4 The American Red Cross says all homes should have at least three substances to deal with poisoning. One, syrup of ipecac(吐根糖浆),is a fluid that helps the body expel material from the stomach. Another, activated charcoal (活性炭), lessens the er of poisons. The other material, epsom salts(泻盐), helps to speed the release of body wastes. All three should be used only on the advice of a medical expert.
5 The Red Cross says expulsion (清除) of material from the stomach—vomiting (呕吐)— sometimes may be started if medical advice is delayed. But it says vomiting should be used only when it is known the victim took too much of what is called a general poison, such as a medicine. The experts say never cause vomiting if the victim was poisoned by a petroleum product or by a substance that was a strong acid or a strong alkali(碱). These victims should be taken to a medical center as soon as possible.
