Celery is about 95% water, so a large plate of it is a small amount of food.
One stalk carries around 25 mg of potassium and a useful share of the day's vitamin K.
Frying the stalks before they meet liquid is what stops khoresh-e karafs turning to mush.
In Iran, karafs is grown for both its stalks and leaves, and Persian cooks make good use of each. They cut the stalks short and fry them so they hold their shape, then add the leaves with mint and parsley. Celery is mostly water, so it gives a stew freshness and body without making it heavy. Even after an hour of simmering, you can still tell exactly what it's.
Known to botanists as Apium graveolens.

Why It Matters
Celery gives a whole family of spring khoresh its character, and it's an inexpensive way to bring freshness and substance to the plate. It won't lower your blood pressure on its own, whatever the juice trade promises. What it can do is put vegetables at the centre of the meal instead of leaving them on the side.
As chewing gets harder and appetite fades, older people often eat less. Celery can't solve that, but a stew built around it's soft, savoury, and easy to finish while still bringing potassium and fibre. Anyone on warfarin (a blood-thinning medicine) should keep their intake steady rather than swinging between none and a lot.
Adds bulk and fibre to a meal for almost no calories.
Supplies potassium and vitamin K in an everyday, cookable form.

What It Contains
Primary compounds
Apigenin is the flavonoid (a family of protective plant compounds) that gives celery its bitterness at the back of the tongue.
Luteolin is a second flavonoid (a family of protective plant compounds), studied mostly in the laboratory rather than in people.
Phthalides are the aroma compounds behind that unmistakable smell.
Potassium and water together are what make celery filling for so few calories.
Vitamins
Vitamin K, Folate, Vitamin C
Other notable constituents
Minerals: Sodium · Fiber: About 1.6 g per cup, chopped

In the Laboratory
From laboratory work, not from people taking it
Apigenin from celery shows anti-inflammatory activity in laboratory models. Rated: early research.
What studies in people show
Celery is a recognised food allergen with documented severe reactions, particularly in Europe. Rated: strong evidence.

Preparation and Kitchen Use
Spring, in the stew. Raw with salt on a hot afternoon.
Cut into two-finger lengths and fry in oil before adding liquid.
Chop the leaves fine and add them in the last ten minutes.
Eat raw on the sabzi khordan plate with feta and bread.
Braise slowly with lamb, mint and dried lime for khoresh-e karafs.
Cut the stalks into short lengths, fry them in oil until the edges colour, then add them to the stew.
Use the leaves as a herb.
Keep the leaves, chop them with mint and parsley, and stir them in near the end.

Medicines and Interactions
Medication interaction:
Warfarin — Celery carries vitamin K. Steady intake matters more than avoidance. (moderate concern)
Medication interaction:
Blood pressure medicines — Concentrated celery seed extract may add a small lowering effect. The vegetable itself is unlikely to. (low concern)
General caution:
Levothyroxine — A very high-fibre meal can slow absorption. Leave a gap between the tablet and the meal. (low concern)

Who Should Be Careful
General caution:
The leaves contain furocoumarins. Handling them in quantity in strong sun can burn the skin of susceptible people.
Allergy:
Celery is one of the recognised food allergens. Reactions can be severe, and they can involve the stalk, the leaf and the seed alike.
Pregnancy and breastfeeding:
Celery seed extract is a different thing from the vegetable. It is concentrated, and pregnancy is a reason to leave it alone.
Allergy:
Diagnosed celery or celeriac allergy.

Pregnancy, Children and Older Adults
Pregnancy and breastfeeding
Pregnancy and breastfeeding:
Celery as a vegetable is fine in pregnancy and is eaten freely across Iran. Concentrated celery seed extracts are a different matter and are traditionally avoided, so leave supplements alone unless a clinician says otherwise.
Children
Children:
Raw stalks are a choking risk for the under-fours because the strings don't break down. Cut them lengthways and short, or serve them cooked in the stew, where children usually eat them without argument.
Older adults
Medication interaction:
Stewed celery is soft, savoury and easy to chew, which matters more than any nutrient here. Keep vitamin K intake steady if warfarin (a blood-thinning medicine) is in the picture.

Traditional Persian Perspective
Persian temperament: Cool & Dry (2nd degree). Cooling and drying. Persian cooks balance it with warm spice and fat, which is exactly what the stew does.
Persian medicine describes karafs as cool and dry and links it with the kidneys and the flow of urine. That's a traditional classification, not a tested effect. The old texts were careful about it too: hakims warned against large amounts in pregnancy long before anyone had a reason why.
In the Household
The seed was ground into digestive powders and taken after heavy meals.
The leaf was simmered into a spring broth for people recovering from winter illness.
The stalk was eaten raw with salt as a thirst-quencher in hot weather.
Khoresh-e karafs belongs to spring in Tehran. The first tender stalks go into the pot with plenty of mint and parsley, then the stew is served over chelow. For many households, that first plate is how you know the season has turned.

Through the Year
Spring:
Spring
The season. Tender stalks, heaps of herbs, and the stew everyone waits for.
Summer:
Summer
Eat it raw with salt when the heat kills your appetite.
Autumn:
Autumn
Thicker, stronger stalks. Better stewed than eaten raw.
Winter:
Winter
Stored celery is tough. Cook it long or use the leaves.

Questions People Ask
Does celery juice do what people claim?
No. The trials don't exist. Celery juice is a pleasant, low-calorie drink with some potassium, and everything beyond that's marketing.
Are the leaves edible?
Yes, and in Persian cooking they're the point. They carry more flavour than the stalk.
Why does my khoresh turn to mush?
The celery went in raw. Fry it first so the outside firms up before it meets liquid.
Is celery really negative-calorie?
No. It's very low in calories, but chewing doesn't burn more than it gives. The idea is a myth that refuses to die.
