Like other serpent poisons Crotalus acts primarily upon the cerebro-spinal nerve centers, producing secondarily decom- position of the blood, a destruction of blood fibrine, hemor- rhages, ecchymosis, etc. (see Lachesis). The most essential peculiarity of Crotalus is the similarity of its poisoning to that induced by yellow fever, in the treatment of which we find its chief use.

The chief clinical use of Crotalus is in the treatment of low, malignant fevers, and adynamic conditions in general, especially when characterized by a hcemorrhagic tendency, and putrescence, and whether caused by zymotic or septic poisoning, or by previous low states of the system, blood poisoning predominating. In all such conditions there is also great prostration; low, muttering delirium; vomiting of bile or blood; tongue, dry, brown, cracked, or yellow, brown in center, red edges; urine scanty, dark, almost black, sometimes suppressed, etc. In this class of diseases, in which it may be indicated, and has been frequently used with success, are: malignant scarlet fever, also with epistaxis, dark red, tumid, or gangrenous tonsils; diphtheria; hemorrhagic measles, eruption dark, confluent; malignant remittent fevers of the south, especially the so-called hemorrhagic malarial fevers; low bilious fevers; typhoid.
