Herbalism, Citizen Science, and Ancestral Knowledge

Brainforest Café

About
Join Dennis McKenna in this insightful conversation with Rebecca Lazarou as they explore the urgent need to preserve ancestral medicinal plant knowledge, the role of ethnopharmacology, and how traditional herbal wisdom can be protected for future generations. Rebecca shares the story behind her PhD research on Cypriot medicinal plants and her mission to document at-risk ethnobotanical knowledge before it disappears. They also discuss citizen science, cultural heritage, biodiversity, and the connection between science and traditional healing.

IMPORTANT NOTICE:
Due to unforeseen circumstances the activities for Rebecca's event in
London has now shifted. The date and location will be the same, and it
will still be a highly educational event but it will now be a more
intimate home herbalism medicine making workshop.

Participants will learn all about medicinal plants, the medical system,
and will be making their own teas to take home with herbs focused on
mental health and stress. Rebecca will also talk about ethnobotany, have a
herbal tea bar, and all proceeds still go towards supporting her
research.

Rebecca Lazarou’s work is an ecology of different disciplines spanning across medical science, ethnopharmacology, herbalism, holistic healthcare, cannabis and psychedelics. She is also an activist, writer, speaker and herbal formulator.

She is currently a PhD candidate at Kew Gardens and UCL School of Pharmacy with a focus on ethnopharmacology and herbal medicines. She was the science and managing editor for the ESPD55 volume, is currently co-editor for education charity Herbal Reality and founded Laz The Plant Scientist to bring quality, sustainably sourced herbal medicines and education to people.

She is passionate about democratizing knowledge, and rekindling ethnobotany and herbalism from being marginalised disciplines to part of common knowledge again.

Ultimately her aim is to help nurture our relationship with nature through natural medicines, and support our species return back to Earth centred living. She is devoted to science to demystify these topics, but equally I am committed to rekindling the magic, awe and healing we find on our precious Earth.
