Citando:
"WHAT IS GIANT HOGWEED?
Chemicals found in the sap of giant hogweed (Heracleum mante-gazzianum) can cause photodermatitis or photosensitivity, where the skin becomes very sensitive to sunlight.

Blistering, pigmentation and scars may result, according to the Royal Horticultural Society.

Giant hogweed can often be seen in gardens and allotments, from spring to autumn, adjacent to infested woodland, heathland or common land."
