5 Element Theory is one of the oldest and most comprehensive systems of body assessment in the world. It is an extremely important tool in treating the body as a whole. We will build upon your 5 Element Theory understanding throughout the entire Master Herbology & Advanced Nutrition Program. It is critical that you understand this foundational principle. The way Dr. Hollist teaches the application of 5 Element principles is unlike any that we have ever seen and based on our students experience, we feel that it is the most practical style of use available today.
