Labisia pumila (Blume) Fern.-Vill. synonym Marantodes pumilum (Blume) Kuntze is a flowering plant of the Primulaceae family. It is used traditionally by the Malay women to shrink the uterus, facilitate labor, improve menstrual irregularities and as post-partum medicine (Runi, 2000). The ethnopharmacological studies and clinical findings have illustrated that L. pumila possesses many biological functions, including phytoestrogenic, antimicrobial, anti-oxidative, anti-inflammatory properties and anti-aging (Choi et al., 2010;Nadia et al., 2012). Recent studies on L. pumila also demonstrated that it could also be used for osteoporosis, cardiovascular diseases, and metabolic disorders (Shuid et al., 2011). The ethnobotanical and therapeutic properties of L. pumila make it a potential source of novel medicine for the healing of wounds. Therefore, this study investigates the effectiveness of topical application of the aqueous extract of L. pumila on the rate of wound closure and the histology of the wound area.
Materials and Methods
Plant collection and extractionThe plant species were collected from their natural habitat in the rainforest of Taiping, Perak, Malaysia in October, 2014. Identification of the plant species was verified by a botanist from the Faculty of Science, Universiti Kebangsaan Malaysia (UKM). All voucher specimens were deposited in the Herbarium of UKM (voucher specimen number of L. pumila var. alata = UKMB 30006/SM 2622 and var. pumila = UKMB 30007/ SM s.n.). The standardized aqueous extraction method was used according to Jamal et al. (2003)
AbstractThe purpose of this study was to determine the wound healing effect of Labisia pumila in the ovariectomized rat model. Ninety-nine Sprague Dawley female rats equally divided into nine groups; where five were control groups, and four were treated groups. The dressing was changed daily, starting from the wound induction until complete healing. The percentage of wound contraction was measured on day 0, 2, 5, 8, 9, 10, 11, 12 and 13. Three rats were sacrificed from each group on day 2, 5 and 8 respectively for evaluating of histological assessments. Wounds dressed with extract showed considerable healing and significantly healed faster compared to all control groups (p<0.05). Moreover, histological analysis revealed remarkable reduction in the scar width correlated with the enhanced collagen content and fibroblast cells, accompanied by a reduction of inflammatory cells in the granulation tissues.In conclusion, L. pumila may promote wound healing in postmenopausal rat model.
