Chicory, when taken too habitually or too freely, causes venous passive congestion in the digestive organs within the abdomen, and a fulness of blood in the head. Both it and Succory, if used in excess as a medicine, will bring about amaurosis, or loss of visual power in [543] the retina of the eyes. Therefore, when given in a much diluted form they are remedial for these affections.
The only benefit of quality which Chicory gives to coffee is by increase of colour and body, with some bitterness, but not by possessing any aroma, or fragrant oil, or stimulating virtue. French writers say it is contra-stimulante, and serving to correct the excitation caused by the active principles of coffee, and therefore it suits sanguineo-bilious subjects who suffer from habitual tonic constipation. But it is ill adapted for persons whose vital energy soon flags; and for lymphatic, or bloodless people its use should be altogether forbidden.
The flowers of Succory used to rank among the four cordial flowers, and a water was distilled from them to allay inflammation of the eyes. The seeds contain abundantly a demulcent oil, whilst the petals furnish a glucoside which is colourless unless treated with alkalies, when it becomes of a golden yellow.
SUNDEW.
The Sundew (Ros solis, or Drosera rotundifolia) is a little plant always eagerly recognised in marshy and heathy grounds by ardent young botanists. In the sun its leaves seem tipped with dew (drosos). It grows plentifully in Hampshire and the New Forest, bearing a cluster of hairy leaves in a stellate form, at the top of a slender stem. These leaves either from lack of other sustenance in so barren a soil, or more probably as an advance in plant evolution to a higher grade of development, excrete a sticky moisture or dew, which entangles unwary flies settling on the plant, and which serves to digest these victims therewith. Each of the long red [544] hairs on the leaves is viscid, and possesses a small secreting gland at its top.
Some writers say the word Sundew means "sin" ever, moist (dew). The plant is also called Redrot, and Moor Grass, because the soil in which it grows is unwholesome for sheep.
It goes further by the additional names of Youthwort, and Lustwort—quia acrimonia sua sopitum veneris desiderium excitat (Dodoeus). The fresh juice of the herb contains malic acid in a free state, various salts, and a red colouring matter; also glucose, and a peculiar crystallisable acid. Cattle of the female gender are said to have their copulative instincts excited by eating even a small quantity of the plant. Throughout Europe it has long been esteemed a remedy of repute for chronic bronchitis and asthma; and more recently, in the hands of homoeopathic practitioners, it has acquired a fame for specifically curing whooping cough in its spasmodic stages, after the first feverishness of this malady has become subdued. It signally lessens the frequency and force of the spasmodic attacks, besides diminishing the sickness.
Provers who have pushed on themselves the administration of the Sundew in toxical quantities, developed hoarseness, with expectoration of yellow mucus from the throat and upper lungs, as well as a hacking cough, and loss of flesh, this combination of symptoms closely resembling the form of tubercular consumption which begins in the throat, and extends mischievously to the lungs. Regarded from such point the Sundew may be justly pronounced a homoeopathic antidote to consumptive disease of the nature here indicated, when attacking spontaneously from constitutional causes.
[545] Moreover, country folk notice that sheep who eat the Sundew in their pasturage have often a violent cough, and waste away. Dr. Curie, of Paris, fed cats with this plant, and they died subsequently with all the symptoms of lung consumption, their chest organs being afterwards found studded with tubercular deposit though cats are not ordinarily liable to tubercle.
So the Sundew may fairly be accepted as a medicinal Simple for laryngeal and pulmonary consumption in its early stages, as well as for whooping-cough, after the manner already explained. A tincture is made (H.) from the entire fresh plant, with spirit of wine, of which a couple of drops may be given in water several times a day, to a child of from four to eight years old, for confirmed whooping-cough; and if this dose seems to aggravate the paroxysms, or to provoke sickness, it must be reduced in strength, and dilution.
