Zoom LIVE Training Classes – experience the enchanting world of Aromatherapy

Special Offer – normally €995.00 now only €595.00 !

At Green Tara College we teach you how to use Aromatherapy essential oils in an in-depth method.  Aromatherapy can be used for many ailments, for deep healing and relaxation. We teach from a spiritual perspective and work with students to develop the ‘extra sensory’ skills of tuning into a client’s energy field. We will teach you to bring to your client the treatment they truly need.

Some of the classes will be a blend of practical and theory via Zoom to experience and learn the application of Aromatherapy.

This was a fantastic learning experience. I have had an interest in essential oils for years. I wanted to learn the theory of essential oils. It has been a wonderful learning experience with a group of very enthusiastic people. Eileen is a wonderful tutor, her passion and love for Essential Oils. Learning about each essential oil, its plant family, their therapeutic uses is just so exciting. Making synergetic blends at class was so much fun and some ‘wow’ moments when you ‘nose’ your new oil blend is so rewarding. The therapeutic impact of the oils is just amazing. I have benefited from blends as have some people who were my case studies. I would highly recommend this course. So much fun as well engaging with others in group.
