What is Shirkhesht?

Shirkhesht is a sweet, crumbly manna — a dried sugary sap that collects on the twigs of Cotoneaster shrubs (Cotoneaster manna) in Iran and Afghanistan. In Persian and Unani practice it is used mainly as a very gentle laxative for children and for easing dry cough and fever.

It is a single-herb product, not a blend. The dried flakes are usually soaked in warm water and the sweet liquid is given by spoon.

What the evidence shows: tradition here is strong and old, but modern human trial evidence is thin and mostly small and Iranian, so shirkhesht is best treated as a traditional remedy rather than a proven treatment. Long use in a tradition is not proof that something works, and that gap applies to everything below.

How does Shirkhesht work?

Shirkhesht is mostly sugars, including mannitol, a sugar alcohol that the gut absorbs poorly.

Sugars of this kind pull water into the bowel, which softens stool and makes it easier to pass. This is the same basic idea behind other osmotic (water-drawing) laxatives.

Traditional writers also describe it as cooling and soothing for a dry throat. That part has not been tested in people, so treat it as tradition, not proven action.

What forms does Shirkhesht come in?

The usual form is loose dried flakes or small pale lumps. These are soaked in warm water, strained, and the sweet liquid is given by spoon.

You may also find it as a ready-made syrup or as a sweetened drink sold for children. Powdered and capsule forms exist but are much less common in traditional use.

Where it comes from:

Shirkhesht appears in classical Persian and Unani medical writing as a mild, safe purgative fit for children and frail people. Iranian and Afghan families have used it for generations for constipation and for newborn yellowing of the skin. It is still sold openly in bazaars and herb shops across the region.

What does Shirkhesht help with?

• Constipation, especially in children: This is the best-supported use and the reason most people buy it. The sugar alcohols in shirkhesht draw water into the bowel, which is a well-understood way to soften stool. Human trial evidence specific to shirkhesht is limited, so the confidence comes mostly from long use and from how similar sugars behave.
• Newborn jaundice (yellow skin and eyes): Traditional Iranian practice gives shirkhesht water to jaundiced newborns, and a few small hospital studies there have looked at it alongside phototherapy (light treatment). This is important: newborn jaundice can become dangerous and needs a doctor to check bilirubin (a yellow pigment in the blood). Never use shirkhesht in place of medical care for a yellow baby.
• Dry cough and sore throat: Tradition treats it as a soothing, moistening remedy for a dry throat. Any benefit is likely the same mild coating effect you get from honey or any thick sweet liquid. We found no human trials testing shirkhesht for cough.
• Fever, as a cooling drink: Persian and Unani texts class it as cooling and give it as a sweet drink during fever. This is a comfort measure only. There is no trial evidence that it lowers body temperature.

Which foods are rich in Shirkhesht?

1. Cotoneaster manna flakes: the raw material itself, sold as a food-like sweet
2. Traditional Iranian shirkhesht drink: flakes soaked in water and strained
3. Mannitol-containing foods such as mushrooms and celery: a different source of the same sugar alcohol

Practical Tips:

Shirkhesht is not part of a normal diet anywhere; it is used as a remedy or a sweet drink.

What are the side effects of Shirkhesht?

• Loose stools or diarrhoea
• Bloating and wind
• Stomach cramps
• Nausea if a large dose is taken at once
• Dehydration and thirst if diarrhoea continues, especially in babies and older people

Good to know:

Most side effects are mild and come from taking too much. They usually settle within a day of stopping or cutting the dose.

The one to watch is fluid loss. A baby or frail adult with ongoing loose stools can get dry quickly, and that needs a doctor.

How much Shirkhesht should you take?

• Recommended daily: No official dose has been established by modern research. Traditional practice uses roughly 5-15 g of the dried manna for an adult, soaked in warm water and strained, once a day. Child doses are much smaller and are normally set by a practitioner. For infants, do not guess a dose — ask a doctor or pharmacist first.
• Best time of day: Usually taken in the evening or at bedtime, so the effect arrives the next morning. Some people prefer it in the morning on a free day.
• With or without food: Either works. Taking it with a full glass of water matters more than food, because osmotic (water-drawing) laxatives need fluid to work properly.
• Time to effect: Usually 6 to 12 hours for a bowel movement. Some people need a second dose the following day.
• How long to take it: Short-term use only. Traditional use for constipation runs a few days at a time. If constipation has not improved after about a week, stop and see a doctor. Do not use any laxative daily for weeks on end without medical advice.
