The Caya Shobo 12-day Ayahuasca Master Plant Dieta retreat is our recommended option for those who have worked with the medicine before.

This longer stay offers a deeper immersion into the sacred plant medicine traditions of Shipibo Amazonian shamanism. Experience the healing Icaros and meet the Maestros in their home environment – at a beautiful, conveniently located center just outside Iquitos, in the heart of Peru’s Amazon.

What is a ‘Master Plant Dieta’ ?

Ayahuasca is considered to be the “Grandmother" of the plant medicine world. Essentially there are thousands of potential plants, flowers and tree spirits under her guidance, and these plant spirits are which the Maestros can call upon to assist in the healing process for a client.

In the Amazonian Shipibo tradition, shamans are initiated and trained into the world of Ayahuasca healing only when they open ‘diet’. When a shaman has completed an isolation diet on a particular plant, is it considered to be part of their knowledge to draw upon.

Each Master Plant Dieta completed is akin to a Shaman reading a new book about a plant spirit. Apprentices in the Shipibo tradition are required to complete years of training before working with participants in ceremony.

Guests will be able to open the process of ‘Master Plant Dieta’ – considered a much more intensive journey with the plant spirits.

With 7* Ayahuasca ceremonies during a Caya Shobo 12-day Ayahuasca Master Plant Dieta Retreat, many of our participants find they experience powerful personal insights and a deep physical cleansing during these transformational ceremonies. With everything provided for you, you can relax and immerse yourself in the retreat experience, knowing that you are well supported and safe to explore the benefits of this ancient medicine tradition.

The Caya Shobo gardens are filled with local plants and flowers used for dieta
