🚫   Contraindications - the Herxheimer Reaction

"The body's genetic detoxification software was designed to handle naturally-occurring toxins, not the 125,000+ industrial chemicals present in our environment today. Poor diet, pollution, medications, stress, trauma, infections, chemtrails and electromagnetic radiation all contribute to the toxin build up
which cause damage to the body's cells."

Dr Mark Hyman, founder and medical director of The UltraWellness Center (IFM)

A quick note about the word “detox”

You may notice I occasionally use the word 'detox', and whenever I do, it tends to attract a bit of pushback. Some readers are quick to point out that in their opinion, “detoxing” isn’t a real thing.

And in a way, they’re right  but the backlash is mostly cultural rather than scientific. Over the years the word has been hijacked by the juice-cleanse and influencer wellness world, so critics understandably assume it means the body is somehow “full of toxins” and needs a dramatic purge, which isn't always the case.

Scientists themselves tend to avoid the word as well, partly because the body already has clearly defined "detoxification" systems – the liver, kidneys, gut and lymphatic system – and partly because the term is often used rather loosely in commercial health marketing.

But - the biological processes themselves are absolutely real.

Every second of every day our cells are breaking down damaged components, recycling useful materials, and clearing away metabolic waste - the body is constantly maintaining and renewing itself.

So, if the word "detox" doesn't sit well with you, you might prefer to think of it instead as cellular clean-up or metabolic housekeeping – both of which describe the same underlying biological processes, and terms which I use in this page as well.

I sometimes liken it to the body’s own version of stable management – clearing out what no longer belongs, recycling what can still be used, and keeping the internal environment tidy so everything else can function properly.

And on that note… let’s begin! Here's the EquiNatural take on cellular clean-up / metabolic housekeeping.

Planet Earth was created perfect. And so were we.

Then came all the things man created in the name of progress and a bright future, some of which turned out to to be not so good. Things like carcinogen-filled foods, dangerous air pollution levels, radiation-emitting technology, chemically soaked farmlands... the list goes on.

The leading health experts all agree - fact is, we’ve poisoned Eden.

For millions of years horses evolved out on open landscapes, wandering mile after mile across steppe, tundra, swamp, desert, grazing a wide variety of low-nutrient plants and roughage, drinking clean water and breathing clean air. Their bodies developed astonishingly efficient systems for dealing with life – breaking down food, managing microbes, processing plant toxins, and naturally clearing away the endless stream of waste products produced by everyday metabolism.

Nature mapped everything out back them, but the world our domestic horses live in today is not quite the same world they evolved from.

An organism, i.e. us humans, our horses, our dogs/cats etc., are all perfectly designed to handle a normal amount of natural toxins, but the massive amount of man-made toxins we’re exposed to today in our modern world is far too much for our bodies to manage. According to the Environmental Working Group there are over 85,000 man-made chemicals currently approved by the Big-Wigs for use in our western world, and this number is rapidly increasing.

We all know that toxins accumulate in the body and are the cause of various health problems; certainly in recent years we've learned a great deal about how they affect the body, where they originate, and how to improve the body's ability to detoxify. But even at low levels, toxic exposures contribute to the development of a variety of chronic health conditions, with fatigue, endocrine disruption, and chronic degenerative diseases being three commonly recognised areas where toxins build up throughout the body and the disease process begins.

In our modern world, we're all exposed to a far more complex array of toxic compounds in our air, water, and food than ever before, so understanding toxicity and taking practical steps to improve biotransformation and elimination are both essential and critical parts of any integrative approach to health and well-being.

You've probably heard of carcinogens - toxins that have been confirmed to cause cancer. However, all toxins will contribute to a toxic body, whether we like it or not. For our horses, fertilisers, herbicides, fungicides and pesticides are just a drop in their world’s toxic soup, and they're very relevant to why our horses' health becomes compromised, because they - like us - swim in it every day.

Modern agriculture, chemical sprays, industrial pollutants, processed feeds and medication residues have all slowly crept into the environment. None of these things necessarily cause immediate catastrophe on their own, but together they create a background load that the body now has to deal with.

