The Research Evidence for Homeopathy

There have been many research studies looking at the effectiveness of homeopathy in the treatment of animal diseases.

Here we will summarize just a few.

In the largest-ever study of dogs and cats1, a 2010 Clinical Outcomes survey identified many clinical conditions where homeopathy showed real promise – warranting still further research.

In this study, 21 homeopathic veterinary surgeons in the United Kingdom recorded data from their patients over 12 months and collected information from a total of 1,500 dogs and 400 cats. By owners’ assessments, moderate or major improvement was reported overall for 68% of dogs and 63% of cats.

Data from 400 cats comprised a total of 372 individual chronic problems, of which 270 had a follow-up assessment. Data from 1,504 dogs comprised a total of 1,408 individual chronic problems, of which 1,070 had a follow-up assessment. In both species, 22% of the follow-ups in chronic cases received conventional medicines concurrently.

In cats, 117 different chronic medical conditions in total were treated with homeopathy. Five of those conditions included 20 or more cases, in which owner-reported outcomes (in decreasing rank order of frequency) were as follows:

Chronic Condition
in Cats
Favorable Outcome
(% patients)
Unfavorable Outcome
(% patients)
Dermatitis 69.6% 0%
Renal Failure 57.1% 14.3%
Overgrooming 57.1% 7.2%
Arthritis 80% 0%
Hyperthyroidism 66.7% 0%
In dogs, of 301 different chronic medical conditions treated in total, those most commonly recorded (20 or more cases) were:
Chronic Condition
in Dogs
Favorable Outcome
(% patients)
Unfavorable Outcomes
(% patients)
Dermatitis 66.2% 5.4%
Arthritis 80.2% 0.8%
Pyoderma 75.8% 0%
Colitis 85.2% 0%
Fear 31.6% 0%
Epilepsy 63.6% 4.5%
Otitis externa 72.7% 0%
Diarrhoea 68.2% 0%
Urinary incontinence 73.7% 0%
Aggression 57.1% 0%
Spondylosis 81% 0%
Lymphoma 40% 6.7%

What about farm animals?

There’s a growing volume of research here as well and much of it centers on the care of cows and pigs which are the two major categories in commercial animal farming.

An example of that research is work that’s been done to reduce the need for antibiotics in the treatment of mastitis in cows (infected udders).

In one German study2, researchers examined the effectiveness of classical homeopathic treatment in cases of mild and moderate bovine clinical mastitis in comparison with antibiotic and placebo treatments.

A total of 136 lactating dairy cows with 147 affected quarters from four herds in Germany were randomly allocated to three treatment groups.

Their findings? In cases of pathogen-positive mastitis, the cure rate after four and eight weeks was similar between the two treatment strategies, homeopathy and antibiotic treatment, but the difference between the homeopathic and the placebo treatment at day 56 was significant. According to the study authors, these results indicate a therapeutic effect of homeopathic treatment in cases of mild and moderate clinical mastitis.
