Lemongrass has a lemony(kinda tart/sweet) scent.
Powers: Repels snakes, Lust, Psychic Powers (::Grin::: it also keeps mosquitoes away hehehehe)
If you plant lemongrass you will find the snakes will be no more, they don't like the smell nor the taste/touch of lemon grass.
as an infusion or essense oil this makes a good meditation aid to help develop psychic powers.
(although I don't suggest taking anything ANY of the unknown Herbs internally, as I am not a DR. due to allergies and such check with a physician first ALWAYS)
