The sap of Giant Hogweed contains toxic chemicals. When these come into contact with the skin, they cause reddening of the skin, often followed by severe burns and blistering. The burns can last for several months and even once they have died down the skin can remain sensitive to light for many years.

To combat the growth of Giant Hogweed we would recommend first seaking specialist advice. However, the most common way of removal is via chemical control; this however can only be carried out during the growing season (March to August) in order to be effective.
