Iridology Education

01/28/2026

The first step in an iris assessment is to evaluate the base color of the iris. The base color determines the color constitution. Eye color is determined by genes that are passed down from the previous three to four generations.

There are three primary color constitutions. They are lymphatic (blue or green), biliary (light brown usually with gold and orange), and hematogenic (darker brown, can be almost black).

We’ve talked about the lymphatic (glue/green) constitution and the hematogenic (brown) constitution, but what about eyes that are not blue/green and eyes that are not really brown?

Where do they fit in?

Irides that have some brown, gold, and maybe even flecks of other pigments AND have some visible fiber when examined with magnification fall into the category of Biliary.

Without magnification these eyes can be tricky to categorize. They can look brown. Clients are often surprised when I pop their iris photos onto the computer monitor to see how uneven and not brown their irides really are.

These irides have a very uneven color, often with heavier, darker pigmentation toward the pupil, and golden highlights toward the outer edge.

It takes a lymphatic parent, and either a hematogenic or biliary ancestor to produce biliary offspring.

Because of this, the biliary person has predispositions to traits of their lymphatic and hematogenic ancestors. That means we can see over-acid traits like asthma, allergies, arthritis along with hematogenic traits of challenges with blood, liver, and digestion.

There are yet iridologists who are still practicing and teaching outdated concepts. Some of the worst concepts circle around the biliary constitution.

There was a time that we believed all eyes should be blue or brown, and that these mixed irides were an indication of current toxicity levels. We recommended cleanses, fasts, special diets - all in an effort to cleanse out toxins and turn the irides blue. We have known for 50 years that this is inaccurate.

Eye color does not guarantee these types of issues, just warns us of the body’s potential chemistry.

Eye color is only one aspect of a constitution.

Every detail we observe gives us information about why a person has symptoms, but none of them give us disease names. We never use iridology diagnose.

If you want to learn more about iridology leave a comment or send me a DM.

Iridology Case Study Disclaimer - nothing in this article is meant to diagnose or prescribe. As an iridologist, herbalist, and holistic nutritionist I assess and recommend. I do not name or treat diseases. I educate my clients to regain control of their health. All iridology predispositions noted are not guarantees of problems. They are simply warning flags of epigenetic tendencies.

The Case
Female, age 70 yrs 5’2”, 152 lbs

She reported historically being very healthy, bright, alert, active. I noted her excellent skin tone and lovely smile, although she was quite subdued in demeanor.

Primary reasons for coming to see me:

1) over the past 5 months her stomach gurgles whenever she eats, can only eat small amounts, frequently upset stomach, burping and belching; can have feeling of tightness across upper abdomen just below ribs

2) She was previously very active, biking, gardening, hiking, playing with grandkids but now has no energy and feels depressed

3) Started waking with headaches in the middle of the night, especially in her left eye, drinking caffeinated tea relieves the headache.

She cannot recall anything out of the ordinary in the months leading up to the onset of symptoms. Her diet is largely organic, homegrown, home-preserved, and very clean. She had been to her doctor who ran basic blood tests and prescribed a probiotic supplement.

Lab results:
eGFR 51 ALT 195
Hemoglobin 148
Hematocrit .45
Vit B12 1047
TSH 6.66
H pylori negative

Iris analysis: Inherent indicators

The indicators noted below are inherent and do not indicate toxicity, nor do they give us disease names. They indicate epigenetic potentials. Biliary constitution (light brown eye with visible fiber): predisposed to liver and digestive tendencies. Refer to the arrows on the images.

Red arrow: collarette, largely obscured by brown pigment suggests predisposition to inherent liver imbalance that can affect intestinal function

Yellow arrow: gray pupillary border suggests an inherent predisposition to inefficient functioning of stomach lining and protein digestion

Blue arrow: contraction furrows suggest the tendency to internalize stress and hold onto it, functioning largely in sympathetic nervous system

Iris indicators are genetic and do not disappear when health is brought back into balance. Sclera markers may be genetic or earned. As such, earned sclera markers may disappear, but they often take years of dedicated effort.

Indicators that may have built over time

Purple arrow: corneal arcus: suggests longstanding liver enzyme imbalance affecting carbohydrate metabolism, potentially leading to elevated cholesterol or insulin resistance

White arrow: increased risk of fermentation, often an indicator of dysbiosis. Since she had already seen her doctor, her doctor had only recommended using a prescription probiotic, but it had been ineffective on its own. Like the doctor, I wondered if something had created a sudden imbalance in her gut biome. Her sclera indicated this could be the case.

I encouraged her to continue using the probiotic her doctor had prescribed and I suggested she try taking:

Aloe Vera Juice: 1 ounce two time per day, historically used to aid digestion and support the gi tract

Broad spectrum Digestive Enzyme formula that includes herbs that have traditionally been used to support the liver: 1 capsule per meal

Kefir: ¼ cup per day

Follow-up 6 weeks later

In our follow-up session, this client reported a dramatic turning point on day 8. Her energy was back, the depression was gone, the abdominal pain was gone, as were the headaches. Her stomach only grumbles if she overeats.

Many RNs, NDs, MDs, and RMTs have heard of iridology. Unfortunately, what they’ve mostly heard is misinformation that makes it sound like a charlatan’s game.

And honestly, there’s a reason for that.

As medical understanding has evolved over centuries, practices once considered standard—bloodletting, trepanation, administering mercury, arsenic, even radium—were eventually proven inaccurate, ineffective, or unsafe and replaced with better approaches.

