I seem to be seeing an increasingly large number of patients who react
to exercise or the cold weather with intense itching of exposed areas
or with a rash and hives which can last anywhere from a few minutes to
several hours. This type of reaction is thought to be caused by the
chemical histamine. I have recently had complete success with two
patients, both experiencing exercise induced itching. The regimen I
gave them included: Vitamin C with bioflavonoids, Quercetin, and an
herbal tincture combining Nettles and Eyebright. Now the real job is
looking for the cause. Certain environmental exposures or food
intolerances may have pushed these patients to a heightened allergic
response.
