According to legend, she acquired her wisdom after having eaten some Vaccinium vitis-idaea which had been touched by a white snake, who had passed her path one day in the woods when she was a child.
Anna was considered to be a clairvoyant and to have the ability to heal the sick, and she received clients nationwide who consulted her in both these capacities.
Anna adjusted her fee according to what the clients could afford to pay, which meant that she occasionally gave free help.
In her capacity as a natural healer, she used herbal medicine: her daughter Kristina participated as her assistant in this field.
In 1847, Anna was convicted to fines or seven days for superstition after having taught the maid Johanna Jonsdotter to put a spell on her fiancé Johannes Jonsson.
