To apply the knowledge of how different drugs are affecting the human body to practice safely and effectively, you need to study the field of pharmacy. It requires the ability to prepare and dispense medications as well as to take care of the patients, and in many cases even business and retailing skills. Familiarity with laws and regulations concerning management of a drugstore are also a must for a pharmacist. Originally, pharmacy denoted treatment of different ailments using natural herbs and chemical substances. Though having significantly evolved since the time of its emergence, pharmacy still relies on the knowledge of pharmacology, medicinal chemistry, and chemical biology. Human anatomy and microbiology fields are essential for pharmacists as well. There are technicians and aides needing similar knowledge that are supporting the work of pharmacists by performing administrative duties and dispensing drugs under the supervision. Clinical pharmacists working in hospitals may be specialized in particular medical disciplines such as toxicology, herbalism, oncology etc.
