Characteristics
Cr. k. s. was introduced into hom┼Уopathic practice some years ago by Dr. Mersch, of Brussels, and in my experience it is by far the most valuable remedy for hay fever that we possess. I use it on Dr. Mersch's indications in the 6x trituration and downwards. Because it sometimes succeeds in the 3x, and even the 1x, when higher numbers fail. I generally give eight grains of the 5x to begin with, three or four times a day. There is no proving that I am acquainted with, but it can be used on general indications for coughs and catarrhs which its constituents will readily suggest.
