Khaksi (Khubkalan): The Seed in Sharbat Khaksi, and What It Isn’t
Khaksi (khubkalan, London rocket seed, Sisymbrium irio) is a tiny reddish mustard-family seed that swells into jelly in water, and it is the seed behind Sharbat Khaksi, the Unani fever syrup that generations of mothers have poured during measles and chickenpox. Three names, one seed, plus a complete false friend: the “khaksi” or “kheksi” vegetable is a spiny gourd with no connection at all. Here is what the seed is, what the tradition expects of it, what a mucilage seed can and cannot do in a viral fever, and where a doctor takes over.
The short version
- English: London rocket seed; also sold as hedge mustard seed
- Urdu/Hindi: khaksi, khubkalan, khubkala, khoobkala, khakshi
- Persian/Iranian: khakshir, khak shir (often a different plant, flixweed, see below)
- Scientific name: Sisymbrium irio, family Brassicaceae (the mustard family)
- Part used: the seed, whole, soaked, or as a sharbat
- Traditional role: fever and rash illnesses, cough and hoarseness, a gentle bowel softener
- Safety flag: measles and chickenpox are doctor matters; the sharbat is sugar syrup; drink water with the seed
- Not this: khaksi or kheksi sabzi, the spiny gourd Momordica dioica

What khaksi actually is
London rocket is a weed. It grows along roadsides and field edges across Pakistan, northern India, Iran and the Middle East, a knee-high plant with yellow four-petalled flowers and long thin pods packed with seed. The seed is what the pansari sells: tiny, orange-brown to rusty red, with a pitted surface, so small that a teaspoon holds hundreds. Drop a pinch in water and within minutes each grain wears a clear coat of jelly. That coat is mucilage, a plant gum that soaks up water, and it is the whole character of the seed.
The English name recalls the plant’s spread over the ruins of London after the Great Fire of 1666, which explains the odd label on export packs.
Khaksi, khubkalan, khakshir: one seed or three?
In Pakistan and India, khaksi and khubkalan are the same thing, Sisymbrium irio seed; the two names simply come from different regions and different classical books. Khakshir is the Persian word, and here the identity shifts. In Iran the seed sold as khakshir is very often flixweed, Descurainia sophia, a different plant in the same mustard family, with the same look, the same jelly coat and the same traditional uses. A 2016 review of Persian medicine sources describes khakshir soaked in water and served as a sharbat for constipation, palpitation, skin eruptions and more, all on flixweed.
Why the Iranian swap matters, and why it doesn’t
If you buy “khakshir” imported from Iran, you may well be holding Descurainia sophia rather than Sisymbrium irio. For botanical identity that is a real mix-up, and a lab or a botanist is the only way to be sure. For the folk use it changes almost nothing: both are small mucilage seeds used the same way for the same complaints. Know the difference so a label cannot fool you; do not pay extra for either on the strength of a name.
The false friend: khaksi ki sabzi is a gourd
Type “khaksi” into a search box and half the results are about a vegetable. That is kheksa, kheksi, kakrol or kantola, the spiny gourd Momordica dioica, a small green knobbly cousin of karela that is fried with spices across Bengal, Bihar and eastern Uttar Pradesh. It is a vegetable, not a seed, not a Unani fever remedy, and it does not swell in water. “Khaksi ke beej” in a Unani context always means the mustard-family seed on this page.
What Unani tradition uses khaksi for
Classical Unani texts list khaksi as a dafe-e-humma (fever reliever), and it is one of the most famous fever drugs of the system. It is given during khasra (measles), lakra kakra or jadari (chickenpox and, historically, smallpox), and in other eruptive fevers, with the idea that it helps the rash “come out” fully and the fever settle. It is also used for cough, chest congestion, hoarseness and loss of voice, and as a mild laxative. The seed is soaked overnight, or boiled briefly, and taken as a drink, often with munakka (large dried grapes) and unnab (jujube).
