Re: Clove oil

I was just about to point out that FDA note as well,
 The guidance document basically states that while
clove oil and its components are considered safe as food
additives, if you use it on fish which could be eaten
by people there are still safety concerns ( as viewed by the regulations)
And you are not allowed to do that.

Welcome to the world of the FDA, where the same rules that
apply to large drug companies and the development of human drugs,
also apply to minor applications of animal 'drugs'. And basically
anything is considered a drug if it effects the fish in almost anyway
and not just the treatment of disease.
Fortunately 'ice' and a few other 'drugs' were given exemptions
from further regulation several years ago.

The folks in FDA/CVM try to help as best they can, but the
regulations they are forced to operate under can make the approval
process a long and tedious journey and it takes lots of patience to
see it through. I don't know the status of 'clove oil' but I would
suspect it may still be a few years way from full approval