And yet - horses are incredibly resilient creatures, tougher than we often give them credit for. But there’s no escaping the fact that their natural in-built clean-up systems now have more work to do than nature originally designed them for. Understanding how those systems work, and how we can support them, is therefore one of the most useful pieces of knowledge any horse owner can have. Because… when the body’s internal housekeeping runs smoothly, almost everything else will run smoothly too.

That said - there’s a simple way to fight back. There's an amazing little-known, built-in, all-natural mechanism that’s hidden in each and every "body" - a very sophisticated, natural cellular-repairing system that directly protects the body against toxins. Meet the liver, kidneys and lymph nodes, or as I call them, the '3-Amigos'. All we have to do is activate them.

Meet the “Three Amigos”

Every horse comes equipped with its own internal cleaning crew - I like to call them the 3-Amigos - the liver, the kidneys, and the lymphatics.

Between them, these three systems work tirelessly in the background, filtering the blood, processing unwanted compounds, and escorting waste safely out of the body through its various exit routes – all without us even noticing.

Waste leaves the body through several pathways - the bowel,  urine, breath, and through the skin's sweat glands. If everything is working properly, this orchestra plays along quietly in the background like an efficient cleaning service that never clocks off. Like having an internal Dyson permanently running – silently hoovering up the debris before it has a chance to accumulate.

But imagine what your home would be like if you didn’t clean it for a few weeks. If mine's anything to go by - with dogs, cats (and their feathered or furry gifts), free-range chooks who wander in whenever they feel like it, plus the yard detritus and mud that dumps itself inside every time we open the front door, it doesn't bear thinking about what state my house would get into if I didn't get the Dyson out. Even then I find it hard enough to keep on top off.

The body works in exactly the same way - except instead of dust and rubbish, it’s dealing with metabolic waste, dead cells, microbial debris and environmental compounds that need to be filtered, processed, then shown the door.

Thankfully our horses come equipped with those three remarkable housekeeping systems – the liver, kidneys and lymphatics – constantly clearing the internal environment so everything keeps running smoothly. But when the workload increases, that’s usually when the small health niggles begin to appear.

And unlike at home, we can’t simply open the windows, wave a feather duster around and hope for the best. The body’s clean-up crew have to be able to do the job properly.

When the body gets overloaded

Every living being produces waste - digestion produces waste, exercise produces waste, cells constantly produce waste as they carry out their daily work. Even those unfriendly microbes in the hindgut 'burp' out their waste - lactic acid to be precise, which causes that uncomfortable belly bloat we've all seen in our horses.

All completely normal - the body is designed to deal with it. Think of every cell in the body as a tiny factory – and remember, factories produce useful products, but they also create waste that needs to be removed.

The body’s filtration and elimination systems exist to deal with that waste before it begins interfering with normal function. The challenge comes when additional environmental load piles on top of those normal processes.

Here's just a sample of what our modern-day horse will encounter:

• agricultural sprays on pasture and hay
• moulds in forage
• higher sugar and starch levels than they’re evolved to eat
• environmental pollutants
• medication residues
• metabolic by-products from intense training

None of these things automatically spell disaster, but collectively they add to the body’s workload like traffic building up on a motorway.

When traffic flows freely, cars move smoothly and everyone reaches their destination without trouble. But if a lane becomes blocked or there’s an accident ahead, vehicles start stacking up behind it.

Those metabolic housekeeping ('detox') pathways work in much the same way. If the elimination systems are flowing well, waste moves through and out without fuss. But if one part of the system slows down, the backlog begins to build – and pressure starts appearing elsewhere in the body.

That’s often when we see the familiar low-grade health niggles - a dull, scurfy, itchy skin and coat, puffy legs, digestive issues - all due to stagnation in the detox pathways.

"Detoxing" deconstructed

One of the most common mistakes people make when thinking about "detoxification" is imagining it as one dramatic event - a weekend cleanse, a quick purge, or a sudden reset. But biology rarely works that way.

