Some vague literature suggested Ginkgo was useful for treating ADHD. From personal experience, it outperformed standard NRI's.
I initially thought the blocking of certain GABA-A receptors was merely a side effect. Now I've read that other substances useful for the illness (Panax Ginseng, and in particular Oroxylin A) which do exactly the same thing.
I now suspect that classic treatments like Ritalin may exert some beneficial effect by inhibiting this receptor.
Or am I just talking a load of bollocks?
