If you have a pet, you might be wondering if Henbane is poisonous to your pet. Yes, it is. The toxin in henbane is atropine, scopolamine (hyoscyamine), and l-hyoscyamine. The toxicity in henbane is highest in the roots, and lowest in the seeds, leaves, and stem with bark. A high concentration of atropine in Henbane leaves can cause dilated pupils, dry mouth, and even a rapid, irregular pulse in your pet. If you have a pet that is consuming Henbane, the first step is to contact your your veterinarian.
What is Henbane?
Henbane (Hyoscyamus niger) is a poisonous flowering plant that is used as a recreational drug. The chemical in henbane called hyoscyamine is a potent blocker of the neurotransmitter norepinephrine, a major regulator of heart, respiration, and intestinal activity. Henbane acts on the brain to inhibit sensory input, motor activity, memory, and concentration, producing an altered perception of the passage of time, reduced sense of pain, and an altered sense of reality.
