VERMCLEAR *Organic herbal blend for horses - herbal-harmony, parasite-clearing, gut-rebalancing
VermClear is a synergistic blend of organic phytonutrients that supports a healthy intestinal environment, helping to naturally clear internal parasites and maintain digestive resilience.
Working in harmony with your horse’s natural defences, this aromatic and bitter blend of organic botanicals helps create an intestinal environment that discourages internal invaders, nurtures digestive health, and sustains inner equilibrium - the natural way.

Overview
The intestinal tract is at the heart of equine health - it’s not just where nutrients are absorbed, but also where much of the immune system is housed. When the gut environment becomes unbalanced, horses are more vulnerable to parasitic pressure, digestive discomfort, and reduced overall wellbeing.
VermClear is specifically designed to support the horse’s natural parasite-management mechanisms. Instead of acting like a chemical wormer that directly “kills” parasites, our organic herbal blend works by creating a gut environment where worms struggle to survive, attach, or complete their lifecycle.
VermClear works to ensure the gut remains balanced and functional by helping the intestinal microbiome stay stable and resilient, supporting the eradication of intestinal parasites naturally.
How natural worming works (and why herbs are different)
Parasites live through a repeating cycle of ingestion → migration → reproduction → egg shedding → larval development on pasture → reinfection. When this cycle is uninterrupted, worm pressure can rise quickly.
Anthelmintic herbs offer a long-used, natural alternative that helps break this cycle without the potential downsides sometimes associated with frequent chemical worming. Different herbs work in different, complementary ways:
- Vermicides – support the breakdown or paralysis of intestinal worms
- Vermifuges – help expel them through healthy bowel movement
- Taenicides – support the breakdown of tapeworms
- Taenifuges – help expel tapeworms, particularly where pumpkin seeds are involved
A well-designed natural blend also includes:
- A cathartic herb to keep the bowel moving and help clear larvae and eggs
- A demulcent to soothe any irritated gut tissue
- A synergist/stimulant herb to ensure the whole formula works in harmony
This combination is what allows natural worming to be effective while still being kind to the gut.
Why a natural approach?
There’s growing concern about chemical wormer resistance, with more parasites proving difficult to manage using conventional products alone. Some owners also prefer a softer approach due to potential side-effects of chemical wormers, which may include digestive upset or stress on the liver and microbiome.
Herbal support offers a tradition-based and research-backed approach that can sit alongside modern-day worm counts, strategic worming plans, and veterinary guidance.
What the research shows
Laboratory studies from the Institute of Organic Research in Switzerland demonstrated that certain anthelmintic herbs can produce:
- A 79% reduction in egg output by Day 5
- Complete cessation of egg hatch, meaning larvae fail to develop on pasture
This helps limit reinfection because larvae do not survive long enough to climb the grass and be ingested again - an important part of breaking the cycle.
How winter weather helps break the worm cycle
Nature lends a helping hand in parasite control, particularly as we move into late autumn.
A true hard frost – the kind that freezes the top layers of pasture – can significantly disrupt the lifecycle of many equine parasites. Once temperatures drop low enough, larval stages on the grass struggle to survive, which naturally reduces reinfection rates through winter.
Bots are a perfect example. Their larvae overwinter inside the horse’s gut, and because bot flies are long gone by November, a killing frost becomes an ideal time to support the clearing of these larvae. With no fresh eggs being laid and fewer larvae surviving on the pasture, the reinfection cycle is interrupted. Repeating this pattern each winter is even said to help reduce bot pressure across whole areas over time.
Worming programmes timed just after a killing frost – or in some regions just before one – may help keep horses relatively parasite-free until spring, especially when combined with regular faecal egg counts and good pasture hygiene.
A balanced gut environment and a well-functioning immune system also play a big role - see our BiomeTonic . When the intestinal environment is stable and robust, newly ingested larvae find it far harder to settle, attach, or complete their lifecycle.
This is where natural herbal blends and supportive feeds fit beautifully: they help keep the gut environment comfortable for the horse yet inhospitable for parasites.
In summary
VermClear supports the horse by:
- Helping maintain a gut environment that discourages parasites
- Aiding the natural expulsion of worms and larvae
- Supporting gut comfort, microbiome balance, and digestive resilience
- Working in harmony with regular worm counts and responsible pasture management

