Historical Modalities I: Iridology Online
Holistic Medicine

Can we tell the constitution or health issues from the iris of the eye? This course leads students through the theories of iridology, from historical to modern day, including the modern controversies and conflicting information from the fields of identification. Learn the basis of this modality and decide for yourself.

ACHS President Dorene Petersen shares this about ACHS's IIPA-Sanctioned Certificate in Iridology program:

IPA’s sanctioning of our Certificate program gives ACHS students even more confidence in their training and professional goals, and provides a strong connection to an outside organization with almost 30 years’ experience in the field. IIPA maintains the utmost integrity, professionalism, and certification and standards, and provides a wonderful opportunity for iridology professionals to learn from, and exchange information worldwide.”

Upon successful completion of this course, each student will be able to:

  • Identify and explain constitutional classifications.
  • Describe and explain the structure and function of the eye.
  • Explain the healing crisis and Hering's Law.
