164     The power of medicines acting upon the infant through the milk of the mother or wet nurse is wonderfully helpful. Every disease in a child yields to the rightly chosen homœopathic medicines given in moderate doses to the nursing mother and so administered, is more easily and certainly utilized by these new world-citizens than is possible in later years. Since most infants usually have imparted to them psora through the milk of the nurse, if they do not already possess it through heredity from the mother, they may be at the same time protected antipsorically by means of the milk of the nurse rendered medicinally in this manner. But the case of mothers in their (first) pregnancy by means of a mild antipsoric treatment, especially with sulphur dynamizations prepared according to the directions in this edition (§ 270), is indispensable in order to destroy the psora—that producer of most chronic diseases—which is given them hereditarily; destroy it both within themselves and in the fœtus, thereby protecting posterity in advance. This is true of pregnant women thus treated; they have given birth to children usually more healthy and stronger, to the astonishment of everybody. A new confirmation of the great truth of the psora theory discovered by me.
