What is Shaghayegh?
Shaghayegh is the bright red corn poppy, Papaver rhoeas. It is a single herb used in Persian and Unani medicine, mostly as a syrup or tea made from the dried petals. Traditional healers give it to calm restlessness, help sleep and soothe a dry, tickly cough.
This is not the opium poppy. Papaver rhoeas contains different, much weaker alkaloids (plant compounds) and no morphine. Even so, it is mildly sedating (sleep-inducing), so it is not a harmless flower tea.
The evidence verdict: the traditional record is long and consistent, but human trial evidence is essentially absent. A long history of use is not proof that something works, and that point applies to everything below.
How does Shaghayegh work?
Nobody has shown clearly how Shaghayegh works in people. The best-supported idea is simple: the petals contain alkaloids that appear to damp down nerve activity, which would explain the mild drowsiness reported for centuries.
Laboratory and animal studies suggest a calming effect on the central nervous system (the brain and spinal cord). Those results do not automatically carry over to a cup of petal tea.
The soothing effect on a sore throat may be simpler still. The petals are rich in mucilage, a slippery gel that coats irritated tissue.
What forms does Shaghayegh come in?
Dried red petals are the usual form. They are steeped as a tea or simmered into a sweet syrup, the classic Persian and European preparation for coughs.
You may also find tinctures (alcohol extracts) and capsules of powdered petal. These are less traditional and rarely standardised, so the alkaloid content is unknown.
Poppy seeds from this plant are a food, not a medicine. The green leaves and unripe seed capsules are not used and have caused poisoning in grazing animals.
Where it comes from:
Shaghayegh appears in Persian and Unani writing as a cooling, moistening herb for heat, wakefulness and dry cough. Greco-Arabic physicians such as Avicenna described the red poppy in this role.
The same use spread across Europe, where sirop de coquelicot (red poppy syrup) was a pharmacy staple for children's coughs into the twentieth century.
Who should avoid Shaghayegh?
- Do not give it to babies or children under 12 in any form, including cough syrup, because they are far more sensitive to its sedative (sleep-inducing) effect.
- Never use it if you are pregnant or trying to become pregnant.
- Never use it if you are breastfeeding.
- Do not use it if you are taking sleeping tablets, benzodiazepines (calming medicines such as diazepam), or opioid painkillers such as codeine or tramadol.
- Do not drink alcohol while using it.
- Do not drive, cycle or operate machinery after taking it.
- Do not use it in the two weeks before any planned operation or procedure involving anaesthesia.
- Do not use it if you have a lung condition that affects your breathing, such as COPD (a long-term lung disease) or sleep apnoea (breathing pauses during sleep).
- Do not use it if you have liver disease or kidney disease, because no safe dose has been worked out for you.
- Do not use it if you have had an allergic reaction to poppies before.
- Never eat the green leaves, stems or unripe seed pods of the plant; only the petals and the ripe seeds are used.
When should you see a doctor?
See a doctor if your cough lasts more than two weeks, brings up blood or coloured phlegm, or comes with fever or breathlessness. Also see a doctor if sleep problems continue after two weeks, or if you feel low, panicky or unable to cope.
Get emergency help straight away if someone becomes very drowsy and hard to wake, breathes slowly or shallowly, or has a swollen face, lips or tongue. If a child has swallowed any poppy preparation, contact a poison centre or emergency service at once.
