Is this tea tree oil food grade and safe for oral-care use?
Tea tree oil is not a food-flavoring oil in the traditional sense — it is primarily used externally. For oral-care applications (toothpaste, mouthwash), use only highly purified, low-cineole lots at very low concentrations and with formulator guidance.
