11 Kitchen Spices That Work Better Than Your Medicine Cabinet

9. Oregano — Antimicrobial and respiratory support

Oregano is a kitchen mainstay in many cuisines and carries compounds like carvacrol and thymol that have antimicrobial properties in lab studies. Traditional remedies use oregano for mild coughs and sore throats, and some people use oregano oil in diluted form for short-term, topical needs or inhalation with caution. Culinary oregano in sauces, roasted vegetables, and marinades adds flavor and mild protective properties without the risks of concentrated oils. If using oregano oil, do so diluted and follow product instructions — highly concentrated essential oils can be irritating and are not for internal use unless directed by a qualified practitioner. For everyday respiratory comfort, oregano tea or a steaming bowl with a little fresh oregano can be a gentle supportive ritual alongside rest and fluids.
