VALERIAN

valerian (Valeriana officinalis) is a perennial herb native to europe and asia (and has been naturalized in the united states) which has been used medicinally since at least as early as ancient rome, possibly earlier. through antiquity,  dried valerian root has been used to treat insomnia, heart palpitations and gastrointestinal upset, and is still used today. that probably means it works, right?
