Uses : It is widely used as a nutritious Bird feed. Gastric, or intestinal cramps, diarhhoea, neuralgia, cough hysteria, manis, skin inflammation and boils. Niger seeds has anodyne, narcotic and mydriatic properties, employed as a sedative in nervous infections. In veterinary practice used as urnary sedative.

It is poisonous in all its parts, and neither drying nor boiling destroys the toxic principle. The leaves are the most powerful portion, even the odour of them when fresh will produce giddiness and stupor. Accidental cases of poisoning by Henbane are, however, not very common, as the plant has too unpleasant a taste and smell to be readily mistaken for any esculent vegetable, but its roots, which are thick and somewhat like those of salsafy, have sometimes been gathered and eaten. In one case recorded, a woman pulled up a quantity of Henbane roots which she found in a field, supposing them to be parsnips. She boiled them in soup, which was eaten by the family. The whole of the nine persons who had partaken of them suffered severely, being soon seized with indistinctness of vision, giddiness and sleepiness, followed by delirium and convulsions.


HYOSCYAMUS NIGER. Powerful cerebral and spinal sedative used since remote ages to induce sleep and allay pains. Often an ingredient in witches' brews for its power of throwing victims into convulsions.

Medicinal Action and Uses---Antispasmodic, hypnotic, mild diuretic. The leaves have long been employed as a narcoticmedicine. It is similar in action to belladonna and stramonium, though milder in its effects.

The drug combines the therapeutic actions of its two alkaloids, Hyoscyamine and Hyoscine. Because of the presence of the former, it tends to check secretion and to relax spasms of the involuntary muscles, while through the narcotic effects of its hyoscine it lessens pain and exercises a slight somnifacient action.

Its most important use is in relief of painful spasmodic affections of the unstriped muscles, as in lead colic and irritable bladder. It will also relieve pain in cystitis.

It is much employed to allay nervous irritation, in various forms of hysteria or irritable cough, the tincture or juice prepared from the bruised, fresh leaves and tops being given in mixtures as an antispasmodic in asthma.

Combined with silver nitrate, it is especially useful in the treatment of gastric ulcer and chronic gastric catarrh.

It is used to relieve the griping caused by drastic purgatives, and is a common ingredient of aperient pills, especially those containing aloes and colocynth.

In small repeated doses Henbane has been found to have a tranquillizing effect upon persons affected by severe nervous irritability, producing a tendency to sleep, not followed by the disorder of the digestive organs and headache, which too frequently result from the administration of repeated doses of opium, to which Henbane is often preferred when an anodyne or sedative is required. The comparatively small amount of atropine present does not give rise to the excitation and delirium occasioned by belladonna. It is, therefore, used in insomnia, especially when opium cannot be given. Except for this, it acts like atropine.

A watery solution of the extract applied to the eye has a similar effect to that of atropine, in dilating the pupil and thus preparing the eye for an operation, or assisting the cure of its internal inflammation. This dilution leaves no injurious effect afterwards.

In the form of extract or tincture, it is a valuable remedy, either as an anodyne, a hypnotic or a sedative, and will take effect when other drugs fail. When used for such a purpose, it is the active principle, Hyoscine, that is employed. This is very powerful - only a very small amount is used, from 1/200 to 1/70 of a grain of the Hydrobromate of Hyoscine. This drug comes under Table I of the Poisons Schedule. In poisonous doses Henbane in any form causes dimness of sight, faintness, delirium, and sometimes death.
