"I think that EDM [a parliamentary motion Lucas signed on the issue] has been widely misconstrued," she insists.
"That EDM wasn't saying bring about homeopathy tomorrow. It was saying let's apply an evidence base to homoeopathy as we do to other medicines so I think the Green party remains pretty open."
Widespread evidence that homoeopathy does not work, or at least is only as effective as a placebo, does not seem to have convinced either Lucas or the Greens.
"We want to see a stronger evidence base," she insists. "Many people in homeopathic professions would say that the way the evidence is being used is not fair. It is not measuring like with like.
"It is not a major part of our policy," she adds, perhaps in anticipation of the criticism.
I ask if she's ever used it herself. She pauses.
"Yes I have."