The body’s clean-up systems are interconnected, and waste moves through them in a very specific sequence like a plumbing system. If the pipes are clear and the drains are flowing, everything runs smoothly. But if the main drain becomes partially blocked, the water doesn’t disappear properly - it backs up into the system.

The body works in much the same way.

Waste must move downstream through the elimination pathways, and if those pathways are congested, pushing more waste into the system can actually make things worse. This is why herbal "detox" programmes are traditionally approached step by step.

First we stabilise the gut  function, because this is the body’s primary exit route. Once the digestive system is functioning properly, then we move to the liver and kidneys, the two major filtration organs responsible for transforming and removing metabolic waste.

Finally we support the circulatory systems, particularly the lymphatic network, which carries cellular debris and immune waste away from the body's tissues.

Working in this order allows the body to move waste through the system efficiently rather than allowing it to recirculate. It’s less about forcing toxins out and more about restoring the natural flow of elimination.

So let's look at it in order.

Stage 1 - the gut: the first line of defence

No coincidence - the digestive tract is not only responsible for breaking down food – it is also the body’s main exit route for solid waste - think of it as the body’s rubbish chute.

The horse’s digestive system is an extraordinary piece of biological engineering –

• Digestion begins the moment forage enters the mouth, then chewing mixes the food with saliva and prepares it for swallowing.
• From there it travels to the stomach, where digestive enzymes start to break it down, and the stomach acid disinfects it all.
• Next comes the small intestine, where nutrients are absorbed into the bloodstream.
• Finally, the forage fibre digesta reaches the hindgut – the horse’s vast fermentation chamber – where billions of fibre-fermenting microbes convert the fibre into the energy that fuels the horse’s body.
• What remains eventually leaves the body through the bowel.

When digestion runs smoothly, everything flows beautifully. But if the gut becomes irritated or the microbial balance shifts, the system slows down. If you’ve ever been behind a door trying to get out and the exit's blocked, this is a perfect analogy for why a metabolic clean-up is so important; toxins need to get out of the body's exit routes, but if the exits are blocked, waste that should be leaving the body simply queues up instead. And when waste can’t leave efficiently, it ends up circulating around the body again and triggering inflammation.

Which means... the clean-up crew suddenly have much more work to do. Which links us nicely to...

Stage 2 - the liver and kidneys: the body's master detoxification organs

The liver is the primary decontaminating workhorse, which breaks down every item that's ingested into the body to molecular size - think of the liver as the Royal Mail’s main sorting office. Anything that is ingested by the body – whether through breath, food, water or skin absorption - will end up at the liver for processing - nutrients, hormones, environmental compounds, microbial fragments – are inspected, processed and directed to the correct destination.

Unless they're undesirables, that is - those that can be converted into water-soluble forms are passed to the kidneys; fat-solubles are packaged up and returned to the digestive tract so they can exit through the bowel.

Meanwhile the liver is also managing an astonishing number of other tasks.

• Purifying the blood
• Producing hormones
• Releasing glucose into the bloodstream to provide steady energy
• Produces a steady, constant trickle of bile bile for fat digestion

In other words, it isn’t simply a detox organ - it’s one of the central command centres of metabolism.

Meanwhile, working alongside the liver are the kidneys, which contain around a million microscopic filtration units called nephrons.

These tiny filters constantly sift through the bloodstream, separating useful nutrients from waste products. Valuable molecules are returned to circulation, while water-soluble waste is passed out through the urine. In doing so the kidneys help regulate fluid balance, electrolyte levels and blood pressure.

You could think of the kidneys as the body’s recycling department – ensuring that nothing useful is thrown away while unwanted compounds are safely removed.

Stage 3 - the lymphatics – the body’s drainage canal

Running alongside the blood circulation is another system that many people overlook - the lymphatic system. If blood delivers nutrients, lymph is the body’s toxin drainage canal.

It collects cellular waste, immune debris and microbial fragments from tissues, and filters them through the lymph nodes where immune cells inspect everything passing through, endeavouring to kill off any unfriendly bacteria or viruses.

