Spring Grove Hospital and Research Center appears in the book as an institutional site associated with psychedelic research. Its significance in the available account is indicated by repeated references to its facilities, its place in the continuation of research, and the protocols connected with its work; the evidence does not identify particular studies or researchers there.

Research Site

The book’s index associates Spring Grove’s facilities with several discussions of psychedelic research, pointing to pages 52, 56–59, and 218. These references establish the center as a recurring location in the research history, rather than a passing mention, but do not specify the studies or treatments represented in each passage.

Continuity of Research

The book’s chronology names the continuation of psychedelic research at Spring Grove as a distinct development. This places the center within an account in which research persisted across different periods. The available evidence supports that role, but does not provide the dates, institutional circumstances, or individual contributions needed to describe the continuation in greater detail.

Protocols and Institutional Role

The index also links Spring Grove with structured approaches and protocols. Together, these references present the site not only as a research facility but as a setting associated with organized methods of practice. The source material does not specify what those protocols entailed, so the center’s documented significance here remains institutional: it is a recurring location in the book’s record of psychedelic research and its continuation.
