[448] It gets its name from the Latin primus, first, being named in old books and M.S. Pryme rolles, and in the Grete Herball, Primet, as shortened from Primprint.
In North Devon it is styled the Butter Rose, and in the Eastern counties it is named (in common with the Cowslip) Paigle, Peagle, Pegyll, and Palsy plant.
Medicinally also it possesses similar curative attributes, though in a lesser degree, to those of the Cowslip. Both the root and the flowers contain a volatile oil, and "primulin" which is identical with mannite: whilst the acrid principle is "saponin." Alfred Austin, Poet Laureate, teaches to "make healing salve with early Primroses."
Pliny speaks of the Primrose as almost a panacea: In aquâ potam omnibus morbis mederi tradunt. An infusion of the flowers has been always thought excellent against nervous disorders of the hysterical sort. It should be made with from five to ten parts of the petals to one hundred of water. "Primrose tea" says Gerard, "drunk in the month of May, is famous for curing the phrensie."
The whole plant is sedative and antispasmodic, being of service by its preparations to relieve sleeplessness, nervous headache, and muscular rheumatism. The juice if sniffed up into the nostrils will provoke violent sneezing, and will induce a free flow of water from the lining membranes of the nostrils for the mitigation of passive headaches: though this should not be tried by a person of full habit with a determination of blood to the head. A teaspoonful of powdered dry Primrose root will act as an emetic. The whole herb is somewhat expectorant.
When the petals are collected and dried they become of a greenish colour: whilst fresh they have a honey-like odour, and a sweetish taste.
[449] Within the last few years a political significance and popularity have attached themselves to the Primrose beyond every other British wild flower. It arouses the patriotism of the large Conservative party, and enlists the favour of many others who thoughtlessly follow an attractive fashion, and who love the first fruits of early Spring. Botanically the Primrose has two varieties of floral structure: one "pin-eyed," with a tall pistil, and short stamens; the other "thrum-eyed," showing a rosette of tall stamens, whilst the short pistil must be looked for, like the great Panjandrum himself, "with a little round button at the top," half way down the tube. Darwin was the first to explain that this diversity of structure ensures cross fertilisation by bees and allied insects. Through advanced cultivation at the hands of the horticulturist the Primula acquires in some instances a noxious character. For instance, the Primula biconica, which is often grown in dwelling rooms as a window plant, and commonly sold as such, will provoke an crysipelatous vesicular eruption of a very troublesome and inflamed character on the hands and face of some persons who come in contact with the plant by manipulating it to take cuttings, or in other ways. A knowledge of this fact should suggest the probable usefulness of the said Primula, when made into a tincture, and given in small diluted doses thereof, to act curatively for such an eruption if attacking the sufferer from idiopathic causes.
The Latins named the Ligustrum (our Privet) Primrose. Coles says concerning it (17th century): "This herbe is called Primrose; it is good to 'Potage.'" They also applied the epithet, "Prime rose" to a lady.
The Evening Primrose (OEnothera biennis, or odorata) is found in this country on sand banks in the West of England and Cornwall; but it is then most probably a [450] garden scape, and an alien, its native habitat being in Canada and the United States of America. We cultivate it freely in our parterres as a brilliant, yellow, showy flower. It belongs to the natural order, Onagraceoe, so called because the food of wild asses; and was the "vini venator" of Theophrastus, 350 B.C. The name signifies having the odour of wine, oinos and theera. Pliny said: "It is an herbe good as wine to make the heart merrie. It groweth with leaves resembling those of the almond tree, and beareth flowers like unto roses. Of such virtue is this herbe that if it be given to drink to the wildest beast that is, it will tame the same and make it gentle." The best variety of this plant is the OEnothera macrocarpa.
The bark of the Evening Primrose is mucilaginous, and a decoction made therefrom is of service for bathing the skin eruptions of infants and young children. To answer such purpose a decoction should be made from the small twigs, and from the bark of the larger branches, retaining the leaves. This has been found further of use for diarrhoea associated with an irritable stomach, and asthma. The infusion, or the liquid extract, acts as a mild but efficient sedative in nervous indigestion, from twenty to thirty drops of the latter being given for a dose. The ascertained chemical principle of the plant, OEnotherin, is a compound body. Its flowers open in the evening, and last only until the next noon; therefore this plant is called the "Evening Primrose," or "Evening Star."
