Paracetamol (PCM) hepatotoxicity is related to reactive oxygen species (ROS) formation and excessive oxidative stress; natural antioxidant compounds have been tested as an alternative therapy. This study evaluated the hepatoprotective activity of an alcoholic extract of Boswellia ovalifoliolata (BO) bark against PCM-induced hepatotoxicity. BO extract also demonstrated antioxidant activity in vitro, as well as scavenger activity against 2, 2-diphenyl-1-picrylhydrazyl. Administration of PCM caused a significant increase in the release of transaminases, alkaline phosphatase, and lactate dehydrogenase in serum. Significant enhancement in hepatic lipid peroxidation and marked depletion in reduced glutathione were observed after parac intoxication with severe alterations in liver histology. BO treatment was able to mitigate hepatic damage induced by acute intoxication of PCM and showed a pronounced protective effect against lipid peroxidation, deviated serum enzymatic variables, and maintained glutathione status toward control. The results clearly demonstrate the hepatoprotective effect of BO against the toxicity induced by PCM.

One of the leading causes of death worldwide is cardiovascular disease, hence searching for a cure is an important endeavor. The totally safe, edible, and inexpensive Boswellia plant exudate, known as olibanum or frankincense, is considered to possess diverse medicinal values in traditional medicine and from recent biological studies. Investigating the cardioprotective and antioxidant activities of olibanum from a Boswellia species, family Bursearaceae, namely Boswellia carteri Birdw. was the aim of this study. Cardioprotective activity was evaluated using a model of myocardial infarction induced by isoprenaline (ISO), while antioxidant activity was tested adopting nitric oxide scavenging (NOS) and azino-bis-3-ethyl benzthiazoline-6-sulfonic acid (ABTS) assays. The results revealed a mild cardioprotective effect and weak antioxidant activity.
