Previous studies conducted on the anti-inflammatory, antimicrobial and antioxidant effects of Matricaria chamomilla (chamomile) extract led us to study the effect of topical chamomile extract on burn wound healing in albino rats. Thirty male albino rats (250-300 g) were randomly divided into three groups, as control, vehicle, and treatment. Second-degree burning was induced in 20% of whole surface area of animal body by placing the back of animal into boiling water for 8s. Animals of control group received no treatment. Animals of vehicle and treatment groups were treated topically by olive oil and extract dissolved in olive oil twice a day respectively from the first day of burn induction to complete wound healing. The percentage of wound healing was calculated weekly. The results showed that there was significant difference (p < 0.05) between vehicle and treatment groups. So we concluded that the chamomile extract in the form of rubbing oil had a good potential for acceleration of burn wound healing in rats.
In this investigation, the effect of Matricaria chamomilla extract on linear incisional wound healing was studied. Thirty male Wistar rats were subjected to a linear 3 cm incision made over the skin of the back. The animals were randomly divided into three experimental groups, as control, olive oil, and treatment. Control group did not receive any drug or cold cream. Olive oil group received topical olive oil once a day from beginning of experiments to complete wound closure. Treatment group were treated topically by M. chamomilla extract dissolved in olive oil at the same time. For computing the percentage of wound healing, the area of the wound measured at the beginning of experiments and the next 2, 5, 8, 11, 14, 17, and 20 days. The percentage of wound healing was calculated by Walker formula after measurement of the wound area. Results showed that there were statistically significant differences between treatment and olive oil animals (p < 0.05) in most of the days. We conclude that the extract of M. chamomilla administered topically has wound healing potential in linear incisional wound model in rats.
Background: Few studies have evaluated the effect of Rosa damascena (R. damascena) on uterine smooth muscle contraction and dysmenorrhea; but, their results were inconsistent.
Background: Few past studies have indicated antispasmodic and anti-oxidative effects of some species of Rubiaceae. Objectives: This study aimed to investigate the effect of hydroalcoholic extract of Rubia tinctorum L. (madder) root on the rat-isolated aorta and possible protective effects against the damage caused by hyperglycemic environment. Methods: The isolated thoracic aorta ring (with or without endothelium) was treated with phenylephrine (10 -6 M) or KCl (80 mM)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