Sharbat Khaksi, the shelf product most people know, follows that recipe. The listed ingredients in the Hamdard version are khaksi seed, unnab fruit, badiyan (fennel, not star anise, in Unani usage), gaozaban leaf and sugar; makers describe it as a syrup for low-grade fever, measles, chickenpox and seasonal viral fevers. Unnab’s own “blood purifier” story is examined on the unnab page, and gaozaban, which has its own identity tangle, is covered on the gaozaban page.
Khubkalan munakka: why the pairing?
Munakka are big, seeded, dark raisins. In the fever drink they sweeten and flavour a bland jelly-seed water so a feverish child will drink it, and add a little sugar and potassium when appetite is gone; tradition also credits them with cooling and softening the bowel. There is no trial on the pair. Think of it as a palatable fluid dressed in Unani logic, which is not a bad thing to be.
What a mucilage seed can and cannot do in measles or chickenpox
Measles and chickenpox are viral illnesses. Nothing in khaksi kills a virus, shortens the illness or prevents its complications. Reviews of both Sisymbrium irio and its Iranian stand-in find laboratory and animal work pointing to fever-lowering, anti-inflammatory and pain-easing activity, and almost no human trials. That is the honest state of play.
What the drink can do is modest and real. A sick child who will not eat still needs fluids, and a cool, slightly sweet, slippery drink goes down more easily than plain water, soothes a sore throat, and keeps the bowel soft. The jelly seed is a bulk laxative: it absorbs water, so it needs water taken with it. Comfort and fluids, yes; treatment, no
The rash timelines, the fever rules and the red flags belong to the paediatric pages: measles (khasra) in children, chickenpox (lakra kakra) danger signs and bachon ka bukhar by age. Read those; this page will not repeat them.
How khaksi is traditionally prepared at home
These are household drink amounts, framed as tradition, not a prescription.
- Rinse: swirl 1 to 2 teaspoons of seed in a cup of water and pour the water off; this floats away dust and chaff.
- Soak: cover the seed with 250 ml clean water and leave 30 minutes to overnight. It swells into a loose jelly.
- Flavour: add 4 to 5 washed munakka (soaked alongside), a squeeze of lemon, and sugar or misri only if needed.
- Serve: stir and drink seeds and all, or strain for a small child who dislikes the texture. Follow with a glass of plain water.
- Joshanda style: some families simmer the seed 5 minutes with munakka and unnab instead of soaking; it tastes rounder and is served warm for cough.
For a shelf sharbat, follow the pack or the hakeem who prescribed it. Diluted in water it is a sweet drink, not a substitute for ORS in a child who is vomiting or has loose motions.
Real vs padded: the pansari’s soak test
The check that works, and what it proves
Put a pinch in a glass of water. Real khaksi turns into clear-coated jelly grains within a few minutes, the same way isabgol or tukh malanga does. A sample that sits gritty at the bottom has something else in it: sand, chaff, or a cheaper seed with no mucilage. This test proves the seed is a mucilage seed; it does not prove which mucilage seed, so it will not separate Sisymbrium from Descurainia. Pair it with colour and size. Khaksi is rusty orange-brown and very small; black or large seeds are the wrong thing. Store it dry and airtight: once damp, the mucilage goes sticky and mouldy.
Who should be careful
Fever rules come first. A baby under 3 months with any fever, a child with a temperature of 39 °C or above, any fever lasting more than 3 days, a child who is drowsy, breathing fast, refusing all fluids, passing little urine, or has a rash that does not fade when pressed: these are doctor-now situations, and no sharbat changes that. Measles and chickenpox can bring pneumonia, ear infection, dehydration and, rarely, brain inflammation; the paediatric pages list the signs. Sugar: the commercial sharbat is sugar syrup. People with diabetes should use the soaked seed with little or no added sugar instead. Babies under 1: no honey in the drink, and no herbal sharbats at all without the paediatrician’s say-so. Choking and bowel: the seed is a bulk laxative and must be taken with water; do not give dry seed to young children. Pregnancy: food-level amounts as a drink are traditional, but there is a Persian tradition of using khakshir to bring on labour at the end of pregnancy, so treat regular use before term as an “ask your doctor”. Allergy: rare, but anyone sensitive to mustard-family foods should start with a sip. Loose stools: stop if motions turn watery.
