While cascarilla is not something you would find among the many supplies of a Wiccan or Occult practitioner, cascarilla is an important ingredient found among the practitioners of Curanderismo, Espiritismo, hoodoo, Palo, Santeria and Vodou as a well known source of protection, tool of invocation, purifications and cleansings.
Cascarillia’s roots can be traced back to West Africa where the practitioners there used what is called efun, sacred white earth. When they were brought over in the slave trade they had to find a substitution which they did in a large tropical shrub. They would finely ground the outer bark which possessed a nearly white color and over time was transitioned out to using crushed egg shells.
Cascarilla is used to ward off negativity no matter the source, used to draw symbols of protection upon doors, window sills, person’s body and seals everything off to immaterial creatures and antagonistic forces, harmless ones as well. When crushed into powder form in can be sprinkled into floor washes when mopping or rubbed over the entire surface of a coconut and starting at the back of the house all the way to the front door rolled around to cover every inch of your dwelling to pick up negativity. It is included in spiritual baths and is also used in Palo to draw Firmas of the spirits when doing spiritual works.
In Vodou it can be used to draw the veves of the Loas being called upon and just like in Palo in which it is used to draw the firmas of the nkisi, washed away with liquid that is poured over it but since Vodou has its own way of making veves it is ever rarely used.
