 Description 
St. Barbara herb, also known as winter cress, is a biennial, hardy and undemanding wild plant and is named after the patron saint Barbara, who is believed to protect miners and related professions. The species originally comes from Eurasia and today thrives in almost all of Europe due to its robustness. Winter cress can be used raw or steamed as a salad or vegetable and has a blood-purifying effect and is therefore used in natural medicine. The fresh leaves have a spicy, slightly hot taste that is reminiscent of watercress, but less hot.
