The Spanish Needle is scientifically called Bidens Pilosa. It is a medical herb that is native to Southern America. Although it is largely considered a weed, it has become common a source of medicine and food in many parts of the world. This annual herb grows aggressively and it could climb to a height of about 2 meters. The Bidens Pilosa’s leaves are arranged oppositely and have a resinous flavor. The leaves can be eaten in stews, raw, or stored dried. It is a natural-growing plant in Jamaica and it is sometimes called by different names, such as Needle Grass, Beggars Tick, Black Jack, Demon Spike Grass, and Broomstick.
