In 1857 Dr. J. Francis Churchill introduced the hypophosphites into medicine, proposing it as cure to for pulmonary tuberculosis (phthisis). He envisioned that the cause of the disease was insufficient oxygen in the tissue and that the use of hypophosphites would increase the amount of oxygen. Therefore, hypophosphites were widely used in pharmaceutical tonics etc, but later investigations proved it to be wrong. Today it is used as, for example, a food additive and in electroless nickel plating. Wintzell & Fried did not contributed to Dr. Churchill’s method, but we are contributing to the EU regulations by REACH registering sodium hypophosphite.
