Okay so in my back courtyard there is a plant called poison parsnip. I read abundantly about the plant but nothing say aloud how deadly it is. I was freshly wondering has anyone ever gotten burned by this plant.??
Answers:    "Poison parsnip" is a term I've never hear before. Wild parsnip, Pastinaca sativa, is a weedy form of the garden parsnip. Like many plants surrounded by that family (Apiaceae or Umbelliferae) there are compounds that are photosensitizers when they drip on skin that after stays out in the sun for a bit.

Please be careful next to plants in this plant family -- within are a number of edible plants, and some, approaching poison hemlock, that are quite deadly. Do not ingest any plant contained by this family unless you're exceedingly sure of its identity.

And yes, I've got a nice defacement on one wrist from a drop of sap that somehow got under some latex gloves I be wearing while removing wild parsnip from a natural nouns. It blistered and peeled and was pretty uncomfortable for several weeks.
Poison Parsnip (also known as Wild Parsnip) looks similar to hemlock and is found in open out places along roadsides and in waste places throughout the United States and Canada.

Wild parsnip and poison hemlock are non-native plants that originate in Europe. The edible roots of frantic parsnip (therefore in answer to part of your quiz: not deadly at all)..are still eaten today and be, in fact, consumed within ancient Greece and Rome... while poison hemlock (which IS deadly) was used as a poison, most notably specified as the poison that killed Socrates.
HOWEVER:
This plant produces a substance that causes severe blistering and discoloration after person exposed to sunlight -- a condition known as photodermatitis. That is, when the skin comes in contact near this plant's juice and then is exposed to UV street light, a severe burn develops.

Brushing bare skin across a flower top will almost certainly lift up some very nasty blisters that can blemish like a burn. Another discouraging thought is that the seeds may fabrication dormant in the ground for 6 to 8 years before sprouting. And.Everyone can find burned by wild parsnip. Unlike poison ivy, you don't need to be sensitized by a prior exposure. However, rainy parsnip is only dangerous when the liquid from broken leaves or stems gets on your skin -- therefore, you can touch and brush against the undamaged plant minus any danger.

Burns from wild parsnip are usually misdiagnosed as poison ivy. In mild cases, artificial skin reddens and feels sunburned. In more severe cases, the skin reddens first, then blisters. The blisters appear a sunshine or two after sun exposure.

Wild parsnip's burn is usually less irritating than poison ivy's itch. Generally, wild parsnip cause a modest burning pain for a day or two, and next the worst is over whereas the itch and discomfort from poison ivy drives people crazy for a long time.

So, when it comes to the second part of your request for information, I shall, simply answer as Socrates would; "True knowledge exists in knowing that you know zilch; and in knowing that you know nothing, that make you smartest of all"

Good luck and happy gardening!!
