If you have ever had a cutaneous eruption with ampoules and itching after coming into contact with a plant, it is possible that it has crossed its path with the poisonous Zumaque. This dangerous plant, scientifically known as toxicodendron Vernix, is usually found in humid areas of North America. In this article, we will explore the aspect of poisonous Zumaque and deepen the symptoms and treatment options for its eruption.

1. Identification of poisonous zumaque:

  1. Height: poisonous zumaque usually grows as a bush or small tree, reaching a height of up to 6 meters. Its long and thin stems are covered with small pale color bumps, known as slow them.
  2. Leaves: Each stem has an odd number of leaves, normally from 7 to 13 bolts organized in pairs. Folioli are oval shape with pointed ends and smooth edges. They have a lustrous appearance and their color can vary from bright green to an intense red tone in autumn.
  3. Bays: At the end of summer and in autumn, poisonous zumaque produces clusters of small greenish white berries. These berries, often called dupas, contain a resin called Urushiol, responsible for causing an allergic reaction in humans.

Note: It is important to remember that some plants may resemble poisonous Zumaque, but they are harmless. To be sure, it is advisable to consult a reliable field guide or ask for advice from a professional before trying direct contact with any unknown plant.

2. Symptoms and eruption treatment:

  • Appearance of the eruption: when coming into contact with the poisonous Zumaque, the skin can develop a red eruption with itching, which usually appears within 12 to 72 hours. The eruption usually occurs in the form of veins or patches of inflamed and blistering skin.
  • Duration: Poisonous Zumaque eruptions can last from 1 to 3 weeks, depending on the individual immune response. Starting vigorously the eruption can cause bacterial infections and prolong the healing process.
  • Treatment: To relieve the symptoms of an eruption by poisonous Zumaque, it is recommended to clean the affected area with soft soap and cold water. The calamine or hydrocortisone cream application application can help reduce itching and inflammation. In severe cases, a healthcare professional can prescribe oral or corticosteroid antihistamines.

IMPORTANT: If you experience difficulty breathing, face or mouth swelling, or if the eruption covers an extensive area of your body, look for immediate medical attention, since it could indicate a severe allergic reaction.

If you familiarize the appearance of poisonous Zumaque and understand the symptoms it can cause, you can take the necessary precautions to avoid contact and seek adequate treatment if necessary.

Poison Sumac Pictures: Identifying the Toxic Plant

Images for the identification of poisonous zumaque

To effectively recognize poisonous zumaque, visual aids such as images can be very useful. The poisonous zumaque is characterized by its distinctive appearance, in which each part of the plant has unique features. Through the study of image of the poisonous Zumaque, people can familiarize themselves with their key characteristics, which facilitates their identification and avoid it in nature.

Use of the UL, OL and Table blocks for a clear representation of the information

Among the various HTML labels available, the UL blocks (disorderly list), OL (orderly list) and table can be effective tools to present the information clearly. For example, a messy list (UL) can be used to detail the main characteristics of poisonous zumaque, such as its leaves, berries, stems and the environment in which it grows. On the other hand, an orderly list (OL) can be used to describe the steps to follow to treat and control the rashes caused by poisonous zumaque. In addition, a table can be used to compare the poisonous zumaque with simila r-looking plants, highlighting the distinctive characteristics that differentiate it.

It is important to remember: although the images are useful to identify the poisonous Zumaque, it is always recommended to consult a medical professional, such as a dermatologist or allergologist, to obtain an accurate diagnosis and adequate orientation in case of exposure or reaction.

What Does Poison Sumac Look Like?


  • The poisonous zumaque plant is a deciduous bush or a small tree that usually grows in wet areas such as swamps, swamps and linked swamps.
  • It can reach a height of up to 6 meters and is recognized by its thin stems and its smooth and glabrous leaves.
  • The leaves are arranged in pairs and consist from seven to thirteen leaflets. Each leaflet has a pointed oval shape with dental edges.
  • Unlike poison ivy and poisonous oak, which have three leaflets, poisonous zumaque has a more complex foliar structure.
  • The leaves are of a vibrant green during the spring and summer months, but are transformed into vibrant red, oranges and yellow tones during autumn.

