Herbs for ulcers in horses: natural support for treatment

A horse with ulcers rarely tells you about the problem directly. More often, they become fussy at feeding time, lose enthusiasm for work, tense their belly during grooming or seem more “difficult” than usual. You notice the behavioural change but do not always immediately connect it with the stomach.

At such times, many people search for herbs for ulcers and hope for a simple answer. I understand this very well. Everyone wants to help their horse gently, without adding further burdens. However, we need to be honest. Herbs can provide valuable support, but they do not replace diagnosis, veterinary treatment, a well-planned diet and daily management.

It is best to think of them as one part of a dressing. Alone, they will not “fix” the whole problem if your horse still goes for long periods without hay, receives overly rich meals, lives with stress or works beyond their capabilities. However, well-chosen herbs given correctly can improve comfort, support the stomach lining and make the treatment period easier.

Gastric ulcers in horses and natural support methods

After training, your horse approaches the feed bowl, sniffs the feed and walks away. The next day, they are irritable when you tighten the girth, and a few days later they become increasingly fussy. In this situation, many owners look for herbs because they want to help quickly and gently. That is understandable. With ulcers, however, you need to start with the right order of action.

First, assess what you are really dealing with and how serious the problem is. Then agree treatment with your vet. Only on this foundation should you choose nutritional support, including herbs. In practice, it is rather like treating a saddle rub. Protective cream alone will not help if the saddle still presses on the same spot.

People often discuss different causes of ulcers in humans than in horses. For you as an owner, however, the practical conclusion matters most. Herbs can support the lining and improve comfort, but they do not remove the underlying cause if your horse goes for long periods without forage, receives too much starch, lives under stress or works despite pain.

Where to start before reaching for a herbal blend

It is worth organising four areas first. These determine whether herbal support has any chance of helping.

• Veterinary assessment: a horse with suspected ulcers should be examined, especially if they are losing weight, weakening, experiencing recurring colic or eating noticeably less well.
• Treatment plan: if your vet recommends medication, herbs should be an addition rather than a replacement for treatment.
• Feeding: a horse's stomach tolerates constant access to fibre better than long gaps between meals and large portions of hard feed.
• Management: stress, transport, herd changes, intensive work and an irregular routine often sustain the problem despite your good intentions.

This is the starting point.

Where natural support genuinely makes sense

I see the best results when herbs are part of a broader plan. The horse's problem has been diagnosed, the diet is appropriately planned, irritating factors have been reduced and you monitor the response day by day. Then plants with protective or soothing properties can support healing and reduce discomfort.

Not every horse benefits equally. One responds well to a simple mucilage-rich blend, while another first needs better feeding arrangements and less stable stress. It is therefore safer to choose individual, straightforward options than to give several products at once and guess what is actually working.

Natural does not mean without effects on the stomach or the whole body. Herbs can help, but only when chosen for the individual horse and included in a sensible treatment plan.

How herbs may ease gastric ulcer symptoms

A horse with ulcers often does not show the problem directly. They become fussy about food, tense during saddling, more nervous at work or noticeably less interested in hard feed. You then look for something that brings quick, gentle relief. Herbs may help, but their role is supportive. They should reduce irritation and improve comfort rather than replace treatment of the cause.

A simple comparison makes this easier to understand. Damaged stomach lining behaves like a graze on the skin. If something keeps irritating it, healing is slow. If we protect the surface and reduce irritating stimuli, the tissue has better conditions to settle.

A protective effect

This most often involves herbs rich in plant mucilage. On contact with water, they form a sticky, soft solution that coats the lining with a thin protective layer. For the horse, this means less friction and reduced contact between the irritated stomach wall and acidic contents.

It works rather like a gentle dressing from within.

This effect does not remove the ulcers themselves, but may reduce burning, sensitivity and discomfort after eating. In practice, this is precisely why herbs work best when added to a treatment plan already organised by a vet, rather than given haphazardly as a last resort.

