LATEST STORIES
Over the last several years, I’ve worked with countless clients who show up with symptoms that don’t follow a clear diagnostic trail. They’ve been told they’re fine—even when they feel anything but. Swelling in the face or hands. Chronic chest pressure. Rapid weight gain. Brain fog. Resting heart rates that spike without warning. Skin flushing. Waking up feeling wired or inflamed.
Sound familiar?
These aren’t random issues. They’re signs that something deeper in the terrain is off—specifically, in a part of the body that most of medicine still isn’t talking about: the lymphatic system.

When Histamine Builds and the Body Can’t Keep Up
We now know that SARS-CoV-2—especially its spike protein—can hijack normal immune signaling. It binds to ACE2 receptors (abundant in the heart, lungs, and gut), disrupts mast cells, and interferes with DAO, the enzyme that breaks down histamine. It even increases the number of histamine receptors across tissues.
In other words:
We’re making more histamine,
Breaking down less,
And becoming more sensitive to what’s already there.
What you get is a perfect storm of reactivity—where a single food, scent, or stressful conversation sets off flares: shortness of breath, insomnia, arrhythmias, bloating, itchiness, or that “swollen” feeling so many people describe but can’t explain.
But here’s the deeper problem: histamine doesn’t just disappear. It has to be cleared. And it relies on three major systems to do that: the lymphatics, the liver, and the kidneys.
When any part of that system gets congested—whether due to viral load, stress, toxins, or underlying genetic tendencies—histamine gets trapped. It builds. And suddenly, the body is reacting to everything.
Restore. Release. Renew.
Supporting your lymphatic system may be the key to easing swelling, reactivity, and chronic post-viral symptoms.
The Lymphatic System: More Than Just Drainage
We tend to think of the lymph as a passive drainage channel, but it’s much more than that. It’s our immune superhighway. It carries white blood cells, picks up inflammatory waste, filters pathogens, and helps eliminate everything from dead cells to mold toxins to—yes—histamine.
Here’s the kicker: the lymph has no pump.
It depends on your breath, hydration, movement, and parasympathetic tone. And after COVID, when the body’s been in chronic fight-or-flight and inflamed for months—or even years—that system often just isn’t moving.
When lymph flow stagnates, you start seeing:
Puffy face or hands
Occipital pressure and sinus congestion
Atrial arrhythmias, heart palpitations, or chest burning
General malaise and hypersensitivity
Swelling with no clear explanation
These aren’t just leftovers from an illness—they’re signs the body hasn’t been able to resolve fully what it has been fighting.

The Clearance Triad: Lymph, Liver, Kidneys
Within The Cochrane Method®, I teach that real healing happens when we support what I call the clearance triad:
1. The Lymphatic System
Collects and transports immune debris, histamine, and toxins from every tissue.
Dumps into the bloodstream near the left clavicle.
2. The Liver
Processes histamine, metabolizes estrogen, and clears toxins.
If it's genetically sluggish or overburdened, you’re in what I call the “spin cycle.”
3. The Kidneys
Filter water-soluble waste and inflammatory fragments.
When dehydrated or backed up, they contribute to edema, fatigue, and even blood pressure swings.
If one of these systems slows down, the other two are forced to overcompensate. And when all three are overloaded? That’s when symptoms become chronic, confusing, and resistant to treatment.
How We Restore Flow—Without Forcing the Body
What we don’t want is to push the system harder with aggressive detoxes or binders that overwhelm an already taxed terrain. Instead, we use gentle but intelligent tools to invite the body back into rhythm:
Marshmallow Root: Soothes inflamed mucosa and calms histamine activity.
Burdock Root: A traditional lymph and kidney support, rich in anti-inflammatory compounds.
Castor Oil Packs: Promote lymphatic drainage, especially when applied over the liver and clavicle.
Dry Brushing: Stimulates superficial lymph vessels to enhance fluid movement.
These aren’t quick fixes. They’re real solutions that respect the body’s design. Remembering that everyone is bio-individual.
COVID’s Hidden Legacy
From histamine overload to heart flutters, post-COVID symptoms often trace back to systems we’ve overlooked.
Food That Matches Function
Even the best protocol will fail if the diet continues to clog the system. Sulfur-rich vegetables, high-histamine leftovers, and fermented or sprouted foods are common health foods—but in a sensitive body, they’re inflammatory landmines.
Instead, I guide clients toward a low-histamine, low-sulfur Wildatarian® diet, customized to their gene expression and recovery phase:
✅ Freshly cooked, lean proteins (like wild boar and bison)
✅ Low-sulfur veggies (zucchini, carrots, green beans)
✅ Low-oxalate starches (purple potatoes, brown rice)
✅ Non-fermented fruits (peeled pears, grapes, cherries)
❌ No leftovers, bone broth, garlic, onion, or crucifers
❌ No heavy fats or fermented foods
This is not restriction. This is precision.
We are living in a time where long COVID, histamine issues, and chronic inflammatory symptoms are becoming the norm. But that doesn't mean they’re irreversible.
The truth is: these symptoms are not random. They’re the language of a terrain in distress. And the path forward isn’t about chasing diagnoses—it’s about restoring flow.
Because when we support the lymph, liver, and kidneys in harmony, the body doesn’t have to be pushed.
It just needs space—and guidance—to remember how to heal.
