Spigelia anthelmia

Made from pinkroot — the American worm-flower whose genuine anthelmintic chemistry made it official, and the classical remedy of the left-sided, stitching, heart-pained head.

The whole picture, in one breath

Think of a left-sided agony in waves: stitching, tearing pains over the left eye and orbit, worsening with every beat of the pulse, spreading from the head to the neck and arm, worse for motion, touch and noise, in a person of nervous temperament. The left-sided stitching head: that is Spigelia.

The substance, in plain words

Pinkroot is the American worm-flower — its spigeline and related chemistry genuinely expels worms, and it was an official anthelmintic of the old United States Pharmacopeia, used for generations. The proving gave the remedy its famous left-sided neuralgic portrait, read in every old headache chapter.

Where the classical picture comes from

The official worm-flower's proving gave the library's most precisely-located head-pain: left eye, stitching, pulse-synchronous. Spigelia became the classical remedy of the violent left-sided neuralgia, read beside its worm-expelling chemistry — a flower with two careers, both real.

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.

Pinkroot's anthelmintic chemistry was genuinely effective — an official worm remedy of the USP for decades, retired when safer vermifuges (santonin's successors, then the modern benzimidazoles) arrived. Its overdose toxicology is also documented. The neuralgias it portrayed are today neurology's — trigeminal neuralgia managed with modern anticonvulsants and microsurgery.

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

RemedyLooks similar because…Tells it apart because…
Sanguinaria canadensisRight-sided sick-headacheSanguinaria owns the right side and the sleep-relief; Spigelia the left with the pulse's beat.
BelladonnaThrobbing headBelladonna throbs hot and red; Spigelia stitches left with the heartbeat.
GlonoinumVascular throbbingGlonoinum surges in waves after heat; Spigelia stitches to the pulse.
Cimicifuga racemosaNeck and head painsCimicifuga's pains run down the neck with gloom; Spigelia's bore the left orbit.
Safety. Severe one-sided head pain with eye symptoms, or a first 'worst-ever' headache, needs urgent assessment; eye pain with vision change is urgent.
