For the second year in a row, when visiting Abkhazia, we come to this hydrogen sulfide source. I am skeptical about various folk remedies for self-medication, but in this case I was pleasantly surprised. While walking and eating blackberries, they were scratched and after bathing in this source, there was no trace of scratches, and with daily bathing for 10 days of vacation, the skin became soft and all sores disappeared. So I heartily recommend it.
