Henriette's herbal is one of the oldest and largest herbal medicine sites on the net. It's been online since 1995, and is run by Henriette Kress, a herbalist in Helsinki, Finland.
Plant Healer Magazine: Very relevant to the practitioner.
The site runs on a Hot Drupal server. It's like greased lightning, compared to the old VPS setup. If you run a slow drupal site, consider switching!
