There are many herbal supplements that do indeed increase focus/concentration. However no herb is required to demonstrate that it is safe and effective by the FDA and has thousands of patients in controlled studies to prove it. Herbs differ in purity, amount from dose to dose and serious side effects are not required to be listed on the package insert. I have had patients take sudafed before with similar results. Many of these herbs have active ingredients known to cause heart arrthymias and other serious problems. Taking an herb is not any more natural than making a drug by purifying it in a lab (even 'natural' remedies have to be collected, washed, the active ingredient isolated and added to a benign filler, etc). You are taking a big risk with your child's health.
