Dendrobine (Standard) is a reference standard for research and analysis in studies involving Dendrobine. 1. Dendrobine has a slight but demonstrable analgesic and antipyretic action. 2. Dendrobine produces moderate hyperglycemia, diminishes cardiac activity in large doses, lowers the blood pressure. 3. Dendrobine on the electrical activity and on amino acid-induced depolarizations of primary afferent terminals were tested on the frog isolated spinal cord.
