What is cicely?
Cicely is a soft, ferny garden herb with a sweet aniseed taste. Its full name is sweet cicely (Myrrhis odorata). It belongs to the carrot family, like parsley, fennel and dill.
Cooks use the leaves with sour fruit, above all rhubarb and gooseberries. The herb tastes sweet, so less sugar is needed in the pan. The green seeds and the root are eaten too.
It grows across much of Europe, in hedges, damp meadows and old gardens. In Britain it was once planted near houses as a kitchen and bee plant. Today most people meet it as a flavouring, not as a medicine.
Here is the honest verdict. Cicely has a long record as food and as a folk remedy. There are almost no human studies of it as a medicine.
Traditional use is not proof that a plant works. It is also not proof that a plant is safe. Both points apply to cicely, and they apply to everything below.
One real hazard is worth knowing before anything else. Several deadly plants in the same family look like cicely, including hemlock. Picking the wrong one has killed people.
How is cicely thought to work?
The short answer is that nobody has shown how it works in people. No trial has tested a cicely preparation against a dummy treatment.
Most of what is said about it comes from its smell and taste. The plant is rich in a scent compound called anethole, which also gives anise and fennel their flavour. In lab and animal work, anethole appears to relax gut muscle and ease wind.
Whether that happens after a cup of cicely tea is not established.
Cicely leaves also hold flavonoids, a family of plant pigments. In test-tube studies these mop up reactive molecules. That is a chemistry result, not a health result in a person.
The sweet taste is the one effect you can see for yourself. Adding cicely to stewed rhubarb lets you use less sugar. That is a cooking trick, not a medical action.
Some older writers said the root was a tonic for weak or elderly people. There is no modern work to support that idea. Treat it as folklore.
In short, the plausible parts of cicely are its flavour and its sugar-sparing use in the kitchen. The medical parts rest on tradition and lab hints. Those hints have not been followed up in humans.
What forms does cicely come in?
Cicely is mostly a kitchen herb, not a supplement. You are most likely to meet it as:
- Fresh leaves, chopped into stewed fruit, salads, cream or omelettes. - Green unripe seeds, eaten raw or used as a flavouring. - Ripe dried seeds, used as a spice.
- Root, boiled as a vegetable or candied, mainly in older recipes. - Dried leaf, sold loose or in herbal tea blends. - A flavouring in some European liqueurs and aperitifs.
Tinctures and capsules exist but are uncommon. They are not standardised, so strength varies between makers.
Essential oil of cicely is rare. Swallowing any concentrated plant oil is a different matter from eating the herb, and it is not something to try at home.
Garden centres sell the live plant. If you grow it, you know what you have, which removes the biggest risk attached to this herb.
Where does cicely come from?
Cicely was a staple of European kitchen gardens for centuries. Writers from the 16th and 17th century listed it among sweet pot-herbs. Gerard and Culpeper both described it.
Old uses recorded in those books included:
- A tonic for older or run-down people. - A remedy for wind, upset stomach and poor appetite. - A gentle cough herb.
- A poultice for bruises and sore joints. - A rub for beehives and wooden floors, for the scent.
In northern Britain and Scandinavia it was planted near doors and in churchyards. Cooks valued it most as a sugar saver with rhubarb, long before sugar was cheap.
None of these records were tests. They tell you what people believed and what they did. They do not tell you whether the herb helped.
The culinary use has held up and is still alive today. The medicinal use has largely faded, and modern science never picked it up.
When to see a doctor
Get emergency help at once if you or anyone else has eaten a wild plant thought to be cicely and then develops:
- Burning or numbness in the mouth, drooling or trouble swallowing - Muscle twitching, shaking or a fit - Vomiting, confusion or severe stomach pain - A slow heartbeat (bradycardia), trouble breathing or collapse
Take a piece of the plant with you if you safely can.
See a doctor the same day for swelling of the lips, tongue or throat, a spreading rash, or wheeze after eating the herb.
Make a routine appointment if indigestion, cough, appetite loss or tiredness lasts more than one to two weeks.
In the UK, EU and US, cicely is an ordinary food herb and may be sold freely. It is not approved as a medicine for any condition anywhere, and no health claim is authorised for it.
