Speaker: Jill Stansbury. This presentation reviews cellular biochemistry and botanical agents which affect cyclic AMP (cAMP).  In new research, cyclic AMP appears to transmit extracellular signals to the cellular membrane and induce enzymatic, hormonal, metabolic and nuclear responses within the cell.  The details of this messenger system are described in the talk along with botanical agents that promote its action (including Coleus, Bupleurum, Tanacetum, Glycyrrhiza, Coptis and many more).
