==Special Precautions of Persian Hogweed==
* Contact with the plant’s sap, if exposed to sunlight, can cause severe skin burns. The person will experience itching, redness, eczema, and stinging. * The sap induces sensitivity to sunlight.
* Persian hogweed has a tendency to suffocate out all other native plants and wildlife, causing significant ecological damage, particularly in Natura 2000 sites.
* It also has a major economic impact due to its erosive effects and impaired drainage along river courses.
