Before
Screening is mandatory
First-time participants complete a questionnaire and join an individual interview. Previous experience elsewhere does not replace this process.
The Sanctuary never tells anyone to stop medication or treatment. Questions about health conditions or possible interactions must be discussed with the responsible health professional and shared honestly with us.
During
Limited attendance and attentive guardians
We limit attendance so the team can organize the ceremony and support the group with care. Directors and guardians remain present throughout the work.
All guardians have taken first-aid training as part of the team’s ongoing preparation.
Ethical foundation
Nine guidelines for collective care
- Non-specialism: no one owns spiritual knowledge.
- Non-intervention: each person’s process is respected.
- Free will: each person has their own pace and makes their choices within the ceremony’s safety limits.
- Silent listening and presence are forms of care.
- Words are used carefully, without imposed interpretations or diagnoses.
- Spiritual humility recognizes mystery and the limits of what any one person can understand.
- Service and fellowship express responsibility for the group.
- Indigenous traditions are approached with ethics, gratitude and clear attribution.
- Autonomy and personal responsibility guide each participant’s choices.
After
Support does not end with the ceremony
Participants may contact the leadership team after an intense experience or when they need help finding the right kind of support.
Psychologists connected to the Sanctuary may offer an initial listening session within professional limits. The Sanctuary does not promise outcomes and does not replace clinical care.
Essential information
What are the main ayahuasca safety and contraindication considerations?
Assessment is individual and no short list is complete. Pregnancy or breastfeeding, significant or uncontrolled cardiovascular conditions, a personal history of psychosis or mania, acute emotional destabilization, epilepsy or seizures, and certain medications or substances may prevent participation or require professional assessment. All conditions and medication use must be disclosed. The Sanctuary never advises stopping treatment.
Can any ayahuasca ceremony be described as completely safe?
No ceremony can promise the absence of risk. A responsible ayahuasca ceremony reduces avoidable risk through honest screening, informed decisions, limited attendance, a prepared setting, attentive guardians and suitable professional or emergency referral when necessary.
