On the other hand, certain plants have been credited at most periods with hurtful and injurious properties. Thus, there is a popular idea that during the flowering of the bean more cases of lunacy occur than at any other season. [17] It is curious to find the apple—such a widespread curative—regarded as a bane, an illustration of which is given by Mr. Conway. [18] In Swabia it is said that an apple plucked from a graft on the whitethorn will, if eaten by a pregnant woman, increase her pains. On the Continent, the elder, when used as a birch, is said to check boys' growth, a property ascribed to the knot-grass, as in Beaumont and Fletcher's "Coxcomb" (Act ii. sc. 2):—

"We want a boy extremely for this function,
Kept under for a year with milk and knot-grass."

The cat-mint, when chewed, created quarrelsomeness, a property said by the Italians to belong to the rampion.

Occasionally much attention in folk-medicine has been paid to lucky numbers; a remedy, in order to prove efficacious, having to be performed in accordance with certain numerical rules. In Devonshire, poultices must be made of seven different kinds of herbs, and a cure for thrush is this:—"Three rushes are taken from any running stream, passed separately through the mouth of the infant, and then thrown back into the water. As the current bears them away, so, it is believed, will the thrush leave the child."

Similarly, in Brandenburg, if a person is afflicted with dizziness, he is recommended to run after sunset, naked, three times through a field of flax; after doing so, the flax will at once "take the dizziness to itself." A Sussex cure for ague is to eat sage leaves, fasting, nine mornings in succession; while Flemish folk-lore enjoins any one who has the ague to go early in the morning to an old willow, make three knots in one of its branches, and say "Good morrow, old one; I give thee the cold; good morrow, old one." A very common cure for warts is to tie as many knots on a hair as there are warts, and to throw the hair away; while an Irish charm is to give the patient nine leaves of dandelion, three leaves being eaten on three successive mornings. Indeed, the efficacy of numbers is not confined to any one locality; and Mr. Folkard [19] mentions an instance in Cuba where, "thirteen cloves of garlic at the end of a cord, worn round the neck for thirteen days, are considered a safeguard against jaundice." It is necessary, however, that the wearer, in the middle of the night of the thirteenth day, should proceed to the corner of two streets, take off his garlic necklet, and, flinging it behind him, run home without turning round to see what has become of it. Similarly, six knots of elderwood are employed "in a Yorkshire incantation to ascertain if beasts are dying from witchcraft." [20] In Thuringia, on the extraction of a tooth, the person must eat three daisies to be henceforth free from toothache. In Cornwall [21] bramble leaves are made use of in cases of scalds and inflammatory diseases. Nine leaves are moistened with spring-water, and "these are applied to the burned or diseased parts." While this is being done, for every bramble leaf the following charm is repeated three times:—

"There came three angels out of the east,
One brought fire and two brought frost;
Out fire and in frost,
In the name of the Father, Son, and Holy Ghost."

Of the thousand and one plants used in popular folk-medicine we can but give a few illustrations, so numerous are these old cures for the ills to which flesh is heir. Thus, for deafness, the juice of onion has been long recommended, and for chilblains, a Derbyshire cure is to thrash them with holly, while in some places the juice of the leek mixed with cream is held in repute. To exterminate warts a host of plants have been recommended; the juice of the dandelion being in favour in the Midland counties, whereas in the North, one has but to hang a snail on a thorn, and as the poor creature wastes away the warts will disappear. In Leicestershire the ash is employed, and in many places the elder is considered efficacious. Another old remedy is to prick the wart with a gooseberry thorn passed through a wedding-ring; and according to a Cornish belief, the first blackberry seen will banish warts. Watercress laid against warts was formerly said to drive them away. A rustic specific for whooping-cough in Hampshire is to drink new milk out of a cup made of the variegated holly; while in Sussex the excrescence found on the briar, and popularly known as "robin red-breast's cushion," is in demand. In consumption and diseases of the lungs, St. Fabian's nettle, the crocus, the betony, and horehound, have long been in request, and sea-southern-wood or mugwort, occasionally corrupted into "muggons," was once a favourite prescription in Scotland. A charming girl, whom consumption had brought to the brink of the grave, was lamented by her lover, whereupon a good-natured mermaid sang to him:—

"Wad ye let the bonnie May die in your hand,
And the mugwort flowering i' the land?"

Thereupon, tradition says, he administered the juice of this life-giving plant to his fair lady-love, who "arose and blessed the bestower for the return of health." Water in which peas have been boiled is given for measles, and a Lincolnshire recipe for cramp is cork worn on the person. A popular cure for ringworm in Scotland is a decoction of sun-spurge (Euphorbia helioscopia), or, as it is locally termed, "mare's milk." In the West of England to bite the first fern seen in spring is an antidote for toothache, and in certain parts of Scotland the root of the yellow iris chopped up and chewed is said to afford relief. Some, again, recommend a double hazel-nut to be carried in the pocket, [22] and the elder, as a Danish cure, has already been noticed.

Various plants were, in days gone by, used for the bites of mad dogs and to cure hydrophobia. Angelica, madworts, and several forms of lichens were favourite remedies. The root of balaustrium, with storax, cypress-nuts, soot, olive-oil, and wine was the receipt, according to Bonaventura, of Cardinal Richelieu. Among other popular remedies were beetroot, box leaves, cabbage, cucumbers, black currants, digitalis, and euphorbia. [23] A Russian remedy was Genista sentoria, and in Greece rose-leaves were used internally and externally as a poultice. Horse-radish, crane's-bill, strawberry, and herb-gerard are old remedies for gout, and in Westphalia apple-juice mixed with saffron is administered for jaundice; while an old remedy for boils is dock-tea. For ague, cinquefoil and yarrow were recommended, and tansy leaves are worn in the shoe by the Sussex peasantry; and in some places common groundsel has been much used as a charm. Angelica was in olden times used as an antidote for poisons. The juice of the arum was considered good for the plague, and Gerarde tells us that Henry VIII. was, "wont to drink the distilled water of broom-flowers against surfeits and diseases thereof arising." An Irish recipe for sore-throat is a cabbage leaf tied round the throat, and the juice of cabbage taken with honey was formerly given as a cure for hoarseness or loss of voice. [24] Agrimony, too, was once in repute for sore throats, cancers, and ulcers; and as far back as the time of Pliny the almond was given as a remedy for inebriety. For rheumatism the burdock was in request, and many of our peasantry keep a potato in their pocket as charms, some, again, carrying a chestnut, either begged or stolen. As an antidote for fevers the carnation was prescribed, and the cowslip, and the hop, have the reputation of inducing sleep. The dittany and plantain, like the golden-rod, nicknamed "wound-weed," have been used for the healing of wounds, and the application of a dock-leaf for the sting of a nettle is a well-known cure among our peasantry, having been embodied in the old familiar adage:—
