Opinions on Valerian as a calming supplement?
 

Hi,

I am wondering if any of you have tried Valerian as a calming supplement on your horses? My horse is currently on Smartcalm Ultra in the AM and Quietex in the evening, I was thinking about putting him on this instead:
Confidence Plus - Herbal Supplements from SmartPak Equine

I know valerian is illegal for showing, but we're just doing lessons/trail riding at the moment.

Any thoughts?

Thanks!

:)