Mucilage and tannins: two different functions

Owners often group all herbs together, which leads to misunderstandings. Not every plant helps in the same way.

This distinction matters when choosing a blend. If your horse shows pain or obvious discomfort after a meal, protective ingredients are usually the first consideration. With a complex product, it is worth knowing which ingredient protects, which soothes and which was added solely on the basis of traditional use.

Relief depends on simplicity as well as ingredients

With ulcers, more does not mean better. Several randomly combined herbs, plus a “digestive” supplement and a calming product, are a common recipe for confusion. It then becomes difficult to assess what actually helps and what merely burdens the digestive tract or changes appetite.

It is therefore safer to start simply. One herb or a small, clearly defined blend lets you observe your horse's response. Improved feed intake, calmer behaviour around girth-area grooming and no discomfort after eating provide some indication. If symptoms persist, adding more plants will not solve the problem.

This is important because herbs only make sense as part of the whole picture. Alongside them, you need a fibre-based diet, reduced starch, regular feeding and calm daily management. Without these, even well-chosen herbal support usually achieves less than you expect.

If you cannot clearly explain why you are giving a particular herb, simplify the plan rather than expand it.

The main herbs in the diet of a horse prone to ulcers

For a horse prone to ulcers, think in groups rather than trends. Some ingredients are primarily protective, while others are more soothing. This helps organise the subject and makes decisions easier.

Protective herbs

This is where I most often start the conversation with an owner. If the lining is irritated, we want to protect it as gently as possible.

Marshmallow root is a classic example of a mucilage-rich ingredient. Prepared appropriately, it produces a thick, gentle solution that I liken to a soft dressing for the inside of the stomach. This is why preparation technique matters so much, rather than simply the claim on the label.

Linseed is also among the most practical protective ingredients. Once hydrated, it forms its characteristic mucilage. In horse feeding, this is often more convenient than the more demanding preparation of certain roots and leaves.

Ribwort plantain leaf may be less obvious to horse owners, but herbal medicine materials identify it as useful when a protective effect is desired. It is not a “strong” plant in the sense of a noticeable effect after one serving. Its value lies more in regular use.

Soothing herbs and traditional support

Chamomile is an ingredient almost everyone knows. In practice, it is valued for its gentle, soothing profile and frequent use for an irritated digestive tract. It can be a sensible component of simple blends for sensitive horses.

Calendula is traditionally associated with supporting repair and soothing irritation. It usually plays a supporting rather than leading role in blends for horses prone to ulcers, but can sensibly complement more protective ingredients.

Liquorice has a long tradition of use in “stomach” blends. I approach this ingredient more cautiously because owners readily assume that, being natural, it can be fed indefinitely without restriction. This thinking can be risky.

Aloe vera is often mentioned in discussions of soothing irritation. In practice, use common sense and consider the specific product form, its intended use and your horse's tolerance, rather than treating aloe vera as a universal remedy.

A brief practical overview

How to choose without overcomplicating things

I would not start with six ingredients at once. It is better to answer three questions:

• Does your horse mainly need protection? Mucilage-rich ingredients are usually the starting point.
• Are you looking for a gentle everyday blend? Chamomile or calendula are more often added here.
• Are the ingredients clear? The simpler the initial formula, the easier it is to assess the effect.

If your horse starts a new feed, a new supplement and a new herbal blend simultaneously, nobody can honestly say afterwards what helped and what caused harm.

This is why a sensible approach to herbs for ulcers means choosing for a purpose rather than following a list of fashionable plants. One horse may benefit more from a protective blend, another from a calmer feeding programme with a small herbal addition, while for another veterinary treatment and stress reduction will be crucial, with herbs remaining only an extra.

Using herbs in practice: dosage and preparation

A horse with ulcers may receive well-chosen herbs yet experience little obvious relief if preparation goes wrong. It is rather like feed mixed with too much water or given in an unsuitable form. The ingredients are the same, but the outcome differs.

