Lemongrass is bound to Mercury and air.  It is said to repel dragons and serpents, and is burned, bathed in, or carried on the person for lust, fidelity, honesty, growth, strength, psychic powers, and purification. 

Plant Lemongrass around the home to repel serpent energy.  Drink a Tea to aid in psychic abilities and divination.  Carry it in a sachet or charm to attract the object of your desire and to bring honesty to your relationships.  Burn as an incense for strength and purification.  Put a handful of leaves in a mesh bag and place under the tap water for a purification bath, and to attract and keep a lover.
