The manuscript’s complete bibliography, connected to the inquiry.

These 48 entries reproduce the bibliography of Preprint v1.1. Source-type labels are a guide to browsing, not a ranking of evidence. Controlled studies, surveys, first-person reports, traditions, and cultural comparisons do different jobs in the argument.

External links lead to DOI records, source pages, publishers, or authors; some require payment or institutional access. A catalogue link identifies a work, not verification of every claim in it. Salviabibel is one author’s longitudinal corpus. Anesthesia and sleep studies are comparators, not direct tests of Salvia.
