How complete this information is
The safety information on this page is partial. Where a source covers a point, it is shown; where none does, the page says so.

Toxic to pets
No ASPCA entry found.

Cats, dogs and horses: not found on the ASPCA lists as far as we read; that is not a clearance, so no verdict is given. People, skin contact: the hairs on leaves and stems cause an intense burning and itching sensation lasting a few minutes (NC State, which rates the plant low severity). Nebraska Extension says the hairs carry formic acid, histamine, acetylcholine, serotonin and other compounds, and advises gloves, a long-sleeved shirt and long trousers when harvesting nettle.

PlotAndPetal cannot tell you whether a plant you found can be eaten. Only someone who can see the plant can identify it.

Poison control

If someone has collapsed, cannot be woken, is having a seizure or has trouble breathing, call 911 now. For any other possible poisoning, call Poison Help: 1-800-222-1222.
