SEARCH Poison Ivy Poison ivy is the common name given to a plant which can cause an unpleasant, itchy rash (as you probably already know). Here are some facts about the plant and the rash that might help you work and play outdoors more comfortably. What is poison ivy and how can I identify it? The plant is extremely common in Bloomington and in the country surrounding the city. It is a versatile plant, and usually grows as a vine on trees, rock walls, or buildings. If there is no such support nearby, poison ivy will grow as a small bush or shrub. Poison ivy has a number of relatives which can cause an identical rash on sensitive persons. This group includes poison oak, poison sumac (which doesn't grow here), the cashew tree, the mango (mango fruit, not the green pepper), and the fruit of the Ginkgo tree. A typical poison ivy leaf is made up of three leaflets, all joined together to a common stalk. The leaflet stems at the point where they join are often colored slightly reddish (but not always). The leaflets may have toothed edges (as in poison oak) or may be smooth. Grape-like clumps of greenish, then white berries appear in mid-summer, and in fall the leaves turn an attractive orange-yellow or red. How does poison ivy cause a rash?

KidsHealth Teens Staying Safe Leaves of three - let them be! You've probably heard that little rhyme about poison ivy. But did you know that poison ivy, poison oak, and poison sumac all contain the same rash-causing substance? It's called urushiol (pronounced: yoo- roo -shee-ol), a colorless, odorless oil (called resin) contained in the leaves of the plants. What Are the Signs and Symptoms of Poison Ivy? Urushiol is considered an allergen because it causes an allergic reaction - which takes the form of a rash, itching, and sometimes swelling. Not everyone gets a reaction to urushiol, but about 60% to 80% of people do. This reaction can appear within hours of coming into contact with urushiol or as late as 5 days later. Typically, the skin becomes red, itchy, and swollen and blisters will appear. After a few days, the blisters may become crusty and start to flake off. The rash that people get from poison ivy takes 1 to 2 weeks to heal. Should I See a Doctor? It's a good idea to consult with your doctor if you have any kind of rash, especially if you have a fever too. If your doctor determines that a rash has been caused by poison ivy or a similar plant, he or she may tell you to take cool showers and to use a soothing lotion, such as calamine lotion. In more severe cases, doctors may prescribe pills or creams that contain antihistamines or steroids (not the same type of steroids that bodybuilders use!) to decrease itching and redness.

But did you know that poison ivy, poison oak, and poison sumac all contain the same rash-causing substance? It's called urushiol (say: yoo- roo -shee-ol), a colorless, odorless oil (called resin) contained in the leaves of the plants. Look Out for Poison Plants These plants can be anywhere - from the woods to your own backyard. The green leaves of poison plants blend right in with other plants and brush, so it's possible to sit down in a patch of poison ivy and not even notice. You might notice later, of course, when you start to itch! And it's not enough just to know what one kind of poison ivy looks like. Poison ivy comes in several types - and may look different depending on the time of year. The leaves of poison plants release urushiol when they're "injured," meaning if they get bumped, torn, or brushed up against. Once the urushiol has been released, it can easily get on a person's skin , where it often causes trouble. When the oil is released, the leaves may appear shiny or you may see black spots of resin on them.

Toolbox Poison ivy, poison oak, and poison sumac are plants that contain an irritating, oily sap called urushiol. Urushiol triggers an allergic reaction when it comes into contact with skin, resulting in an itchy rash, which can appear within hours of exposure or three to five days later. A person can be exposed to urushiol directly or by touching objects such as gardening tools, camping equipment, and even a pet's fur that have come into contact with the sap of one of the poison plants. Urushiol is found in all parts of these plants, including the leaves, stems, and roots, and is even present after the plant has died. Urushiol is absorbed quickly into the skin. It can also be inhaled if the poison plants are burned. The smoke may expose not only the skin to the chemical but also the nasal passages, throat, and lungs. Inhaled urushiol can cause a very serious allergic reaction.

Disposal of Poison-Ivy Description Poison-ivy (Rhus radicans L.) is a climbing plant of the sumac family and can be found in every province except Newfoundland. It grows on sandy, stony or rocky shores, sprouts in thickets, in clearings and along the borders of woods. This glossy perennial can spread by seed or by producing shoots from its extensive underground stems (rhizomes). The sap of the plant contains an oily resin that causes an irritating inflammation of the skin in most people. All parts of the plant, including the roots, contain this poisonous resin. Most people develop symptoms 24 to 48 hours after contact. The extent of a reaction depends on the individual’s sensitivity and the amount of sap in contact with the skin. The compound leaves of poison-ivy consist of three pointed leaflets; the middle leaflet has a much longer stalk than the two side ones. The leaflet edges can be smooth or toothed but are rarely lobed. The leaves vary greatly in size, from 8 to 55 mm in length. They are reddish when they emerge in the spring, turn green during the summer, and become various shades of yellow, orange or red in the autumn. The plant stems are woody and of two kinds. The most frequent kind grows as a trailing vine, with upright leafy stalks 10 to 80 cm high. The second kind is an aerial vine that may climb from 6 to 10 m high on trees, posts or rough surfaces.

