The Mast Cell 360® Method: Healing MCAS in the Right Order for Sensitive Bodies
When you have Mast Cell Activation Syndrome (MCAS), it may feel like you react to everything you try.
You may have tried detox protocols, supplements everyone recommends, or things you even know you need!
But instead of feeling better, you feel worse.
Sound familiar?
Conventional protocols and approaches can backfire spectacularly when you are sensitive.
And it isn’t that most practitioners don’t want to help. Most just don’t understand sensitivities well enough to know how.
Each person is unique. And finding what works for you can take some “trial and see”. We know how frustrating that can be from personal experience.
But we want you to know that it often is possible to make progress! To start feeling better. And to get your life back.
The problem often isn’t that you’re doing the wrong things. It is that they are being done in the wrong order or too fast for your sensitive body.
In this post you will learn:
- Why standard protocols fail sensitive people or often make symptoms worse
- The essential 5 steps of the Mast Cell 360® Method
- The critical first step for sensitive people—and why order matters
- Why mold matters and when to detox
- When to address things like SIBO, Leaky Gut, Candida, Lyme, etc
- Finding 1:1 support and what to expect with the Mast Cell 360 Clinic

Why Trying to Heal Keeps Backfiring with MCAS
Here’s the truth… most healing protocols weren’t designed for sensitive bodies.
And if your mast cells fire at the slightest trigger, approaches designed for the average person probably won’t work.
Standard protocols flare MCAS because they:
- Don’t account for sensitivity – many supplements or medications include things that are mast cell triggers. Or may even be triggers themselves!
- Move too fast – they use doses at levels meant for people who aren’t hyper-reactive or make many changes all at once. With sensitivities, you need a more personalized, and often lower and slower approach.
- Ignore necessary steps – skipping steps healing from MCAS is like trying to build a house without a foundation.
- Start in the wrong place – most jump straight to aggressive detox, gut work, or parasite cleanses before your body is ready.
The result? You’ve likely:
- Spent thousands on doctors with few answers
- Spent hundreds on supplements that now sit in a cupboard (the supplement graveyard)
- Pushed through detox reactions that left you struggling to function
- Been told you’ll “feel worse before you feel better,” only to keep feeling worse
- Heard “it’s all in your head” (it’s not)
It can start to feel like nothing actually works.
And MCAS rarely comes alone. You’re likely dealing with 1 or more of these, too:
- Food intolerances like:
- Chronic infections – Lyme, EBV, Long Covid
- Gut problems – Leaky Gut, SIBO, Candida
- Dysautonomia / POTS
- Ehlers-Danlos Syndrome (EDS)
- Hormonal imbalances
- Autoimmune issues
- Various toxic loads
- And more!
With so many pieces to the puzzle, knowing where to start can feel overwhelming.
Finding what works can feel like an exhausting guessing game.
And finding help can feel nearly impossible.
So, what do you do? Where do you actually start?
That’s exactly why the Mast Cell 360 Method was created. We needed this information on our own healing journeys! And now it is the functional foundation of our clinic.
We want to share this and hope it will help you, too. Like it helped Sarah.
When Doing “Everything Right” Goes Wrong
Meet Sarah (not her real name). Her story is very common in our community. You might even recognize yourself here!
Sarah had been dealing with mystery symptoms:
- Food intolerances
- Headaches
- Itching
- Gut issues
- Fatigue
- Insomnia
- Reflux
- Anxiety
- And more
And the symptoms lead to a long list of diagnoses.
Her doctor put her on vitamins for deficiencies, antihistamines, and medication for sleep.
Within 2 weeks, Sarah could barely get out of bed. Her headaches were worse than ever. She developed crushing fatigue and such intense brain fog she couldn’t remember her own address.
Her practitioner adjusted doses and took her off the sleep meds.
After another week of feeling worse, they stopped the vitamins and tried a different antihistamine. That didn’t go any better.
After a few more visits, her doctor was apologetic but out of ideas. And Sarah didn’t feel better.
She didn’t know she was reacting to a lot of the fillers and ingredients in the medications. Or that some vitamins can even be mast cell triggers. She didn’t know she also had Histamine Intolerance.
It took her a long time to calm down what she now knows was a mast cell flare.
She’s been working with our clinic for about a year now and is doing much better! She’s even using some of the same supports her practitioner originally suggested.
What went wrong?
