Repro looks good, but I'm not sure how it would be used.
From a medical reference: "Saturated solutions of potassium iodide can be an emergency treatment for hyperthyroidism, as high amounts of iodide temporarily suppress secretion of thyroxine from the thyroid gland. The dose typically begins with a loading dose, then 5 drops or 250 mg iodine as iodide, three times per day.
Iodide solutions made from a few drops of potassium iodide have also been used as expectorants to increase the water content of respiratory secretions and encourage effective coughing, although this has passed from common use.
Potassium iodide has been used for symptomatic treatment of erythema nodosum patients for persistent lesions whose cause remains unknown. It has been used in cases of erythema nodosum associated with Crohn's disease.
Today it is used to block radiation when doing radiation therapy, or when radiation exposure is suspected, as it blocks radioactive iodine from entering the system. But in 1942...?
