The Science
The ENCORE Method Perspective on Chronic Sinus Congestion
Biological Mechanism
MARCoNS (biofilm bacteria) in nasal cavity
In plain English: MARCoNS — multiply antibiotic-resistant coagulase-negative staphylococci — can colonize the deep nasal cavity and wrap themselves in a protective biofilm. This slimy matrix shields the bacteria from both the immune system and antibiotics, so infections smolder rather than clear. The biofilm also fuels ongoing inflammation and can further disrupt regulatory hormones like MSH, creating a self-sustaining cycle of congestion that resists conventional treatment.
The Mold Connection
How Mold Drives Sinus Infections
Mold-driven immune suppression, particularly low MSH, creates the perfect conditions for MARCoNS to take hold, because weakened mucosal defenses can't keep the nasal cavity clear. Once established, the biofilm bacteria drive inflammation that suppresses MSH further, deepening the vulnerability. This is why chronic, treatment-resistant sinus congestion is such a common feature of mold illness and so often loops back to the same immune dysregulation.
The Path Forward
What Helps with Sinus Infections
The functional-medicine goal is to disrupt the biofilm so defenses and treatments can finally reach the bacteria. Traditionally used for its antimicrobial properties, Supreme Nutrition Melia supplies plant compounds that may help break down bacterial biofilms as part of a broader protocol. Alongside that, reducing mold exposure, restoring MSH and immune regulation, and supporting mucosal health tend to matter more than any single agent. Persistent sinus problems warrant evaluation, and a MARCoNS swab can guide a targeted plan.

Why Sinus Infections Matters Beyond the Symptom
Sinus Infectionsisn't an isolated glitch—it's often connected to broader patterns across three foundational systems.
Nervous System
Persistent symptoms keep the autonomic nervous system stuck in survival mode—blocking repair.
Immune Function
Chronic inflammation and immune dysregulation ripple outward, fueling symptoms across the body.
Cellular Health
Mitochondrial strain and membrane damage reduce the cellular energy needed to heal.
When we address the root cause rather than mask symptoms, we often see improvements across all three—simultaneously.
The Method
The ENCORE Method Approach
For conditions like Sinus Infections, Dr. Kim's ENCORE Method works across all systems simultaneously—not just one symptom at a time.
“Rather than chasing individual symptoms, we address all layers simultaneously—guided by your body's capacity and response.”

Testing & Assessment
A functional workup often includes a MARCoNS nasal swab — a deep-culture test that identifies the resistant, biofilm-forming bacteria driving treatment-resistant congestion. Measuring MSH is useful, since low levels both invite colonization and result from it. A urinary mycotoxin panel gauges the mold burden behind the immune suppression, and environmental testing (ERMI or HERTSMI-2) can pinpoint an ongoing source. These build a picture together.
Common Questions
Chronic Sinus Congestion: Frequently Asked Questions
Why don't antibiotics clear my sinus congestion?
Biofilm-forming bacteria like MARCoNS wrap themselves in a protective matrix that shields them from both antibiotics and the immune system, so standard courses can't reach them. That's why congestion smolders through repeated prescriptions. Addressing the biofilm and the underlying immune suppression is usually needed for lasting relief.
What is MARCoNS?
MARCoNS stands for multiply antibiotic-resistant coagulase-negative staphylococci — resistant bacteria that can colonize the deep nasal cavity in people with mold-related immune suppression. They form protective biofilms and can further lower MSH, helping explain why sinus problems become chronic and hard to treat in mold illness.
Can I test for it at home?
MARCoNS requires a deep nasal swab that reaches the back of the nasal cavity, so it's typically collected and sent to a specialized lab rather than done casually at home. A practitioner familiar with mold illness can arrange the swab and interpret it alongside your other markers.
Will my congestion come back?
Recurrence is more likely if the underlying immune suppression and ongoing mold exposure aren't addressed, since those conditions allow biofilm bacteria to recolonize. Many people get durable relief once the environment is remediated and immune regulation improves, though this varies and is best managed with a qualified practitioner.
