In the mountain of Vallehermoso, La Gomera, you can find Los Chorros de Epina, a spring water fountain with seven heather wood spouts.
According to popular tradition, its water has healing properties. The wealthy families of Vallehermoso used to send their maids to Epina (spending a day's walk) to fetch water from this spring, and to make sure that it was really the water of Los Chorros de Epina, they had to bring, in addition, an aderno leaf, a tree that only grew near this magical spring.
