Oils are used these days in Hoodoo for their expediency. They are carriers of magical intent. Each drop a liquid mojo bag. The oils you come across in Hoodoo are referred to as condition oils, this is because they are used to treat certain specific conditions. A small quantity of oil goes an amazingly long way. Oils can be used to dress candles, dress objects ( shoes, wallets), for annointing, for altar work, to make up a condition powder etc, etc. Oils are probably the most versatile medium for Hoodoo. And something magical that shifts your condition into better balance. In Hoodoo, where secrecy is preferred, oils work discretely. They hide in plain sight.
