A sworn foe to the purple clover cultivated by farmers, is the Dodder (_Cuscuta trifolii_), a destructive vegetable parasite which strangles the plants in a crafty fashion, and which goes by the name of "hellweed," or "devil's guts." It lies in ambush like a pigmy field octopus, with deadly suckers for draining the sap of its victims. These it mats together in its wiry, sinuous coils, and chokes relentlessly by the acre. Nevertheless, the petty garotter-- like a toad, "ugly and venomous, wears yet a precious jewel in its head." "If boiled," says Hill, "with a little ginger, the dodder in decoction works briskly as a purge. Also, the thievish herb, when bruised and applied externally to scrofulous tumours, is an excellent remedy." The word "dodder" signifies the plural of "dodd," a bunch of threads. The parasite is sometimes called "Red tangle" and "Lady's laces." Its botanical name _Cuscuta_ comes from the Greek _Kassuo_--to sew together. If the piece of land infested with it is closely mown (and the cut material carried away unshaken), being next covered with deal saw-dust, on which a ten per cent. solution of sulphate of iron is freely poured, then by combining with the tannin contained in the stems of the Dodder, this will serve to kill the parasite without doing any injury to the clover or lucerne. Although a parasite the plant springs every year from seed. It is a remedy for swooning or fainting fits. The Sweet Clover (or yellow Melilot), when prepared as a tincture (H.), with spirit of wine, and given as a medicine in material doses, causes, in sensitive persons, a severe headache, sometimes with a determination of [113] blood to the head, and bleeding from the nose. When administered, on the principle of curative affinity, in much smaller doses, it is singularly beneficial against nervous headaches, with oppression of the brain, acting helpfully within five minutes. Dr. Hughes (Brighton) writes: "I value this medicine much in nervous headaches, and I always carry it in my pocket-case-- as the mother tincture--which I generally administer _by olfaction_." For epilepsy, it is said in the United States of America to be "the one grand master-remedy," by giving a drop of the tincture every five minutes during the attack, and five drops five times a day in water, for some weeks afterwards.
