I use this orally for dental issues, I apply this thick salve-like oil with a cotton-tipped swab. It is well-infused with therapeutic ozone and that's why is it so thick compared to other olive oils infused with ozone. It has helped me with reducing oral infection. I believe the ozone is gone within 30 seconds, so I swish it around that long and then spit. Also good for skin application. Good item to have on hand at home in your medicine cabinet.
