Oregano (Origanum vulgare) is a culinary herb that has drawn scientific interest for its rich concentration of bioactive compounds, particularly carvacrol and rosmarinic acid. Research suggests that oregano possesses notable antioxidant properties, with studies indicating its phenolic compounds may help reduce oxidative stress and support the body's natural defense systems. Laboratory and preliminary clinical research have also explored oregano's antimicrobial activity against a range of bacteria and fungi, as well as its potential anti-inflammatory effects, though much of this evidence comes from in vitro or animal studies rather than large-scale human trials. Traditionally enjoyed as a dried herb or brewed into tea, oregano continues to be investigated for its role in digestive comfort and overall wellness, making it a subject of growing interest in herbal supplement research.
