Sosnowski's hogweed: A toxic plant menace revealed
Sosnowski's hogweed is one of the most dangerous plants. Even brief contact with the skin can cause severe burns, and in extreme cases, it can even lead to death. It grows wild in fields, meadows, ditches, and near forests.
This is the look of "Stalin's revenge"
Sosnowski's hogweed, colloquially known as "Stalin's revenge," was brought to the US in the 1950s as a fodder plant. However, it quickly became apparent that it poses a considerable threat to people and animals instead of being beneficial. Its aggressive spread has led to its classification today as an invasive species, prohibited from being cultivated and disseminated.
The plant blooms in June and July and can grow up to 16 feet tall. It has a thick, hollow stem with purple spots, large, sprawling leaves, and white flowers gathered in massive umbels that resemble dill but are much larger. Sosnowski's hogweed releases toxic substances—furanocoumarins—that, when in contact with skin and sunlight, cause serious reactions.
Burns, blisters, scars: symptoms of contact with the plant
The most significant danger associated with Sosnowski's hogweed is its phototoxic effect. When toxins from the plant come into contact with the skin and are then exposed to UV rays, they cause a strong chemical reaction:
- Second-degree and even third-degree burns
- The formation of painful blisters and wounds
- Discoloration and scars that can last for months
- Itching, burning, and swelling
- In severe cases, fever, headaches, and nausea
In people who are allergic, children, or seniors, it can even lead to anaphylactic shock or respiratory complications after inhaling the plant's fumes. In extreme cases, it can even be fatal.
What to do after contact with Sosnowski's hogweed?
A skin reaction may appear even after a few hours, so if you suspect contact with the plant, do not wait:
- Immediately wash the skin with soap and water.
- Avoid sunlight for at least 48 hours.
- Consult a doctor, especially if blisters, fever, or shortness of breath occur.
In cases of severe burns, hospitalization and long-term wound treatment may be necessary.
Why is Sosnowski's hogweed such a threat?
Hogweed is dangerous because of its ease of spread and the lack of public awareness. The plant appears in recreational areas, near rivers, roads, and playgrounds, and its appearance does not warn of danger. Many people, especially children, unknowingly touch the leaves or approach the stem, which is enough to cause burns.
Additionally, hogweed is very difficult to combat—its seeds remain viable in the soil for years, and each mature plant produces tens of thousands of seeds.
