Everyone is clowning on OP but there have been some studies done that suggest there may be some benefits from saffron in mood disorders and possibly ADHD. It's not strong evidence but it seems to be taken seriously in medical circles (i.e. not just dismissed as home remedy bs). There seems to be some mechanism for it effecting neurochemistry.

OP, it definitely won't have anywhere near the efficacy of proper medication but as you say its worth a try to see if you get some benefit. It seems like it can at least help with sleep regulation, if thats an issue. Let us know if you notice any effects over time.
