Like you say, some oil stays on your teeth and under your tongue, so this method of ingestion
actually combines sublingual processing of the oil (ala Sativex and other under-the-tongue sprays
and tinctures that people use) and processing in the stomach and intestines. The main thing is to
get the oil in your stomach. So, if you have oil with a not-so-good taste, you can put in a piece
of bread or banana etc. (or cigarette paper, if you like to eat the chemicals in it), fold it over and
swallow it like a pill and flush it with water or tea or whatever you like. Brush your teeth with
oil after say ten minutes or so, it will help with oral hygiene, too. Many oils have a delicious taste
(especially when the starting material is not ground up and when alcohol isn’t used to produce
the oil. Chlorophyll usually tastes bad and can cause a lot of discomfort, even when used topically
- dark oils will stain your clothes, you don’t really want or need that.)
