Briana Gunn Naturopathy

You’ve tried everything.
You’re still unwell.
You’re ready to change that.

Most practitioners don’t know what they’re dealing with. Lyme, co-infections, toxic mould, and CIRS require a specialist, not a generalist. With 17 years of clinical experience and lived experience of this illness, Bri is one of the most experienced biotoxin practitioners in Australia.

If this sounds like you

Your symptoms are real.
Your diagnosis may have been wrong.

Chronic fatigue, fibromyalgia, CFS, MS, MND, and a range of neurological and autoimmune diagnoses are often applied to patients whose underlying illness remains unidentified. When standard investigations return normal results and first-line treatments fail to produce meaningful improvement, the possibility of a biotoxin-driven illness (Lyme disease, tick-borne co-infections, or toxic mould) warrants careful clinical assessment.

These are not rare conditions. They are commonly missed.

  • Post-exertional malaise and unrefreshing sleep
  • Cognitive impairment — memory, processing, word-finding
  • Migraine, vestibular dysfunction, or visual disturbances
  • Peripheral neuropathy, paraesthesia, or burning pain
  • Migratory joint or muscle pain without structural cause
  • Gastrointestinal dysmotility, bloating, or food reactivity
  • Anxiety, mood dysregulation, or treatment-resistant insomnia
  • Histamine intolerance or mast cell reactivity
  • Air hunger, orthostatic intolerance, or dysautonomia
  • Night sweats or cyclical symptom patterns
  • Multiple chemical sensitivities or EMF reactivity
  • Dismissed, misdiagnosed with fibromyalgia, CFS, MS, or MND

In complex chronic illness, it is rarely a single root cause. Biotoxin-driven pathology typically involves multiple co-occurring infections, impaired detoxification, immune dysregulation, and nervous system dysfunction, all of which must be addressed in the correct sequence for meaningful recovery.

Conditions treated

Specialist care for conditions
most practitioners don’t understand.

Briana Gunn Naturopathy is one of Australia’s most experienced clinics for biotoxin illness. Each of the following conditions requires precise clinical knowledge, tailored protocols, and experienced management, not a generic approach.

Lyme Disease & Tick-Borne Relapsing Fever

Lyme disease is caused by Borrelia burgdorferi and related species, transmitted through tick bites. In Australia, the existence of locally acquired Lyme disease remains contested in mainstream medicine, yet tick-borne relapsing fever caused by other Borrelia species is documented and, clinically, the presentation is indistinguishable from that of patients infected overseas.

Bri has 17 years of clinical experience managing both acute and chronic Borrelia infection. She contributed to the 2025 Australian Senate Enquiry on tick-borne diseases and is one of a small number of practitioners in Australia with the depth of knowledge required to manage complex, long-standing cases.

  • Cyclical fevers, night sweats, and profound fatigue
  • Joint pain, muscle aches, and nerve pain
  • Cognitive impairment and neurological symptoms
  • Immune dysregulation and multi-system involvement
  • Persistent symptoms following standard antibiotic treatment
Bartonella

Bartonella is one of the most prevalent and underdiagnosed tick-borne co-infections. It is also transmitted by fleas, lice, and sandflies, meaning many patients have no known tick exposure. Bartonella has a particular affinity for the nervous system, connective tissue, and vascular endothelium, producing a distinctive and often severe clinical picture.

  • Shin pain, rib pain, or sub-periosteal pain — a hallmark presentation
  • Neuropsychiatric symptoms: rage, anxiety, obsessive thinking
  • Connective tissue laxity, joint hypermobility
  • Skin manifestations including stretch marks and rashes
  • Burning or electrical sensations in the extremities
  • Severe insomnia and sympathetic nervous system activation

Bartonella is frequently missed or mistaken for a psychiatric disorder. Accurate clinical recognition and targeted antimicrobial herbal protocols are essential.

Babesia

Babesia is an intraerythrocytic parasite. It infects red blood cells, producing a malaria-like illness that is frequently undetected on standard blood panels. It is one of the most debilitating co-infections and significantly complicates recovery if not identified and addressed.

