She draws on her patients' faith, and uses herbs, fruits, eggs, and oils that her patient has easy access to. The patient's family and friends are also used as healing resources. The sick person may have a physical illness to be cured by herbs or other traditional procedures. The physical illness may, however, be caused or aggravated by the supernatural. This requires special treatment by the curandera.
Faith then becomes an important part of recovery.
There are three levels that an intern of a curandera must learn. Each level is similar but takes a different talent and training. The first level is the material level. On this level many daily illnesses are treated. Along with curable diseases, discomforts caused by negative forces in a patient's life, such as anger and fear, are dealt with using rituals and herbs to restore a patient's emotional and physical balance.
