There are some recent reports about a case where a homeopath treated a child with what they claimed is a homeopathic medicine based on saliva from a rabid dog (lyssinum).
Homeopath and naturopath Anke Zimmermann used diluted saliva from a rabid dog to “treat” a four-year-old boy, according to a blog post she published earlier this year. Zimmermann claims that the potentially infectious and deadly concoction successfully resolved the boy’s aggressive behavior, which she described as a “slightly rabid-dog state.”
Ars Technica: Health experts aghast after homeopath gives kid rabid-dog saliva
Now, the homeopath clearly claims that they treated the boy with this, but what I find quite hard to believe is that the homeopathic preparation is actually based on saliva from a rabid dog. Rabies is a deadly disease, getting a saliva sample from a rabid dog seems difficult enough already, but then also handling it without endangering yourself to create the hopefully harmless final dilutions seems quite difficult.
Is there any evidence that lyssinum is actually based on diluted saliva from a rabid dog?
