Scorpionism is a major health problem in under developed countries. No specific antiserum or any other antidote is available for the treatment of a patient suffering from scorpion sting and hence prepare of a potent antiserum against scorpion venom is an utmost requirement. This book describes the toxicological effects of Asian Black scorpion Heterometrus fastigiousus and the method to prepare species specific antiscorpion venom. It is hoped that results emerged will be useful in understanding the toxicological behaviour of scorpion venom and simultaneously antivenom raised will find a clinical application in neutralizing the toxic effects of scorpion venom.
