The whole picture, in one breath

Think of chills that return on schedule: the intermittent fever with chills of the books, the anxiety and anguish of the paroxysm, the books' great remedy of the uninvited bedfellow — and the insect that shares every old bed. The bedbug's chill: that is Cimex.

The substance, in plain words

Cimex is prepared from the bedbug — the uninvited companion of every old bed, its bite genuinely irritating and its saliva a real subject of modern allergy research. The proving gave the insect the intermittent-chill portrait of the books' fever chapter.

Where the classical picture comes from

The uninvited bedfellow's proving gave the intermittent-chill portrait; Cimex became the classical remedy of the returning chill — the insect of every old bed serving the fever its bite seemed to announce.

The substance in real medicine Pharmacology

What this section is: the pharmacology and toxicology of the source substance. It is not clinical evidence that a homeopathic preparation of it treats any condition. What controlled trials do and do not show is set out on the Evidence page.

The bedbug's real modern career is entomological and immunological: its saliva is a genuine subject of allergy research, and its resurgence is a documented modern public-health story. The intermittent fevers it portrayed are diagnosed by test and treated; the insect's chemistry is real, its portrait's territory modern medicine's.

Look-alikes (how the classical authors told it apart)

RemedyLooks similar because…Tells it apart because…
CedronClockwork feversCedron's keep perfect time; Cimex's bring the anguish of the chill.
Aranea diademaPeriodicityAranea's is the periodic cold bones; Cimex's the intermittent chill with the anguish.
China officinalisPeriodicity and debilityChina's is the post-loss weakness; Cimex's the anguished chill itself.
Eupatorium perfoliatumChills and bone-achesEupatorium's chill breaks the bones before it sweats; Cimex's is the anguish with the chill.
Safety. Any returning fever needs diagnosis — malaria, still present in much of the world, is tested and treated, not timed.
