Link to other Hoodoo Oils Recipes and Discussion for discussion of things such as base oils, and methods.

Use approximately 2 ounces of base oil, to 2 tablespoons of actual herb, and then let the oil mixed with herb sit in a cool, dark (and preferably consecrated,) place for 3 or 5 days.  After this, check the oil for scent.  If you like the strength of the scent it is done. 

If the scent is too weak after 3 days, strain out the pieces with cheese cloth, and then add another 2TBSP of your base herbs, and let it sit another 3 days. 

In making the oils, some people chant a spell or rhyme over them while making them, and most people hold the bottle in their hands and push their energy into it with intent.  You can also enchant/charge the herbs before using them to make oils.

Some people prefer to take everything out afterwards, but others leave the herbs in the oil mixture.

If you are using essential oils instead of the herbs, I would suggest some trial and error, and nowhere near the tablespoon... perhaps 5-10 drops per ounce of base oil.  You can check the scent of the oil right away, but still should put the oil to cook for 3 days, to let the mojo work.

PLEASE NOTE:  The above is from Ray Malbrough's "Charms, Spells, and Formulas."  I've noticed that many of the herbs/flowers are in multiple signs, but the rest of the recipes in the book seem to be spot on and I've used some.  This is the only recipes I have for Astrological Oils.

For herbs that *are* in multiple signs of the zodiac, this is most likely because those actual herbs have different properties depending on their use, and can be attributed to those different signs.
