Though extracting oils by steam distillation and other methods is almost prohibitively
expensive, we are spared this cost by the wide availability of essential
oils and synthetics on the market today. Many so-called “essential oils” are
actually synthetic; this does not negate their use in magic, however. If they
smell good, use them.
Though oils aren’t covered in this book, a list of them by their uses, and
commercial suppliers of oils, can be found in the Tables & Appendices.
Essential oils are used in numerous ways. They are worn on the body,
rubbed onto candles, dabbed onto sachets and poppets, added to baths,
burned on charcoal blocks, and smeared onto roots.
