I think, that there are quite a few oils [Thieves,Oregano, Thyme,Basil,Peppermint,Frankincense ,Orange,Di-gize,G.L.F. etc...just to name a few] who don't have those white labels on them, but are quite safe to take internally.
Any of the citrus oils are quite safe to take with/in water and make water taste great as well.
I also found adding Thieves and a citrus oil to food makes it taste nicer.
Thyme and Basil into gravy is also nice.
For a bad cold I found that using Thyme, Oregano and Clove in a OO veg. caps. really helped.
When I've been rather busy and get to tired, I found using Longevity in water [about 2 drops per 2literof water over a day] really helped.
Peppermint is wonderful to put into a flask with warm /hot water as a refreshing hot drink [even my 5 year old really enjoyed it].
It's great to hear that your mum is improving, Rachel....can't see that Thieves would do any harm for your mum to take to give her immune system a boost.
Clove and Longevity would be a great help to the immune system as well, as they are both very high on antioxidants.
Young Living are having a leaflet "Scents & Scentsability", which has got a page in it 'oils safe for ingestion'....some surprises there....Susie,Jasmine is included there, but no Thieves [even so I 've taken it for a while [so has my 5 year old] and many others I know taken it....but perhaps it's a little out of date...perhaps something to try to find out on 12/5.....[?]
