Essential oil question

I use sweet orange essential oil (Citrus sinensis), and I feel like that was the specific one I was told to use for goats, but I can’t remember where I learned about it! I’m interested to hear more about this too.

So I believe.. naval oranges are a type of sweet orange? So Citrus sinensis again, and sweet oranges actually originated from a cross of mandarin oranges and pomelos to begin with? So then sweet oranges are looking good if those peels are working for you! And I’m using the oil with good results. I’m super curious what’s different about bitter orange.

I did a little more research about bitter orange (Citrus aurantium). I guess that instead of bitter orange oil you may find Bergamot (Citrus bergamia) instead, because the plant is likely a cross between bitter orange and lemon. I’m not finding bitter orange oil sold in the places I checked, but Bergamot is very common, so maybe that would be another option instead of bitter orange. I did find an article that explains the differences between them.

They do say that Bergamot had been used traditionally for parasitic infections. Has anyone tried Bergamot for their goats?
