while there have been no major interactions reported with this combonation, because everyone is different it is hard to say. do u wanna take valerian root to help u sleep? or for another reason? if u have sleeping problems due to the adderall, you can try melatonin. synthetic melatonin is great and because it is not an herbal product, you are guaranteed to get what u want...like if u buy 3mg. melatonin, that is a guaranteed potency. unlike "natural" melatonin that comes from animal sources and herbal valerian. you cannot be sure the potency of it. natrol makes a good vegetarian "synthetic" form which is pure.
i take 1.5mg. melatonin 2 hours before bedtime and wow what a difference..without daytime drowsiness or hangover effect. also lifts my mood. before i was taking 3mg nightly and experienced daytime drowsiness despite my very high tolerance to drugs.
ginko is a great herb....but because it improves circulation..becareful of increased heart rate which usually isn't a problem. 220-240mg. taken daily in divided doses is the best range...takes about 4 weeks to feel the full benefit. to make sure you are buying quality ginko..buy from a quality company. and i don't mean GNC..they are a rip off. the vitamin shoppe is an excellent store (in many cities) and website to buy high quality supplements/herbs at a cheap price...
hope i helped some!
