In primitive societies sick people had to rely on medicine men and
witch doctors.(Some people still rely on them. ) It was believed that a per-
son was sick because he has been attacked by evil spirits The witch doctor's S1.______
job was to drive away these spirits. S2.______
His technique involved a combination of three methods, first of which S3.______
was religious. He chanted magic words, and used good luck charms which
he thought had power on the evil spirits that supposedly had entered the S4.______
victim's body. Secondly, he deliberately fed the ancient mixtures, and were S5.______
often filthy and disgusting, to make the evil spirits so uncomfortable that
they would glad run away and so enable the patient to get well. The third S6.______
method was to give the patient medicines preparing from certain plants and S7.______
herbs that were similar in shape or texture to the various organs of the
body. From our points of view, this was the only method that had any val- S8.______
ue. Modem scientific study has shown that some of these remedies had real
usefulness in curing sickness, and at least in relieving pain, but not for the S9.______
reasons advanced by the witch doctors. S10.______
