Homeopathic remedies work for animals and therefore they cannot be placebos!!!
This argument is the standard reply of believers in homeopathy (not least of Prince Charles). It shows, I think, two things:
- Believers in homeopathy fail to understand the placebo effect.
- They are ill-informed or lying about the evidence regarding homeopathy in animals.
As we have explained on this blog over and over again: the evidence for homeopathy in animals is very much like that in humans: it fails to show that highly diluted homeopathic remedies are more than placebos (see, for instance here, here and here). Now a further study confirms this fact.
The objective of this triple-blind, randomized controlled trial was to assess the efficacy of homeopathic treatment in bovine clinical mastitis. The study was conducted on a conventionally managed dairy farm between June 2013 and May 2014. Dairy cows with acute mastitis were randomly allocated to homeopathy (n = 70) or placebo (n = 92), for a total of 162 animals. The homeopathic treatment was selected based on clinical symptoms but most commonly consisted of a combination of nosodes with Streptococcinum, Staphylococcinum, Pyrogenium, and Escherichia coli at a potency of 200c. Treatment was administered to cows in the homeopathy group at least once per day for an average of 5 d. The cows in the placebo group were treated similarly, using a placebo preparation instead (lactose globules without active ingredients). If necessary, the researchers also used allopathic drugs (e.g., antibiotics, udder creams, and anti-inflammatory drugs) in both groups. They recorded data relating to the clinical signs of mastitis, treatment, time to recovery, milk yield, somatic cell count at first milk recording after mastitis, and culling. Cows were observed for up to 200 d after clinical recovery. Base-level data did not differ between the homeopathy and placebo groups. Mastitis lasted for an average of 6 d in both groups. No significant differences were noted in time to recovery, somatic cell count, risk of clinical cure within 14 d after disease occurrence, mastitis recurrence risk, or culling risk.
The authors concluded that the results indicated no additional effect of homeopathic treatment compared with placebo.
The question is HOW MUCH MORE EVIDENCE IS NEEDED BEFORE HOMEOPATHS ABANDON THEIR BOGUS CLAIM?
