All herbs pulled on May Day Eve have a sacred healing power, if pulled in the name of the Holy Trinity; but if in the name of Satan, they work evil. Some herbs are malific if broken by the hand. So the plant is tied to a dog’s foot, and when he runs it breaks, without a hand touching it, and may be used with safety.
A man pulled a certain herb on May Eve to cure his son who was sick to death. The boy recovered, but disappeared and was never heard of after, and the father died that day year. He had broken the fatal herb with the hand and so the doom fell on him.
Another man did the like, and gave the herb to his son to eat, who immediately began to bark like a dog, and so continued till he died.
The fatal herbs have signs known only to the fairy doctors, who should always be consulted before treating the sick in the family.
There are seven herbs that nothing natural or supernatural can injure; they are vervain, John’s-wort, speedwell, eyebright, mallow, yarrow, and self-help. But they must be pulled at noon on a bright day, near the full of the moon, to have full power.
It is firmly believed that the herb-women who perform curses receive their knowledge from the fairies, who impart to them the mystical secrets of herbs and where to find them; but these secrets must not be revealed except on the death-bed, and then only to the eldest of the family. Many mysterious rites are practised in the making and the giving of potions; and the messenger who carries the draught to the sufferer must never look behind him nor utter a word till he hands the medicine to the patient, who instantly swallows a cup of the mixture before other hands have touched it.
A celebrated doctor in the south was an old woman, who had lived seven years with the fairies. She performed wonderful cures, and only required a silver tenpence to be laid on her table for the advice given and for the miraculous herb potion.
A LOVE POTION.
Some of the country people have still a traditional remembrance of very powerful herbal remedies, and love potions are even now frequently in use. They are generally prepared by an old woman; but must be administered by the person who wishes to inspire the tender passion. At the same time, to give a love potion is considered a very awful act, as the result may be fatal, or at least full of danger.
