  1. Can we administer milk thistle to our 9 years old Staffie who suddenly started fitting 3 weeks ago, 1 bad one lasting 15 minutes, 2 lesser ones lasting 3/4 minutes, and perhaps 4/5 minor ones without convulsions. His blood checks are all good, which perhaps points to a brain disease. Can we give him milk thistle in either tablet or milk form to help with possible side effects to the drugs?
