Today is St. Nininan's Day. His plant was the herb southerwood, a form of wormwood. Also known as "Lad's Love," this plant is believed to fan the flames of passion. This spell is best done on St. Ninian's Day or when the Moon is waxing.
Start by drawing a bath. Place a muslin bag holding the leaves of the southernwood in the water. LIght a new, red candle somewhere near the tub, and next to it place a ruby, a red jasper, and a garnet. Allow the powers of the herb and the stones, and the red energy of the candle to enter into every cell of you. Repeat this ritual as often as you wish during a waxing Moon.
