Pilonidal cyst is a kind of a skin abscess that usually occurs along the tailbone or coccyx. The term pilonidal has its roots in the Latin words pilus which means hair and nidus which means nest.

Since castor oil can draw out impurities easily so it also has the healing power to cure a pilonidal cyst because it draws out the impurities from it such as hair and debris.
