This family includes the largest genus in the world, Urtica, which is also known as stinging nettle. Stinging hairs are present on the lower surface of the leaves and beneath the stems of Urtica simensis, also known as the stinging nettle, herbal nettle that is dioecious, upright, and unbranched. For the treatment of conditions like gastritis, heart disease, diabetes, gonorrhea, and malaria, people employ various portions of Urtica simensis in a variety of ways in traditional medicine. The Urtica simensis leaves are rich in variety of active secondary phytochemical constituents including terpenoids, saponins, tannins, flavonoids, steroids, alkaloids, polyphenols, sterols, oxalate, and ascorbic acid (vitamin C). According to different reports, it possesses a variety of pharmacological properties, including antioxidant, antiproliferative, antidiabetic, cardioprotective, antiulcer, antibacterial, and antifungal actions. The current review summarizes published and unpublished information about the ethnobotanical, phytochemical, ethnopharmacological, and toxicological reports of Urtica simensis and summarizes all the

Rich.) Walp. (Menispermaceae) is traditionally used to treat wounds. Despite the fact that there have been in vitro studies and claims supporting wound healing, there has been no scientific data on the in vivo wound healing activities of the root of S. Abyssinica.Objective: The aim of the study was to evaluate the wound healing activity of 80% methanol root extract and solvent fractions of S. Abyssinica in mice.Methods: The roots of S. Abyssinica were air dried, ground and macerated by 80% methanol three times successively. The crude extract was fractionated by water, hexane and ethyl acetate separately. The acute dermal toxicity test was done by applying 2000 mg/kg of the 10% w/w crude extract. Wound healing activity of crude extract was evaluated on excision, incision and burn wound models, while the fractions were evaluated on excision wound model only.Results: In mice, an acute dermal toxicity test of 2000 mg/kg of the 10% w/w crude extract was found to be safe. The 10% w/w crude extract ointment (CEO) produced significant (p < 0.001) wound contraction from 4th to 16th post wounding days, and the 5% w/w CEO were significant (p < 0.01) wound contraction on 10th post wounding day as compared to simple ointment (SO) treated group on excision wound. On burn wound models, the CEO showed highly significant (p < 0.001) from the 6t
