Time to Eat Earth Again! From Edible Earth to Medicinal Minerals: Rethinking Our Relationship with Soil

This workshop explores several key questions: What lies behind the tradition of eating earth? Where does edible soil come from? What are its potential benefits and risks? And more broadly, how do humans interact with our environment and with non-human life?

Everyone is welcome to attend this in-person workshop. Registration is required as seating is limited.

The Workshop

Time to eat earth again! - But this time, it’s not out of financial hardship at the end of the month—it’s to explore the wisdom that has evolved over millennia. Humans and animals have eaten earth for thousands of years, for various reasons such as cultural customs, nutritional supplementation, healing, or psychological needs. In fact, in Traditional Chinese Medicine, certain minerals are considered medicinal materials, many of which originate from the soil. After specific processing, these earth-derived substances are used to treat a wide range of diseases.

This workshop explores several key questions: 

  • What lies behind the tradition of eating earth?
  • Where does edible soil come from? 
  • What are its potential benefits and risks? 
  • And more broadly, how do humans interact with our environment and with non-human life?

This workshop invites artist Dr masharu, founder of the Museum of Edible Earth in Amsterdam, and Prof. Winder W.T. Chang, Chair of Taiwan Studies at Leiden University, to engage in a cross-disciplinary conversation. Together, they will discuss the significance of soil and Chinese medicine in human life. Participants will also have the opportunity to taste selected earth samples and Chinese medicinal minerals, inviting reflection on our deep and complex relationship with the Earth.
