Opposite action of high and low potencies.

In typical Calc carb children, it would cure diarrhoea only in high (200/1m ) potencies but could cure constipation only in 6th potency.i experiment in patients, found a similar peculiaritiy that Podophyllum high 200/1 m potency cured diarrhoea and is a fine remedy for constipation with whitish ( bileless ) stools in 6th potency.I remembered reading something like this in some book and found it in Hale's article.
Leave a side the theory, I have made very good use of this point in the following situations.
With Iodium 200/1m , I have added weight to lean and even emaciated boys and girls. And Iodium 2x and 3X are the best remedies to help in reducing obesity given 5 pills 3 times daily. Of course these patients are given the usual indicated high potencies of their constitutional remedies.
People having weakness, dizziness on sitting up or jaundice etc of Digitalis have been wonderfully cured by Digitalis high.30/200 when pulse was slow, and by 3X or 3 even 6th when pulse rate is fast.
In number of cases I have used Bry.200 to dry the phelgm and 6 th potency when there was too much dryness in the air passages or for similar action on the synovial fluid in the large joints like the knee joints.
Now it's Hahnemann who has explained the peculiar seemingly opposite symptoms appearing in the proving. He has called them primarily and secondary. But where a seeming secondary symptom appears first ( in later periods of proving ) he calls this alternating action. This does not depend upon the dose but We make use of this dual action for selecting a potency low or high. This is only possible in some situations, not for every remedy or every symptom .
Experience brought this idea into my practice. It is not antipathy, the indications in the patients being similar to those of the drug.
