Cautions by tradition (1)
  • Kallawaya healing in Bolivia: Do not pick along busy roads or on sprayed land.

Preparation

Young leaves raw in a salad or cooked as a vegetable.

Use in traditions

In Bolivia the plant is called khanapaco, 'morning light', because its flowers open in the morning. According to Bastien it was one of the few plants that all Kallawaya healers called 'cold'. They gave it for liver complaints and for anger, which in the Andes is linked to an excess of bile, and laid the crushed leaves on wounds. The leaves were also eaten as a salad.
