You can never have too many candles or too much salt. To protect your home against ill will. Place a ring of salt around the house so no evil can cross. Use sage or rosemary smudges to cleanse the house from evil spirits or negative energy. Use apples that have been halved to show the natural pentagram in the centre and place laurel leaves (bay leaves) across the apple half and place them outside of a doorway to prevent any evil from entering. (it's organic so Mother Nature will take care of the apple or any little hungry critters)
Keep Thyme, Rosemary, Salt, Parsley, Bay Leaves on hand at all times.
