Histamine intolerance is typically mild, but Mastocytosis is the most severe form of mast cell disorder—often taking nearly a decade to diagnose. Symptoms can affect multiple organs, from rashes and GI issues to life-threatening anaphylaxis, and standard treatments like low-histamine diets and antihistamines often fail.

Many doctors aren’t familiar with testing or treatment options for mast cell issues like Mastocytosis and MCAS.

Today, I’m joined by Dr. Mariana Castells, a leading expert in allergy and immunology at Brigham and Women’s Hospital. She directs the renowned Mastocytosis Center and the Drug Hypersensitivity and Desensitization Center.

Even if you have histamine intolerance or MCAS, this episode offers key insights on histamine, testing, and finding real relief—because no one should suffer needlessly.

What’s the best treatment for Topical Steroid Withdrawal (TSW)? While answers are still emerging, we’re getting closer.

TSW is a misunderstood, drug-induced condition that goes far beyond typical eczema. Many sufferers feel dismissed by doctors since there’s no formal diagnostic criteria and many dermatologists deny its existence. Yet symptoms like relentless itching, flaking, insomnia, “zingers,” and even depression can be life-altering.

In this episode, I speak with Dr. Olivia Hsu Friedman—a compassionate, research-driven Traditional Chinese Medicine practitioner who reveals how TSW differs from eczema, and explains how Traditional Chinese Medicine addresses the “toxic heat” behind symptoms.

If you’ve been told “it’s just eczema” or feel like nothing is working, this episode offers fresh hope and validation!

Can ChatGPT accurately analyze a GI Map stool test? I put it to the test using my own stool test results—and the outcome was… shocking.

Because more people rely on AI for lab interpretation and even protocols, I thought it would be valuable to see how its advice compares to that of a seasoned clinical nutritionist (with over 8 years of experience).

In this episode, I walk you through my stool test results, ChatGPT’s interpretation, and lastly – the protocol suggested by ChatGPT.

Before you upload any testing to AI – you need to listen to this!

Think you might have IBS or Small Intestine Bacterial Overgrowth—but diet changes aren’t helping?

There’s a lesser-known type of SIBO that’s often missed: Hydrogen Sulfide SIBO.

Unlike the hydrogen or methane types, hydrogen sulfide is a neurotoxin that can trigger strange symptoms—like nerve pain, bladder irritation, or even fibromyalgia-like pain. It also plays a major role in the gut-skin connection.

But it often doesn’t show up on standard SIBO tests, making it hard to diagnose.

I’m joined by Dr. Allison Siebecker (renown SIBO expert) to dive into this complex gut issue that can also play a role in messing up your skin (since SIBO is tied to rosacea, psoriasis, and histamine intolerance).

Wondering if parasites are behind your skin or health issues? With social media buzzing about parasite cleanses, it’s easy to feel confused (or even panicked).

The truth is, not all parasites are harmful—some may even regulate your immune system. But others can silently contribute to chronic hives, cystic acne, and food sensitivities. And a poorly done parasite cleanse can backfire.

Joining me is Robin Foroutan, MS, RDN, an integrative nutritionist and stealth pathogen expert, to help you separate facts from internet hype and explore whether parasites are part of your root cause puzzle.

Peptides for skin and gut health are all the rage—but do they really work?

From BPC-157 to KPV and GLP-1 meds like Ozempic, these compounds are gaining traction for their potential to calm inflammation, support leaky gut, and improve chronic skin issues (psoriasis and eczema). But with so much hype, what’s real?

Joining me is Nathalie Niddam—holistic nutritionist, longevity educator, and host of the Longevity Podcast. She breaks down what peptides and bioregulators are, how they work, and whether they’re worth the investment.

Coffee enemas are hyped online for liver detox and gut health, but the risks are often overlooked.

While influencers claim coffee enema benefits like boosted energy and toxin removal, coffee enemas can actually trigger liver and gut imbalances, toxin buildup, systemic inflammation, and even dependency.

If you're serious about supporting your liver safely, tune in to learn why I don’t recommend coffee enemas — and what to do instead.
