The 10:23 Challenge 2011

The 10:23 Challenge was a follow-up to the 'overdose' demonstration staged by the 10:23 Campaign in 2010. Protestors from 70 cities, across 30 countries, gathered to take megadoses of homeopathic remedies and make the simple statement: Homeopathy - There's Nothing In It.

The Challenge culminated on February 6th at the QED conference in Manchester, where 350 protesters simultaneously 'overdosed' on homeopathic Belladonna, in the biggest ever demonstration of its kind.
