TEXT 2 Read the text and answer the questions: DRUGS Drugs are chemical substances used in medicine in the treatment of disease. These chemical substances can come from many different sources. Drugs are obtained from various parts of plants,such as the roots, leaves, and fruit. Examples of such drugs are digitalis (from the foxglove plant), and antibiotics such as penicillin and streptomycin (from plants called moulds). Drugs can also be obtained from animals;for example, hormones are secretions from the glands of animals. Drugs can be made from chemical substances which are synthesized in the laboratory. Anti-cancer drugs, such as methotrexate and prednisone, are examples of laboratory-synthesized drugs. Some drugs are contained in food substances; these drugs are called vitamins. Drugs are dispensed and stored in an area known as a pharmacy.