Sarah’s body needed stabilization first. And someone who understood sensitivities.
She needed:
- More support for her nervous system and mast cells
- A low and slow approach to onboarding things
- Identifying and reducing triggers
- Time to stabilize
- And eventually gentle detox (not heavy protocols)
We hear similar stories over and over again.
It’s why the Mast Cell 360 Method exists.
Keep reading to learn how we use this approach and why it works even when others have failed.
Understanding the MC360 Method: 5 Steps Built for Sensitive Bodies
The Mast Cell 360® Method is our clinic’s foundational framework.
It is a proven and personalized roadmap built specifically for sensitive bodies.
Pioneered by Beth O’Hara through her own journey and refined over the years by a team who has both lived experience with Mast Cell Activation Syndrome and Histamine Intolerance and the experience of working with thousands of clients.
The 5 Steps in the Mast Cell 360 Method are:
- Stabilization ← We Start Here
- Gentle Detox
- Clean Up – remaining pieces like Lyme, SIBO, Candida (although these often clear up on their own with detox!)
- Rebuilding
- Optimizing
As you just read, our practitioner team has their own personal experience with MCAS, Mold Toxicity, and other chronic illness.
We know what it’s like to be in your shoes looking for answers and reacting to everything. And that is one of the things that sets us apart as a team.
The next is where we start: Stabilization.
Why We Start with Mast Cell Stabilization
Stabilization is an important first step when you are sensitive!
Think of it this way. If your symptom level is already 9 out of 10 every day, you have no room to ride the ups and downs that naturally come with detox.
It will push you into a flare.
But if you can bring your symptom level down to a 6 or 7, or even a 5, first? Now you have some room.
Let’s take a closer look at each step in the MC360 Method next, starting with what happens in Stabilization.
Step 1: Stabilization and Building Your Foundation for MCAS Healing
Stabilization is where healing truly begins when you are sensitive.
And it’s a step most practitioners skip entirely.
Here’s what stabilization looks like…
Nervous System Rebooting for Mast Cell Activation Syndrome
Your mast cells and nervous system are intimately connected.
If your nervous system is stuck in constant fight-or-flight mode, your mast cells stay activated.
Learning some tools to help support your nervous system can really help your mast cells!
Related Post: Nervous System Balance (including tools we recommend)
We focus on 4 key areas with the nervous system:
- Limbic System Rewiring – helps restructure neural pathways in the brain that can keep reactivity high.
- Vagal Nerve Toning – helps build resilience and the ability to shift with stress back to calm.
- Structural Evaluation – many people with MCAS have structural issues in their bodies (often in the neck) that put pressure on the vagus nerve.
- Emotional Health and Trauma – processing both ‘big T’ and ‘little t’ trauma and getting support for the emotional challenges of living with complex illness is imperative to healing.
Next up are supports that further help calm and stabilize mast cells.
Mast Cell Calming and Stabilizing Support
You just read about how working on your nervous system can help calm and stabilize your mast cells. Stabilizing often requires layers.
Other mast cell supports might be supplements or medications. What works best for each person is very individual.
Commonly, this may include things like:
- Baking Soda
- DAO (diamine oxidase) – to help reduce histamine
- Perilla Seed Extract
- Other supplements
- H1 and H2 antihistamines
- Other prescription medications

Supports like these act as bridges to help manage symptoms while you heal.
But remember, the goal isn’t lifelong symptom management. It’s removing what’s driving your symptoms in the first place.
Doing this allows many people to dramatically reduce or even stop extra supports over time.
Another question we get a lot is gut support! Let’s look at how that plays a role in stabilization next.
Supporting Gut Function and Motility with MCAS
Gut issues are very common with MCAS, including motility issues like constipation or loose stools. And both have impacts on healing.
When you have constant loose stools, you don’t absorb nutrients.
When you’re not having daily bowel movements, toxins get reabsorbed.
The goal is daily bowel movements that are well formed and easy to pass.
Key supports here include working on:
- Establishing daily elimination
- Calming gut inflammation
- Improving nutrient breakdown and absorption
- Digestive enzymes (as tolerated)
- HCL (stomach acid support)(as needed)
- TributyrinX (as needed)

While we do support the gut during stabilization and detox, rebuilding comes after detox. You can’t finish cleaning up until the trash (mold) is taken out.
