| Summary: | The traditional use of <i>Aloe</i> spp. for the purpose of wound healing has a long history and is widespread internationally. Recently, a hybrid aloe plant (<i>Aloe muth-muth</i>) has been cultivated by cross pollination between <i>Aloe vera</i> and <i>Aloe ferox</i>. The <i>Aloe muth-muth</i> plant has not yet been investigated for medicinal properties and provides an opportunity for potential biological activity, including wound healing. The aim of this study was to investigate the in vitro wound healing effects of both <i>Aloe muth-muth</i> gel and whole leaf material with the use of the immortalized human keratinocyte (HaCaT) cell line. Cell viability was conducted using methyl thiazolyl tetrazolium (MTT) assays. In vitro wound healing was tested on HaCaT cells using an established scratch assay method. The effect of <i>Aloe muth-muth</i> gel material on HaCaT cell migration was also investigated. <i>Aloe muth-muth</i> gel material exhibited statistically significantly (<i>p</i> < 0.05) higher percentage wound closure compared to the control at all three concentrations investigated. These findings confirm that this newly cultivated species, <i>Aloe muth-muth</i>, also possesses wound healing activity corresponding to that reported for the two species it is derived from, namely, <i>Aloe vera</i> and <i>Aloe ferox</i>. Therefore, <i>Aloe muth-muth</i> has the potential to be used in future wound therapeutics.
