Hyssop-Leaved Thoroughwort

This large family (Asteraceae), commonly called the Aster Family, consists of 1,314 genera and 21,000 species of herbs, shrubs, climbers and a few trees is found chiefly in temperate and subtropical regions.  The plants are of value to man as ornamentals; a few are insecticides and fish poisons. The genus Eupatorium means “of Eupator” and refers to Mithridates Eupator, king of Parthia, 120-63 B.C..  He was one of Rome’s most formidable opponents, and he was supposed to have discovered the medicinal virtues of the Eupatoriums.  The species hyssopifolium refers to the shape of the leaves of Hyssop-Leaved  Thoroughwort. The name “Hyssop” comes from Old English hysope and Old Frenchysope, both from Latin hyssopus, and from Greek hussopos. Plants in this genus, Eupatorium, have medicinal uses.  The common name “Thoroughwort” refers to the “thoroughness” with which this herb cures medical problems.  “Wort” is the old name for herb.  In an index of plants with medicinal uses published in 1958, Hyssop-Leaved Thoroughwort was noted as “The entire plant is antivenomous and may be used as a remedy for bites of reptiles and insects by brushing and applying to the wound”.
