What is Squilla maritima?

Squilla maritima is a homeopathic single drug. It is made from the sea onion, a large bulb that grows on dry ground near the sea. Its Latin name is Drimia maritima, and it is also called squill.

Homeopaths reach for it most often for a wet, rattling cough. It is also used for a streaming nose with hard sneezing. Some use it when a cough brings a sharp stitch in the side.

The remedy is made by diluting the plant over and over, with shaking at each step. At 30C, no plant matter is left in the pill at all. Trials do not show that it works better than a dummy pill.

So this page reports two separate things. One is long use inside a tradition. The other is proof from trials, and long use is not proof that something works.

One warning matters more than the rest. The raw bulb is a poison, strong enough that farmers once used it to kill rats. Very low dilutions, such as the mother tincture, can still hold that poison.

How does Squilla maritima work?

There is no known body process that explains how this remedy could work.

Homeopathy rests on an idea called 'like cures like'. A big dose of raw squill makes people cough, vomit and pass more urine. So a tiny dose is given for coughs and wet chests.

Each round of mixing and shaking is said to leave a trace or 'imprint' of the plant in the water. No test has ever found such an imprint. Chemistry says the plant is simply gone.

At 30C the pills are milk sugar and water, and nothing else. Any relief you feel is most likely a placebo effect. That means a real, felt improvement that comes from the act of taking something you trust, not from the pill itself.

The raw plant is a different story. Its heart chemicals do act on the body, and they can act hard. That is a poison effect, not a healing one.

What forms does Squilla maritima come in?

You will see it sold as small sugar pills, as liquid drops, and as a mother tincture. The mother tincture is the raw plant soaked in alcohol.

Common strengths are 6C, 12C, 30C and 200C. You may also see 3X or 6X, which are much weaker dilutions. Only the mother tincture and the lowest X strengths can hold plant chemicals.

Shop labels do not always make this clear. Check that the strength is printed on the box. If it is not, do not buy it.

Sugar pills are usually made from lactose, a milk sugar. Liquid drops usually hold alcohol.

Where it comes from:

Squill is one of the oldest plant drugs on record. Egyptian and Greek writers named it for chest trouble and for swelling of the legs. The same bulb was long used as rat poison.

Samuel Hahnemann tested it as a homeopathic remedy in the early 1800s. It has stayed in homeopathic books since then, mostly for coughs and colds.

It is a smaller remedy, not one of the famous ones. Its standing rests on one tradition and on a long record of plant use before that.

What does Squilla maritima help with?

• Wet cough with a lot of mucus: This is the main use in homeopathic books. The picture given is a loose, rattling cough where mucus is hard to bring up. No trial has tested this remedy on its own for cough. A few trials have looked at mixed homeopathic cough syrups that list squill as one of several parts. Those cannot show what squill alone did.
• Chest colds and bronchitis (swelling of the airways): Homeopaths use it for a loose chest that feels full and noisy. There is no trial support for this use. A chest cold that lasts more than three weeks, or comes with fever and breathlessness, needs a doctor rather than a remedy.
• Head cold with sneezing and a streaming nose: The classic picture is bouts of violent sneezing with watery discharge and sore, running eyes. This comes from old provings, not from trials. Colds clear on their own in about a week, which makes any remedy look helpful.
• Sharp stitch pain in the side when coughing: Old texts link squill to a stabbing pain in the side of the chest on coughing. No human trial has tested this. Sharp chest pain with breathlessness can be serious and should be checked by a doctor, not self-treated.
• Hay fever sneezing: Some homeopaths use it for hay fever when sneezing and watery eyes lead the picture. Evidence here is very thin. Trials of homeopathy for hay fever have given mixed results and do not single out this remedy.

What are the side effects of Squilla maritima?

• A 30C pill has no drug effect at all; it is milk sugar and water
• Upset stomach in people who cannot handle lactose (milk sugar) in the pills
• Nausea and vomiting from the raw bulb or the mother tincture
• Stomach pain and loose stools
• A slow or uneven heartbeat from low dilutions or the raw plant
• Blurred sight, or seeing yellow or green halos around lights, a warning sign of heart-chemical poisoning
• Headache and muddled thinking
• Itchy rash from handling the cut bulb
• Homeopaths describe a brief flare of symptoms after a dose; this has not been shown in trials

Good to know:

The risk splits sharply by strength.

At 30C and above there is nothing in the pill, so side effects are not expected beyond the sugar or alcohol base. That is the honest reading of the chemistry.

At mother tincture and the lowest X strengths, real harm is possible. Squill poisoning can cause vomiting and dangerous heart rhythms, and deaths have been recorded from the raw plant. This is why the remedy is rated above routine here.

How much Squilla maritima should you take?

• Recommended daily: No dose of this remedy has been shown to work, so no amount can be called effective. Typical labels for a 30C suggest 3 to 5 pills, 2 or 3 times a day, for a few days only. Let the pills melt under your tongue. Never dose yourself with the mother tincture or with 1X and 2X strengths. These can hold real amounts of heart poison. Treat them as a drug, not a home remedy.
• Best time of day: There is no best time. Homeopathic labels usually suggest spreading doses through the day, and taking one at bedtime if the cough is worse at night.
• With or without food: Labels usually say to take it away from food and drink, about 15 minutes before or after. This is a custom of the tradition, not a rule proven by testing.
• Time to effect: Homeopaths expect a change within a day or two for a sudden cough. No trial backs that timing. If nothing has changed in 3 days, stop.
• How long to take it: Use it for a short spell only, such as 3 to 5 days. Stop and rethink if your cough or cold is no better after 3 days. Any cough that drags past three weeks needs a doctor. Do not use it in place of a treatment your doctor has prescribed.
