(The following is from a letter of Dr. E. M. Hale):
Some time ago I received a letter from Dr. F. S. Smith, of Lock Haven,
Pa., in which, referring to _Chionanthus_, he says:
"For the first time to-day I read your article on _Chionanthus_ in the
last edition of your Materia Medica of 'New Remedies.' I have been using
this drug for over two years, as a specific for so-called sick headache.
It has done wonders for me in that disease. I had been a victim from
early childhood, and have suffered terribly. I have not had an attack
for two years. If I am threatened, a few drops, timely taken, dissipates
it at once.
"Dr. B., a dentist, aged 35, dark complexion, a victim to sick headache,
had an attack on an average once in three weeks. Since taking
_Chionanthus_, has not had more than two or three attacks in over two
years, and then owing to a neglect to take the medicine. I have failed
in but one case, and that was a menstrual sick headache.
"I prescribe it as follows: In cases of habitual sick headache, 5 gtts.
of the 2x dil. three times a day for a week, then twice a day for a
week, then once a day for a week, after which the patient only takes it
when symptoms of the attack show themselves. I regard it almost a
specific."
(_Chionanthus_ is also, by some physicians, regarded as a
specific in jaundice, either acute or chronic, and the
proving seems to justify the belief.)
