Oni Shobo: An In-Depth Review for Ayahuasca Retreats near Iquitos, Loreto, Peru

Oni Shobo is a jungle ayahuasca center reached by boat from Iquitos, Peru, run under the Amazon Green Ecolodge brand by Peruvian guide Jorge Arias and Czech pharmacist Věra Nápravníková, with a Czech partner company organizing group trips, that in 2016 sold six and 13-night programs with ayahuasca, kambo, plant baths and dieta for $750 and $1,500, per its 2016 blog. Guests in 2016 praised its Shipibo curandera, Celestina. Against that, a 2017 review describes disorganized ceremonies and an unexplained change of healer, no screening, contraindication rules, medical staff or emergency plan were found despite kambo being included, no legal entity is shown, and there is no dated activity after 2017.

🎯 At a Glance

• Locations: A tambo camp “well away from Iquitos but easily reachable by boat” near a San Pedro community and the Aucacocha lagoon, Loreto, Peru; no GPS is published.
• Approach: Ayahuasca ceremonies led by a Shipibo curandera, later reportedly a Murui coca healer, with kambo, rapé, mud and plant baths, steam and jungle excursions.
• Suitable For: No one until current operation can be confirmed. Not suitable for people taking antidepressants or with heart or psychiatric conditions.
• Costs: In 2016, $750 for six nights and $1,500 for 13 nights, with airport pickup; current prices and refund terms are not published.
• Overall Assessment: Affordable past programs and a well-reviewed healer, offset by no published safeguards for kambo or ayahuasca, a critical staffing report and no sign of activity since 2017. Directory evaluation: C-.

💬 What Guests Are Saying

An unclaimed AyaAdvisors listing shows 4.0 from four reviews from June 2016 to February 2017, three praising Celestina and a personal approach. The one-star review in February 2017 says the center was disorganized, the owner worked on a laptop during a ceremony, a heavily pregnant facilitator was the only staff present, and the healer was replaced without explanation (unverified). If you have attended, we encourage you to share your experience through our submission form.

🚩 Incident Report

We searched review platforms and English and Spanish-language news for reports involving Oni Shobo, Amazon Green Ecolodge, Jorge Arias and Věra Nápravníková.

• Deaths and serious injuries: None found. Ayahuasca-related deaths reported around Iquitos in 2015 and 2025 occurred at other centers.
• Sexual misconduct: No allegations found.
• Theft and fraud: None found.
• Legal action: None found.

The healers are known by first name only and were not searched individually, so this absence offers limited assurance.

If you have experienced or witnessed an incident with this center, please report it confidentially.

🔍 Critical Notes

Who runs it. Arias says he has worked in tourism since 1997, and Nápravníková sells plant preparations; the Czech partner SAGRAVITA, co-founded by a physician, organized 14-day group trips, per its partner page. No Peruvian company was found. It is a different center from Ayahuasca Onixobo.

Screening and medical support. No medical questionnaire, contraindication list, medical staff or emergency plan was found, including for kambo. The owner is a pharmacist, not a clinician. The boat time to Iquitos hospitals is not published.

Status. Probably dormant or closed; the last dated programs ran in April 2017, though a Czech partner page still names it as its venue.

Legal context. Peru declared traditional ayahuasca knowledge and use national cultural heritage in 2008, per Andina, and has no licensing regime for retreats, per ICEERS.

🆘 Screening & Mental Health Risks

Kambo adds its own risks; ask for written screening for both medicines. 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 prepared by the center’s healers; its source is not published. Ayahuasca combines the Banisteriopsis caapi vine with a DMT-containing leaf, as Erowid explains.

📍 Location, Setting & Style

• Setting: Hot lowland rainforest reached by boat from Iquitos.
• Rooms: Tambos and bungalows with private bathrooms and mosquito nets.
• Style: Small-group ceremonies with a strict dieta.

Practical guidance: Fly to Iquitos (IQT); past guests were met at the airport.

Should You Book?

Not until current operation can be confirmed. Ask in writing who leads the ceremonies now, the price and refund terms, the screening rules for ayahuasca and kambo, who on site is trained in first aid, and the evacuation plan and hospital route. Read our guide to verifying retreat facilitators.

The Team & Story

Oni Shobo presented itself as a Peruvian-Czech shamanic center pairing jungle medicine with natural health programs. 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.
