Hahnemann’s proving symptoms of homeopathy remedy Hyoscyamus Niger from Materia Medica Pura, which Samuel Hahnemann wrote between 1811 to 1821…


(The expressed juice of the fresh plant, Hyoscyamus niger, mixed with equal parts of alcohol.)

When dried the plant loses a great portion of its medicinal powers.

The following symptoms, which were produced by this drug on healthy persons, show the mental and emotional disorders and the derangement of the senses in which it is of use.

A dose containing a quadrillionth of a drop of the juice, or better, a small portion of such a drop is more than sufficient for all homoeopathic curative purpose when all other foreign irritants and drugs are kept away from the patient.

Frequent smelling at a saturated solution of camphor removes the troublesome effects of hyoscyamus when it has been given in too large a dose of in an unhomoeopathic case.

Although the symptoms of this plant recorded below are very numerous, they require to be added to in order to make them complete.

Samuel Hahnemann
Samuel Hahnemann (1755-1843) was the founder of Homoeopathy. He is called the Father of Experimental Pharmacology because he was the first physician to prepare medicines in a specialized way; proving them on healthy human beings, to determine how the medicines acted to cure diseases.

Hahnemann's three major publications chart the development of homeopathy. In the Organon of Medicine, we see the fundamentals laid out. Materia Medica Pura records the exact symptoms of the remedy provings. In his book, The Chronic Diseases, Their Peculiar Nature and Their Homoeopathic Cure, he showed us how natural diseases become chronic in nature when suppressed by improper treatment.
