[Effect and effectiveness of iodine brine baths in a spa].

On the occasion of closing the research department of the Paracelsus Institute in the iodine salt spa, Bad Hall, the results of more than 30 years' research work in this institute are summarized. This work concerned the therapeutic effects of iodine on circulatory illnesses, especially hypertension, bronchitis and degenerative eye diseases. Controlled studies in patients showed significant cure effects of the iodine springs. Other studies demonstrated an influence of iodine on peripheral blood vessels, blood viscosity, connective tissue and vision and demonstrated the scavenger function of iodine, too. The different therapeutic forms of iodine administration (baths, sprays, iontophoresis, drinking cures) are described and the potential side effects of a cure in an iodine spa, notably temporary hypothyroidism, are mentioned.
