<p> Ritual is a cultural-psychological technology that facilitates transitions by establishing safety, trust, and shared meaning. In psychedelic therapy, ritual remains underdeveloped despite the heightened vulnerability and suggestibility inherent in non-ordinary states. Without clear frameworks, ritual applications can become prescriptive or ethically problematic—particularly when elements are borrowed from Indigenous or lineage-based traditions without established agreements and relational accountability. We draw on scoping methods to support a theory-building integrative synthesis of interdisciplinary literature, moving beyond specific ceremonial forms to identify the core functions of ritual action within clinical contexts. Ritual operates as a relational “organizing container” that stabilizes the therapeutic process by regulating the nervous system, orienting patient attention, and anchoring meaning through predictable sequencing and symbolic framing. We propose a principle-informed framework that translates these functions into consent-based, culturally humble, and autonomy-protective clinical practice. By shifting from prescribed techniques to a co‑created process, clinicians can use ritual as a stable anchor across preparation, dosing, and integration. This principle‑based approach supports flexible, relational care that honours cultural context, participant agency, and situated meaning‑making.</p>
