Unintentional ingestion of black henbane: two case reports
Bibliographic record
Abstract
Black henbane (Hyoscyamus niger) is a member of the nightshade family and an invasive species that grows world-wide, including in Canada. Black henbane is toxic due to its tropane alkaloid contents: hyoscyamine, scopolamine (hyoscine), and atropine. We present two cases of unintentional, acute henbane poisoning. A 65-year-old woman and her 71-year-old husband presented to the emergency department with tachycardia, confusion, hallucinations, and urinary retention after eating a plant thought to be a parsnip from their garden, later identified by family as black henbane. During admission, the woman developed an asymptomatic new left bundle branch block with no other signs of ischemia. Both patients were managed supportively; their toxidromes resolved within 36-48 hours. These cases illustrate the rapid antimuscarinic effects associated with black henbane poisoning. This is the first report describing a new left bundle branch block in the context of black henbane poisoning. However, no published reports of sodium channel activity with any of the constituents was found. Increased public information is needed to educate individuals on the recognition of these mimic plants, as well as the dangers of ingestion, given their ubiquity in private gardens.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