  • Air hunger: a sensation of not getting enough air despite normal oxygen saturation
  • Drenching night sweats and cyclical fevers
  • Profound fatigue, disproportionate to activity
  • Haemolytic symptoms: pallor, shortness of breath, weakness
  • Symptom cycles correlating with the moon phase
  • Poor response to Lyme protocols without Babesia being addressed

Babesia requires specific antiparasitic protocols distinct from antibacterial treatment. Missing this co-infection is one of the most common reasons patients fail to improve.

CIRS: Chronic Inflammatory Response Syndrome

Chronic Inflammatory Response Syndrome (CIRS) is a systemic, multi-symptom illness caused by exposure to biotoxins, most commonly water-damaged buildings producing mycotoxins, but also certain bacteria, algae, and other organisms. It occurs in genetically susceptible individuals whose immune systems cannot clear biotoxins normally.

CIRS is defined by a dysregulated innate immune response that perpetuates systemic inflammation even after the original exposure is removed. Without targeted treatment, it does not resolve on its own.

  • Fatigue, weakness, and post-exertional malaise
  • Cognitive impairment — brain fog, memory loss, difficulty concentrating
  • Mood disturbance, anxiety, and depression
  • Musculoskeletal pain, headaches, and sensitivity to light
  • Gastrointestinal symptoms and food reactivity
  • Immune suppression and recurrent infections
  • Hormonal dysregulation

CIRS is frequently misdiagnosed as fibromyalgia, CFS, or depression. Accurate assessment includes HLA-DR genetic typing, visual contrast sensitivity testing, and a thorough environmental exposure history.

Toxic Mould Illness

Exposure to water-damaged buildings and the mycotoxins produced by toxic mould species, including Stachybotrys, Aspergillus, Penicillium, and Chaetomium, can produce severe, multi-system illness in susceptible individuals. Mycotoxins are potent immunotoxins, neurotoxins, and endocrine disruptors.

  • Neurological symptoms: brain fog, memory impairment, tremor
  • Immune dysregulation and autoimmune-like presentations
  • Respiratory symptoms, sinus congestion, and chemical sensitivity
  • Hormonal disruption — thyroid, adrenal, and sex hormones
  • Skin symptoms, rashes, and hypersensitivity reactions
  • Severe fatigue and sleep disturbance

Recovery requires identification and removal from the source of exposure, followed by a structured mycotoxin elimination protocol. Attempting antimicrobial treatment without first addressing mould exposure and drainage pathways consistently produces poor outcomes.

Mycoplasma & Stealth Infections

Mycoplasma species, including Mycoplasma pneumoniae, M. fermentans, and M. hominis, are cell-wall deficient bacteria that evade standard immune surveillance and antibiotic treatment. They are frequently found as co-infections in patients with Lyme disease and other biotoxin illnesses.

  • Chronic respiratory symptoms, persistent cough
  • Profound fatigue and immune suppression
  • Neurological involvement: brain fog, mood changes, nerve pain
  • Joint and muscle pain
  • Recurrent illness and poor treatment response
Parasitic Infections

Intestinal and systemic parasitic infections are far more common in Australia than standard medical practice accounts for, and are significantly underdiagnosed using conventional stool testing. In patients with biotoxin illness, parasitic burden adds substantial immune load and disrupts gut integrity.

  • Cyclical symptom flares — often correlating with the lunar cycle
  • Gut dysfunction: bloating, altered motility, abdominal pain
  • Immune suppression and recurrent infections
  • Skin symptoms, itching, and histamine reactivity
  • Fatigue and nutrient malabsorption

Parasitic infections must be addressed using targeted antiparasitic protocols at the appropriate stage of treatment, after drainage pathways are open and the body is prepared to tolerate the die-off response.

