• feather
• rosemary oil
• shell
• stone
• onion
• horseshoe ( if you have one )

Write the name of the person you wish to heal on the onion.
Plant the onion bulb in a pot or garden, and put a stone to the north, three drops of rosemary oil to the south, a shell to the west and a feather to the east. Cover the objects with the soil.

Place the pot on a horseshoe, or place a horseshoe close by if the bulb is planted in the garden.

This spell uses the strength of Mars, the god of war -- both the onion and the horse are governed by Mars -- to win the battle over the illness.
