Pycnogenol and Alternative Treatments


"Can you tell me about Pycnogenol and Maquelier's OPC (pine bark extract and grape seed oil extract)? I have heard many good things about these treatments but would like to know more regarding any side effects."

Dr. Larry Silver specializes in treating children with attention deficit disorder (ADHD).

The scientific literature shows that neither of the products you list helps individuals with ADHD. Manufacturer trying to sell the products provide the only literature available suggesting that they work. I discourage you from considering either. If you want a summary of the literature on these proposed alternative therapies, you might read the chapter on such therapies in my book (either The Misunderstood Child or Dr. Larry Silver's Advice to Parents on ADHD).

Larry Silver, M.D., is the author of Dr. Larry Silver's Advice to Parents on AD/HD and The Misunderstood Child: Understanding and Coping with Your Child's Learning Disabilities. He is also a clinical professor of psychiatry at Georgetown Medical Center in Washington, D.C.
