Several homeopathic drugs are prepared from the animal kingdom which are prepared in the similar manner as that of the plant kingdom the only difference being here the part of the whole animal is taken to prepare the medicine. A few examples of drugs are, Latrodectus mactans, Tarentula hispania (Spanish spider), Tarentula cubensis (Cuban spider), Naja tripudians (King Cobra), Vipera (Russell’s viper), Sepia (Dried inky juice of cuttle fish), Cantharis (Spanish fly).
The drugs under this category are very useful and have a good medicinal effect. Individual drugs or compounds are taken and medicines are prepared. It also contains elements such as Phosphorous. A few examples are Calcarea carbonica (Calcium carbonate–CaCo3), Phosphorus (Phosphorus), Calcarea phosphorica (Calcium phosphate–Ca3 (PO4)2), Natrum muriaticum (Sodium chloride–NaCl). Acids are also included in this category such as Nitric acid (Nitricum acidum), Phosphoric acid (Acidum phosphoricum), etc. Also metals are included in this category such as Copper (Cuprum metallicum), Iron (Ferrum metallicum), Gold (Aurum metallicum) and Silver (Argentum metallicum). These metals are potentized with Saccharum Lacts (Lactose sugar) a procedure which minimizes the toxicity of the metals and lower concentration that is higher potencies are prepared where the medicinal powers of these metals are obtained.
These are drugs prepared from morbid parts or secretions of animals. The extract is similarly diluted to remove the toxicity of the drug and thereon with further succussions higher potencies are produced. A few examples of these are, Anthracinum (Diseased spleen of sheep), Medorrhinum (Morbid Grease of horse).
These are drugs prepared from healthy parts or secretions of animals. E.g Pancreatin (secretion of the pancreas). Higher potencies are efficacious in treatment of various disorders.
This is a very important and unique feature of Homeopathy. Drugs are actually prepared from universal energies. That is for example, Alcohol is exposed to X–rays to have a drug called X–ray. Drugs are even prepared from Moon rays.
