The use of chlorine gas to cure the common cold was suggested by observations that men who worked in chlorine plants to manufacture the noxious gas during the war were remarkably free of colds and flu. The same was true of soldiers on the front lines exposed to the pungent, biting fumes of chlorine, compared with those in the rear. A hundred years earlier, physicians had noted that people who worked and lived in the vicinity of bleaching establishments had fewer respiratory infections than others.

Chlorine was thought to act as a kind of thorn-in-the-flesh therapy. Vedder (dubbed "the chemical warrior" by Time magazine) proposed that "the irritant action of chlorine stimulates the flow of secretion and cleanses the mucous surfaces," resulting in "productive coughing and blowing of the nose." Through its oxidizing action, the gas was also thought to rid the body of toxins and fuel the activity of white blood cells useful in the attack against offending microbes.

Practically overnight, chlorine therapy became a popular treatment for victims of colds, bronchitis, and whooping cough... For the general public, there was Chlorine Respirine, 50 treatments for $0.50 in a handy collapsible tube, each dose purported to "knock a cold in three hours."

A child's life is a fight! Danger Days are always ahead. Danger Days — the days when little lives hang in the balance — may come next year, next month, or perhaps — tomorrow. Your children must meet these Danger Days. Are they ready? Will they win?

The application is simplicity itself. You merely apply the ointment to the part you wish reduced, then literally, "wash the fat away" without injury to the most delicate skin.

“Previous cure has ben hampered by the inability to get directly at the germs in these darkened passages, but in the new invention the curative rays are played directly onto the germs, being transmitted through a smal rod of the marvelous substance known as fused quartz.

“Fused quartz transmits ultra violent or invisible light without loss, whereas ordinary window glass shuts out ultra violent light which is the curative agent in sunshine.

“In the Curay Light aplicator,” Boerrsteler continued, “we have produced a source of radient energy closely approximating concentrated sunlight in the upper altitude, with an equivalent ultra violent content. Though it is a potent germ killer, it is harmless to the cels of the body.
