Medicinal uses - WIKEPEDIA
In old medicinal literature, vanilla is described as an aphrodisiac and a remedy for fevers. These purported uses have never been scientifically proven, but it has been shown that vanilla does increase levels of catecholamines (including adrenaline), and as such can also be considered mildly addictive.
