Biologically active supplements (BAS) based on plant material, possessing a wide range of beneficial properties (antioxidant, anti-inflammatory, antimicrobial, etc.), are becoming increasingly popular worldwide. Such supplements are readily available and can be used without consulting a healthcare professional. Consequently, the extent of their use is underestimated by doctors. Plant hepatotoxicity is not uncommon, but the frequency and manifestation are not sufficiently characterized. This study is dedicated to investigating the hepatotoxicity of trans-coric acid isolated from the root culture of Scutellaria baicalensis in in vivo experiments. This work aims to evaluate the hepatotoxicity of trans-coric acid on male rats at doses of 50.0 and 100.0 mg/kg. During the experiment, it was found that trans-coric acid, isolated from the root culture extract of Scutellaria baicalensis, does not induce hepatotoxicity in the presented doses in model animals with 14-day intragastric administration. Thus, this study demonstrates that trans-coric acid can be safely used as a component of BAS for the prevention of chronic diseases, thereby promoting healthy aging