But - unlike blood, lymph has no pump. It relies entirely on movement to keep flowing - which is why horses standing still in stables for long periods often develop what we see as swollen or “puffy” legs, aka stagnant lymph.

Lymph is like butter - move,  warm it up, and it flows. Don't move, and it goes cold and stagnates. In short, movement keeps lymph flowing, and flowing lymph keeps tissues clear.

Doing it naturally – how herbalists view a "detox"

Before we get into the practical “how-to” side of things, it’s helpful to pause for a moment and look at how herbalists tend to think about "detoxification" in the first place, because the philosophy is a little different from the conventional pharmaceutical model most people are used to.

The simplest way to understand herbs is to stop thinking of them as drugs. They aren’t. They are, in essence, nature’s concentrated foods.

And yet - for millions of years plants have been quietly developing their own survival strategies. Unlike animals, plants can’t run away from danger. They can’t escape mould, insects, microbial attacks or environmental stress. Instead, they evolved something rather clever.

They developed an extraordinary library of protective chemicals known as phytochemicals.

These compounds allow plants to defend themselves against moulds, microbes, insects, environmental toxins and weather stress. In other words, plants have their own internal defence system. And here’s the interesting part - horses evolved eating those plants.

As grazing herbivores, horses have spent millions of years consuming grasses, herbs, leaves and roots that naturally contain these protective compounds. Over time their bodies adapted to use those plant chemicals in supportive ways.

So when we feed herbs, we’re not introducing something alien to the horse’s system - we’re simply reconnecting the horse with a nutritional relationship that has existed for millennia. Those plant phytochemicals can gently interact with many biological pathways at once — supporting digestion, circulation, immune balance and the body’s natural clean-up systems.

This is very different from the way modern pharmaceuticals tend to work.

For most of the last century many medicines we know today were originally derived from plants - e.g. Aspirin from Filipendula ulmaria, Metforming from Galega officinalis. Over time, however, pharmaceutical science moved toward isolating single active compounds and reproducing them synthetically. The result is a made-in-a-lab molecule designed to produce a very specific effect on a specific symptom or process.

This is how drug companies make their money. They take a natural plant compound, tweak it slightly in the lab so it becomes legally “theirs”, patent that modified version, and then sell it as a drug.

But here’s the catch. You can’t patent something that nature already made - things like vitamins, hormones, or the natural compounds found in plants. And because those substances can’t be owned or monopolised, they’re never going to generate the kind of profits pharmaceutical drugs do. Which, in turn, means there’s far less commercial incentive to spend millions funding large peer-reviewed studies on them.

Herbs work differently. Instead of delivering one isolated chemical, a medicinal plant contains hundreds of naturally balanced compounds working together. Those compounds interact gently across multiple metabolic pathways, supporting the body’s own regulatory systems rather than forcing them in a particular direction.

That said, conventional medicine usually does what it does very well, especially in accident and emergency - thank all the gods for morphine, so say all my previously broken bones. But as we know, while powerful, pharma drugs are  synthetic; they're generally designed to simply block or interrupt biological pathways, they come with side effects, and they leave toxic residue behind.

The body is better able to use plants because their natural 'whole-body' phytochemicals spread across numerous metabolic pathways. The body recognises them, knows what to do with them, and uses them where they’re needed without risking side effects.

In practical terms, that means the body recognises these plant compounds as food-like signals. It knows what to do with them, and it can utilise them in ways that support its existing physiology. Which is why herbalists tend to think less in terms of “attacking a problem” and more in terms of supporting the body’s natural processes.

Detoxing is not a sprint

One of the biggest misconceptions about detoxification is that it should happen quickly.

In reality, the body doesn’t tend to respond well to sudden, aggressive interventions. The clean-up systems work best when they are supported gradually and consistently over time.

Think of it less like a dramatic house clearance and more like regular housekeeping - a steady approach allows the body to adjust as waste begins moving through the system. Energy levels stabilise, digestion improves, and the immune system has a chance to rebalance.

