Organon §23

Antipathic treatment: Persistent disease symptoms are made worse by the opposite medicinal symptoms of antipathic medicines.

However, every pure experience and every exact experiment persuades us that persistent disease symptoms are so little lifted and annihilated by the symptoms of the medicine that oppose the disease symptoms (in the antipathic, enantiopathic or palliative method) that, after short-lasting apparent relief, the disease symptoms break forth again, only in an all-the-more strengthened degree, and they obviously worsen (see §58-§62, §69).
