Iridology Education

Iridology Education Learn how to do iridology and qualify to be certified by the International Iridology Practitioners,

focused on sharing the most up-to-date iridology information for holistic practitioners

04/10/2026

If you’re an IIPA-certified iridologist who wants to move from listing iris markings and remedies in a 1:1 fashion to feeling confident in understanding how markings relate to each other and your client’s symptoms, this message is for you.

Body Systems Iridology and Herbology is an 11-module, self-paced program designed specifically for practitioners like you.

Here’s what’s inside:
• Pre-recorded video lessons you can watch anytime, over and over for review
• Downloadable charts, checklists, and supplement recommendation guidelines
• Anatomy & physiology refresh all 11 major systems
• Real-world correlation training: how multiple markings work together
• Practical protocol recommendations using food, herbs, nutrients, and lifestyle
• Self-marking quizzes to evaluate your learning
• CEUs with downloadable certificates for each successfully completed module

Total time investment: about 30 hours at your own pace

And because I know real learning deepens in community, you also get access to twice-monthly group livestreams where we answer your questions and coach you on your client cases.

No more wondering if you’re “reading it right.”

No more generic recommendations.

Just clear, connected, clinical iridology you can use immediately.

On Monday, April 13 at 6pm MDT, I’ll walk through a real client case and give you a tour inside the student portal. Drop a comment below and I'll send you the regsitration link for the walk-through webinar!

Should you focus on one marker or all of them?

As an IIPA-certified iridologist, I can tell you a single marker rarely tells the whole story, but neither does it serve any useful purpose to try to list or comment on every marking.

And that realization can bring with it a lot of frustration in practice.

Clients don’t arrive with one isolated symptom. They bring a web of complaints. What starts as one concern often expands as you listen carefully during the appointment.

It’s tempting to treat each iris marking and symptom as separate issues and hand over a long list of recommendations. But when you do that, a few things usually happen:

You end up with a lengthy supplement list and multiple dietary changes
Appointments run long and you’re not always compensated for the extra time
Your client feels overwhelmed and struggles to follow through
Many clients who feel overwhelmed simply don’t return

The iris already shows you the epigenetic connections. The real challenge is learning how to read the full story those markings are telling - how to know which markings are important in the moment and how to prioritize them. That’s exactly what Body Systems Iridology and Herbology was created to teach.

In 11 self-paced modules you’ll discover:

A clear review of anatomy & physiology for each major body system
The key markings that relate to each system

How those markings interact across systems (the critical piece most iridologists never learn)

Practical, effective recommendations using diet, herbs, vitamins, minerals, and lifestyle

You’ll move from “there’s a kidney sign” to “here’s the complete connected picture” and gain the confidence to build simple, step-by-step programs your clients can actually follow.

The result? Deeper, faster results for your clients and real confidence for you in every consultation.

I’ll share the full course details on Friday.

With love and insight,

There’s a piece missing from most iris analysis today.

We’ve all seen the iridology “readings” on social media that feel more like paint-by-numbers than real health assessments. Someone posts eye photos with very little background information and asks, “Tell me what my eyes say.”

Comments quickly appear like: “You have a kidney issue” or “You need a deep cleanse” — often based on a single marker.

One marker = one problem. It sounds simple, but that’s not how real clinical iridology works.

You see, it's by going beyond 1 marker - 1 problem that you begin to uncover a person's epigentic tendencies.

I know. As an IIPA-certified instructor with 45 years of iridology, herbology, and nutrition training under my belt I’ve worked with thousands of clinical clients. I’ve learned this truth: A kidney marker is rarely just about the kidneys. And a kidney symptom is almost never only about the kidneys either.

Real iridology is about connecting the dots — often multiple symptoms and multiple iris markings — across body systems.

When you understand that every body system interacts with the others, everything changes. You stop guessing. You create clear, cohesive, root-cause programs instead of chasing isolated symptoms or overwhelming your clients.

This is exactly what most iridology courses don’t teach.

And it’s the clinical confidence I want every IIPA-certified iridologist to have.

That’s why I created Body Systems Iridology and Herbology — to give every IIPA-certified iridologist the clinical confidence they deserve.

Join me for a free course tour and live case study on Monday, April 13 at 6pm MDT. I’ll answer all your questions about the course.

