TL;DR: Investigation of the most potent chloroform extract from an autochthonous sage population grown in the submediterranean climatic region of Slovenia revealed ursolic acid as the main component involved in its anti-inflammatory activity.

TL;DR: Increased levels of lipid peroxidation measured as 2-thiobarbituric acid reactive substances (TBARS) indicative of oxidative stress in diabetic rats were also normalized by treatment with the extract, indicating increased metabolization of glucose in treated rats.

TL;DR: In this article, the authors compared the antimalarial activity of seven plant extracts traditionally used by the Isoceno-Guarani, a native community living in the Bolivian Chaco.

TL;DR: Data will be presented in this context, outlining how adulteration, inappropriate formulation, or lack of understanding of plant and drug interactions have led to adverse reactions that are sometimes life-threatening or lethal.

TL;DR: The results indicate that, at least part of chronic stress-induced pathology may be due to oxidative stress, which is mitigated by WSG, lending support to the clinical use of the plant as an antistress adaptogen.