For a horse prone to ulcers, the plant choice matters, but so do its form, timing and stomach tolerance. Herbs should support treatment and feeding rather than add another uncontrolled variable. The safest approach is therefore to introduce them simply, gradually and according to one consistent plan.

The form affects the action

In practice, I most often encounter four forms:

• cut dried herbs, suitable for soaking or infusing,
• powders, convenient for mixing into mash or dampened feed,
• extracts and ready-made products, useful when you need straightforward dosage,
• ready-made blends, provided the ingredients are clear and you know why each is included.

This is where most misunderstandings arise. You see “herbs for the stomach” and assume they are all prepared like tea. They are not. Mucilage-rich ingredients and ingredients for infusions behave differently.

Not every herb needs boiling water

The simplest rule is this: if a protective effect is the aim, you usually want to extract mucilage. Mucilage benefits from gentle handling. Marshmallow and linseed are therefore more often prepared by soaking or adding water gently, rather than vigorous steeping.

Chamomile is different. An infusion makes sense here because you want compounds that pass readily into hot water. For you as a horse owner, the key is distinguishing two kitchen techniques:

• maceration or soaking, more often used for protective ingredients,
• infusion, more often used for soothing ingredients such as chamomile.

A single mistake may not cause harm, but it can make the herb much less useful.

How to do this practically in the stable

When I include herbs in a plan for a horse with suspected or diagnosed ulcers, I usually follow a few simple rules.

• I start with one ingredient or one small blend, rather than five new products at once.
• I introduce herbs gradually over several days, monitoring appetite, droppings, willingness to eat and response to work.
• I give them with a damp carrier if the horse dislikes the taste or dusty form.
• I avoid giving them on an empty stomach if the horse shows discomfort.
• I record what was introduced and when. Without this, it is difficult to assess the effect honestly.

These are very down-to-earth measures, but they determine whether herbal support helps or merely complicates the picture.

Two simple examples

Marshmallow

Marshmallow works best when preparation encourages the mucilaginous, protective fraction to form. In practice, this usually means soaking in cool or lukewarm water for several hours. The preparation is then given in a small volume, mixed with feed or separately if your horse accepts it well. Pouring boiling water over the root and treating it like ordinary tea can easily lose the very effect you wanted most.

Chamomile

Chamomile is prepared differently. A classic covered infusion, left for a dozen or so minutes and served once cooled, usually works well. This illustrates that “herbs for ulcers” are not a single preparation category. Each has its own preparation requirements.

How much to give your horse

I would not transfer human dosages directly to a horse. They may offer guidance on preparing an ingredient, but are not a ready-made conversion formula. For a horse, you need to consider body weight, the type of stomach lesions, current treatment, diet and whether the problem involves only the stomach or the intestines as well.

A safe starting point is therefore usually a small amount, one product and calm observation. If your horse receives veterinary medication, particularly protective products or acid-suppressing treatments, discuss herb selection with your vet. Herbs should not compete with treatment. They should complement it.

A good herb given in the wrong form works poorly. A correctly prepared herb included in a feeding and treatment plan makes much more sense.

If I had to identify the most common mistake, it would be the belief that simply adding a blend to feed will solve the problem. With ulcers, the entire arrangement matters. The herb, method of administration, feed, feeding routine and veterinary supervision must all work towards the same goal.

Herbs are not everything: the role of diet and management

Your horse receives herbs yet still grinds their teeth during grooming, fusses over feed or returns to discomfort after a few better days. In this situation, the problem usually is not choosing the “wrong herb”. More often, the basics are disorganised. With gastric ulcers, herbs are an addition to the plan, rather than a plan in themselves.

A horse's stomach likes a steady routine

A horse's stomach works almost continuously and produces acid even when the animal is not eating. Long gaps between meals are therefore like leaving an irritated area unprotected. Add large hard-feed portions, rapid eating and a stressful daily schedule, and the lining has little chance to settle.

