Electro-ionic medication or medical ionization, properly called iontophoresis, was much in vogue thirty years ago. Then its use subsided until Warwick reported the successful results he obtained by using that method. Medical ionization is the introduction of ions into the skin or mucous membrane by means of the galvanic current.
APPARATUS AND ACTION
The galvanic current can be produced by several methods, namely: 1. By batteries which give a pure constant current. This set-up has been made for years by different manufacturers. An inexpensive set has recently been described by Macfarlan.1 2. By the galvanic wall plate in which the power line is direct current. 3. By the motor generator.
The report on tests of three apparatus by the Westinghouse laboratory is as follows:
1. Wappler Wall Plate.—This device operates from the direct current supply, and the output, therefore, takes on the character of the
