Printed medical books multiply regimens and herbals after the 1450s press demonstration
From the 1470s printed medical books and herbals multiplied regimens that had been expensive in manuscript. In the causal graph this event strengthens Health-System Capacity, a driver that strengthens Hospital beds (per 1,000 people) — an improving welfare path.
Read the full account
From the 1470s printed medical books and herbals multiplied regimens that had been expensive in manuscript. This Fact stores that health-knowledge access path as later print, not as a Gutenberg clinic.
Context
Reprint can freeze error as easily as freeze a good recipe. Confidence stays medium on outcomes. The path is still a documented use of the press.
Johannes Gutenberg is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.
Why it matters
Health-knowledge path. Medium confidence on patient outcomes; high that medical titles were printed.
A herbal is not a field hospital. Keep the lag.
Who was responsible

What the sources establish
Internet Archive early medical prints and Britannica’s Gutenberg/print frame independently show medical incunabula as a press genre.
Established: printed medical/herbal books in the incunabula decades. Not established: that Gutenberg authored a herbal, or a mortality series.
