Saucia cabbage, sorrel ordinary.

Probably many in the childhood tasted this plant. As a child, we called this forest grass "hare cabbage". I don't know why until now. "Hare" - even more or less clear. But why "cabbage"?
Sour ordinary in moderate amounts edible and even useful. Uses it to treat a number of diseases of traditional medicine. Noticeable flowers and peculiar leaves of common acidity decorate the wood very much, especially at the end of may – the beginning of June.
