Poison Ivy Spreading

Urushiol oil or resin is contained in the leaves, roots, and woody parts such as vines and stems of the poison ivy, oak, and sumac plants. It is a clear substance that is discharged by the plant when it is sliced or scrapped. Leaves are scrapped easily, especially in the spring, so even a delicate stroke against a plant can cause the urushiol to release out and onto the skin.

Urushiol can remain potent for years. For that basis, even dead poison ivy, oak, or sumac plants must be treated with care. Plants should never be inflamed or chopped, as airborne particles can diffuse the oil to sensitive parts like the face and eyes and may possibly cause damage to lungs.

The three basic sources of poison plant irritation-poison ivy, poison oak, and poison sumac-are part of the Anacardiacea, or cashew species. While they are generally concentrated most widely in a few specific regions of the countryside, all three have been seen in locations throughout the United States. Recognizing the plant, particularly if people reside in a wooded area or have a lot of plants in their back yards or neighborhood is necessary to preventing the irritation.
Poison ivy, called as Rhus radicans or Toxicondendron radicans , is located throughout the United States. The plant emerges in vines usually in the Midwest, East coast, and South or small bushes in the North, West, and Great Lakes parts. It has clumps of three leaves. The leaves are colored red in the spring, green during the summer, and yellow, red, and orange throughout the fall when they also generate white berries.

Poison oak is a little shrub. The plant, which is also called as Rhus diversiloba or Toxicondendron diversilobum, is located in the western United States. Like poison ivy, poison oak leaves transforms color with the seasons. The plant also makes white berries in the fall.

The small, woody shrubs that are poison sumac are most usual in the Eastern United States. Also called as Rhus vernix or Toxicondendron vernix , poison sumac varies in characteristics from the three-leaf clumps of poison ivy and oak. It is feather-like in nature, with two rows of leaves located on either side of a long stem, mounted off by a long leaf at the tip. It can be determined from regular, non-poisonous sumac by its berries, which are green to white in contrast to the bright red berries of usual sumac.

According to the experts in Dermatology, about 85 percent of the population is allergic to the urushiol oil contained in poison ivy, oak, and sumac. Annually, up to 50 million Americans acquires a poison ivy, oak, or sumac rash. The possibility of having an allergic sensitivity to these poison plants minimizes with age, and adults who have never been in contact to urushiol only have a 50 percent possibility of having contact dermatitis when comes in contact to poison ivy, oak, or sumac.

Additionally, allergic sensitivity to poison plants tends to decrease with age. It is feasible for children who are highly irritated to urushiol to become into adults who are rarely sensitive to poison ivy, oak, or sumac, regardless of how often they have been in contact to the plant oil.
