Whole Herbs, Real Benefits
Echinacea Root & Herb (Echinacea purpurea)
Echinacea root and herb support normal immune function. These two parts of the plant bring its traditional herbal role into formulas designed to support a pet’s natural defenses.
Echinacea Root & Herb (Echinacea purpurea)
Oregon Grape (Mahonia aquifolium)
Oregon grape root supports the body’s innate immune response and mucosal membranes. It is the sole active herb in Oregon Grape Herbal Tonic and one component of Resist & Renew. Follow each formula’s own directions and use guidance.

Alfalfa (Medicago sativa)
Alfalfa brings a naturally nutrient-containing herb to the blend. Its role complements the other botanicals without making this small serving a replacement for a complete, balanced diet.
Alfalfa (Medicago sativa)
Garlic (Allium sativum)
Garlic is used as one component of these measured herbal blends. Appropriate amounts and the pet’s health matter: excessive, sustained use may cause Heinz body anemia, and formulas containing garlic may carry surgery and anemia precautions.
Garlic (Allium sativum)
Spirulina (Arthrospira platensis)
Spirulina is a blue-green microalga with naturally occurring pigments and nutrients. It complements the herbal blend; the formula is a wellness supplement, not a replacement for balanced nutrition.
