Poisonous Plants
Plenty of common wild plants can cause a rash, an upset stomach, or worse if eaten, and knowing the ones in your area is the point of a guide like this. Some, like poison ivy, cause trouble on contact; others are only dangerous if swallowed. Here are the poisonous and toxic plants in the Huck field guide, each with a safety note on what it does and how to recognise it.

What are the most dangerous plants to touch?
In North America the classic contact-rash plants are poison ivy, poison oak and poison sumac, which carry an oil called urushiol that blisters most people’s skin. Giant hogweed and wild parsnip can cause burns in sunlight. Learn these few by sight and you avoid most trouble.
How do I know if a wild plant is poisonous to eat?
Assume it is until you have identified it with certainty. Many toxic plants closely resemble edible ones, and a wrong guess can be serious, so never eat a wild plant on a hunch. Identify it first, check the safety note, and when in doubt leave it.
