Each year on Midsummer’s Eve, when summer begins here in New England, I stroll around my garden searching for the little yellow blooms of St. John’s Wort (Hypericum perforatum). I’ve never planted any. Around here it grows as a wildflower, and a few volunteers show up each year, in various places, sometimes the same and sometimes not. From the time of the ancient Greeks, it was considered to have magical powers to ward off evil and protect against diseases, and since early Christian times, the feast of St. John the Baptist, June 24, has been considered the best day on which to pick the plant for such uses. Some sources have said the red spots appear on the leaves on August 29, said to be the anniversary of his beheading.
Other ideas stem from folk beliefs. The bright yellow blossom was associated with the sun, which made St. John’s Wort popular for divination and fortune telling. In Germany, for example, young girls dreaming about marriage in the coming year would pick a sprig in the evening; if it had not wilted by morning, her chances were good. The red juice from the crushed leaves was called Witch’s Blood, and made effective love potions. A poem translated from the German:
“The young maid stole through the cottage door,
And blushed as she sought the plant of power.
‘Thou silver glow-worm, oh! lend me thy light,
I must gather the mystic St. John’s Wort to-night;
The wonderful herb whose leaf will decide
If the coming year shall see me a bride.”
Similarly, it could foretell who in a family would die the soonest. Bringing the flowers indoors on Midsummer Eve would protect from the evil eye, ward off witches, promote good fortune, and prevent fires and lightning strikes. (Guess I’d better bring some in tonight!) Placing a bunch beneath a pillow could banish nightmares, and in one case it rid a house of poltergeist activity! From an English poem:
“St. John’s wort doth charm all the witches away.
If gathered at midnight on the saint’s holy day.
And devils and witches have no power to harm
Those that do gather the plant for a charm:
Rub the lintels and post with that red juicy flower
No thunder nor tempest will then have the power
To hurt or to hinder your houses: and bind
Round your neck a charm of a similar kind.”
Be sure not to step on this plant, or a Faerie Horse just may steal you away. But perhaps you can avoid that fate by wearing a few leaves and flowers as a necklace.
Medicinally, noted herbalists used St. John’s Wort in ointments to heal deep wounds, bruises, and venomous animal bites. In infusions, it could dissolve stones in the urinary tract or kidneys, and cure fevers, jaundice, gout, and rheumatism. It was also good for bed sores, lockjaw, and insomnia. Native Americans made use of St. John’s Wort against diarrhea, skin injuries, bleeding, and snake bites. In Europe, it has been used for centuries to alleviate nervous disorders, hysteria, and insanity, and very recently, St. John’s Wort has been newly discovered as a modern treatment for depression and virus infection. Today, there are many commercial preparations available as standard oils and liquid or powdered extracts. Now that researchers are taking this herb seriously for medicinal purposes, who knows what knew applications might be discovered?
