Those 'other colors' in an iris add depth and valuable insight into your client's health predispositions.

Let's take a deeper dive by looks at three of the many constitutional sub-types that give us even more insight into epigenetic predispositions.

This is the kind of insight that really directs client appointments to help you find the roots of health problems faster.

Very few eyes are an absolutely pure color. Most have other washes or pigments in them in patches and clouds. Those washes and clouds create the Constitutional subtypes.

The overacid sub-type is seen only in the lymphatic constitution. This white clouding often hugs the collarette. The white is very white, like printer paper, not whitish. As the name implies this subtype is predisposed to having too much acid systemically. We’re not talking about stomach acid here.

The uric acid diathesis has yellow or gray clouding. In my practice I’ve seen this mostly as yellow clouding. As the name implies this suggests a predisposition to holding onto an excess of uric acid. Think of this as inefficient excretion of uric acid which can allow the uric acid to accumulate.

Ferrum Chromatose is primarily seen in biliary and hematogenic irides.This sub-type suggests an inherent potential for iron assimilation imbalances and leads us to ask questions about the client’s history of anemia or excess iron in their blood.

Notice that through all of this, I’ve never said we ‘diagnose’ with any of these constitutional subtypes. - and that’s because we don’t.

We use iridology to understand symptoms, and guide the questions we ask. It does not let us name diseases, but it shows us where the inherent, epigenetic weak links are.

Now that we’ve introduced the three primary color constitutions, it’s time to move on to the four primary structural constitutions.

Just like the color constitutions, the structural constitutions are determined by genes that are passed down from the previous three to four generations.

The structural constitutions give us insights into health and emotional/personality predispositions.

Here’s a quick synopsis of these constitutions.

Neurogenic
The neurogenic type will have fairly evenly placed fibers that radiate outwards. There will be few, if any, fiber separations. These people like to be in control of life, have all their ducks lined up in a row, and as long as they are, all is well.

They tend not to like surprises or having wrenches thrown into their plans.
They can be structurally strong, but may take it for granted and thus end up weakening how their bodies work.

Anxiety Tetanic
Concentric arcs in the iris are a primary indicator of the anxiety tetanic type.
These people like to be busy and productive. They like lists and they internalize their stress.

Polyglandular
This type of eye that looks like it has flower petals in it.

They tend toward hormonal imbalances - think blood sugars, reproductive, and endocrine in general. They also tend to be emotive and creative.

Connective Tissue
As the name implies, the connective tissue is usually the weak link.

These people are more prone to strains, sprains, breaks, premature collagen breakdown - they get wrinkly at younger ages - and slow healing of wounds.

So that’s a brief introduction to the hematic constitution.

Watch for the next installment where we’ll talk about the eye that is partway between blue and brown - known as biliary.

I’m thankful to have iridology as a primary assessment tool - here’s one example why.

A case study from my client files.

Male
Late 70’s

My assessment began as he walked into the office.

He was overweight by at least 30 lbs which made me wonder about blood sugar balance.

He walked gingerly with short steps which suggested joint pain.

Simply by observing him as he walked in then examining his irises and sclerae the questions started flowing.

When was his cholesterol checked last?
There were indications in his corneas that suggested cholesterol had possibly been elevated for some time.
He pulled recent labs up on his phone.
Cholesterol was elevated even with medication.

Was there a history of anything cardiovascular?
He had specific indicators in his irises in the heart zones and he had blue-gray patches in his sclera.
He shared that he had a diagnosis of congestive heart failure.
He was on a few different meds to try to assist his heart function and regulate his blood pressure.

How was his blood sugar?
Between his weight (and obvious waist measurement over 40’) and some key indicators in his irises and sclerae, I would have been surprised if he said his blood sugars were fine.
They weren’t. He was on metformin.

How about joint issues?
Yes, pain in his knees when he walked.
His irides also suggested this predisposition.

I didn’t have to name any diseases. I simply needed to understand. Observing him and his eyes, then asking the appropriate related questions, guided what we needed to do.

Specific diet work (which none of his other health care providers has recommended) and gentle daily physical activity (we started with walking five minutes, three times each day) caused the weight and inches to start coming off, eased the pain in his knees, and brought his blood sugar and cholesterol down. His doctor was impressed and more importantly, he felt younger than he’d felt in years!

My favorite non-lab ways of assessing? Iris assessment and focused conversation.

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.

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.
