Old time conjure spells often instruct that sachet powders be used on the body, particularly around the chest area. Perfumes are also a common device, instructed for use in many old spells and curio catalogues. These were common products at the time and were used as part of a person's daily toilette, to keep a person fresh and sweet-smelling.
However, these days, how many people use talcs and perfumes every day? These spell instructions are clearly the products of a time when deodorant and moisturizers weren't the norms, like now, and body powders and colognes were more common instead. Current belief is that perfumes are a nuisance, and the only person I know that uses body powder on a daily basis for health and beauty, is over 90 years old.
The body powder of today is underarm deodorant. Curiously, no one seems to sell these with hoodoo scents that I have seen. Lately, I have learned how to make an excellent deodorant at home -- in fact I got rid of my expensive premade deodorant because the homemade stuff worked so much better. It's not an antiperspirant and it can sometimes leave a powdery mark on dark colored clothes, but if you can deal with that you can not only make your own deodorant, but you can also fix it with whatever hoodoo folk magic formulations you want!
There's a few different ways I have found to go about this, so here is one of several varieties of the homemade hoodoo deodorant. This one uses anointing oil.
3 parts* anointing oil of your choice
2 parts cornstarch
4 parts baking soda
Combine the dry ingredients thoroughly, then add the oil and combine well to make a paste.
*I find a creamy texture is the easiest for me to apply and use, but if you'd like a thicker or thinner texture you can add or subtract oil as desired. This is intended to be applied with your fingers, but I know of people who've made firmer-textured versions that could be pressed into empty deodorant containers and applied the normal way.
Other variations include the deodorant made with powder and deodorant made with colognes like Hoyt's or Florida Water. I will post recipes for these varieties at a later time.
