Poison-ivy is classified as a noxious weed under the Ontario Weed Control Act. This legislation provides a means for regulating control of certain weeds in problem areas. Each municipal council, through its weed inspector, is responsible for the degree of control within its district. Curtisa G, Lewis AC. Treatment of severe poison ivy: a randomized, controlled trial of long- versus short-course oral prednisone. J Clin Med Res. 2014; 6(6):429–434. [ PMC free article] [ PubMed] [ Google Scholar] Treatment. The patient in this case report was one of approximately 500,000 cases of TCD reported each year in the United States. 17 The patient’s treatment with oral prednisolone prior to being seen by the dermatology clinic was typical but did not relieve his symptoms, nor did the calamine lotion or oral diphenhydramine. 1 , 13 Fragrant sumac ( Rhus aromatica) is often mistaken for poison oak, and both grow in similar habitats. One difference is that the leaflets of fragrant sumac are attached at a single point, while the terminal leaflet of poison oak has a short stem. Also, the fruit of the fragrant sumac plant is red (figure 10). The Poison Ivy Premium Format Figure measures 18” tall and 11” wide as Pamela Isleyreclines on some vines that have destroyed the Gotham City Police Department building. Rusted cell bars bend and break under her botanical strength and Ivy’s darling carnivorous plants infest the precinct, taking a bite out of crime … from the rogue's perspective.

History. Poison ivy is neither poisonous nor a true member of the Ivy family (Hedera). Instead, it is a member of the Anacardiaceae family, which also includes pistachios, cashews, and mangoes. All members of the Anacardiaceae family contain various forms of pentadecylcatechols within their sap, which is collectively termed urushiol, an oleoresin released from the injured leaves, stems, vines, or berries of these plants. 7These herbicides can be bought in various concentrations and under many different trade or brand names. Therefore, it is not feasible in this Factsheet to give detailed instructions for mixing and application of each kind. Detailed directions for its use are printed on the label on every container of each herbicide. Follow the manufacturer's directions. For safety's sake, read the label carefully and observe all precautions printed on it.

Although the leaflets are somewhat oval, they vary greatly in shape and size. Their margins vary from perfectly smooth ( Figure 3A) to finely or coarsely toothed ( Figure 3D), to deeply and irregularly lobed ( Figure 3E). Undersides of the leaflets may be finely hairy all over, or just along the veins and veinlets, or may be virtually without hairs. Touching any of the three poisonous species may result in a red, swollen, and painful rash of itchy blisters. Rashes can occur in patches or in streaks and lines.

While there is no entirely satisfactory treatment for TCD other than the “tincture of time,” longer-course glucocorticoid therapy, such as triamcinolone or prednisone, has been shown to be effective in relieving symptoms associated with TCD. 8 Short courses of low-dose methylprednisolone (so-called “dose paks”) are too brief and too weak to offer effective relief. Glucocorticoids should be administered using a 2- to 3-week taper starting with 60mg daily (preferably taken in the morning with food to avoid gastritis) for five days that is reduced to 40mg daily for five days and then down to 20mg daily for five days. 9 , 8 Contraindications for glucocorticoids include concurrent infection, peptic ulcer disease, poorly controlled hypertension, congestive heart failure, and diabetes. 9 Dementia can also be made worse with systemic steroids (so-called “steroid psychosis”). 9 Less serious side effects of systemic glucocorticoids include an increase in appetite, retention of fluid (edema), irritability, and insomnia. Adrenal suppression associated with prolonged systemic steroid use is rarely a problem when using a 2- to 3-week course of glucocorticoid therapy for poison ivy. 9

Figure 3. Poison ivy vines, ranging in size from the thin new one on the right to the large hairy ones on the left. Note that the new stems are not as hairy. (Photo by Amber C. Marable) Approximately 10 to 15 percent of people will have reactions severe enough to require medical treatment, often in the form of oral or injected low-dose steroids administered by a doctor. Seek medical help if the rash becomes infected, covers a large part of the body, causes swelling of the face or other sensitive areas, or causes difficulty with swallowing or breathing. Figure 7. Virginia creeper vines are generally less “hairy” than poison ivy vines. There are some short rootlets. Note the clasping rootlets that have what look like small suction cups at the tips. Figure 1. Poison ivy leaves have three leaflets. Leaflets have scattered, jagged teeth along the edges and may have a larger tooth or lobe close to the bottom edge of the leaflet, giving it a mitten-like shape. There is often a red spot where the bottom two leaflets join together. TCD places a financial burden on our economy and utilizes substantial healthcare resources. For example, outdoor occupations related to agriculture, forestry, and firefighting are at high risk of exposure to poison ivy, and when affected, these workers incur significant monetary expense for worker disability and medical treatments.TCD is responsible for 10 percent of the total US Forest Services lost work time due to injuries. 17Templeton D. Climate change is making poison ivy bigger and badder. https://www.post-gazette.com/news/health/2013/07/22/Climate-change-is-making-poison-ivy-grow-bigger-and-badder/stories/201307220149 22 Jul 2013. Pittsburg Post Gazette. Accessed 22 Sep 2020. About 85 percent of people are allergic to urushiol, the oily compound responsible for the skin reaction. Urushiol is found in all parts of these plants. Simply touching the leaves may expose you to the oil, and additional oil is released when plant parts are crushed or damaged. The oil resists breakdown and may cling to clothing, tools, and pet fur for long periods of time, even a year or more. Exposure to the oil on these secondary sources can also cause an allergic reaction. Many plants have been mistaken for poison-ivy because their leaves may also consist of 3 leaflets. These can be distinguished from poison-ivy as follows. Poison-ivy ( Rhus radicans L.) is widespread throughout southern Ontario and reaches north approximately as far as Cochrane and Kenora. It is found most abundantly, however, south of a line from the north shore of Lake Huron through North Bay. This includes the densely populated portions of the province and the popular vacation areas. The plant is often mistakenly called "poison oak", but the true poison oak occurs only in the southern and Pacific states of the U.S.A. and not in Ontario. Caution! Even at this stage take care as poisoning may be brought about by handling the dead plants.

Poison ivy’s original classification, Toxicodendron radicans (T. radicans), was first established by the French botanist Joseph Pitton de Tournefort in the 17th century. Later, Carl Linnaeus, considered the “Father of Taxonomy,” classified poison ivy, poison oak, and poison sumac under the Rhus genus in 1737. 8 However, by the 18th century, 27 species of Rhus had been identified, with numerous variations, creating the need to better clarify the taxonomic designations of plants falling into the Rhus genus. Thus, the genus Toxicodendron, which means “poison tree,” was reprised for what we know today as poison ivy, poison oak, and poison sumac, with radicans and rydbergii being the most common species. Poison oak ( T. diversilobum) is more common in western United States, and poison sumac ( T. vernix) is primarily confined to marshy areas of eastearn and southeastern United States, but numerous types of Toxicodendron plants can be found in temperate climates all over the world. 7 Sideshow presents the Poison Ivy Premium Format™ Figure, an irresistible, exclusive DC Comics collectiblethat’s sure to ensnare your senses.

The leaves of poison ivy (figure 1) and poison oak (figure 2) have three leaflets. This is where the adage leaves of three, let it be comes from. The leaflets are commonly 2 to 8 inches long and 3⁄4 to 5 inches wide, and they have scattered, jagged teeth along the edges. Some have a larger tooth or lobe close to the bottom edge, giving them a mitten-like shape. Eating the plants can cause severe internal irritation, and inhaling particles of urushiol released by burning poison ivy, oak, or sumac can cause swelling of the respiratory passages, which can even result in death. These cases require specific and immediate medical treatment. Control
