St. John's wort (Hypericum perforatum)
St. John's wort, a plant species of the Hypericaceae family, is a perennial herbaceous plant that grows to a height of 15 to 100 centimetres. It is used as a medicinal plant, especially as a mild antidepressant.
St. John's wort is a tried and tested incense for the summer solstice to protect against lightning and fire and for love oracles. Wreaths of St. John's wort were also woven for this purpose.
