Sorry but water and oil are not the same thing.people say that but use that redflag for bs term "toxins", but every serious look at it says it does the same thing water does. And the ancient texts about the practice often label it as a substitute fos water based concoctions. But if it works for you the only harm is fattening others wallets.
They can both have similar benefits, such as "rinsing" in general, the particulate matter from the oral cavity, but they in no way, shape or form "do the same thing".
Fat is a necessary constituent of the human diet, and some people don't mind using healthy oils to coat their oral cavity and then swallow it to gain a few more molecules of said oil.
And I see no reference to "toxins" here at all; so don't know what that is about.