When people ask how long a proper clean-up takes, the honest answer is: it depends.

If the system has been under strain for a long time, it may take months for the body to fully restore balance. In some cases the process can take a year or more. That’s why herbalists often rely on tonic herbs — nutrient-rich plants that gently support metabolic processes over time. Once the system has been cleaned up, continuing with a daily tonic approach can help maintain that balance.

It’s a bit like taking a daily multivitamin. You’re not trying to force change overnight — you’re simply giving the body consistent support so it can maintain its natural equilibrium.

The body also benefits from natural breaks. With my own horses I tend to take one day off per week from herbal supplements — usually Sunday, if I’m honest, because it allows me the luxury of a slightly slower morning. Some people prefer one week off in every five - others adjust depending on the season.

The exact schedule matters less than the principle: the body should always be allowed time to function independently and strengthen its own regulatory systems.

Is it time for a system reset?

For horses that appear to be struggling with a heavier toxic load, a more structured approach can sometimes be helpful. And our OptimaCARE programme was designed with this sequence in mind.

It’s a three-stage, month-long programme that supports the body’s natural elimination pathways in the order they normally operate.

• Stage 1 focuses on the digestive system, supporting the gut and its microbial balance.
• Stage 2 turns attention toward the liver and kidneys — the body’s main filtration organs.
• Stage 3 supports circulation, particularly the blood and lymphatic systems that carry metabolic waste away from tissues.

Each stage runs for ten days with a short break in between, allowing the body time to adjust before moving on to the next phase.

By the end of the process the aim is simple - to restore what I sometimes call the horse’s “inner engine” — a digestive system that can efficiently extract nutrients, a filtration system that can process metabolic waste, and a circulatory system that can keep everything moving smoothly.

When those systems are working together properly, the body is far better equipped to maintain its own balance.

Don’t knock sweating

One of the most overlooked elimination pathways is something horses do naturally every day - sweating.

Sweat is often viewed simply as a cooling mechanism, but research in human physiology shows it can also play a meaningful role in removing certain compounds from the body.

A well-known investigation called the BUS study (Blood, Urine and Sweat Study) examined the elimination of environmental toxins through different pathways. Interestingly, the results showed that sweat can contain measurable amounts of certain compounds, including BPA, phthalates and even heavy metals.

In some cases, levels of metals such as aluminium, cadmium and lead were actually higher in sweat than in urine or faeces. What this suggests is that perspiration may contribute to the body’s overall elimination processes. For horses, regular movement and exercise naturally stimulate sweating, which is another reason why movement is so important for metabolic health.

Of course, sweating patterns can also tell us a lot about the body.

Excessive sweating, or sweating that seems out of proportion to the level of work, can sometimes signal that something deeper is going on. Likewise, a horse that struggles to sweat normally may be showing early signs that its internal regulation systems need support.

As every experienced horse owner knows, learning what is normal for your individual horse is often the most valuable diagnostic tool you have.

Occasionally horses may sweat unevenly, such as across one shoulder or one side of the body. In traditional medicine systems this is sometimes linked to meridian imbalances, and therapies such as acupuncture or shiatsu can sometimes be useful in restoring balance.

Either way, the key point is simple.

Sweating isn’t something to fear - it’s one of the body’s natural ways of keeping the internal environment clean and balanced.

The bottom line

Every horse already possesses an extraordinary internal cleaning system - the liver, kidneys, lymphatic system and digestive tract constantly working together to maintain balance. Our role as caretakers is not to override these systems - it’s simply to support them.

Good nutrition, regular movement, low stress - and when needed, appropriate botanicals working in synergy that the body recognises and understands.

When these foundations are in place, the body often has an impressive ability to restore its own balance. Which, when you think about it, is exactly how nature designed it in the first place.

At the end of the day, most horse owners aren’t trying to master biochemistry – we simply want our horses to feel comfortable in their own bodies. When the body’s natural housekeeping systems are running well, the signs are usually obvious.