Now that we’ve looked at gut support, let’s look at environmental toxins next. These are big mast cell triggers! And often part of the root causes behind MCAS.
Removing Environmental Triggers
The idea behind identifying and removing environmental triggers in general is to take out things that are putting a lot of pressure on your body and detox pathways.
Pulling stressors out and reducing toxins allows your body to start calming down. It doesn’t have to work so hard.
And it’s the next step in giving your body the room and resources it needs to start healing instead of just coping.
So, what toxins do we recommend people look at?
We see Mold Toxicity in well over 95% of our clients.
Mold toxins (mycotoxins) are toxic gasses released by molds. And mold spores are like tiny mold seeds. And they both cause big dysregulation in your nervous system and immune system, including mast cells!
They can be completely hidden and odorless. Your body also stores mold toxins from past exposures for decades. And you can even start growing mold inside you!

Mold:
- Uses up resources your body needs to heal
- Clogs up your detox pathways
- Throttles energy production
- Constantly triggers and dysregulates your nervous and immune system
- And more
Removing it is key to allowing your body to start functioning well again.
Trying to make progress without addressing the mold often keeps people stuck or circling back around to the same problems over and over again.
And, like you just read, it’s a factor in nearly every case we work with.
So, now, this is one of our first steps—checking your environment and testing your body are part of our process.
Other environmental triggers we address:
- Air quality (not just mold)
- Water quality
- Toxin and chemical exposures (food, body, home)
- EMFs / Electromagnetic Fields (for those who are sensitive to them)
Additional Stabilization Supports
Some people need additional supports to stabilize.
Sleep, adrenal, hormone balance, and other supports may be added as you are ready for them on a case-by-case basis.
This isn’t about doing everything at once. It’s strategically layering in what you need.
Step 2: Gentle Detox for Mast Cell Activation Syndrome
Once you’ve stabilized, we begin focusing on gentle mold and mycotoxin detox.
What does gentle mean?
It means going slow enough for your body. And supporting and adjusting rather than pushing through reactions or flares.
Gentle detox includes:
- Targeted binders for mycotoxins
- Lymph supports and movement, as tolerated
- Liver and Gallbladder supports, as needed
- Kidney support, as needed
- Antimicrobial / Antifungal supports, as needed
- Biofilm busters, if needed (there is a reason these typically come last!)
Why this order?
When you start pulling toxins out, if detox pathways aren’t open, and binders aren’t ready, toxins pile up.
You’ll end up in a toxic soup. And that will trigger mast cells.
Sensitive people simply need a more gentle, carefully structured approach.
There’s another benefit to removing the mold in step 2. Let’s look at that next!
Step 3: Clean Up and Addressing What Remains After Mold Detox
Once you remove the mold, your immune system and other body systems often come back online.
This means that many infections and other issues clear up on their own after detox! For the issues that remain, they become much easier to address.
By this point, you’ve also learned how to onboard things in a mast cell-aware way and understand your body’s signals.
So, in this third step, we clean up anything remaining like:
- SIBO
- SIFO
- Chronic infections (Lyme, Bartonella, Epstein-Barr)
- Parasites
- Remaining hormone imbalances
- Remaining sleep issues
- Heavy metals (usually toward the end)

It isn’t that none of these are supported earlier in the process, they just aren’t the main focus.
You can think of it like putting out house fires before you start rebuilding. Now it’s time to rebuild!
Step 4: Rebuilding
With your toxic load reduced and infections addressed, now you rebuild!
This is where you will focus on things like:
- Mitochondrial support
- Gut lining repair and microbiome rebalancing
- Bone health support
- Strengthening your immune system
At this point in the journey, you have addressed a lot of what was keeping you stuck. And you can really focus on the deeper details of long-term health.
You’re probably feeling pretty good here, too!
Step 5: Optimizing Long-Term Wellness with Mast Cell Activation Syndrome
At this point, you’re chronic symptom-free with a deep understanding of your individual triggers and tools.
Optimization includes genetic support, long-term wellness, and preventive health strategies.
You can think of it as fine-tuning your personal maintenance routine.
Now that the steps have been laid out, let’s look at why this works for sensitive people when you have tried so many things that didn’t.
Why the MC360 Method Works for Sensitive People When Others Have Failed
So, what actually makes this method work when other protocols and approaches have failed?
There are a few key differences:
- We prioritize stabilization – most practitioners skip straight to detox or antimicrobials. We create the buffer you need to actually heal.
