Cascarilla is a unique ritual substance that has been used for a very long time in different cultures because of its amazing protective and cleansing properties.
 
In Santeria, cascarilla is a well-known and respected source of protection. Its practitioners use it to create protective barriers around themselves or their homes, to purify themselves from negative energies, or to honor their respected deities in ceremonies. Cascarilla is made from ground-up eggshells that have been cleaned and sometimes mixed with other ingredients.