EBV & Viral Reactivation

Epstein-Barr virus (EBV) reactivation is extremely common in patients with biotoxin illness. The immune suppression produced by chronic infection and mycotoxin exposure allows latent viruses to reactivate, compounding fatigue, lymphatic burden, and overall immune load.

  • Profound fatigue, particularly following any physical or mental exertion
  • Lymphadenopathy and sore throat
  • Liver involvement and elevated inflammatory markers
  • Mood disturbance and cognitive symptoms
  • History of glandular fever with incomplete recovery

EBV reactivation rarely resolves without addressing the underlying immune suppression. It is a secondary priority in the treatment sequence, addressed after drainage and primary infections.

How treatment works
The Biotoxin Breakthrough Method,
built over 17 years.

Most approaches fail because they treat infections before the body is ready. The Biotoxin Breakthrough Method follows a precise clinical sequence: each step creates the conditions for the next to work.

01
Eliminate

Optimise your elimination pathways and remove exposures to toxins, moulds, and inflammatory triggers. Your body cannot detoxify what it cannot eliminate. This step is non-negotiable: drainage before killing, always.

02
Support

Support your body to reduce daily suffering, prevent further damage, and prepare your immune system to tolerate targeted treatment. Mitochondrial function, nervous system regulation, gut integrity, and hormonal balance are addressed here.

03
Exterminate

Target infections directly with precision practitioner-grade herbal protocols — Lyme, Bartonella, Babesia, Mycoplasma, parasites, and EBV. Chosen specifically for your infections, your sensitivities, and your stage of recovery. Not a generic protocol.

04
Rebuild

Rebuild from the damage done. Balance hormones, restore gut health, calm stress responses, and address anything still unresolved. Sonja and Aryana support the emotional and nervous system dimensions of recovery in this phase.

Frequently asked questions

Everything you need to know
before you book.

Does Lyme disease exist in Australia?
Yes. Tick-borne relapsing fever and other Borrelia species have been documented in Australian patients. Many Australians are also infected overseas. The illness is real, diagnosable, and treatable. Bri contributed to the 2025 Australian Senate Enquiry on tick-borne diseases.
What is CIRS and do I have it?
Chronic Inflammatory Response Syndrome (CIRS) is a systemic inflammatory condition triggered by biotoxins from mould or bacteria. It causes fatigue, brain fog, pain, mood changes, and immune dysfunction. A free 15-minute call with Bri is the best way to find out if this applies to you.
How does telehealth work?
All appointments are via Zoom. You can work with Bri from anywhere in Australia or the United States. Between appointments you have direct WhatsApp access so progress never stops.
How long does recovery take?
Most patients see meaningful improvements within the first 3-6 months and continue to improve throughout a 12-month programme. Complex cases may require longer. Bri is transparent about timelines from the first call.
What testing do I need before starting?
Testing is discussed in your initial consultation. Bri works with what you have and guides further testing where clinically useful. Expensive overseas testing is not a prerequisite to starting care.
Do you ship herbal medicines?
Yes. Practitioner-grade herbal extracts tailored to your exact protocol are shipped to Australia and the United States.
Is there a payment plan?
Payment plans are available on the 12-month Biotoxin Breakthrough programme only. The Herb Subscription and Diagnostic Plan are paid in full. Details are discussed in your free 15-minute call.
Can I work with Bri if I’m seeing other practitioners?
Yes. Many of Bri’s patients continue to work with their GP or specialist. Bri works collaboratively and is experienced at managing complex cases with multiple treating providers.
But I already have a local naturopath?
Keep them. A general naturopath and a biotoxin specialist are not doing the same job. Lyme, co-infections, mould illness and CIRS need a practitioner who treats them every single day, not someone who sees a handful of complex cases a year alongside general digestion and hormone work. Most patients keep their local naturopath for everyday care and bring Bri in specifically for the biotoxin protocol, run over telehealth alongside whoever else is in your corner.
Recovery is not a long shot.
It’s a decision.

1,000s of people who were bedbound, dismissed, and out of options have rebuilt their lives. You don’t have to keep working this out alone.
