specificker
A homoeopathic practitioner who sought to ascertain the aetiologies of diseases, focusing on the symptoms most regularly associated with their diagnosis (to the exclusion of peripheral and occasional symptoms), and who, for their treatment, selected remedies (administered in more-or-less undiluted form) on the basis of their general physiological effects, ignoring incidental and side-effects.
obsolete
Those who arrogate to themselves the appellation of orthodox Hahnemannians have travelled far away, under the guidance of Gross, into the mystic regions of the 200th, 800th, and 10,000th dilutions, while the section, by the former styled specifickers, have gradually descended to the lowest numerals in the scale of dilutions until they have attained their ultima Thule in the Schmidian tinctures and first triturations.
Where it comes from
From specific (“specific remedy”) + -er, originally a calque of German Spezifiker, used by Samuel Hahnemann (1755–1843).
