My Son Has Epilepsy And Is Currently On Lamictal. He

My son has epilepsy and is currently on Lamictal. He takes Aplrazolam prn when he (or we) can tell he is likely to have a seizure. He doen't have frequent seizures - anywhere from once every few months to 2 years. Lately, he has been having concerning memory problems. He is thinking about using a product called Protandim that has wonderful antioxidant properties. It is a combination of Milk Thistle, Bacopa, Turmeric, Ashwagandha and Green Tea. Do you see any possible interactions with these herbs and the meds he is taking?
