I know.. I'm an eejit. I get dermatitus and pick my scalp in my sleep so for years I've had open cuts on my scalp. I smothered about half a bottle of neat teatree oil on there and let sit for 5 mins before washing off. Have since read that's it's highly toxic when ingested. Although I didnt ingest it I'm worried it's got into bloodstream through open cuts. Has anyone else used neat on cuts. Urgh, not sure if I'm just having a weird anxiety attack or if this is a genuine risk. Feeling really stupid.
