Å’nothera biennis. Large Evening Primrose. Tree Primrose. (North America.) N. O. Onagraceae. Tincture of fresh plant.

Clinical.-Cholera infantum. Diarrhoea. Hydrocephaloid.

Characteristics.-There is a proving recorded by T. Riker Nute on a woman who took on two occasions-(1) a teaspoonful, (2) 30 drops of the liquid extract for the relief of a wearisome feeling of mental and physical oppression, and on each occasion, notably the first, distinct poisoning symptoms were developed. A kind of general paralysis of mental and bodily forces was induced, and at the same time copious and easy evacuations of bowels and bladder, followed by relief of the general symptoms. It is in effortless diarrhoea that Å’noth. has been most successfully used in homoeopathic practice. Farrington gives the indications: Exhausting, watery diarrhoea without effort; with nervous exhaustion; even incipient hydrocephaloid. Hurd (H. R., x. 419) cured a man, 65, who had "severe pains in his stomach after meals for over two years" with 25-drop doses of the tincture. General numbness; general warm sweat with urgent desire to micturate; > after evacuation of bowels and bladder, are noteworthy symptoms.
