 In November 2014 the Green Party stripped Browning of his natural health products portfolio, after he signed and shared an online petition supporting the use of homeopathy to treat Ebola virus disease.Party co-leader Metiria Turei described Browning's actions as "a mistake", and said that the portfolio change was designed to reassure the public that the Greens "take health issues seriously".Browning said he did not oppose homeopathy on a personal level.
