St John's Wort
St. John's wort (also known as Goat Weed, Hardhay, Touch and Heal, and Tipton Weed among many other names) is usually found growing in dry areas, such as the edges of fields and along roadsides in many temperate climates. It is a shrub-like weed that spreads rapidly and invades cultivated land unless controlled. St. John's Wort is most often observed as an obnoxious plant and is usually avoided by livestock, as its properties serve to be both medicinal and toxic.
