Pulvermacher's chain, also known as Pulvermacher's catholicon or Pulvermacher's electro-galvanic chain, is a type of medical device that was developed in the 19th century. It consists of a series of connected galvanic cells made from galvanic metals—typically zinc and copper—arranged in a chain. The purpose of this device was to deliver low-level electrical currents to the body for therapeutic purposes.
