"she carried the powers of a Traiteur, a treater;"

Traiteur is the French Acadiana term for a faith healer.

The primary method of treatment involves laying hands on the person in need of healing. The healing is a combination of Catholic prayer and medicine. Many, like Grandmere Catherine, refuse to accept offers of payment for their services because they see their gifts as being from God. Very few traiteurs exist in the modern world. According to tradition, Catherine's daughter Gabrielle could not have possessed traiteur powers because the rituals are passed down only to the opposite gender.
