Patented in 1918, the Prostate Warmer, Thermalaids, claimed to cure prostatic trouble, frequent urination, diminished sexual strength, backache, foot & leg pains, nervousness, blues, worry & depression, constipation and piles, and many more.
The appliance is inserted up the rectum next to the prostate. Light bulbs with different wattage are used to moderate the heat by limiting the current. The Thermalaids box states, “It represents a prompt and effective method for using natural means in the assistance of nature. It leaves no evil effects.”
