Abstract

fetched live from OpenAlex

Abstract American pennyroyal, Hedeoma pulegioides (Linne) Per soon (Fam. Labiatae), is distributed from Canada to Florida and west to Nebraska (7). Pennyroyal has a long history of folk-medicine use as an aromatic stimulant, a carminative, a diaphoretic, an emmenagogue and, among Native Americans, a treatment for headache (7). The herb and oil of pennyroyal (also known as Mentha pulegium) are used in flea collars for cats and dogs (4 ). The oil contains ()-methone, ( +)-isomethone, and an hepatotoxic monoterpene, R( +)-pulegone, which depletes plasma and hepatic glutathione. Pulegone is metabolized by human liver cytochrome P-450s to menthofuran (vide supra), a proximate hepatotoxic metabolite of pulegone (3,4). Rats treated with pulegone develop severe hepatotoxicity (3,5); the nervous system appears not to have been examined. Ingestion of pennyroyal in herbal teas has resulted in severe and some times fatal poisoning (1,2,6); most cases have occurred in adult women who used pennyroyal as an abortifacient (4). Two infants developed hepatic and neurologic illness after ingestion of home-brewed mint tea (2). One infant developed hepatic dysfunction and severe epileptic encephalopathy. Fulminant liver failure with cerebral edema and necrosis developed in the second. Sera from both individuals

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
