RE: The fascinating phototoxic effect of giant hogweed

in #health7 years ago

good article. it's not harmless during the night. if you touch it ANYTIME you can suffer the photoxic effects. they are very invasive and difficult to remove. where I live in East London they have resorted to using very toxic herbicides to kill them off. My advice is to stay well away from them and where we live stay away from the toxic areas where they are being treated with glyphosates.

Thank you!

You're right! It's not harmless - during the night there is no ultraviolet light coming from the sun that causes the symptoms but they can appear on the next day and also from artificial ultraviolet light.

awful stuff. I once touched a phototoxic plant in a garden, not knowing it was. the back of my hand went red in sunlight for the next couple of weeks.. I'm not sure what the long term effects are. not to be confused with COWSLIP.. a harmless and similar looking (smaller) plant
