There is something strange and unknowable about fungi. They exist on the threshold between worlds - neither truly plant nor animal, though closer to animals than plants nevertheless. Fungi have a peculiar relationship with decay, thriving where life has begun to dissolve and breaking down what was once whole into something entirely new. Though the irony in this, being that fungi were the sole organisms which enabled plant life to thrive out of water, is not lost on me. They are the silent architects of the forest floor, the unseen networks beneath our feet, the quiet recyclers of death into life. It is no surprise, then, that in homeopathy, the fungal remedies sit on the edge of understanding, resisting the rigid categorisation that we attempt to impose upon them.
It was this very elusiveness that drew me towards Spectrum Materia Medica: Fungi by Frans Vermeulen. This book is not just a compilation of remedies - it is an exploration of the fungal kingdom through the lens of homeopathic understanding and under a Friesian categorisation, a deep dive into the mysterious role of fungi in both nature and human health. As I immersed myself in its pages, I felt the same sense of uncanny recognition that I have come to associate with the deeper levels of homeopathy, where remedies are not merely substances but archetypal expressions of something much greater.I do however have strong feelings about plant life being an order of its own, with fungi being a sub order of this in terms of homeopathic learning. In my mind, it should be the opposite!

The Threshold Between Worlds
Reading through Vermeulen’s work on fungi in homoeopathy, I was struck by the recurring theme of liminality - the state of being on the threshold between two realities. Fungi, in nature, exist in this space; they are decomposers, breaking down what is dying and transforming it into something new. They thrive in places of transition - on rotting logs, in damp corners, in the liminal spaces between life and death. It makes perfect sense, then, that homeopathic fungal remedies often hold relevance for people who themselves exist in a state of transition - whether physically, emotionally, or most importantly psychologically.
Fungal remedies have a particular affinity for deep-seated chronic conditions, those illnesses that linger in the body like a half-forgotten shadow. They often present in cases where something refuses to fully resolve - be it an infection that never quite goes away, a state of mind that hovers between clarity and confusion, or a deep-seated toxic burden that the body cannot seem to expel. It is as though the fungi within us echo their role in nature, quietly persisting, waiting for the right conditions to emerge in full force. Indeed, Wren Lloyd has done some great work around molds and fungi in her work here https://homeopathywithwren.podia.com/blog/moldstrep-asd

A Deeper Understanding of Mycotic Remedies
One of the most fascinating aspects of Spectrum Materia Medica: Fungi is the way Vermeulen draws connections between fungal remedies and the broader themes they represent. Each entry is not just a list of symptoms but an exploration of the remedy’s deeper nature - its affinities, its patterns, its story. Reading about Agaricus, for example, (once you get over the Friesian classification!) I was struck by the sheer dynamism of its symptomatology - spasms, jerks, exaggerated movements, a kind of uncontrolled energy that spills over into physical form. It is a remedy for excess and depletion in equal measure, oscillating between states of overstimulation and exhaustion.
Secale cornutum, on the other hand, carries a very different essence - one of constriction, of cold, of a kind of slow, creeping destruction that echoes the ergot fungus from which it is derived. It speaks to conditions where circulation is compromised, where tissues wither away, where the body is gripped by an insidious force that it cannot shake. There is something almost ghostly about its presence in the materia medica, a sense of inevitability, of something creeping just beneath the surface, waiting to make itself known.
Then there is Candida albicans, a remedy that speaks to modern pathology in a way few others do. It is a remedy of imbalance, of the modern condition of excess - excess sugar, excess antibiotics, excess artificiality in diet and lifestyle. It reflects the state of internal dysbiosis that so many people find themselves in today, a system overwhelmed by an unseen but powerful force growing unchecked beneath the surface. Reading Vermeulen’s exploration of Candida, I could not help but feel that fungi, in their homeopathic expression, are deeply tied to the ailments of modernity - chronic, persistent, often hidden, but always present in some form or another. Indeed I feel that much like there is a renaisance of the exploration of fungi in the food and allopathic medical senses, there will also be the same in homeopathic senses in the near future.

The Strange, Silent Wisdom of Fungi
Perhaps what I found most fascinating in Spectrum Materia Medica: Fungi is the way these remedies speak to something ancient and profound, something that predates human understanding but is deeply intertwined with it. Fungi have existed for millions of years, adapting, surviving, and evolving long before we attempted to make sense of them. Their presence in homeopathy feels like a whisper from an older world, a reminder that healing does not always come from the bright, obvious, or tangible forces we try to harness, but often from the quiet, unseen, and liminal spaces in between.
Vermeulen’s book is not just a materia medica - it is an invitation to step into this world, to view fungal remedies not as mere entries in a book but as living, breathing expressions of a greater pattern. It challenges the reader to go beyond the rote memorisation of symptoms and instead see the deeper essence of these remedies, the way they reflect processes far beyond the human body.

Fungi, Homeopathy, and the Future
As I closed the book, I found myself contemplating the broader implications of fungal remedies in homeopathy. In a time where chronic disease, autoimmune disorders, and persistent infections seem to be ever-increasing, perhaps it is no coincidence that fungi - and the remedies they give us - are coming to the forefront of our understanding. They are, after all, nature’s great balancers, breaking down what no longer serves and recycling it into something new. Could it be that, as a species, we are being called to work more closely with these ancient, enigmatic beings - to learn from them, to understand them, to integrate their wisdom into our healing practices?
There is something deeply humbling about this thought. Fungi, in all their mystery, remind us that healing is not always linear, that it does not always come from eradication or conquest, but often from transformation and balance. They teach us patience, adaptability, and the power of working quietly beneath the surface, where true change takes place.
Perhaps, in the end, this is the greatest gift of Spectrum Materia Medica: Fungi - not just an understanding of fungal remedies, but an invitation to step into their world, to embrace the mystery, and to allow ourselves to be guided by the unseen forces that have always been there, waiting just beyond the edge of our understanding.
