Zufa (Hyssop): The Herb Behind Sharbat Zufa, and Why the Oil Is Different
Zufa (hyssop) is a small, bitter, camphor-scented mint-family herb, Hyssopus officinalis, that gives its name to the Unani cough syrup Sharbat Zufa. The dried herb in a tea is a mild, old-fashioned chest remedy. The essential oil sold under the same name is a different matter entirely. It contains pinocamphone, a ketone that can trigger seizures, and it has no place in a home.
Before you buy
- English: hyssop
- Urdu, Hindi, Persian, Arabic: zufa, zoofa, zufa khushk (the dried herb), gul-e-zufa (the flowering tops)
- Scientific name: Hyssopus officinalis L., Lamiaceae; a catmint, Nepeta bracteata, is widely sold as zufa in Iranian trade
- Part used: dried leaves and flowering tops; the essential oil is a separate product with separate risks
- Found in: Sharbat Zufa Murakkab and other cough sharbats, joshanda blends
- Safety flag: MEDIUM. Herb tea low risk for adults; oil convulsant; avoid in pregnancy; sharbat is sugar.

What is zufa, and where does it grow?
Hyssop is a woody little perennial, knee-high at most, with stiff square stems, narrow leaves and summer spikes of violet-blue flowers, native to southern Europe, the Middle East and the lands around the Caspian Sea. The Flora of Pakistan describes the leaves as linear, about 20 mm long and 1 to 3 mm wide, smooth, and dotted with oil glands on both faces. Those glands are where the smell lives. Rub a leaf and you get mint crossed with camphor and a bitter edge. Zufa khushk is the dried herb; gul-e-zufa is the same plant cut at flowering, when the oil peaks. Both reach Pakistani and Indian shops dried and imported, and that supply chain is where the identity problem begins.
The herb that is often not hyssop
A 2016 paper in the Iranian journal Traditional and Integrative Medicine compared the old Persian descriptions of zufa with the plants on sale and concluded that the zufa of the classical texts is a close match for Hyssopus officinalis, while most of what Iranian herbal shops sell as zufa is Nepeta bracteata, a catmint. Later quality-control chemistry on hyssop names Nepeta bracteata as the standard adulterant. Since the regional herb trade overlaps heavily with Iran’s, a Pakistani buyer has no reason to assume the bag holds hyssop.
That matters less than it might. Nepeta bracteata is a small mountain annual from Iran to Pakistan with its own tradition as a chest and fever herb, and a 2017 randomised trial in Isfahan tested it against allergic rhinitis. It is not dangerous. It is simply not the plant the Unani books describe.
The check at the pansari: stem and leaf first, then smell
- Pick out a stem piece. Hyssop is a woody perennial: the stems are stiff, square and hard to snap. A soft, thin, much-branched stem belongs to a small annual, not to hyssop.
- Look at the leaves against your palm. Hyssop leaves are needle-narrow, about 2 cm long and only 1 to 3 mm wide, smooth, with tiny gland dots. Leaves much wider than that are not hyssop.
- Rub a pinch for 3 to 5 seconds and smell. Hyssop is sharp, camphor-minty and bitter.
- No smell at all means an old lot. Either plant loses its oil with age, and neither is worth buying scentless.
This tells you which plant you bought. It does not tell you the oil content, and it does not make a sharbat any less sugary.
What tradition says, and what it is in
Unani and Persian medicine class zufa as hot and dry, a munaffis-e-balgham (expectorant) and muhallil (resolver of swellings), prescribed for wet cough with thick phlegm, chronic bronchitis, asthma (zeeq-un-nafas) and colic. The classical way to take it was a decoction with figs, raisins and liquorice, and that recipe grew into the compound syrups sold today.
Sharbat Zufa Murakkab is the product most people meet; murakkab means compound. Formulas vary, but a typical label lists hyssop with figs (injeer), liquorice (mulethi), raisins (munaqqa), fennel or celery seed, marshmallow seed (khatmi), maidenhair fern (parsiaoshan), gulqand and a sugar base, and one major maker’s version is listed with liquorice, figs, gulkand and sugar as its key ingredients. Zufa is a small share of the bottle. Most of it is syrup.
How it compares with the other Unani cough sharbats is on our cough sharbats page; for a child’s cough, read our child cough guide by age first.
What research says
Reasonably supported: that herb tea is low risk for healthy adults at household strength, and that the oil is a convulsant.
Preliminary (lab and animal): antimicrobial, antioxidant and anti-inflammatory activity, summarised in a 2022 review in Oxidative Medicine and Cellular Longevity, which also states that no clinical trials have examined hyssop oil’s adverse effects in humans.
Tradition only: the expectorant and cough use. There is no good human trial of hyssop herb or Sharbat Zufa for cough. A warm sweet syrup soothes a tickly throat for a few minutes, as any warm sweet liquid does. That is the honest size of the effect.
Unsafe: the essential oil by mouth, in steam, or heavily on skin.
