The Core Idea
The post-pandemic health signal is not isolated. It appears across systems, age groups, and disease categories — and the value lies in recognising the pattern before reacting to it.
— The thesis behind every part of this work
The NO Secrets: Nitric Oxide Solutions from Ancient Medicine
Sixteen chapters · Lumienta Publishing, London
New book · with John McMillan
Every strand of this research runs back to the same thin tissue.
COVID-19 as an immune-mediated vascular disease. The endothelial dysfunction behind Long COVID. Blood supply to the ageing brain. Follow any of those strands far enough and they arrive at the single-cell lining of every blood vessel — and at the molecule that governs how it behaves.
The NO Secrets is the practical companion to that work: nitric oxide, the practices that support it, and an honest account of which of them the evidence actually holds up.
Sixteen chapters, sixteen civilisations
One practice per chapter — a food, a way of breathing, a habit — traced to the culture that arrived at it before anyone could explain why.
A clinical perspective in every chapter
What the evidence genuinely supports, where it thins out, which drug interactions matter, and who should be careful.
Written with John McMillan
Co-authored with his brother and published by Lumienta Publishing, the London house behind all three of their books.
Two Lenses, One Signal
Most people read this story as either a clinician or a data analyst. The work happens where the two meet.
01 · The Clinician
What it means for one person
Sitting with patients whose symptoms don't fit neatly into a single diagnosis — and helping them understand the pattern behind a confusing clinical picture, so they can engage more effectively with their own care.
See the clinical approach →02 · The Researcher
What it means across a population
Tracking the same disturbance at scale — in hospital admission patterns, chronic disease trajectories and immune-inflammatory mechanisms — to ask what is actually changing, and why it is being missed.
Explore the research →The bedside raises the question. The data tests it. Few people work in both places at once.
COVID STORM
A mechanism-first framework
- Immune dysregulation as a starting point, not a side note
- Gut–immune–inflammation interactions
- Endothelial and vascular involvement
- Macrophage-driven inflammatory persistence
- Links to chronic, metabolic and neurodegenerative patterns
The Framework
Start with the mechanism, not the headline.
Much of the public conversation about post-pandemic health jumps between isolated symptoms and isolated studies. A framework does something different: it explains how the pieces might connect.
The aim is not a single answer, but a way of thinking clearly enough to interpret new evidence as it arrives.

Common Questions
Who he is, and how to work with the material.
Who is Dr Philip McMillan? +
A physician and researcher focused on post-pandemic health patterns. His work bridges clinical interpretation of complex individual cases and population-level analysis of how disease patterns appear to be shifting since the pandemic, supported by peer-reviewed publications on COVID-19 immunology and Long COVID mechanisms.
What is the COVID STORM framework? +
A mechanism-first way of understanding how immune dysregulation, inflammation and related processes may connect across many different conditions — used to interpret evidence rather than to make fixed claims.
Can he be my doctor? +
