Institutional description of symptoms, including severe disturbance of consciousness and breathing; used for present medical comparison.
Clinical practice guideline, “Background” and “History and Physical Examination”: muscarinic receptor antagonism and central/peripheral signs. Used for present scientific interpretation of belladonna toxicity.
International Chemical Safety Card: corrosive ingestion, acute symptoms and possible effects on calcium balance.
Journal of Clinical Pathology 20(3), pp.283–285. Original investigation of five patients following oxalic acid or ethylene-glycol poisoning; primary indexed abstract: pubmed.ncbi.nlm.nih.gov/5602563/. Used for later biochemical evidence, not attributed to 1864.
Original case report; renal biopsy showed tubular injury with refractile calcium oxalate crystals. The case does not establish that every exposure produces hypocalcaemia. Indexed full text was available; direct retrieval intermittently displayed a browser-verification page.
Case of Criminal Poisoning with Oxalic Acid, in Which Perforation of the Stomach Took Place by Henry Duncan Littlejohn by 
Codex 0 2026-10-31
Codex 0 2026-10-31 Practical Notes on Diagnosis, Prognosis, and Treatment in Cases of Delirium Tremens by Thomas Laycock by Codex 0 2026-10-31
Codex 0 2026-10-31Sections 4.1–4.5: indications, contraindications, renal function, electrolyte disturbances and interactions.
The Prescriber's Analysis of the British Pharmacopoeia by John Birkbeck Nevins (1864) by Codex 0 2026-10-31
Codex 0 2026-10-31Contemporary first-edition commentary, identified by Wellcome's 1864 catalogue record. Printed pages are three less than the zero-based PDF page index. Strengths and terminology are specific to 1864; some abbreviated numerical entries disagree with the detailed monographs and are not silently reconciled.
Second edition, John Churchill and Sons, 1865. Used for historical observations and the wet hydrated-peroxide procedure, not as authority to import later pharmacopoeial names.
Why is this medication prescribed?: modern cardiac indications.
Side effects: yellow-brown or red-brown urine.
Black stools and tongue with bismuth subsalicylate; this modern formulation is not equated with an 1864 recipe.
Patient management: acute exposure, supportive care and specialist consultation concerning chelation.
An official standard specifying the identity, preparation and quality of medicinal substances. An edition must be specified when interpreting historical prescriptions.
A corticosteroid is a steroid hormone of the adrenal cortex or a related synthetic compound. Effects on metabolism, immune signaling and salt balance differ among compounds. The broad class should not be treated as one uniform physiological action.
A uterotonic increases contraction or tone of the uterus. The term describes a physiological effect rather than one chemical class. Receptor-mediated stimulation and other routes can therefore produce related uterine responses.
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
