Some folks sell you talcum powder with a few drops of essential oils mixed in it but that is not how the old time sorcerers did it.
I offer you a bamba wood based sprinkling powders that use the choicest herbs and root cuttings mixed in with the best pure essential oils I can acquire. This gives you the benefit of having the most accurate incense/powder that you can buy at this price.
For use a pinch is all you need. If you desire to know specifics on how to use each formula, you should check out my guide, "Moloch's Guide to Using Sorcery Formulas" (Available from LuLu.com). Suffice to say though that powders are sneaky in that they can be utilized almost anywhere by merely sprinkling a very light pinch with your desired intention.
Comes in a 1/2 ounce sized packet and this should last you a long time if used correctly.