Poison Oak - A Plant To Avoid Prepared by Robert Smith Mountain News - January 1999 This uncherished native plant of California, the botanical name of which is Toxicodendron diversilobum (an older botanical designation being Rhus diversiloba), is a close relative of poison ivy, which is widespread in the eastern and central United States. The sap oil (urushiol) produces an allergic reaction in most persons who touch it. Regarding Califomia's poison oak, Dr. Glenn Keator writes in his Plants of the East Bay Parks (published by MDIA in cooperation with Roberts Rinehart Publishers, 1994): "Poison Oak has earned for itself an indelible reputation; approach it always with care. Even those who have immunity may later lose it; better to be safe than sorry. Should you touch the twigs (even the bare twigs in winter) or leaves, rinse your hands immediately and wash with mild soap; this should remove oils. Remember to wash your dog if it has accompanied you, and wash your clothes as well." "Despite the consequences of its toxicity, poison oak is an interesting even attractive deciduous shrub. Thriving on disturbance, it has ventured into a wide range of different plant communities, behaving in each one according to circumstances: near the coast it lies prostrate next to the ground; in bright light it forms a dense shrub; in shade it climbs toward the sun, often ascending thirty to forty feet up a tree."

Figure 1 Value and Use Identification Poisoning ... Figure 7 Poison oak is common in western Oregon and Washington. Its near relative, poison ivy, is found in eastern Oregon and Washington, throughout Idaho, and eastward. Both plants are native to the Pacific Northwest. They are so similar in their appearance, growth, effects on humans, and responses to control efforts that their common names often are interchanged. These plants are found in fencerows, waste areas, open forests, hill pastures, cut-over forest lands, stream banks, and rocky canyons in most Pacific Northwest counties. Each autumn, their brilliant red foliage attracts unsuspecting people who gather them for house decoration and then suffer poisoning, sometimes requiring hospitalization. Poisonings are not limited to autumn, however. Swimmers, boaters, fishermen, hikers, and picnickers are most frequently exposed to and poisoned by these plants. These two plants substantially limit the use and enjoyment of our natural environment.

Poison ivy (Toxicodendron radicans) has long-stalked, alternate, three-parted palmate-compound leaves. One leaflet points to the left, one to the right, and one has a stem and points straight ahead. The leaflets have some indentations on the edges that you could almost call teeth. The leaflets range from 4 to 14" long, with pointed tips, and more rounded bases. Their leafstalks are reddish near the leaf’s base. These variable leaves are dark glossy-green most of the season, although they have red overtones when they first appear in the spring, and they turn scarlet in the fall. The plant is so beautiful in autumn, someone brought it to his garden in England, and now the British Isles are blessed with this plant. Young Poison Ivy Leaves photo by "Wildman"

VT Weed ID Guide Home Grass Weed ID Key Scientific Name Index Aquatic Weeds Wildflowers Poison Ivy: Toxicodendron radicans Weed Description: A woody vine that may occur as a weed of landscapes, woods, fencerows, pastures, and hay fields. Poison ivy is the major cause of allergenic dermatitis in the eastern United States, which causes inflammation, blistering, and itching of the skin. The plant sap contains a chemical called urushiol, which is found within ducts in the leaves, flowers, stems, and roots of this weed. When poison ivy plants are bruised or damaged, this chemical is emitted onto the leaf and stem surfaces where humans and animals may come into contact with it. Poison ivy is found throughout the southern United States east of the Mississippi River. It also occurs more sporadically in the midwestern and northern United States. Leaves: Leaves occur on petioles and are divided into 3 leaflets which are generally oval in outline. Leaflets may be either toothed, untoothed, or lobed. Older leaves are generally either toothed and lobed or untoothed and lobed. The two lateral leaflets occur on very short petioles, while the central leaflet occurs on a much longer petiole. Although leaf shape is highly variable, the lateral leaflets are often distinctly lobed on one side of the leaflet and not on the other. Each leaflet is hairless and ranges from 3/4 to 4 inches in length and width.

