The topic of ingesting essential oils is a controversial subject with varying opinions depending on whom you ask. One thing I know for sure is there is no way I would ingest any oil without knowing it was a from a trusted source and has been tested for any toxic or synthetic substances. Many of the essential oils that can be bought at the local Walmart or many of your other outlet stores are not always 100% pure! Amazon isn’t actually a trusted source either for essential oils.
That being said, there are still many precautions to be taken if you are considering ingesting essential oils from a trusted source. People can have an adverse reaction to ingesting certain oils or may not be responsible in the amount of oil they consume. Certain oils have been known to cause toxicity in the liver or the body and should be avoided at all costs!
Of course cooking with certain essential oils has been done for years safely. Humans ingesting plants as well as extracts containing essential oils isn’t a new concept and some would argue has been going on for hundreds of years. Ingesting one or two drops of an oil also isn’t the same as ingesting a small bottle either! Remember essential oils are highly concentrated and there is a whole lot of plant in one drop of essential oil. I am not arguing for or against ingesting essential oils. Please do your own research and consult a doctor when needed.
Many essential oils are listed as GRAS (Generally Recognized As Safe) by the FDA for oral consumption. Here is a link to that source: https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?fr=182.20
