Spigelia anthelmia in Homeopathy: Uses, Picture and Limits

Key takeaways

• Spigelia is the picture of stitching, left-sided pain. Classic texts describe sharp, radiating neuralgia above and behind the left eye, spreading over the left side of the head and face.
• Touch and motion are unbearable. The person keeps very still, because moving the eyes, the head or the body sharpens the pain.
• The pain follows the sun. The older literature describes a headache that starts in the morning, peaks around midday and fades towards evening.
• It comes from a poisonous tropical herb. Pinkroot is a relative of the strychnine tree; potentised preparations are diluted far past the point where the plant remains.
• Its territory is a red-flag territory. A sudden or "worst ever" headache, a painful red eye with blurred vision or haloes, and any chest pain or palpitations with faintness or breathlessness are emergencies first.

What is Spigelia made from?

Homeopathic Spigelia is prepared from the dried whole plant of Spigelia anthelmia, an annual herb of the West Indies, Central America and tropical South America, often found as a weed of fields and roadsides. It grows to knee height with whorls of pointed leaves at the top of the stem and slender spikes of small pinkish-white flowers. Its species name, anthelmia, means "against worms", and for centuries the plant was used in the Caribbean and South America to expel intestinal worms; Demerara pinkroot was traded under that name. Our guide to reading Latin remedy names explains why old names like this stay on labels.

The source deserves an honest note. Spigelia belongs to the Loganiaceae, the same family as the strychnine tree that gives Nux vomica, and the raw plant is poisonous; even as a worm medicine it was regarded as a risky herb that affected the nervous system and the heart. It is never something to prepare or use at home. The homeopathic preparation makes a tincture of the dried plant and carries it through repeated dilution and succussion to the labelled potency. At the common potencies the arithmetic says no molecule of the plant remains. Our potencies guide explains what that means, and why it is also the reason science is sceptical.

What is the Spigelia picture?

The Spigelia picture is pain like a hot needle. Imagine someone who woke feeling ordinary, and by mid-morning has a stitching, burning pain fixed above and behind the left eye. It shoots into the eyeball, the temple and the cheek, and seems to pulse outward from one point. By noon it is at its worst. They sit bolt upright and perfectly still, because turning the eyes, moving the head, a footstep on the floor or the touch of a hand sharpens it. As the afternoon wears on, it fades, and by evening it has largely gone.

Boericke (1927) describes Spigelia as a remedy of neuralgia, especially of the left side, with pain that rises and declines with the sun and is worse from touch, motion, noise and jarring. He describes the eyeballs as feeling too large and painful on turning them, and pain deep in the orbit. The face is part of the same picture, with tearing, stitching pain along the left cheekbone and jaw.

The chest is the other half of the classic material. Hahnemann's provers recorded violent palpitations, visible or audible, and stitching pains around the heart, worse from movement and from bending forward. The older texts discuss this cardiac picture at length, but in modern terms these are emergency symptoms rather than remedy material, and this page handles them that way.

There is a small, odd mental keynote the literature repeats: a dread of sharp, pointed things such as pins and needles. Homeopaths value it because it fits the character of the pain itself.

What makes it better or worse?

The traditional modalities centre on touch and movement. Spigelia is worse from the slightest touch, from jarring and motion, and from the rising sun, and better lying still with the head raised.

The side and the sun pattern are the modalities homeopaths weigh most; our guide to modalities, better and worse explains how they are read.

What is Spigelia traditionally discussed for?

In homeopathic literature, Spigelia is traditionally discussed for stitching, radiating, left-sided neuralgia. One of our acute pages carries the Spigelia-like pattern beside its neighbours, with the red flags first.

Head and eye

• Stitching, radiating pain above and behind the left eye, exquisitely sensitive to touch and motion: sudden one-sided head pain around the eye. A new, severe or "worst ever" headache is a medical emergency, and that page sets out the red flags before anything else.

Nearby pages that discuss other pictures

• An eye-strain headache and sinus headache with pressure describe head pain around the eyes where homeopaths compare other pictures; the classic texts reserve Spigelia for pain that is sharp, stitching and one-sided rather than dull and pressing.

What is Spigelia not?

Spigelia is not "the migraine remedy" or "the cluster headache remedy", and the head and eye are a place where a remedy picture must never come before a diagnosis. A sudden, severe headache that peaks within a minute or so, a "worst ever" headache, headache with fever and a stiff neck, confusion, weakness, slurred speech or changed vision, or a headache after a head injury needs emergency care. A painful red eye with blurred vision, haloes around lights, nausea or a fixed pupil may be acute glaucoma and needs same-day emergency eye care. Pain in the chest, palpitations with faintness or breathlessness, or chest pain spreading to the arm or jaw is an emergency, whatever the old cardiac material says. Our guide to red flags first sets these out.

Homeopaths separate it from its neighbours like this:

The traditional distinction with Sanguinaria is the side: both are described as sun headaches, but Spigelia settles over the left eye and Sanguinaria over the right.

What potencies is Spigelia sold in?

Spigelia is sold most often as 30C pellets, with 6C and 200C available from homeopathic pharmacies. It is a less common shelf remedy than the polychrests and is more often ordered than picked up in a shop. Potency describes the preparation process, not an amount of plant: 30C means thirty successive 1:100 dilutions with succussion between them. Our potencies guide explains the scale and what remains in the vial, and why low-potency products of toxic sources carry their own labelling.

This page deliberately gives no frequency or instructions for taking Spigelia. That depends on a whole case, not a remedy name. Read the product label, and talk to a qualified practitioner about an individual situation.

What remedy lists don't tell you

Two things the "remedies for headaches" lists leave out:

• Side and timing carry the picture. A list gives Spigelia for headache, which is almost every headache. The classic authors described something narrow: left-sided, stitching, needle-like, building with the morning sun and fading by evening, and unbearable to touch or movement. The companion details, such as the eyeballs feeling too big or a dread of pins, are what the tradition used to confirm it; our guide to the symptoms alongside the symptom explains why companions matter.
• The old cardiac pages belong to history. Nineteenth-century texts discuss Spigelia's heart symptoms at length, from a time before ECGs and emergency cardiology. Chest pain and palpitations are now questions for a clinic, and a modern reading of Spigelia keeps them there.
