An intermediate plate with a plurality of apertures is positioned between the upper and lower ends forming upper and lower chambers. A positioning ball has a lower portion within the upper chamber and an upper portion above the upper chamber. A hole is in the lower portion of the positioning ball. A cartridge supporting a quantity of therapeutic liquid is removably received in the lower chamber of the shower head. The therapeutic liquid is dispensed from the cartridge into a path of travel of shower water flowing through the shower head.
