Derivation of the botanical name:
Hypericum, hyper, above, eikon, picture; from the old practice of placing flowers above an image in the house to ward off evil spirits at the midsummer festival of Walpurgis Night, which later became the feast of St. John held in late June when they are in bloom, and thus took the name of St. John's wort.
triquetrifolium, triangular leaved.
crispum, closely curled; finely waved.
The Hebrew name: פרע, Hypericum, the ‘St. John’s wort’, from פרע, to dishevel the hair. Syrian פרע (= it sprouted), Late Arabic: fara 'a ( =it sprouted).
