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." Another of the Primrose tribe, the Cyclamen, or Sow-bread (_Panis porcinus_), is often grown in our gardens, and for ornamenting our rooms as a pot plant. Its name means (Greek) "a circle," and refers to the reflected corolla, or to the spiral fruit-stalks; and again, [451] from the tuber being the food of wild swine. Gerard said it was reported in his day to grow wild on the Welsh mountains, and on the Lincolnshire hills: but he failed to find it. Nevertheless it is now almost naturalised in some parts of the South, and East of England. As the petals die, the stalks roll up and carry the capsular berries down to the surface of the ground. A medicinal tincture is made (H.) from the fresh root when flowering. The ivy-leaved variety is found in England, with nodding fresh-coloured blossoms, and a brown intensely acrid root. Besides starch, gum, and pectin, it yields chemically, "cyclamin," or "arthanatin," with an action like "saponin," whilst the juice is poisonous to fish. When applied externally as a liniment over the bowels, it causes them to be purged. Gerard quaintly and suggestively declares "It is not good for women with childe to touch, or take this herbe, or to come neere unto it, or to stride over the same where it groweth: for the natural attractive vertue therein contained is such that, without controversie, they that attempt it in manner above said, shall be delivered before their time; which danger and inconvenience to avoid, I have fastened sticks in the ground about the place in my garden where it groweth, and some other sticks also crosswaies over them, lest any woman should by lamentable experiment find my words to be true by stepping over the same. Again, the root hanged about women in their extreme travail with childe, causeth them to be delivered incontinent: and the leaves put into the place hath the like effect." Inferentially a tincture of the plant should be good for falling and displacement of the womb. "Furthermore, Sowbread, being beaten, and made into little flat cakes, is reputed to be a good amorous medicine, to make one in love." [452] In France, another Primula, the wild Pimpernel, occurs as a noxious herb, and is therefore named Mouron.
