Treatment with an Arab Doctor

Dr. Nader Butto is well-known as a cardiologist and healer using energetic cleansing methods. I underwent energetic cleansing (which is treatment through guided imagery, healing, and chakra opening). At the end of the treatment, I learned that Dr. Nader and his brother Youssef are Arab Muslims. I felt very uncomfortable about this. Is it forbidden to go to Arab doctors or therapists? If I already went, should I recite a prayer or do something to nullify this energy? I would appreciate an urgent response.
