@glitterbag,
Galangal oil is a medicinal item for many. Said to help with sleep, better the digestive system, right depress. For some, it's an aphrodisiac. Made from the galangal plant. There is also galangal tea. It gets a lot of use in traditional Chinese medical matters.
(just don't confuse it with ginger. Similar appearance, not the same benefits)
I first heard of it from my grandmother. Apparently her family used it when she was growing up.
They also had horehound drops - a sort of candy type thing with medical benefits.
