Just to complicate things, it turns out that yucca is allowed by USEF  
- I was curious, so I sent off an email.  Their reply is below.  While  
AERC doesn't need to operate under USEF rules, what about endurance  
riders in FEI rides?  Or is that yet another set of drug rules?

Dear Elizabeth,

Yucca is permitted under the Therapeutic Substance Provision of the  
USEF Drugs and Medications Rule.
