At Core College, students are introduced to a tradition rooted in vitalism, which recognises health as the body's natural state and disease as a departure from that inherent balance.

The College's approach is founded on a deep understanding of plants, people and the natural world, with equal emphasis on knowledge, practical application and lifelong learning.

Students are taught to work with the body’s own powerful healing ability.

The college is located in the former Presentation Convent and gardens, on Kilkenny Street, Castlecomer. The building provides the perfect character, history and space for teaching herbal subjects.

Carefully restored, the campus is now home to certified organic medicinal herb gardens, a public herbal medicine clinic, a herbal dispensary, and a dedicated herb-processing facility where plants grown on site are prepared for use.

Located just 15 minutes from Kilkenny City, the college is also within walking distance of Castlecomer Discovery Park, hotels and local restaurants.

Antonella Di Cillo, graduate of the Herbal Medicine Programme, speaking about her experience at Core College.

“Having a working medicinal garden and being able to actually connect with the plants is something I had not found in other schools. You cannot teach that connection. You have to live it.”
