The more recent symptoms are valuable as being the latest expression of the diseased condition, and must be covered by the remedy. This is especially true in acute diseases. This is so when another remedy is chosen; the last symptoms that appear must be the guide to it. Again, if a patient has been drugged by palliative medication, we must direct our antidotes principally against the drugs given last - for instance, against Quinine, Pulsatilla, Ipecac, etc.; against Iodine, Hepar; against Chloroform, Hyoscyam, etc. But this rule should not be applied too rigorously; it is best to give no medicine at all for a time.
* S. Kimball, in Homoeopathic Physician, June, 1895.
Functional symptoms of an affected organ are of much less value than symptoms which occur in other parts during the exercise of the function of that organ. Burning pain in the urethra, during or after micturition, is of little value in gonorrhoea, for it is usually present; but pain in the testicles, thighs, or abdomen during or after micturition, or symptoms of some other part not immediately concerned in that function, would be more important. So, also, pain in the stomach after eating, in indigestion, is not of as much value as vertigo or headache after eating would be in the same attack. Therefore, symptoms that affect the general organism are of more value than those that are functionally related to the organ affected. *
