"Iridology" is a natural health assessment technique analyzing the iris to evaluate overall well-being. Iridologists use tools like cameras, flashlights, and microscopes to look for tissue changes and pigment patterns in the iris, which are believed to correspond to various organ systems and health conditions. Iridology can detect conditions like hypertension, hyperthyroidism, liver damage, gallbladder issues, inflammation, and weakened immune systems.
