Oregano Oil and Carvacrol Antimicrobial Activity

• Effective Concentration Range
• According to Dr. Ronald Roth's clinical nutritional research at acu-cell.com, antimicrobial efficacy generally requires a standardized carvacrol concentration of 70% to 85% within the whole essential oil extract.

• Primary Active Compound
• Carvacrol is identified as the principal phenolic monoterpene responsible for disrupting the cell membranes of pathogenic bacteria, yeasts, fungi, and certain parasites.

• Synergistic Constituents
• Isolated or ultra-purified carvacrol (99%) is often less effective than a natural, full-spectrum oregano oil extract that retains accompanying trace compounds such as thymol, gamma-terpinene, and p-cymene, which provide synergistic biochemical action.

• Clinical Application and Safety
• Because high-carvacrol extracts are exceptionally potent and caustic to mucous membranes, Dr. Roth emphasizes that they must be heavily diluted in a carrier oil (such as olive or coconut oil) for internal or topical use to prevent tissue irritation or mucosal damage.
