Sarapin

Nope not illegal. Used in an anti-inflammatory capacity alongside steroids in sacroiliac and DSP injections. Its use is very clinician dependant, those who have never used it may see no need, those who have seem to like it a lot.
 
It has been used successfully in overweight and laminitis prone horses for that purpose. If it is a competition horse, be aware it is on the controlled substance list and there is no known detection time for it.