Why the oil is a different thing from the herb
Hyssop oil is roughly a tenth to two thirds pinocamphone, depending on where it grew. Pinocamphone is a monoterpene ketone, a chemical cousin of camphor and of thujone, the wormwood ketone, and ketones of this family excite the brain. A 1999 report in the Journal of Neurology described three otherwise healthy people, two adults and a child, who had generalised seizures after taking essential oils for health reasons, and listed hyssop among eleven plant oils known for over a century to provoke convulsions; in rats, hyssop oil causes abnormal brain activity at lower amounts and fatal convulsions at higher ones.
A cup of herb tea carries a tiny fraction of that oil, diluted in water. A bottle of “zufa oil” does not. There is no tested safe amount to swallow, children reach the threshold sooner, and a seller who promises that a few drops in honey will clear a cough is giving advice that can end in an emergency department. Never swallow it. Never put it in a child’s steam bowl, chest rub or ear.
Anyone with epilepsy or a history of fits, including febrile fits in a child: no hyssop oil in any form, and skip strong herb preparations too. Pregnancy: avoid herb and oil; the plant is traditionally an emmenagogue and the 2022 review notes it may provoke uterine contraction. Breastfeeding: no safety data; avoid. Children: never the oil; a sharbat only if the pack states the age is suitable and sets the amount; no honey-based syrup under 1 year. Diabetes: Sharbat Zufa is sugar syrup, count it as sugar. Blood pressure: many compound sharbats contain liquorice, which can raise blood pressure and lower potassium with regular use; check the label and ask your doctor if you take BP tablets or diuretics.
Cough red flags that need a doctor, not a sharbat: a cough lasting more than 3 weeks, blood in the sputum, breathlessness or chest pain, fever over 3 days, night sweats or weight loss, a whooping or barking cough in a child, or any baby under 3 months with a cough. After oil: vomiting, confusion, twitching or a fit means hospital, now, with the bottle.
How it is used sensibly
The old way is still the sane way: a plain infusion. One level teaspoon of dried zufa in a cup of just-boiled water, covered for 10 minutes, strained, with a spoon of honey for anyone over a year old; two cups a day during a chesty cold is the usual household pattern, and the honey does half the soothing because the herb is bitter. In a joshanda it joins banafsha, gaozaban, unnab and the rest; our banafsha and gaozaban page covers those two. For the sharbat, the pack sets the amount and the age. No better after a week? See a doctor. Zufa shares a shop problem with badranjboya, a classical herb replaced by a local catmint, told on our badranjboya page; more ingredient explainers sit in Unani & Herbal, Decoded.
Bottom line
Known: zufa is hyssop, much of what is sold as zufa is a catmint, and hyssop oil contains pinocamphone and causes seizures. Claimed by tradition: an expectorant for wet cough and asthma, usually as a compound sharbat. Uncertain: whether the herb does anything beyond a warm sweet drink. Woody stems, needle leaves and a camphor bite mean real hyssop. The oil is never for home use.
Zufa: common questions
Zufa kya hoti hai?
Zufa is hyssop, Hyssopus officinalis, a small bitter mint-family herb from southern Europe and West Asia. Unani medicine uses the dried leaves and flowering tops as an expectorant for coughs, mostly inside compound syrups such as Sharbat Zufa Murakkab.
Zufa in English?
Hyssop. Gul-e-zufa is hyssop flowering tops; zufa khushk is the dried herb. If the bag turns out to be a soft-stemmed catmint, its English name is simply catmint (Nepeta bracteata).
Sharbat zufa kis kaam aata hai?
Tradition gives it for wet, phlegmy cough, chest congestion and asthma. In practice it is a sweet herbal syrup that soothes the throat briefly. There is no good trial showing it shortens a cough, and it is mostly sugar.
Zufa murakkab mein kya hota hai?
Hyssop plus a mix that varies by maker: figs, liquorice, raisins, fennel or celery seed, marshmallow seed, maidenhair fern, gulqand, and a sugar syrup base. One major maker lists liquorice, figs, gulkand and sugar as the key ingredients. Read your own bottle’s label.
Zufa ke nuksan kya hain?
The herb tea is low risk for adults, though it should be avoided in pregnancy and by anyone with epilepsy. The sharbat adds sugar and often liquorice, which can push up blood pressure. The essential oil is the real danger: it can cause seizures.
Zufa ka tel kyun khatarnak hai?
Hyssop oil contains pinocamphone, a brain-stimulating ketone related to camphor and thujone. It has caused generalised seizures in healthy adults and a child who took essential oils by mouth, and it produces fatal convulsions in animals. There is no safe swallowing amount. Never use it internally or on children.
Kya zufa bachon ko de sakte hain?
Never the oil, in any form, including steam or chest rubs. A compound sharbat only if the pack states it is suitable for the child’s age and sets the amount. For a cough in a baby under 3 months, or any child who is breathless, feverish beyond 3 days or coughing for weeks, see a doctor.
Zufa pregnancy mein?
Avoid it. The herb is traditionally used to bring on periods and the safety literature notes it may stimulate the uterus; the oil adds a seizure risk. For a cough in pregnancy, ask your doctor or midwife what is safe.
Asli zufa ki pehchan kaise karein?
Look at the stem and leaves: real hyssop has stiff woody stems and needle-narrow, smooth leaves about 2 cm long with tiny gland dots, and smells camphor-minty when rubbed. Soft thin stems and broader leaves mean a catmint sold as zufa.
