Piers Gibbon

In Jungle Trip, Gibbon expresses his desire to try ayahuasca, having read so much about it. He flies to the Amazonian city of Iquitos, where he meets with an American expatriate named Alan Shoemaker. Shoemaker officiates Gibbon's first ayahuasca ceremony, as well as others involving the ingestion of tobacco juice and flogging with nettles.

To continue the quest, the crew employs wilderness guide Richard Fowler, who takes them further afield to experience something of the traditional medicine of the Matsés people. When they arrive, David Fleck (an anthropologist doing fieldwork with the Matsés) serves as translator. With the women and children looking on, the Matsés men administer a tobacco snuff called rapé, which is blown into the nostril through a hollow bone or other tube. Later, the men capture a frog that, although gentle and calm, secretes protective toxins, which the Matsés collect. After administering the poison through superficial burns, the men hunt and kill an armadillo.

But Gibbon wants to further his experience of ayahuasca. With the assistance of anthropologists David Fleck and Françoise Barbira Freedman, he meets with a healer (or curandero) called Don Guillermo, who in turn refers him to a more powerful healer, Don Demetrio. After the film crew leave, Gibbon stays with Don Demetrio for thirty days of ayahuasca drinking.

Near Don Demetrio's home, Gibbon collected a live plant to send to the Kew Gardens in London. There it was analysed and named for him.[7]

In each episode of The Witch Doctor Will See You Now (2011), Gibbon escorts two Americans to a different country to try traditional medicines alleged to treat various conditions.[8] His stated aim was to test the healing powers and credibility of people whom Western society sometimes calls "witch doctors".

Gibbon was the Master of Ceremonies for the University of Warwick graduation ceremonies in July 2022 and 2023.
