St. John's worth

Also known as: Hypericum
Latin: Hypericum perforatum
Macedonian: Kantarion, Zholt kantarion, Kanturija, Zasekliva treva
Parts used: Flowers and upper part of the herb


Among the many medicinal herbs used throughout the long history of Occidental culture, St. John's wort, Hypericum perforatum L., has always been and still is of great interest. From the time of the ancient Greeks down through the Middle Ages, the plant was considered to be imbued with magical powers and was used to ward off evil and protect against disease. As a practical folk-remedy, it has been used widely to heal wounds, remedy kidney troubles, and alleviate nervous disorders, even insanity, and recent research makes a provocative statement about the ancient uses of St. John's wort by showing that it is a modern protector against depression and virus infection--two modern demons in their own right.
The herb takes its name, dating back to the 6th Century A.D., from the red spots that appeared on the plant's leaves and were thought to be symbolic of the blood of St. John. Wort is an Old English word for herb. St. John's Wort has been used for over 2,000 years for such traditional uses as healing wounds, soothing nervous disorders and relieving kidney troubles .
Paracelsus wrote of the plant in the early 1500's that it could be used as an amulet against enchantments and apparitions. St. John's wort was used in early pre-Christian religious practices in England, and it has many legends written about it. For instance, one belief was that bringing the flowers of St. John's wort into the house on a midsummer eve would protect one from the evil eye, banish witches, etc. Another belief was that that if one slept with a piece of the plant under one's pillow on St. John's Eve, "the Saint would appear in a dream, give his blessing, and prevent one from dying during the following year" (17). The favor St. John's wort enjoyed is well expressed in the following 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.
Because of its bright yellow color, it was often associated with the sun and was often used for purposes of divination--for every situation from longevity to test one's chances for matrimony. This poem is translated from the German, where this custom was also practiced:
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”.
The tops of Hypericum were also considered effective for keeping away undesirable influences and bringing luck. For instance, one belief was that bringing the flowers of St. John's wort into the house on a midsummer eve would protect one from the evil eye, banish witches, promote good fortune and protect the house from fire.
