Reassess the case through careful observation again.
Look at what has changed after a remedy you gave that has caused an effect. The disappearance of symptoms, the increase or aggravation of symptoms, the amelioration of symptoms, and the order of the symptoms are all changes to be studied.
The patient doesn't always know if he is better or worse. Look at the symptoms. Make sure that match what the patient is saying.
Deep-seated disease can be palliated. Look at the depth of
action on the symptoms. The direction of cure is a sufficient observation to
make a judgment if cure is progressing. - Kent