Bottom line
Khaksi, khubkalan and khakshir are one small jelly-coated seed (with an Iranian stand-in from the same family), and khaksi ki sabzi is an unrelated gourd. Unani tradition trusts the seed in fever and rash illnesses; the evidence behind that is laboratory and animal work, not human trials. Used as a cool, slippery, lightly sweet drink with munakka, it is a kind way to keep a sick child drinking, and that is its real value. Measles and chickenpox themselves need a doctor’s eye and the fever rules by age. More ingredient explainers are gathered in Unani & Herbal, Decoded.
Khaksi: the questions people ask
Khaksi in English kya kehte hain?
Khaksi is London rocket seed, from the plant Sisymbrium irio in the mustard family. Export packs sometimes say hedge mustard seed. It is unrelated to the khaksi or kheksi vegetable, which is spiny gourd.
Khaksi aur khubkalan ek hi cheez hai?
Yes. Khaksi and khubkalan (also spelt khubkala or khoobkala) are two regional names for the same Sisymbrium irio seed. Khakshir is the Persian name, and Iranian khakshir is often a related plant, flixweed, used the same way.
Sharbat Khaksi kis kaam aata hai?
It is a Unani syrup traditionally given for low-grade fever, measles, chickenpox and seasonal viral fevers, to keep a patient drinking and comfortable. It does not kill the virus or shorten the illness. It contains sugar, so it is a sweet drink, not a medicine in the modern sense.
Khasra (measles) mein khaksi kyun di jati hai?
Unani tradition holds that khaksi helps the rash come out fully and the fever settle, which is why it is the classic measles drink. Modern medicine finds no effect on the virus; the real benefit is fluids and comfort. A child with measles still needs a doctor and the fever rules by age.
Khubkalan munakka ke fayde kya hain?
Munakka sweeten and flavour the bland seed water, add a little sugar and potassium when appetite is gone, and are traditionally considered cooling and bowel-softening. The pair is a palatable fluid for a feverish person. No trial has tested the combination.
Khaksi ke nuksan kya hain?
Taken without enough water it can cause bloating or hard stools, and in excess it loosens the bowel. The sharbat form is high in sugar. Rare allergy is possible in people sensitive to mustard-family foods. The main harm is indirect: treating a serious fever at home and delaying the doctor.
Khaksi bachon ko de sakte hain?
As a soaked, well-diluted drink, children over 1 can have it if a paediatrician has seen the illness and agrees. Never give dry seed to young children, never add honey under 1, and never use it in place of ORS or a doctor’s visit for a baby under 3 months with fever.
Khakshir seeds kya hain?
Khakshir is the Persian name for the same kind of seed. In Iran it is usually Descurainia sophia (flixweed), soaked in water and served as a sharbat for constipation, heat and skin eruptions. In Pakistan and India the seed sold as khaksi is Sisymbrium irio. Same use, slightly different plant.
Khaksi ki sabzi aur khaksi ke beej mein farq?
Completely different plants. Khaksi or kheksi sabzi is spiny gourd (Momordica dioica), a knobbly green vegetable related to karela. Khaksi ke beej are tiny red-brown mustard-family seeds that turn to jelly in water and go into Unani fever drinks.
Khaksi ka price kya hai?
It is an inexpensive pansari seed sold by the 50 or 100 grams; prices vary by city and season, so no figure is given here. A pack that costs far more than ordinary khaksi is being sold on a name, not on quality.
Can khaksi be taken for constipation?
Yes, that is one of its traditional uses, and it works like isabgol: the jelly coat adds bulk and softness. Take it with a full glass of water. If constipation is new, painful, lasts beyond two weeks or comes with blood or weight loss, see a doctor.
Khaksi real hai ya nahi, kaise pata karein?
Soak a pinch: real seed swells into clear jelly grains within minutes. Gritty residue means sand or a non-mucilage seed. The test cannot tell Sisymbrium from Descurainia; only a botanist or lab can. Check colour too: rusty orange-brown and very small.
