The Anti-inflammatory Effects of Harkány Medicinal Water

Study Purpose

The study aims to provide evidence on the effectiveness of Harkány medicinal water in psoriatic and rheumatoid arthritis patients using subjective and objective methods. It is a cross-over study, so first half of patients will receive medicinal water, the other half will receive tap water treatment, and after 6 months treatments will be repeated, but patients will receive the other type of water.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Several studies have shown that medicinal waters are highly effective in the treatment of many diseases. Existing clinical trials were unable to provide scientific evidence by using the highest international standards to justify the efficiency of thermal waters. Harkány medicinal water has been used for rheumatic, skin and locomotor diseases for more than 100 years. Its beneficial effects are indisputable. However, to introduce these effects, internationally high-level scientific methods and investigations are needed. Psoriasis is among the most common dermatological diseases worldwide. Its significance is emphasized by adverse effects on quality of life, caused by chronic pain, physical and psychical disability due to psoriatic plaques. Former studies revealed an increased risk of inflammatory bowel disease, cardiovascular disease and certain types of cancer. Moreover, excessive oxidative stress can be responsible for the onset of psoriasis complications. Rheumatoid arthritis (RA) is an autoimmune disease responsible for significant morbidity, characterized by articular inflammation. Oxidative stress is a key marker for determining pathophysiology of patients with RA. The pathophysiological link between these conditions is the presence of excessive oxidative stress. Subjective methods will include questionnaires, objective markers of disease severity will include the measurement of biomarkers from blood samples.
