Are you meaning practitioners in medicine? Generally speaking the only recognised role was as midwife. unofficially many women, and some men did deal in treating conditions with natural remedies such as with the use of Herbs and healing plants. They were usually known as ‘wise women’. It was a very fine line to walk though because they could find themselves charged with witchcraft if their activities moved beyond the use of natural plants and herbs.

Depending on the order, some convents had facilities for nursing and, often undercthe oversight of a religious brother from a neighbouring monaster, nuns provided basic care not only for one another but local women who presented themselves at their gates, subject to the Mother Superiors permission.
