Homeopathic medicines are prepared from the following 6 major sources :
Plant kingdom: About 60% of the homeopathic medicines are prepared from one or more parts of plants. The whole plant or some parts
of it, such as leaves, roots, flowers, seeds, and berries, may be used in the preparation of the medicines. All types of plants, benign, poisonous,
and carnivorous, have been used as homeopathic medicines.
Common plant-based homeopathic medicines are Pulsatilla nigra, Bryonia alba, Aconite napellus, Belladona, Gelsemium, Coffea cruda, Rhus
Toxicodendron, etc.
Mineral kingdom: Approximately 20% of the homeopathic medicines are prepared from minerals, including metals, non-metals,
and their compounds. Some of the medicines prepared using minerals are Aurum metallicum (gold), Kali carbonicum (potassium), Natrum muriaticum
(common salt), and Silica (sand). The therapeutic
properties of almost all known metals and non-metals and many important compounds have been exploited in homeopathy.
Animal kingdom: Some homeopathic medicines are derived from certain animal products, which are obtained without killing
animals. Animal products, such as snake poison, spider poison, etc., are used in extremely minute doses to prepare homeopathic medicines.
Examples include Tarantula hispania, Lachesis, Ambra gresia, Bufo rana, and Naja naja.
Diseased tissues: Some homeopathic medicines are prepared using tissues or secretions containing bacteria, viruses,
and other microorganisms. Thus, homeopathy advocated the therapeutic use of minuscule amounts of microorganisms long before the
introduction of vaccines. Some commonly used
homeopathic medicines prepared in this manner include Tuberculinum, Syphillinum, and Variolinum.
Hormones and healthy tissues: Healthy human/animal tissues and secretions are also used to prepare homeopathic medicines.
Examples of such medicines are Thyroidinum and Adrenaline.
Imponderables: Certain energy sources, such as magnetism, x-ray, radiation, etc., are also used to prepare homeopathic medicines.
