Best Sulfate Spring Hot Springs Ranking
101 hot springs
Sulfate springs contain sodium, calcium, or magnesium sulfates. Long known as 'the wound bath,' they have traditionally been believed to help with cuts, bruises, and chronic skin conditions.
Sulfate springs are said to help lower blood pressure and protect blood vessels, potentially aiding arteriosclerosis and hypertension. They also offer strong moisturizing effects, making them suitable for dry skin.
