repair. Evaluation takes place by using optical Coherence Tomography (OCT) and is comparable with histopathology study. Methods: Twelve male mice were randomly divided into four groups (precipitate, supernatant, control 50\% ethanol, and normal). 200 mg of Aloe vera was extracted. A standardized 2 cm longitudinal incision wound was created. All mice were given topical Aloe vera, 0.5 g each, once daily and assessment of wound surface was performed using OCT. The animals were sacrificed on day 10 to evaluate histopathologically. Results: R parameter from the OCT was utilized to analyze the data. There is no significant difference in the treatment effect between Aloe vera treated group and control on day 10 post-injury. Treated animals with precipitate did not differ significantly from supernatant treated group. Nevertheless, from histopathology analysis, precipitate showed better wound reepithelialisation, collagen formation and angionesis despite having numerous inflammatory cells. Conclusion: OCT using R parameter is not the best choice to detect wound healing. Nevertheless, from histopathological perspective, Aloe vera accelerates wound healing and precipitate Aloe vera gel does have a superior effect from supernatant in promoting wound healing.

Objective: In the present study, we examined the effect of Aristolochia bracteolata extract on Human dermal fibroblast (HDF) and Human keratinocyte cell line (HaCaT) proliferation and migration during in vitro wound healing and its underlying mechanism. Method: A. bracteolata was collected and extracted using methanol. Cytotoxiciy effect of plant extract was determined by MTT assay in HDF and HaCaT. In vitro Scratch assay determined the effect of plant extracts on migration of cells and its underlying mechanism was determined by RT-PCR analysis. Result: The plant extract of A. bracteolata selectively inhibited proliferation of both the cells at higher concentration (\>100 \μg/mL) and at lower concentrations (\<25 \μg/mL), it exhibited linear and dose-dependent cell proliferation. IC50 value was 87.60\±1.67 \μg/mL for HDF and 85.50\±1.65 \μg/mL after 24 h treatment. In vitro scratch wound healing studies showed wound closure of 50.38\%\±1.39 and 69.81\%\±1.89 at a concentration of 25 \μg/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 A. bracteolata has a strong inhibitory effect on the production of NO and tumor necrosis factor-\α (TNF-\α). The plant extract of A. bracteolata 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. A. bracteolata 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. Conclusion: Thus, the present investigation scientifically validates the use of A. bracteolata in wound healing.

Objective:Butea monosperma, Barleria prionitis, Casuarina equisetifolia, Dalbergia sissoo, and Lagenaria siceraria are reported to possess anti-acne, anti-infl ammatory, anti-ulcer, and wound healing activity. The present work is aimed at evaluating the wound healing potential of these plant materials in acne vulgaris. Methodology: Individual gel formulations containing extracts of the above mentioned drugs and their polyherbal gels were evaluated by excision and incision wound model (in vivo) in Sprague Dawley rats. Results: The individual gel formulations showed signifi cant reduction in wound size when compared with the untreated group. The rates of wound closure after the application of the gels were compared with the untreated wounds. The polyherbal formulation containing all the extracts was found to be more benefi cial when compared to remaining treated groups. Healing under scab and formation of normal epithelial cells were better than other individual formulations. As well as vascular changes, cellular infi ltration, and necrosis were found less. Conclusion: From the results, it may be concluded that the plants are endowed with signifi cant wound healing activity, thereby justifying its traditional medicinal use in acne vulgaris as a separate entity and in combination. Chemical components such as tannins, fl avonoids, saponins, and alkaloids present in the extracts can be responsible for the foresaid activity.
