Hi, Deborah, If any ensemble of informed, willing human volunteers participated in the hypothetical experiment, some would exhibit herxing and some would not. A statistical treatment of the outcome (e.g. perhaps a contingency table test) may allow an inference to be drawn on the question of presence or absence of silver in the blood. This would be an ethical approach, or at least more ethical than a controlled experiment on a single human. And lab animals would be spared.
Thanks for your thoughtful critique. Best regards, Matthew
