As a pharmacy student
( as in I don't know everything, don't hate on me ) I've heard of Emu Oil (quite briefly, we don't focus much on that kind of products ) but it is indeed great for dry skin. It is even recommended for freshly made tattoos because of how hydratating it is
. As for join paint, Emu Oil isn't an anti-inflamatory per say but it is shown to help join paint when taking orally, topically I'm not sure. Fact is most studies are on animals and it does work but we have no proof on humans just yet.
If you wanna try it : go for the purest possible not for the " emu oil based cream " that might contain 0.05% of oil or something. ASK YOUR PHARMACIST, if you take any medication. Yes even natural products and creams etc. can interact with medication.
And I apologize if i use words that don't exist or something, I study in french.
