IcyHot

  IcyHot is a topical analgesic heat rub meant for relieving pains such as arthritis, backache, muscle strains, muscle sprains, bruises, and cramps. IcyHot is known for its dual action pain relief, claiming it is "Icy to dull the pain, and hot to relax it away".^[1] It comes in cream, a balm, a Chill Stick, and a 8cm x 12 cm patches. Recently, IcyHot has come out with sleeves, knee braces, and foam pads. Although IcyHot does make its user feel heat and cold, IcyHot does not actually heat or chill the area to which it is applied. Instead, IcyHot stimulates nerve receptors, causing the user to first feel cool, and then feel heat. ^[2]

Background

George Foster of the George Foster company in Illinois developed the formula for Icy Hot, and sold it until 1931. In 1931 Jim Gibson bought the George Foster Company and it's numerous products, and ran the company until about 1965. At that time an Indianapolis investor purchased the J.W. Gibson company and it's products. At that time the sales of Icy Hot were less than $5,000 annually. The J.W. Gibson company was then owned by Bryan Auer, and he began marketing the product by running small mail order ads in national and regional publications. The product grew and eventually was picked up by the first drug store chain, based in Indianapolis, called Haag's Drugs. From that, by 1972, the product saw wide spread national distribution. The product's sales grew to approx. $10 million dollars and then in the late 1970's was sold to G. D. Searle (maker of Metamucil) in Chicago. They later sold the product to Richardson Vicks the maker of Vick's vapo rub, and then they were acquired by Proctor and Gamble. Proctor and Gamble then disposed of the brand to Chattem Pharmaceutical and in the 1990's and Chattem has grown the brand to over $50 million and as of 2006 was the number one external analgesic in the United States.
