List of Herbalists to Learn From

This is not a list of herbalists to acquire services from (even though some may offer that).  This is a list of herbalists who have gone far in their studies and there is much we can learn from them.  We use the term herbalist by convention but it’s not the best fitting term as many forms of healing and wisdom do not require herbs and herbs are only one part of the tool kit of a healer.

Also consider visiting our notable healers section of the Ecoja forums.

This list is in alphabetical order by last name:
