Product Information

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

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. 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. Mohan J, Ziska L, Clark JS. Biomass and toxicity responses of poison ivy to CO2.

[ PMC free article] [ PubMed] [ Google Scholar]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. 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. 7 Hauser SC.

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).

A. Low-growing form with short erect stems and a flower cluster from the axil of one compound leaf. 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 For additional information on these and other herbicides, and on the selection, care and use of herbicide application equipment see Ontario Ministry of Agriculture and Food Publication 75, Guide to Weed Control. Harmful EffectsA 2- or 3-gallon sprayer is the most convenient method of applying herbicides to patches of poison-ivy. Thorough coverage of every plant in the area is essential for maximum effect. All leaves and stems must be thoroughly wet to the ground line. Nancy Loewenstein, Extension Specialist, School of Forestry and Wildlife Sciences, Auburn University; Amber C.

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.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 Nevertheless, when in doubt, avoid touching the unknown plant until you have obtained help to identify it.