- We address root causes, not just symptoms – no band-aid approach here. We find what’s driving your symptoms and remove it, so you’re not dependent on endless supplements.
- Built by sensitive people, for sensitive people – every team member has lived experience with MCAS, Mold Toxicity, or chronic illness. We know what it’s like, and we work together to help you!
- Multi-practitioner model – multiple sets of eyes on your case. We meet for client reviews, learning from each case, and each other. You benefit from collective expertise, not just one perspective.
- No “pushing through” – we don’t push through reactions or detox symptoms. We listen to your body and help you adjust accordingly.
Going slow enough for your sensitive body is how you actually heal.
Our motto is, “Slow is fast, and fast is slow.”
Real Results from Our Team
As you read earlier, our team has lived this healing journey.
Here are some of the stories from our team:
Kimberly (Lead Practitioner) Experienced 7 years of searching for answers before discovering MCAS and Mold Toxicity. She dealt with Lyme, SIBO, POTS, anaphylaxis, head-to-toe hives, chronic fatigue, and severe immunosuppression. She now works, travels, goes to the gym regularly, and even ran a 5K! She used to have a laundry list of supplements and medications to take daily, and now she is off all mast cell stabilizing supports.
Jamie (Health Coach) Symptoms began in 2008, followed by years of known mold exposure from 2009–2016 that no practitioner addressed. She struggled with recurring SIBO, autoimmune conditions, and chronic fatigue, trying countless approaches without lasting relief. After discovering Mast Cell 360 in 2022, she spent 1.5 years in gentle detox and nervous system work. Today, she considers herself chronic symptom-free and is off most supports. She is also able to work out consistently and gain muscle for the first time in her life.
Kam (Health Coach) In early 2022, after a vaccine reaction and a hidden mold exposure, her health collapsed. She was down to zero foods, facing a feeding tube, and nearly bedbound. She was living with over 50 severe symptoms daily across multiple systems (brain, nervous, gut, heart, and more) and no answers. When she found Mast Cell 360’s website, she began piecing things together. And that understanding changed everything. While she’s still on her healing journey, she avoided the feeding tube, eliminated or significantly reduced most symptoms, can eat a variety of foods again, works full-time, and continues to steadily build on her progress.
Our own results drive the passion we have for this work.
And these examples are far from the only ones. We see this pattern repeated across our team, with our clients, and within the community.
Now that you understand the method, you’re probably wondering about your next steps. While we wish there was a one-size-fits-all plan, healing MCAS requires personalization.
For some people, all the free information we provide for our community is enough to get on the road to recovery! And our courses help many.
For others, they really need 1:1 help to untangle it all. This is especially true for complex cases.
If you find yourself in the group who needs or wants 1:1 guidance, we do have options for working with our clinic team. Read more about our clinic next.

Common Questions About the MC360 Method and Clinic
We get a lot of questions about working with the clinic. Here are the most common ones:
Do you work with related conditions?
- Yes, we work with a wide variety of conditions alongside MCAS! Some conditions are outside our scope. The first question in our pre-screener asks about these to make sure we’re a good fit and can truly help you.
What do appointments look like?
- We review your history first. And initial appointments are 90 minutes so we can really go over and understand your case. Follow-ups are 50 minutes. And there are shorter check-ins available when you need them.
How long does healing take?
- Healing depends on many factors, like duration of exposures, toxic load, sensitivity level, ability to remove triggers, etc. Some people see significant improvement within months. Others need 2 to 3+ years of consistent work.
- We go at your pace! This is about sustainable healing. The good news is that you don’t have to get to the end to start feeling better! That happens along the way.
Final Thoughts: Hope for Your Healing Journey
If you are reacting to everything, unable to tolerate even gentle supplements, or feeling like you’ll never get better, we want you to know there is hope. Please know you are not alone.
Our team has been where you are. We’ve been bedbound. We’ve reacted to water. We’ve lost hope and wondered if we’d ever have our lives back. And we’ve seen thousands of people in those shoes.
And we’re all here to tell you: healing is possible.
It’s not about pushing harder. It’s about showing up for yourself in small ways. And about doing the right things in the right order, at a pace your sensitive body can actually handle.
The choice you make today to take your next step, whatever that looks like for you, is what moves you forward.
Be curious. Be gentle with yourself. Keep going.
We’re here when you’re ready.