Composition & Feed Guide
VermClear is a nutritional, functional food supplement and not veterinary medicine. For more on this, see to Dr Kellon's article - Nutrition is not 'Alternative' Therapy .
Composition Glossary
Each herb in VermClear plays a targeted role in maintaining a healthy intestinal environment and supporting the body’s natural defences against internal parasites.
- Artemisia absinthium – Revered in traditional herbalism for its bitter principles ( absinthin and anabsinthin ) and aromatic oils, its natural bitters stimulate bile flow and digestive secretions, helping the gut remain inhospitable to parasitic organisms while toning the entire digestive system.
- Salvia officinalis – Rich in tannins and essential oils, its mildly astringent nature helps 'tighten' mucosal tissues and reduce stagnation, fostering a gut environment less favourable to parasite attachment.
- Thymus vulgaris – A classic cleansing herb containing thymol and carvacrol , compounds known for their aromatic and protective properties. Much valued for helping preserve microbial harmony and discourage internal parasitic imbalances.
- Zingiber officinale – A warming digestive stimulant that enhances circulation and bile flow, assisting the natural clearance of waste to maintain intestinal hygiene.
- Foeniculum vulgare – Soothes intestinal tension while encouraging efficient transit, with its carminative action helping expel gas and relieve discomfort that can accompany parasite irritation.
- Curcuma longa – Antioxidant and hepatic-supportive qualities, helps sustain liver function and gut wall integrity, promoting healthy bile metabolism and tissue resilience.
- Capsicum annuum – A circulatory stimulant containing capsaicinoids, which stimulate digestion. Traditionally viewed as a catalyst herb, Cayenne helps 'drive' the actions of companion botanicals while supporting a vigorous, self-cleansing gut terrain.
- Plantago ovata – A soluble-fibre source that gently bulks the intestinal contents, helping bind and remove waste products and debris, while its mucilage soothes the gut lining, assisting the natural expulsion of unwanted material.
- Inula helenium – Renowned in ethnoveterinary use for its mild anthelmintic actions. Its volatile oils and mucilage help calm pinworm-related irritation ( Oxyuris equi ), complementing the cleansing effect of the blend.

Fussy eater?
Horses sometimes have their own opinions (and strong tastebuds!), so now and then a new blend might need a little extra encouragement. This doesn’t reflect the quality or efficacy of the product, but rather their natural instinct towards new flavours.
Check out our Fussy Eaters page, or send us a message - we've many helpful tips to make introducing new supplements easier.
Recommended
Feed every 3-months following a faecal worm egg count (FWEC) if needed, or as a regular precautionary deterrent for ongoing intestinal protection.
- Spring and Summer (March-August) - Conduct regular FWECs, ideally every 12 weeks, to monitor worm levels as grazing continues.
- Autumn (September-November) - carry out a regular FWEC, and consider a saliva or blood test for tapeworm , as these are best treated in autumn before winter.
- Winter (December-February) - Encysted redworms develop in the gut wall and are not detected by FWECs, making a specific winter treatment crucial to prevent serious health problems colic and diarrhoea in the spring.

Advisory
- New to VermClear? Start slow, a pinch at a time, slowly building up to the RDA.
- Best fed following a regular faecal worm egg count (FWEC) programme.
- May have a mild cleansing or stimulating effect; adjust feeding time if the horse is sensitive.
- Avoid feeding at the same time as probiotics — separate by at least 4-hours to avoid neutralising beneficial bacteria.
Contraindications
- Not suitable for pregnant or nursing mares due to the aromatic and bitter nature of some herbs.
- Avoid concurrent use with anticoagulant or steroid medications unless under veterinary guidance.
- Not advised for horses with gastric ulcers or intestinal inflammation due to the stimulating bitters and spices.
