Cushing's Disease: a new approach to therapy in
1Kingley Veterinary Centre, Oldwick Farm, West Stoke Road, Lavant, West Sussex, PO18 9AA, UK
Forty-one cases of Cushing's Disease affecting both equine and canine patients were
treated with an identical mixture of two homeopathically prepared remedies (ACTH 30c
and Quercus robur 30c), and the clinical improvements seen in the cases assessed.
Homeopathy has been described as a medicine that can only be prescribed on the basis
of individual symptoms shown, ®tting the remedy to the patient, not the disease. The
aim of this study was to de®ne whether a standardised approach, using homeopathi-
cally prepared remedies, was a valid system of therapy for this disease, and if so,
whether results were repeatable between species. The overall success rate for the
therapy was 80% and results were broadly similar between the two species, indicating
that homeopathy lends itself to the treatment of Cushing's Disease, and also to both
cohort studies and group medicine. British Homeopathic Journal (2001) 90, 33±36.