It’s not magic – it’s simply what happens when the body is able to keep its internal environment clean, balanced and flowing as nature intended.

🚫 Contraindications – the Herxheimer Reaction

Sometimes we all have to feel worse before we feel better - whether horse, dog, or human.

First up, don't panic! "Herxing" is usually very short lived - 2/3 days at most, but it can look alarming - us humans tend to get horrible migraine-like headaches for a couple of days while our metabolic housekeeping systems are sorting out the cellular recycling and renewal. It simply means a rare, but occasional, short-term "re-toxification".

Simply put, it’s an overload reaction - it’s basically an immune system reaction where, as the body detoxifies, an overload of toxins overburden the blood supply while stuck in the queue waiting to be eliminated.

The good news? Herxing is actually a sign that the detox is working - and it can also carefully be managed. 

Warning - don't detox horses during onset laminitis due to the risk of re-toxification.

But no question - herxing is one of life’s cruel  jokes: your horse’s programme is going great and you’re feeling optimistic about finally getting them out the other side. Then without any warning, their symptoms take a turn for the worse.

Herxing, as it's commonly referred to, was first observed in syphilis patients by dermatologists Adolf Jarisch and Karl Herxheimer in the late 1800s/early 1900s, who during 'treatments' noticed that sufferers sometimes got worse before they got better.

The phenomenon was originally dubbed the Jarisch-Herxheimer Reaction, and has since been shortened to Herxheimer Reaction or simply - herxing. The classic explanation of a herx reaction is that when certain bacteria are killed off, say, by an antibiotic, parts of dead bacteria called endotoxins are shed. These endotoxins then circulate throughout the body and cause a fairly intense, but short-lived inflammatory reaction, which temporarily makes the war against the toxins that’s already going on inside the body feel a whole lot worse.

In general, herx reactions are more common and more intense with conventional antibiotic use than with use of herbs. With herbs, the bacterial die‐off is more gradual and the immune response is less intense. That said, while there’s no clinical research on the prevalence of herxing in horses, you may witness general ill-at-ease, anything from joint/muscle pain, itching/scratching, sweating, or gut imbalances amongst others. In humans, chronic headaches are a common sign.

This is a perfectly normal - and even healthy - reaction, indicating that the parasites, fungi, viruses, bacteria and other impurities are being effectively killed off. Although it may appear that the detox isn’t working, a noticeable herx reaction is a sign that a healthy, positive detox is taking place. Worsening presentations don't indicate failure of the detox - just the opposite.

So your horse is herxing – now what? Once you've determined it's a herx reaction, you’re probably wondering how long this is going to last, and what to do with it. There’s no simple answer – it’s usually just a few days, but try to keep up with the therapy at a dose your horse can handle. If you feel you need to, lower it - you can always increase once your horse is over the Herx hump. Worst case? Stop the detox for a few days.

In the meantime, here are a few ways to ease the discomfort:

• Continue the programme at tolerable doses. Adjust as needed and gradually increase as symptoms improve.
• Hydration is crucial as it aids lymph flow, promoting waste removal - make sure your horse is getting salt in their feedbowl.
• Address cellular stress factors – give your horse a magnesium wash. Dissolve a mug of Epsom Salts and a few drops of lavender essential oil in a bucket of water. This not only helps with removing toxins from the body but also helps soothe tight muscles.
• You can also alleviate the discomfort with natural anti-inflammatories, such as our DuoBute.

We’ve had only one client years ago who reported concernable agitated behaviour from her usually very calm, sweet, elderly chap, who turned into a fire-breathing dragon during his programme. He was half-way through Stage 2 (liver/kidneys) and no doubt experiencing a tough time, but as his owner was really worried at the 360-degree character change, plus any potential injury risk, understandably she decided to pull the plug.

Other than this one instance, we’ve not had any client report any significant side effects in 10-years or so - only beneficial improvement at the end of the programme. To reassure you, we've got many wonderful testimonials on theOptimaCARE product page, but do get in touch if you have any questions.
