What is Sisaliyus?
Sisaliyus is a single drug of Persian/Unani medicine. Its Latin name is Seseli tortuosum, and in English it is called hartwort or moon carrot. The seeds and, less often, the root of this carrot-family plant are used.
In traditional practice it was given as a warming, drying remedy for trapped wind, cramping stomach pain, slow or painful periods, and coughs with thick phlegm. Some texts also describe it as a diuretic (something that makes you pass more urine).
Here is the honest verdict on the evidence: we could find no published human trials of Sisaliyus for any condition. Everything known about it comes from old texts and from laboratory work on its oil. A long record of traditional use tells you people valued a plant; it does not prove the plant works, and that distinction applies to everything below.
How does Sisaliyus work?
No one has shown how Sisaliyus works in people, so what follows is informed guesswork rather than fact.
The seeds hold an aromatic oil. Oils of this type can relax the muscle wall of the gut in laboratory dishes, which is the usual explanation offered for the traditional use in wind and cramp.
The plant also contains coumarins, a family of plant chemicals found across the carrot family. Some of these are furanocoumarins, which are known to make skin burn more easily in sunlight and to slow down liver enzymes that break down medicines. That chemistry is the main reason for the cautions on this page.
Unani theory explains the plant in its own language, describing it as hot and dry and used to disperse cold, windy states. That is a traditional framework for choosing remedies, not a description of biology as a laboratory would measure it.
What forms does Sisaliyus come in?
Sisaliyus is not a mainstream supplement, and prepared products are hard to find and rarely tested for identity or purity. It usually appears in these forms:
Whole or crushed seed, simmered into a decoction (a drink made by boiling the plant in water).
Powdered seed, taken by the spoonful or worked into a traditional compound with honey or other herbs.
As one named ingredient inside a multi-herb Unani formula, where you may never see it on its own.
Distilled essential oil is sometimes sold. Do not swallow it.
Where it comes from:
Sisaliyus reaches Persian and Unani medicine from Greek roots. The Greek physician Dioscorides described a plant called seseli in the first century, and later Arabic and Persian writers carried the name and the uses forward into Unani materia medica.
In that literature it sits as a modest, well-recognised single drug for wind, cramp and sluggish periods, not as a famous headline remedy. It has stayed a minor entry ever since, which is part of why modern research has passed it by.
Who should avoid Sisaliyus?
- Never use if you are pregnant or think you might be: it is traditionally used to bring on a late period, and that same action can threaten a pregnancy.
- Do not use if you are breastfeeding.
- Do not give it to children.
- Do not use if you take warfarin or any other blood thinner.
- Do not use if you take ciclosporin or tacrolimus (transplant medicines).
- Do not use if you take a statin (cholesterol medicine) or any drug your pharmacist says is affected by grapefruit.
- Do not use if you are having PUVA or other light therapy for a skin condition.
- Do not use if you take a medicine that already makes your skin burn easily, such as doxycycline.
- Do not use if you are allergic to celery, carrot, parsley, fennel or other carrot-family plants.
- Do not use if you have liver disease or kidney disease.
- Do not use if you take lithium.
- Do not use in the two weeks before planned surgery.
- Never swallow the essential oil, and do not put it on your skin before going outdoors.
When should you see a doctor?
Stop taking it and see a doctor the same day if your skin blisters, burns or turns brown after being in the sun, if you bruise or bleed more easily than usual, or if your skin or the whites of your eyes turn yellow.
See a doctor before you start if you take any regular prescription medicine, so a pharmacist can check it against your list.
Do not use Sisaliyus to treat stomach pain that is severe, getting worse, or lasting more than a few days, and do not use it for swelling in your legs or breathlessness. Those need a proper diagnosis, because they can come from the heart, liver or kidneys.