We have just scraped the tip of the iceberg so far in our mini-class videos. Working through concepts at such a high level might have you feeling a lack of cohesiveness. We’re going to fix that today with a case study primarily using what we’ve learned so far in the mini-class videos. The video is only 9 minutes long as I talk you through an iris analysis.

First - remember, there is an efficient order to doing an iris assessment - and order that will help you to keep your thoughts and assessment organized.

We do a quick review of the order of things in this video and follow it up with a iris assessment of a client who has hematogenic irides.

Today, we’re taking a look at my favorite iridology map.

Notice how uncluttered it is compared to many charts you've seen. We avoid over-dividing the iris into micro-segments because constitutional iridology focuses on broader organ reaction fields and inherent tendencies—not minute anatomical slices. This simplicity reduces interpretive errors and keeps our focus on the big picture.

The iris divides into organ reaction fields, much like reflexology maps organs onto the feet. You'll also see the seven concentric zones:

Zone 1 — Stomach and gastric mucosa; reveals predispositions to stomach acid levels or stomach lining issues.
Zone 2 — Intestinal tract and mucosal integrity.
Zone 3 — Nutrient absorption across the intestinal wall into core blood circulation and core lymph
Zone 4 — Specific organ predispositions to challenges.
Zone 5 — Bone and structural tissue tendencies.
Zone 6 — Surface blood and lymph circulation.
Zone 7 — The "ultimate detox zone": inherent integrity of skin and other epithelial tissues.

Iridology is never "paint by numbers." A single marking doesn't tell the full story.
For instance, a closed lacuna in one liver reaction field suggests an inherent predisposition to liver challenges. There are three liver fields—seeing lacunae in more than one liver reaction field amplifies significance. Layer in a pigment freckle, a transversal, or correlating symptoms, and the pattern becomes actionable.
We look for convergence: two or three markings pointing to the same issue to give depth to the questions we ask.

When you combine solid knowledge of anatomy, physiology, and constitutional iridology, you can trace symptoms back to their roots—distinguishing genetic/inherent weaknesses from lifestyle-induced burdens.

Next week, I'll share a complete case study from intake to iris analysis to recommendations. Stay tuned!

If you're a health professional interested in adding constitutional iridology to your skills set send me a direct message. I'd be happy to discuss upcoming courses or how this tool can enhance your assessments and client work.

Looking forward to your comments and questions.

What does a leaf-shaped opening in the iris tell us about constitutional health?

These posts are intentionally brief—because when it comes to iridology, we could spend hours on any one topic. For now, we’re just scratching the surface.

Today: lacunae. Watch this short video to see examples of lacunae.
https://youtu.be/fQM6BY0Yqbo

At a quick 30,000-foot view, lacunae are one of the structural markings we evaluate in constitutional iridology.

In some older styles of iridology they were called lesions—which is unfortunate terminology. That word suggests pathology or abnormal growth, and that’s not what these markings represent.
Lacunae are inherent structural features of the iris.

They are genetically determined and often trace back three to four generations.

A lacuna does not mean someone has a health condition. What it tells us is something different—and very useful.

It points to constitutional predispositions.

In other words, it gives us clues about where the body may be more vulnerable under stress.

Some people have many lacunae. Others have only a few.

And as often happens in iridology:
the fewer there are, the more significant each one becomes.

Lacunae are structural. They don’t disappear with diet changes, supplements, detox protocols—or dancing naked under a full moon.

They can, however, appear to shift slightly depending on pupil size.
There are many types of closed lacunae. Some of the more commonly observed include:

• Simple closed lacuna

• Asparagus tip lacuna

• Polypose lacuna

• Shoe lacuna

The defining feature of a closed lacuna is its outline. Most resemble the shape of a leaf or flower petal within the iris fibres.

Each variation provides a different piece of constitutional information.

When assessing a lacuna, we also consider:

• pigment inside the lacuna

• the degree of shading within it

• the colour and thickness of the outline

• pigments attached to the border

And, as always in iridology, no single sign is ever interpreted in isolation.

We always consider the client’s current concerns, symptoms, diet, lifestyle patterns, and the other iris indicators that help corroborate what we’re seeing.

Iridology is not a diagnostic tool.

What it does beautifully is help guide better questions—which leads to better individualized recommendations.

In the next installment we’ll take a look at pupil size and shape to see what kind of information they add to the assessment.

If you’re curious about what it takes to learn iridology at a clinical level, and how it can integrate with the modalities you already practice, hit me up. Let’s talk.

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!

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.
