Poison ivy, oak, and sumac are plants that can cause a red, itchy rash called allergic contact dermatitis. It is the most common skin problem caused by contact with plants. The rash is caused by contact with a sticky oil called urushiol (say yoo-ROO-shee-all) found in poison ivy, oak, or sumac.
For other uses, see Superstition (disambiguation). Superstition is a popular song composed, produced, arranged, and performed by Stevie Wonder for Motown Records in 1972. It was the lead single for Wonder's album Talking Book, and released in many countries. It reached number one in the U.S., and number one on the soul singles chart.
The word superstition is sometimes used to refer to religious practices (e.g., Voodoo) other than the one prevailing in a given society (e.g. Christianity in Western culture), although the prevailing religion may contain just as many superstitious beliefs.his in turn led to studies of biblical exegesis, pioneered by Spinoza and to a more skeptical view about superstition. Opposition to superstition was central to 17th century rationalist Benedict de Spinoza and the intellectuals of the 18th century Age of Enlightenment.
