Clinical profile

Baths and inhalations with natural sulphide water. There are small RCTs in hand osteoarthritis, rheumatoid arthritis and chronic rhinosinusitis and a meta-analysis on upper airway diseases; Cochrane on rheumatoid arthritis considers the data still insufficient.

Every statement links to a publication in the list below. This is a snapshot of published research, not a final assessment of the method: international practice and integrated protocols often run ahead of official publications. Draft based on published research; requires review by a physician. Revision: 2026-10-17.

Where studies show an effect

  • Hand osteoarthritis: reduced pain and improved function in a double-blind RCT. [1]
  • Rheumatoid arthritis: sulphur baths improved clinical measures for up to 3 months. [2]
  • Chronic rhinosinusitis and other upper airway diseases: inhalations of sulphur water improve mucociliary clearance and nasal resistance. [3, 4]
  • Varicose veins: balneokinesis in sulphur water in addition to compression improved symptoms and quality of life. [5]

Open questions and study limitations

  • Rheumatoid arthritis: Cochrane considers the data on balneotherapy still insufficient for conclusions. [7]
  • In routine practice, the short-term reduction in pain in osteoarthritis falls below the threshold of clinical significance. [6]

Safety

  • Mild adverse events were recorded in 19 of 370 patients during procedures with sulphur water. [4]
Contraindications. Contraindications are determined by the physician according to the equipment or drug instructions; they are not given in study abstracts.

Evidence base

Small RCTs and a meta-analysis on the upper airways; in arthritis the evidence is insufficient.

Publications were found in PubMed; titles and journals are given verbatim, conclusions are a brief summary of the abstracts under the conditions of the specific studies. The level shows the volume of published data, not the value of the method: A — Plenty of data: consistent systematic reviews and meta-analyses of RCTs; B — Some data: reviews or several RCTs, results are heterogeneous; C — Little data: single RCTs or controlled studies; D — Scarce data: mainly reviews, observational and experimental studies. The passport is updated as new work is published and with regard to international practice.
