Functional mushrooms are emerging as important adjunctive tools in integrative veterinary medicine, offering research-aligned support for immune balance, gastrointestinal integrity, neurological resilience, metabolic stability and healthy ageing in companion animals. Veterinary Mycotherapy: Medicinal Mushrooms for Advanced Integrative Clinical Practice provides clinicians with a clear, structured and evidence-informed foundation for incorporating full-spectrum mushroom extracts into veterinary care.

Drawing on global scientific literature, traditional Mycotherapy principles and insights from integrative veterinarians, this guide explains how fruiting-body mushrooms exert multi-system physiological actions that extend far beyond isolated β-glucans. It examines immune modulation, inflammatory balance, antioxidant defence, cognitive support, metabolic and endocrine harmony, gastrointestinal function and general vitality across dogs, cats and horses. The book also highlights the critical role of extract integrity in clinical decision-making, offering a tiered-based framework and practical guidance for selecting mushrooms as adjunctive support.

A central feature of the text is its exploration of Sub-critical Water Extraction (SCWE), a solvent-free method that preserves the complete biochemical matrix of the mushroom, including β-glucans, triterpenes, ergothioneine, phenolics, sterols, peptides and natural prebiotic fibres, without grain fillers or carriers. This whole-food approach aligns with functional nutrition and provides veterinarians with a reliable extract suitable for integrative practice.

The guide examines eight key functional species widely used in veterinary support: Reishi, Turkey Tail, Lion’s Mane, Chaga, Cordyceps, Maitake, Shiitake and OMG Mushrooms’ signature ergothioneine-rich Golden Oyster. Each species is presented through a clinically structured format that includes a concise veterinary brief, extended evidence summary, physiological mechanisms, species-specific considerations, pharmacological notes, safety insights and practical selection checklists. Additional discussions cover whole-food versus myceliated-grain products, ergothioneine and healthy ageing, and emerging applications of functional mushrooms for dogs and other animals.

Designed for integrative veterinarians, allied practitioners, animal naturopaths, students of holistic animal health and dedicated pet guardians, this book provides a balanced and responsible overview of veterinary Mycotherapy. It emphasises evidence, safety, extraction integrity and high-quality sourcing while offering practical guidance that bridges research with real-world clinical application.

As interest in functional mushrooms grows worldwide, the need for transparent, scientifically grounded information has never been greater. Veterinary Mycotherapy offers an accessible and dependable reference for those seeking to understand how full-spectrum, fruiting-body mushroom extracts may complement contemporary veterinary medicine and support the long-term wellbeing of companion animals.
