Biliary Dysfunction & Onsen | Sulfate Springs to Stimulate the Gallbladder

Published May 6, 2026·1min read

Biliary dysfunction (impaired gallbladder or bile duct function) has a recognised drinking indication for sulfate springs in Japan's Ministry of the Environment guidelines. Sulfate ions stimulate gallbladder contraction and bile flow, improving fat digestion and relieving bile stasis.

Sulfate ions (SO₄²⁻) in sulfate spring water reach the duodenum after drinking, stimulating CCK release and causing gallbladder contraction. This expels bile into the digestive tract, improving fat digestion and relieving congestion in the biliary system. These springs have been used in European spa traditions as "gallbladder springs" for centuries.
