If you are sure of what plant poisoned you, you can make more educated decisions of how to treat it, especially if you have been affected by the same plant in the past. For example, if I were to get a rash from poison ivy, I would wash the area and use anti-itch cream because in my experience, that is what has treated the rash.

You can conduct some research for yourself regarding treatments for poison, but remember that you can’t always believe everything you read on the internet. When your health is at risk, it is always more beneficial to seek professional advice.
