I do not believe that matters. What matters is what tests positive. Either traumeel leaves no discernable amounts after x hours (unlikely) or what it does leave is not on the list of prohibited substances.
USEF is different in that it has a helpful list of what is allowed and prohibited and goes out of its way to educate members. FEI has a very short list with w/d timeframes for some more commonly used drugs, but make no guarantee that your horse will be clean under that timeline. It also takes some sleuthing to find that list. They also have an extensive list of hell no not ever drugs and āacceptableā drugs where no timeline is given (my personal fave is Diclofenac cream, leaving me to wonder how long before an event should I stop using it on ME to avoid a positive test on my horse). Then there are substances that just arenāt on the list. I stopped buying Sore No. More years ago becauseā¦ usef list. I never even thought to check and see whether those ingredients are on the FEI list, even though I know the lists are not the same.
