Mystical Heart Collective: An In-Depth Review for Pop-Up Ayahuasca Retreats
Mystical Heart Collective was a US-run psychedelic integration coaching brand that held pop-up ayahuasca and San Pedro retreats in Olón, Ecuador and San Pancho, Mexico around 2021 and 2022, founded by Sinclair Fleetwood with co-facilitator John Steiner, according to directory listings and a 2022 podcast page. Against that, no curandero, program, price, screening or medical staff was ever published, no reviews exist, its website is now a parked domain, and its founder now runs plant medicine retreats in North Carolina that do not name the medicine, with a non-refundable $600 deposit.

🔍 Critical Notes
Who runs it. Sinclair Fleetwood founded the brand and its podcast; she says she spent two years in the Ecuadorian Andes working with ayahuasca and San Pedro and managed an unnamed retreat center there, and lists yoga and coaching certificates but no medical or clinical license, per her about page. Mystical Heart Collective LLC owns a US trademark filed in 2020, per Justia.
Screening and medical support. No medical questionnaire, contraindication list, medical staff, ceremony leaders or emergency protocol were published for the retreats, and no hospital distance can be given without a venue.
Successor. The founder now works under her own name from Asheville, North Carolina, running four-day “ceremonial plant medicine” retreats that do not name the medicine, per her retreats page. DMT, psilocybin and mescaline are Schedule I drugs under US federal law, per Wikipedia.
Legal context. Ecuador has no specific regulation of psychedelic ceremonies, per Expreso.
Status. No retreat dates under this name were found after early 2022, and the website now redirects to a parked page. The founder’s terms page still names the old brand.
Corrections to our earlier profile. Our earlier page said the brand was potentially closed and being monitored for rebranding; it has ended as a brand, and its founder now works under her own name in the US. It was never a fixed center in Ecuador. The International location fits its pop-up model. Our earlier grade was C; the grade is now C-.
🆘 Screening & Mental Health Risks
No contraindications are published. ICEERS notes that ayahuasca’s MAOI component makes it dangerous with SSRIs and other serotonergic drugs and that it is contraindicated for people prone to psychosis. Never stop a psychiatric medication to qualify for a ceremony without your prescriber’s guidance.
🧪 Brew Substance
Ayahuasca and San Pedro of undisclosed recipe and source. Ayahuasca combines the Banisteriopsis caapi vine with a DMT-containing leaf such as chacruna, as Erowid explains.
📍 Location, Setting & Style
- Setting: Beach towns in coastal Ecuador and Mexico.
- Rooms: No information.
- Style: Western-led retreats centered on psychedelic integration coaching.
Practical guidance: For the founder’s current retreats, ask which medicine is served and under what legal basis before paying a deposit.
Should You Book?
Not under this name. Before booking with the founder’s current retreats, ask in writing which medicine is served, who leads ceremonies, how guests are screened and what happens in an emergency. Read our guide to verifying retreat facilitators.
The Team & Story
The brand’s trademark was filed in 2020 and its retreats ran around 2021 and 2022. We did not independently verify anyone’s training.
Prep & Integration Tips
Before you go: Disclose every medication and condition in writing and plan any change with your own doctor. After you return: Arrange support from a qualified therapist at home. Our guide on how to research ayahuasca incidents can help you check any center.
