Hi all,

My understanding of provings was that they occurred using material doses of poisonous substances on healthy volunteers.

But the 6th edition mentions:


"The most recent observations have shown that medicinal substances, when taken in their crude state by the experimenter for the purpose of testing their peculiar effects, do not exhibit nearly the full amount of the powers that lie hidden in them which they do when they are taken for the same object in high dilutions potentized by proper trituration and succussion, by which simple operations the powers which in their crude state lay hidden, and, as it were, dormant, are developed and roused into activity to an incredible extent. In this manner we now find it best to investigate the medicinal powers even of such substances as are deemed weak, and the plan we adopt is to give to the experimenter, on an empty stomach, daily from four to six very small globules of the thirtieth potency of such a substance, moistened with a little water or dissolved in more or less water and thoroughly mixed, and let him continue this for several days."

Does this mean Hanhemann was advocating that the 30c potency should be proved on healthy volunteers, or on patients who were ill?