In practice, organising daily life usually makes the greatest difference:

• constant access to forage or frequent, small portions of hay,
• limiting large amounts of starch in a single meal,
• more fibre, which extends chewing and buffers stomach contents,
• calmer daily arrangements without constant sudden changes.

This works like a dressing that stays in place all day, rather than briefly after giving an extra product.

Diet and herbs should work in the same direction

If your horse has ulcers or a very sensitive stomach, do not build the feeding programme around a herbal blend alone. First, establish the foundation. Feed should be gentle on the stomach, predictable and matched to the horse's workload. This usually means less starch, well-chosen fibre sources, a cautious approach to concentrates and sensible meal distribution throughout the day.

Only against this background do herbs make practical sense. They can support comfort, but cannot undo the harm caused by an empty stomach for half the day or excessive hard feed every day.

Some owners choose ready-made solutions rather than assembling everything from individual ingredients. This can be sensible if the composition is clear and the product fits your vet's or nutritionist's advice. VETfactory offers categories such as feed for horses prone to ulcers and digestive supplements, which you can consider as part of a broader feeding programme. Above all, feed, treatment and herbs should support the same goal.

Mistakes that most often undermine results

Owners rarely cause harm through a lack of care. More often, it comes from rushing or trying to improve everything at once.

The most common problems look like this:

• your horse receives too little hay and spends too long with an empty stomach,
• feed, herbs, training and stable arrangements all change in the same week,
• meals are organised for people's convenience rather than the horse's physiology,
• stress is overlooked, such as conflict with a neighbouring horse, frequent transport, isolation or overly intensive work.

With ulcers, every one of these factors matters. The stomach does not judge which was the “main cause”. It responds to the combined burden.

What produces the best results in practice

A simple, supervised plan works best. Your horse has a consistent daily routine, enough forage, sensibly chosen hard feed and treatment arranged by a vet, with herbs introduced cautiously only afterwards. This gives a better chance of lasting improvement because it removes the source of irritation rather than briefly masking its effects.

For a horse prone to ulcers, think of treatment as assembling several pieces of one puzzle. Herbs can be a helpful piece. Without diet and good management, the picture remains incomplete.

When herbs are not enough and a vet is needed

This is the most important part of the whole discussion. Herbs can support stomach comfort, but do not replace veterinary treatment. If your horse has active, painful lesions, plant-based additions alone will not solve the problem.

Warning signs

If you see any of the following signs, do not wait for the “blend to work”:

• Severe abdominal pain: your horse lies down, looks at their flanks or kicks at their belly.
• Marked lethargy: they stand listlessly, do not respond as usual and lose interest in their surroundings.
• Reduced appetite or refusal to eat: especially if they previously ate willingly.
• Weight loss or declining condition: even if the ration has theoretically not changed.
• Recurring discomfort during saddling or work: particularly if it appeared suddenly.

These signs may indicate a problem more serious than simple stomach irritation.

Limitations and contraindications

Not every herb suits every horse. I take particular care with:

• pregnant mares,
• horses taking medication,
• older animals and those with other diseases,
• horses with a history of strong reactions to new additions.

This applies especially to more “active” ingredients such as liquorice. These plants are particularly easy to overuse because you hear they are good “for the stomach” and give them for too long.

When herbs make sense, and when they do not

Herbs make sense when your horse has been diagnosed, treatment is in place and you want to support the lining and digestive comfort. They do not make sense as an emergency substitute for a vet when symptoms are severe, your horse is weakening or they are suffering.

The most sensible approach is simple. If your horse looks ill, call your vet first. Once a treatment plan is agreed, choose nutrition, feed and any herbs.

If you are planning nutrition for a horse with suspected or diagnosed ulcers and want to choose feed, chaff or a digestive support supplement, explore the VETfactory range. It provides a starting point for discussing practical feeding for a horse prone to ulcers, ideally alongside the advice of the vet treating your horse.
