Abstract

The present invention provides a new, practical, and inexpensive approach to labial herpes heat therapy. Heat is produced by the chemical reaction of elements contained in an inexpensive, portable and disposable air-activated chemical warming device that is small enough to be applied to an affected lip area. For example, a person can store the warming device at home and work, or simply carry a warmer in a purse or wallet. The warming devices can have a long shelf life.

Claims

1. ) An air-activated chemical warming device for the treatment of cold sores, comprising:

a. a pouch comprising iron powder, salt, water, activated charcoal, and an absorbent material in a permeable covering, wherein oxygen reacts with the iron powder to release heat when the pouch is exposed to air, and wherein the relative proportions of the constituents of the pouch provide an output temperature within the treatment range for cold sores; and

b. a heat application surface on the pouch that is amenable for effective therapeutic contact to the skin of a patient.

2. ) The device of claim 1, further comprising an air-tight protective packaging that is substantially impermeable to oxygen and water and configured to contain the pouch such that the iron is not exposed to excess oxygen while the pouch is in the protective packaging.

3. ) The device of claim 1, further comprising a surface lubricant, oil, or moisturizer on the heat application surface to improve the skin contact properties of the surface.

4. ) The device of claim 1, wherein the quantities of iron powder, salt, water, active charcoal, and absorbent material are selected to heat the pouch to a temperature in the range of 50°

C. to 52°

C.

5. ) A method for the treatment of cold sores, comprising:

a. providing a pouch as in claim 1,

b. exposing the pouch to air wherein oxygen in the air reacts with the iron powder to release heat, and

c. contacting the heat application surface to an affected area of an affected tissue site.

6. ) The method of claim 5, wherein the contacting occurs when the pouch has reached a temperature in the range of 50°

C. to 52°

C.

7. ) The method of claim 5, wherein the contacting occurs during the prodromal phase of the cold sore process.

8. ) The method of claim 5, further comprising storing the pouch in an air-tight protective package prior to exposing the pouch to air.
