Theridion curassavicum

Made from the orange spider of the Antilles — the tropic tree-spider whose venom is a genuine ion-channel research subject, and the classical remedy of the noise-and-motion vertigo.

The whole picture, in one breath

Think of vertigo with every sense a trigger: dizziness and nausea at the least motion of the head, at the least noise, worse closing the eyes (the world spins when the lids shut), the noise of a conversation setting off the swaying — and the books' great vertigo remedy of the sensitive constitution. The vertigo-of-every-trigger: that is Theridion.

The substance, in plain words

The orange tree-spider of the Antilles is a genuine venom-bearer — its peptides, like all spider venoms, act on the nervous system's ion channels and are studied in modern pharmacology. The proving gave the remedy its celebrated vertigo portrait: motion, noise and closed eyes each a trigger.

Where the classical picture comes from

The Antilles tree-spider's proving gave the library its most specific vertigo portrait — the closed-eye, noise-triggered spinning; Theridion became the remedy of the sensitive, swaying constitution, standing in the spider chapter beside Tarentula's rhythm.

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.

Spider venoms are a genuine frontier of pharmacology — ion-channel-modulating peptides studied for pain, rhythm and neuromuscular disease — and the orange spider's kin share that real research life. Motion-triggered vertigo is now vestibular medicine's: the Epley manoeuvre, vestibular rehabilitation and diagnosis by examination. The venom is researched; the vertigo is treatable.

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

RemedyLooks similar because…Tells it apart because…
Cocculus indicusMotion sickness, vertigoCocculus is the emptied carer with the motion-sickness; Theridion the closed-eye, noise-triggered vertigo.
Conium maculatumVertigo lying and turningConium's vertigo comes with lying down and hard glands; Theridion's with the closed eyes and the noise.
Gelsemium sempervirensDizziness, weaknessGelsemium is heavy, drooping and trembling; Theridion is the trigger-sensitive spinning.
PetroleumVertigo, chronic motionPetroleum serves the chronic seasick disposition; Theridion the land-vertigo of the senses.
Safety. Recurrent vertigo, or vertigo with hearing loss or neurological signs, needs ENT and neurological assessment.
