The classic milk remedies Lac caninum and Lac felinum have been firm fixtures in homeopathy since the nineteenth century. Their remedy pictures are typical of domesticated mammals. In recent times, homeopathic interest has been directed to their wild cousins. The milks of most of the big cats such as the lynx, cheetah, ocelot, tiger, lion, and jaguar have already been potentized. And for the wild dogs we already have fox, jackal, and wolf milk. The focus of this issue is the special homeopathic characteristics of these new remedy groups of the carnivorous mammals and the differentiation of the individual remedies in the families Canidae and Felidae. It is especially exciting to differentiate the wild animals of prey from their domesticated cousins with the help of remedy provings and case histories. This issue of Spectrum thus breaks new ground in the evolution of the modern materia medica – never before has this topic been presented as a whole.