Note: It is essential to be cautious when we meet the poisonous Zumaque, since even indirect contact with the oil or sap of the plant can trigger an allergic reaction.


  1. Look for the presence of berries on the poisonous Zumaque plant. The berries are small, round and green, and become whitish or beige gray color when they mature.
  2. Observe the plant stem, which contains reddish-brown or gray-negral points, known as lenticels.
  3. Pay attention to the disposal of the leaves, which grow in a pinnate pattern, with pairs of folioli united to a central stem.
  4. Look at the most common habitat of poisonous zumaque: wet areas such as swamps, marshes and bogs.

Differentiating Poison Sumac from Harmless Plants

Appearance: poisonous zumaque can often be confused with harmless plants due to the similarities of its appearance. However, there are notable differences that can help differentiate it. The poisonous Zumaque usually grows in the form of a bush or small tree, with a height that ranges between 5 and 20 feet. It is usually found in humid or swampy areas, with clusters of sheets arranged in the form of a pen. The leaves appear in pairs, with a single leaflet located at the end. Unlike the harmless plants, such as the zuma horn zumaque or the smooth zumaque, the leaf of the poisonous zumaque have smooth and bright surfaces, which makes them stand out in comparison.

Important information:

  • The poisonous zumaque has leaves arranged in pairs, with a single leaflet at the end.
  • The bladder zumaque leaves have a smooth and bright surface.
  • It usually grows as a bush or small tree in humid or swampy areas.
  • The clusters of leaves look like feathers.

Coloring: Another characteristic that differentiates poisonous zumaque from harmless plants is their distinctive coloration. While several plants can show a green foliage, the poisonous Zumaque stands out for its stems of a vibrant red. These red stems extend from the branches and serve as a visual signal when trying to differentiate the plant from their harmless counterparts. It is essential to keep in mind that, during certain stations, poisonous zumaque can undergo color changes, with the leaves making oranges or yellow. However, regardless of seasonal variations, the presence of red stems remains a constant identifier of this allergenic plant.

By knowing the distinctive characteristics of poison sumac, it becomes easier to differentiate it from other harmless plants. Recognizing leaf arrangement, texture, stem color, and overall appearance can help prevent accidental exposure to this highly allergenic plant. It is crucial to remember to always use caution when encountering unfamiliar vegetation, especially in wet or swampy areas where poison sumac often thrives.

The Distinguishing Characteristics of Poison Sumac

Leaf Arrangement: One of the key characteristics that distinguishes poison sumac from other toxic plants is the unique arrangement of its leaves. Instead of having leaves arranged alternately or in groups of three, poison sumac leaves are arranged in pairs along the stem, with a single leaf at the end. This pattern, known as the “pinnate” leaf arrangement, helps identify poison sumac in its natural habitat.

Note: It is crucial to avoid touching or coming into contact with poison sumac leaves, as they contain a powerful irritant called urushiol that can trigger an allergic reaction in susceptible people.

Leaf Structure: Another distinctive feature of poison sumac lies in the structure of its leaves. Each leaf is made up of 7 to 13 glossy leaflets that are pointed at both ends. The leaflets are arranged in pairs along a central stem, and their smooth margins lack the striations or notches found on harmless plants. Recognizing these characteristics of the leaves is essential to avoid accidental contact and subsequent allergic reactions.

  • Leaf arrangement: pinnate
  • Number of leaflets: From 7 to 13
  • Blade shape: pointed at both ends
  • Leaflet margins: smooth, without grooves or notches

Coloration: The coloration of poison sumac leaves can also help with identification. The leaves typically display a vibrant green hue during the spring and summer months, but as the season changes, they change to stunning shades of red, orange, and yellow in the fall. This fall transformation can make poison sumac plants stand out and be easier to recognize.

Caution: It is important to note that even when poison sumac leaves change color and fall off during the winter, urushiol oil may still be active in the branches and stems, causing possible allergic reactions.
