Oregano (Origanum vulgare) is a potent medicinal herb whose volatile essential oil contains exceptionally high levels of carvacrol and thymol—two phenolic monoterpenes with proven, broad-spectrum antimicrobial properties. Carvacrol and thymol directly disrupt the cell membranes of bacteria, fungi, and parasites, causing cell leakage and death. It serves as an incredibly powerful natural intestinal disinfectant and respiratory shield.
Educational information only — never stop or change a prescribed medication without talking to your prescriber first.
CRITICAL: Concentrated oil of oregano is extremely hot and can cause chemical burns to mucous membranes if taken undiluted; never swallow pure, undiluted oil. Avoid during pregnancy, as it can stimulate uterine blood flow. High or prolonged doses can disrupt beneficial gut flora (take with probiotics).
