Cosmo-Light (chromotherapy)

From Kook Science

The Cosmo-Light (later rebranded as Color-Therm) is a device, originally manufactured and sold by Fred Gerkey, a Kansan chiropractic, consisting of a wooden box holding "tubes for producing colored lights similar to the so-called neon lights, together with the electrical connections needed to operate them," which was marketed as an instrument for chromotherapeutic use.[1] According to Gerkey's advertising materials, the device would be used to expose patients to light of a curative frequency, claiming such exposures would be effective in the treatment of afflictions stemming from the "liver, eyes, female trouble, asthma, nervousness and sinus trouble."[2]
