BiomeTonic Veterinary Reference Extract
EquiNatural® Botanical Nutritional Support for Intestinal Microbial Balance & Daily Digestive Resilience
Organically grown • Human grade • Not veterinary medicine
1. Important Context for Veterinary Review
Hindgut microbial fluctuations in horses are influenced by:
- rapid dietary or grass changes
- stress or autonomic imbalance
- acidotic fermentation patterns
- forage inconsistency (haylage, drought-stressed grass, high-ESC hay)
- antibiotic or NSAID exposure
- subclinical dysbiosis or parasitic pressure
- low-diversity diets lacking phytochemical intake
Clinical signs of early hindgut disturbance often appear behaviourally before they appear diagnostically:
- girthiness, flinching, belly sensitivity
- right-hind swish or irritability on grooming
- grass-related “gut wobbles”
- variable manure form, mild gas, or transient discomfort
These presentations are multifactorial and cannot be attributed to any single feed or supplement. BiomeTonic provides nutritional, aromatic-herbal support only, and should be introduced gradually.
Functional Positioning — BiomeTonic
BiomeTonic is designed for Phase 3: Microbial Maintenance & Terrain Stability within EquiNatural’s gut-support continuum.
- Phase 1 — Dysbiosis Correction: SiboCARE
- Phase 2 — Faecal Water/Mucosal Rehabilitation: LeakyGutCOMBO / GutAminos
- Phase 3 — Microbial Maintenance: BiomeTonic
BiomeTonic does not correct active dysbiosis. Instead, it maintains microbial balance once stability is achieved, using time-honoured aromatic oily botanicals to discourage pathogenic overgrowth while supporting calm, resilient gut terrain. It is the proactive/preventative “keep things steady” formula — ideal for horses who flare with stress, grass change, or seasonal gut shifts.
It is not:
- a mucosal-repair formula
- a high-fibre prebiotic
- a gastric ulcer blend
- appropriate during active gut pain, diarrhoea, fever, or acute dysbiosis
BiomeTonic forms the nutritional bridge between resolution and resilience in long-term gut health.
Core Actions
- Supports a balanced microbial terrain via aromatic antimicrobial phytochemicals
- Helps discourage bacterial, fungal, protozoal overgrowth
- Aids digestive tone and motility without forcing catharsis
- Provides buffering/calming support to the mucosa
- Contributes to gut–liver axis steadiness
- Helps reduce belly reactivity (girthiness, swishiness, tension) during environmental change
Rationale for Key Components
Origanum vulgare (Carvacrol & Thymol–rich)
Aromatic antimicrobial herb supporting microbial population control and discouraging pathogen adherence.
Thymus vulgaris
Warming digestive aromatic improving motility, microbial harmony, and intestinal tone.
Salvia officinalis
Astringent, phenolic-rich botanical stabilising the microbial terrain and supporting mucosal integrity.
Salvia rosmarinus (Rosemary)
Antioxidant, hepatoprotective, and gut–liver axis supportive; enhances resilience under oxidative or metabolic load.
Tabebuia impetiginosa (Pau d’Arco)
Naphthoquinone-rich inner bark historically used for fungal and microbial regulation.
Matricaria recutita (Chamomile)
Buffers stronger aromatics; soothes mucosa, eases tension, and supports digestive comfort.
2. Product Summary
BiomeTonic is an aromatic botanical blend formulated to support:
- daily microbial equilibrium
- stable hindgut comfort
- improved tolerance to forage or grass change
- behavioural indicators of gut tension (girthiness, flank-sensitivity)
- post-dysbiosis maintenance following SiboCARE or LeakyGutCOMBO
It is a nutritional maintenance support, not a dysbiosis-correction formula.
3. Clinical Rationale (Nutritional Mechanisms of Action)
Aromatic Antimicrobial Activity
Volatile oils (carvacrol, thymol, rosmarinic acid) help balance microbial populations without sterilising the hindgut environment.
Microbial Terrain Support
Astringent and phenolic botanicals help discourage pathogens while preserving commensal diversity.
Mucosal Comfort & Buffering
Chamomile’s sesquiterpenes and mucilage help maintain epithelial ease and reduce tension.
Gut–Liver Axis
Rosemary and Pau d’Arco support oxidative resilience and metabolic clearance of microbial metabolites.
Motility & Digestive Tone
Thyme and oregano support normal motility and reduce stagnation-associated dysbiosis patterns.
Nutritional aromatics do not treat infection, but support a balanced and comfortable gut terrain.
4. Nutritional Indications (Non-Diagnostic)
BiomeTonic may be considered nutritionally for horses showing:
- mild to moderate belly sensitivity
- girthiness or right-hind swishiness
- seasonal or stress-related microbial instability
- grass-related “gut wobbles”
- post-antibiotic or post-dysbiosis recovery (maintenance phase)
- sensitivity to haylage transitions or rich grass
Not indicated for:
- acute diarrhoea
- fever
- severe abdominal pain/colic
- active SIBO-pattern dysbiosis (→ use SiboCARE first)
- faecal water with mucosal fragility (→ LeakyGutCOMBO)
5. Composition (Organically Grown)
Botanical Composition
- Matricaria recutita
- Origanum vulgare
- Tabebuia impetiginosa
- Salvia rosmarinus
- Salvia officinalis
- Thymus vulgaris
Botanical Safety Preface
Aromatic herbs require appropriate dosing. Individual tolerance varies depending on forage quality, microbial stability, stress load, and underlying gut condition.
6. Herb Micro-Monographs
Matricaria recutita
Mucosal buffer, mild antispasmodic, and anti-inflammatory support.
Origanum vulgare
Carvacrol-rich aromatic supporting microbial equilibrium.
Tabebuia impetiginosa
Traditional botanical supporting microbial balance and internal resilience.
Salvia rosmarinus
Antioxidant and hepatic-supportive herb aiding gut–liver metabolic clarity.
Salvia officinalis
Astringent stabiliser of microbial terrain and epithelial tone.
Thymus vulgaris
Highly aromatic herb supporting motility, immune–microbial interface, and digestive ease.
7. Medication Considerations
Veterinary oversight advised when fed alongside:
- Anticoagulants — some aromatics possess mild circulatory effects
- Steroids or immunosuppressants — immune-modulating botanicals may alter responsiveness
- Proton pump inhibitors or antacids — space feeds 2–3 hours apart
- Drugs metabolised via hepatic CYP pathways — rosemary and sage have mild influence on detox enzymes
No adverse interactions documented at nutritional levels when used appropriately.
8. Feeding Guidance
Dried Herb Blend
5 g per 100 kg bodyweight daily
(25 g for a 500 kg horse)
1 level 75 ml scoop ≈ 16 g
Introduction
Introduce gradually over 4–7 days.
Sensitivity Advisory
Discontinue if unexpected digestive discomfort occurs.
9. Clinical Considerations
Advisories
- Feed only once acute dysbiosis or gut pain has stabilised.
- Ideal as alternate-day or daily microbial maintenance.
- Ensure 24/7 access to long-stem fibre, salt, and water.
- Works synergistically after SiboCARE (Phase 1) and LeakyGutCOMBO (Phase 2).
Contraindications
- Pregnancy / lactation (due to aromatic uterine-tonic herbs).
- Active gastric ulceration or acute abdominal pain.
- Horses on anticoagulant medication unless supervised.
- Not for use during febrile illness or active infection.
