Poison oak and poison ivy, along with poison sumac all belong to the cashew family, Anacardiaceae. All three contain an oil that actually is a resin called urushiol that causes an allergic reaction (contact dermatitis) when it comes into direct contact with the skin of most people. Urushiol can also be transferred from other people, dogs and other pets, and clothing, tools or garden gloves if you touch them where they have the oils holding the resin on them.

Poison oak and poison Ivy are similar in appearance in that they each have a 3-leaf pattern. Poison Ivy grows as a shrub, bush or vine. The older vines, even if they have no leaves on them, can still hold resins. So, avoid touching older vines that look like they have "hairs" (aerial rootlets) on them. The stems attached to the leaves when younger often appear red. They also contain the urushiol. The ivy blooms in early spring. Once the flowers are pollinated, they produce small green berries that turn a creamy white in autumn.

Poison oak grows as a bush. The leaves of western poison oak may resemble oak tree leaves. Poison oak tends to be more prominent growing in the western half of the US, where as poison ivy is commonly found growing east of the Mississippi, and along most of the eastern and southern tier coastal regions and inland in most arboreal forests.

Treating poison ivy:

A less known "cure" for poison ivy is the "juice" of rhubarb stems. Like when using aloe vera, you break open the stalk and rub the viscous sap onto the area of the rash. It was suggested by an old Indiana farmer and, having used it (and nearly every commercial product and home remedy known to man) to stop the itch and dry up the rash from poison ivy, it is the best remedy found. It cools, soothes, stops the itch immediately, and then dries up the rash after only one or two applications.

How do you tell the difference between a poison ivy rash a shingles rash?

Poison Ivy can be spread to multiple locations while shingles will follow limited individual nerve paths on one side of the body. Additionally, shingles is very painful. Poison Ivy rash can sometimes be dotted trails along the leg if one walked through it. Inspect your entire body for multiple rashes from cross contamination to distinguish the two.


How can you tell you have poison ivy?

Poison ivy can cause a red, itchy rash with bumps or blisters. The rash often appears in streaks or patches where the plant's leaves brushed against the skin. If you suspect you have come in contact with poison ivy, wash the affected area with soap and water as soon as possible and seek medical attention if the rash is severe.


Does Shingles stay inward and never break out My husband is having pain under left rib and down side. Ct scan did not show any problem. Pain no better..no breaking out Is this like shingles?

Shingles develop in 3 stages. First, a deep pain as if caused by injury, but you were not injured. Second, stabbing pain which comes and goes. This kind of pain is specific to shingles, very unlike throbing pain which is continuous. If you take medication early you can stop the progress of the illness, otherwise blisters break out.


Is poison ivy a bacteria?

No. It is a plant; a flowering vine which is toxic and causes a severe rash when it touches the skin. Bacteria are microscopic organisms, and they can cause problems too, but they are different from poison ivy.


Can you sleep in the same bed with someone who has shingles?

Sure, you can sleep in the same bed as someone with shingles, as it is not a highly contagious disease. However, it's best to avoid direct contact with the rash to lower the risk of spreading the virus. So, cuddle up at your own risk, but maybe keep your distance from their rash.

How do you tell the difference between a wild parsnip rash and poison ivy rash?

Wild parsnip rash typically appears as a burning or stinging sensation followed by a blistering, red rash, often accompanied by dark brown or purplish discoloration. This reaction usually occurs after skin exposure to the plant's sap and is exacerbated by sunlight. In contrast, poison ivy rash presents as itchy, red, and raised blisters that may appear in streaks or patches, typically developing 12 to 72 hours after contact. The key difference lies in the timing and appearance; wild parsnip is sun-sensitive and can cause skin discoloration, while poison ivy causes a more localized, itchy reaction.

Can shingles be spread through skin contact?

Shingles is an outbreak of the chicken pox virus that causes a rash on the skin. But before the rash shows up, and after the rash is gone, the virus affects the nerves leading to the skin. Right before the rash shows up, a person affected by shingles might feel an itchy, burny pain in that area. After the rash is gone, the patient might have pain or discomfort in that area for some time -- again, related to the nerve involvement and not the skin rash itself. So, to be precise, shingles always develops "under the skin." The skin symptoms make it easiest to diagnose, but it's not the skin symptoms that cause the greatest aggravation with shingles.
