Homoeopathy as its name proclaims is the science of “like sickness”, because its medicines are used to cure only the exact conditions they can produce in healthy human beings. Homoeopathy is the medicine of vital stimulation, that refers to its aim, which is not physiological action, but vital reaction. Nosodes comprise dilutions of pathogenic organs or tissues; causative agents such as bacteria, fungi, ova, parasites, virus particles and yeast; disease products; and excretions or secretions. Nosodes are considered as homoeopathic medicines, if processed in accordance with a recognized homoeopathic pharmacopoeia in official use, or other officially recognized documents. Nosodes though neglected but when used have proven to produce excellent results. Nosodes is a very vast subject to study in homoeopathy, till now more than 60 nosodes have been introduced in the homoeopathic field. Many new nosodes are also being added to the armamentarium of our Materia Medica. Through this course we will study a good number of nosodes including the newest ones, in the best possible aspects.