Cause: Rhus anacardiaceae . - Evergreen or deciduous shrubs or trees. Hardy anywhere and thrive in poor soil. Can cause sever dermatitis on contact; even breathing in smoke from a burning plant is harmful. Poison oak ( Rhus diversiloba ) is common in California, western Oregon and western Washington. In open or filtered sun it grows as a dense, leafy shrub. Where shaded it becomes a tall-climbing vine. Its leaves are divided into 3 leaflets, edges of which are scalloped, toothed or lobed. Poison ivy ( Rhus radicans ) grows in eastern Oregon, eastern Washington (and eastward). It is more sprawling and rarely climbs. Plant has dark brown to black oily substance that is excreted in the woody trunk like sap and on the leaves. Contact with sensitive people can produce sever skin reaction and long-term discomfort. Avoid at all cost. If Rhus is growing on your property, use a full strength chemical brush killer. Then carefully remove the dead growth while remaining completely covered (hat gloves, long sleeve shirt, long pants, mask goggles.) Dispose of or wash clothes in hot water with strong detergent. Wash tools with solvent to remove oil. Secondary contact with oil may cause re-infection of poison oak/ivy. Pathogenesis: The skin reaction from poison ivy/poison oak is a delayed contact hypersensitivity reaction to an oleoresin (uroshiol) which the active sensitizing ingredient is pentadecylcatedhol. Typical skin reactions include itching, redness, papules, vesicles, and bullae. Depending on type of contact with the resin, the reaction may be localized or diffuse. Resin can be contacted from pet fur. Typical reaction can occur as soon as 8 hours after contact and as late as 8 days after contact with the resin. When the reaction shows itself will depend on the degree of exposure, how sensitive the skin is, and where the contact is on the individual. Skin reaction can persist from one to three weeks.

To see some pictures... click on the plant name poison ivy poison oak poison sumac See also jewelweed (used for on-the-trail treatment) Together, they produce more cases of " allergic contact dermatitis " than all other allergens combined. Poison Ivy is by far the most common cause of this allergic skin reaction. The entire plant, except the pollen, is toxic throughout the year, even during the winter months when the branches and stems are leafless. Contact dermatitis simply means that something has been applied to the skin which has caused the skin to react to it. An initial exposure is necessary to "sensitize" the patient; In other words, you get "one free pass". A subsequent exposure will result in an allergic reaction if the plant oil remains in contact with the skin for as little as 10 to 15 miniutes. The resulting rash begins after a 12 to 48 hour delay and persists for about two weeks up to four weeks or longer. The resulting rash can range from mildly unpleasant to a true emergency with intense swelling, blistering, and oozing. With even a moderate case the itching can seem unbearable.

Dealing with Poison Ivy Anyone who has a brush with poison ivy may be tempted to buy an ocean of calamine lotion. An allergic reaction to poison ivy can be uncomfortable, to say the least. According to estimates, about 70 percent of people are sensitive to it. Here are some tips on dealing with the plant. Appearance The best way to avoid that itchy feeling you get from a poison ivy rash is to avoid contact with the plant. The best way to avoid the plant entirely is to know what poison ivy looks like. Poison ivy ( Toxicodendron radicans ) is an adaptable, woody perennial weed that forms vines. The way it grows and looks and its location may vary. Some plants may carpet the ground while others climb tree trunks, stone walls, fences, and posts. The edges of the leaflets may be lobed, smooth or toothed. Poison ivy grows in the open, in deep shade, or along path and road edges. When it grows among other vines, it is more difficult to recognize. Poison ivy plants have a compound leaf arrangement made up of three leaflets on a leafstalk. Two leaflets grow on opposing sides and the third stands by itself at the end of the stalk. Poison ivy leaflets sometimes have hairy undersides. Its stems are woody. The aerial rootlets make the stem look like a fuzzy rope. Each season, poison ivy has a slightly different color and appearance. New springtime growth is often reddish and especially shiny. After the leaves emerge, the plants may develop a cluster of greenish flowers. Poison ivy fruit has a white, waxy appearance, a smooth surface and looks like mistletoe. Summertime foliage is either dull or glossy green. Fall foliage can be yellow, red or orange.

All parts of the poison ivy plant are poisonous. The chemical in it that causes skin irritation is an acidic compound that causes some people to break out in an itchy, unpleasant rash and blisters. Even very small amounts of the compound can cause irritation, and the infection can appear several days after contact. Scratching may break the blisters that form, but these blisters contain body fluids which will not make the rash spread if broken. The rash is spread through contact with the chemical compound itself, which can occur by touching the plant or by handling contaminated articles.
