World Wildlife Day is a UN International day created to celebrate the beauty and diversity of all wild plants and animals and the contribution they make to our well-being.1

An over-looked area of homeopathic research is the ongoing work by scientists exploring the role homeopathy may be able to play in wildlife veterinary medicine.

A growing number of clinical studies have shown benefits of homeopathic treatment in Magellanic penguins, cared for in a zoological park in Brazil. Homeopathic medicines have been used to treat important clinical complications which commonly occur in penguins living in such an environment, including:

  • altered liver enzymes2
  • pododermatitis – a potentially life-threatening infection of the feet3
  • immunological stress during reproduction4, and
  • elevated plasma uric acid levels related to abnormal kidney function5.

As randomised clinical trials are clearly not feasible on most wild animals, high quality case studies are considered the best method for documenting individual experiences and assessing the potential benefit of homeopathy in treating wildlife. They present verifiable, objective details and are able to formally assess the likelihood of a link between treatment and outcome6, making their findings a valuable part of the veterinary evidence base.

For example, a recent high quality case study has shown the beneficial impact of homeopathic treatment for stalled folliculogenesis (decreased reproductive function) in two ball pythons.7

Homeopathic wildlife veterinarians in Brazil have also successfully treated:

  • Burmese pythons and a boa constrictor with pneumonia8,
  • two baby possums with hookworm infections in the gut9,
  • a puma with dysregulated estrus cycle10,
  • a maned wolf with suspected osteomyelitis after being hit by a car11,
  • a raccoon with antibiotic resistant osteomyelitis12, and
  • a sea turtle suffering from multiple tumours (fibropapillomatosis) including a growth on the cornea of the eye13.

Veterinary case studies for wildlife involve rescued animals, those injured through human activity, or those cared for by veterinarians in zoological parks. They provide a useful first step in exploring how homeopathy may be able to support the health and well-being of these animals.

It is encouraging to see the growing trend in homeopathy research towards the use of the latest high quality case reporting methods,14 following agreed reporting guidelines15, in both animals and humans, enabling individual experiences of homeopathic treatment in all species to be turned into meaningful ‘real world’ evidence.

HRI is a UK-based charity dedicated to promoting high quality research in homeopathy at an international level.
