Any plant, mineral or animal substance can be used as a remedy. The original substance is diluted in liquid repeatedly, and vigorously shaken with each dilution. Unusual as it sounds, these very small amounts of remedies can act very strongly when used properly. Also, because the remedies are very diluted, they are extremely safe. The clinical experience of homeopathy shows that the micro-dose is effective: It works upon comatose people, infants and animals.
