Chris Kilham and Zoe Helene


Zoe and her husband, ethnobotanist and Medicine Hunter Chris Kilham, work and travel together extensively, exploring remote regions of the globe, working to promote mind/body/spirit wellness, sustainable global trade, environmental protection and cultural preservation.

Cosmic Sister’s Psychedelic Feminism educational advocacy grants are supported in part by Medicine Hunter, which is our partner and primary sponsor.

“Psychedelics help to promote harmony and a profound sense of interconnectedness of all things,” said Chris Kilham, founder of Medicine Hunter. “And that understanding creates a certain obligation and responsibility to acknowledge and promote and maintain that understanding.”


The Ayahuasca Test Pilots are a collaboration of individuals who engage in the ceremonial practice of ayahuasca journeying with skilled shamans. Founded by Medicine Hunter Chris Kilham, our purpose is to journey for healing and to explore the spirit landscape, with dignity and respect for La Medicina.

Chris plays an essential role in Cosmic Sister's Psychedelic Feminism educational advocacy, which brings women’s voices to the forefront in the field of psychedelics and promotes intentional journeying with natural psychedelics in a safe, legal “set and setting.”

The Amazon rainforest is the greatest of all forests on earth, home to an estimated eighty-thousand higher plants, home to perhaps millions of types of insects, and a broad array of rapidly diminishing populations of rare and unusual animals. Zoe Helene and Chris Kilham are working along with many other dedicated people around the world to help save Earth's precious rainforests before they disappear.

In 2002 Zoe chose to transition from serving predominately conventional Americana brands to supporting the Natural Products Movement. As an independent she worked with top name brands and provided strategic consulting for The Organic Center, a non-profit organization providing scientific information proving the benefits of organics. It is during this time Zoe met Chris at an industry trade show.

This Medicine Hunter Related Media is a list of selected media events that Zoe Helene took part in and/or supported in the global sustainability work she does with her husband and partner, ethnobotanist and Medicine Hunter Chris Kilham. Helene often travels with media on Medicine Hunter expeditions, supporting journalists, photographers, correspondents and producers before during and after travel. She is sometimes featured in the story, sometimes mentioned, and other times simply supports from the behind the scene. All of this is part of the work, and media means getting the messages out there in the world.
