“We can’t talk about our own health without understanding our place in our environment, because in order to fulfill our potential we have to live in the context of our surroundings.”

“We have to know our place in the ecosystem of which we are a part, and this means living 'consciously': being aware of nature and how it affects us and how we, in turn, affect nature.”

The Process


The course was compiled and written in response to seeing a great opportunity for truly preventative medicine. In fourteen lessons you will explore directly with instructor/author Shantree Kacera the unique synthesis of Western and

Eastern Protocols in Constitutional Medicine. The course content is organized in three sections: theory, diagnosis and body systems.

Tongue diagnosis is a vital instrument used in Ayurvedic Medicine both for assessing the current health of a patient and providing a basis for prognosis. It also informs the practitioner about the underlying challenges of the patient's constitution. The tongue gives very accurate information about the state of Prana and blood, progression and regression of disease, degree of heat and cold and the depth or penetration of a pathogenic imbalance. This course is taught by Walter 'Shantree' Kacera bringing to the practitioner a very important and flexible resource for those wishing to integrate tongue diagnosis into their private practice.

Answering the Homework Lessons

This course is divided into seven sections with a total of 14 chapters. Each section has study questions that the student should answer e to assure that they have learned the main points of the chapter. Not all the material in each chapter has equal weight, so what is more significant will be evident from the questions. Not all the answers are found in the course textbook material but may require additional thinking because the course encourages the development of creative intelligence and not just the looking up of answers in a book. If you cannot find the answer see if you can discover an answer to it by your creative thinking based on the fundamental teachings of this course. After completing the questions in detail to the best of your ability please return to us. This course is meant to be thorough and engaging, to really teach the foundation and is not meant to be easy.