Iridology, in its modern form, emerged about 200 years ago. Some early theories were, in fact, questionable. But over time—and through extensive clinical use—more accurate, functional information has been uncovered. Sadly, some practitioners never updated their understanding and continue to teach outdated concepts that are simply incorrect.

In the past 60+ years, iridology has evolved significantly—much like modern medicine itself. Today, when practiced correctly, it is a refined assessment tool that can save you time and help you quickly focus on what matters most for your clients.

Ask any longtime practitioner what separates those who succeed from those who do not, and you’ll hear one word - confidence.

We’re not talking about arrogance here. We’re talking about having the textbook/classroom learning AND the skill to apply it well.

Sadly, most holistic health courses only teach the head knowledge. They lack the application side because that takes time and is developed through mentoring ~ close, insightful, feedback-rich mentoring.

With the Dynamic Iridology Assessment System for Health Professionals course, you get both - classroom learning and long term mentoring.

Because that’s how confidence is built.

Who do you know that has blue eyes?

What blue eyes tell you about your client's health potentials.

A quick look at blue eyes - the lymphatic constitution.

01/09/2026

Standing next to my daughter in this photo, your can see how different our eyes are. Mine are hazelish. Hers are blue. But did you know that our eyes can reveal so much more than just color….even subtle clues about our health tendencies and potential risks???

While genetics explains the color, iridology helps us understand what those variations, and the patterns within the iris, can tell us about the body.

The irides can offer insight into inherited strengths, areas that may need more support, and even early indicators of stress long before symptoms show up.

It’s one of the reasons I love sharing iridology with health professionals: it gives them a way to see their clients more holistically and proactively.

Because when you understand what the eyes are showing, you can guide care in a completely different way.

01/07/2026

RNs and NDs have this in common: Both groups are making 1 big mistake.

They are using lab tests as their FIRST level of testing.

Here’s where that’s an issue:

You run batteries of expensive tests based on symptoms.
Those tests take time, and in some cases waste money, that would be better spent on treatment options.

What if you could know exactly where to start by looking at your patients' eyes for genetic tendencies and asking questions that tie their symptoms to their inherent predispositions?

You could:
– > start treatment right away
--> run fewer tests to confirm your findings
--> save your time
--> save your clients' money.

If you are curious, and want to learn more about a non-invasive way to assess your patients, let me share my 45 years of holistic clinical experience with you.

I’m hosting a webclass to share more about clinical iridology.

Einstein & me - we’re buddies!

I don’t claim to be a genius - but I do like the way he thinks!

Like when he said "The measure of intelligence is the ability to change"?

So, I’m curious - do you agree with Einstein and me?

You’ve probably seen a lot of change in the medical and holistic health world over the last few years. The changes I’ve seen in the past 45 years as I’ve studied iridology, nutrition, and herbology have been pretty mind boggling.

Much of what we ‘knew' about iridology and nutrition in the early 1980’s has been disproved.

If you've seen/heard people say…

you need a cleanse
you’re toxic
you have parasites
your lymphatic system is congested
you can change eye color from brown or hazel to blue
we can diagnose from what we see in your eyes
…you’ve heard info that is not current or valid.

Iridology has come a long way and every teacher and practitioner has not kept up-to-date.

Teaching and mentoring health professionals in the current art, science, and application of iridology is where my heart is. If you’re curious about iridology, drop a comment below or send me a DM - let’s talk.

Do you remember Dr McCoy on Star Trek and his handy dandy tricorder?

It could tell him exactly what was wrong in real time.

We used to think iridology could do the same -
that each mark meant one problem -
but that was based on theories that have never been proved.

What it does instead is help us to understand the relationships between organs and symptoms in minutes...just like the tricorder.

That gives us a depth of understanding that can guide the tests we run and the recommendations/programs we make.

Since we don't have Tricorders yet, iridology is a great second best for enhancing the depth and speed of assessing clients.

And that's exactly why I love teaching constitutional iridology to health professionals.

Maybe you were napping and didn’t see it - or maybe you meant to follow through but forgot.

This is the last chance you’ll have to register for the final iridology webclass of 2025.

Here’s what we’ll be talking about -
Assessing the potential efficiency of the stomach.

Put in other words - digestive system indicators in the irides.

You will walk away with new knowledge you can use with your next client.

So join me tonight - Thursday, December 18, 2025

This guy didn’t send me feet pics, thank goodness. But in the email he sent me, he included photos of his

Eyes.

(and believe it or not, that’s not all that uncommon!)

Don’t worry - he wasn’t looking for a date. He wanted me to do an iris analysis from photos with no other information. This used to be pretty common. People would send in their photos and we would ‘diagnose’ health issues from them.

And because there are still people practising and teaching based on those disproved theories, the general public expects a ‘diagnosis’ from their photos.

→ Back to the guy and his photos.

He said he’d recently quit smoking and wanted me to tell him, from his photos, if he should do a cleanse. I couldn’t answer that honestly, as I had no other information about him - medications, surgeries, health history, current symptoms - only photos.

And while his iris photos provide a lot of base information about his health predispositions, they don’t reveal transient information ~ and as a health professional it is irresponsible to give client specific recommendations without his health history information.

It is reckless, potentially dangerous, and definitely unprofessional to give client-specific recommendations from photos only without background information.

So, for sure, don’t send me your feet pics. Or even pics of your eyes!
