Hi this is Dr. Gabby. Do you mean Lamium amplexicanule (henbit or dead nettle)??? Was it in ingested? If so how much and how long ago?
Ok I am not a botanist so I am not sure if there are different species of Lamium.
The Lamium amplexicanule should only cause gastrointestinal upset. I do not think it should make her so sleepy or lethargic.
You can always call ASPCA poison control. They do charge $65 to use their service
