Romany cure for depression

This spell is from the book, "The Good Spell Book: Love Charms, Magical Cures, and Other Practical Sorcery," by Gillian Kemp, Published by Little, Brown, & Company 1997.

Peel several cloves of garlic and place them in a saucer. Pour white vinegar over the garlic until they are half way immersed in it. Place the saucer beside your bed while you sleep. The garlic is said to turn pink, because of the negative energy it absorbs.

The cloves should be buried in the morning and replaced by fresh cloves at night.
