Spirulina (Arthrospira platensis / Arthrospira maxima)

Botanical Name: Arthrospira platensis, Arthrospira maxima
Common Name: Spirulina
Family: Oscillatoriaceae
Classification: Cyanobacteria (blue-green algae)

Description

Spirulina is a filamentous, spiral-shaped blue-green algae that grows in alkaline, mineral-rich waters, both in natural lakes and cultivated ponds. It thrives in tropical and subtropical climates and is one of the oldest life forms on Earth, forming an important part of traditional diets in regions such as Africa and Central America.

The algae’s vibrant blue-green hue comes from its high chlorophyll and phycocyanin content. It has a slightly fishy, umami taste and is harvested, dried, and powdered for its rich nutritional profile.

Parts Used
  1. Whole Algal Biomass: The entire spirulina organism is used. After harvesting, it is usually dried and powdered for use in capsules, tablets, or added directly to food and drinks. There are no "separate parts" in the traditional herbal sense, as the entire biomass is considered medicinal and nutritional.
Therapeutic Properties
  • Antioxidant: Rich in phycocyanin and chlorophyll, spirulina helps combat oxidative stress and supports cellular health.
  • Nutrient-Dense: Contains high levels of complete protein (up to 70%), B vitamins (especially B12 analogs), iron, magnesium, beta-carotene, and essential fatty acids.
  • Immunomodulatory: Spirulina supports the immune system by enhancing antibody production and modulating inflammation.
  • Detoxifying: Assists in heavy metal chelation and liver support.
  • Energy Boosting: Known for improving stamina and reducing fatigue due to its high protein and iron content.
  • Anti-inflammatory: Helps reduce systemic inflammation, useful in joint and autoimmune conditions.

Equine Use

Spirulina is increasingly popular as a nutritional supplement for horses, especially those needing immune support, improved respiratory health, or additional protein and micronutrients.

- Administration: Typically given in powdered form, either top-dressed on feed or mixed into wet feed (e.g., soaked beet pulp or mash).
- Uses:
  • Supports horses with allergies or respiratory issues (e.g., COPD/RAO).
  • Enhances muscle recovery and stamina in performance horses.
  • Provides additional nutrition for underweight or stressed horses.
  • Helps horses on restricted pasture due to metabolic conditions (e.g., EMS, laminitis).
Note: Spirulina has a strong taste and odor; horses may need time to adapt.

Canine Use

Spirulina is well-tolerated by dogs and is often used for general health maintenance, immune support, and skin and coat health.

- Administration: Given as a powder mixed into food, or in capsule/tablet form.
- Uses:
  • Enhances immune response, particularly helpful in senior dogs or dogs recovering from illness.
  • Improves coat shine and reduces skin irritation/allergies.
  • Aids detoxification after vaccination or medication.
  • Supports overall vitality and energy, especially in active breeds.
⚠ Caution: Ensure spirulina is sourced from clean, reputable suppliers to avoid contamination with heavy metals or toxins.

Folklore and Mythology in the UK and Isle of Man

While spirulina itself is not native to the British Isles and doesn’t have ancient folklore in the way native herbs do, its modern introduction has inspired a new wave of “eco-folklore” and symbolic resonance, particularly in the realms of health, longevity, and connection to nature.

  1. The "Green Dragon’s Breath": In Manx contemporary folklore, spirulina is sometimes humorously referred to as "Green Dragon’s Breath" — a nod to its deep green-blue color and its supposed power to invigorate life and vitality. In local storytelling, it’s imagined as a substance gifted by ancient sea-dragons to heal the land and the people.

  2. Modern Sea-Wisdom: Among herbalists in the UK and on the Isle of Man, spirulina is increasingly considered part of the “new sea wisdom” — a class of marine botanicals believed to help humans reconnect with the Earth’s original waters and primordial energy. It's seen as a bridge between ancient life and modern healing.

  3. Ritual and Symbolism: Some contemporary practitioners in the British Isles use spirulina in ritual teas or “green potions” during seasonal transitions — particularly in spring (Imbolc/Beltaine) as a symbol of renewal, cleansing, and energy. It's also associated with Virgo and Aquarius in astro-herbal traditions, connecting it to clarity, cleansing, and transformation.

Conclusion

Spirulina (Arthrospira spp.) is a potent, nutrient-dense blue-green algae with remarkable health benefits for both animals and humans. It supports energy, immune function, detoxification, and vitality. In horses and dogs, it serves as a gentle yet powerful supplement for nutritional and systemic support.

While spirulina lacks ancient UK and Manx herbal lore, it is quickly becoming a respected addition to modern natural health traditions, taking on new folkloric significance as a marine ally in times of physical and environmental transformation.

As always, consult with a holistic vet, herbalist, or healthcare practitioner before introducing new supplements to your or your animal’s routine.
