Nagarmotha Benefits for Hair, Skin and Digestion, Honestly
If you’ve ever pulled a grassy weed from a flower bed and found little brown nuts on its roots, you’ve met nagarmotha (nut grass, motha). Gardeners hate it. Perfumers, hakeems and grandmothers making ubtan love those fragrant tubers. Here are the real nagarmotha benefits for hair, skin and digestion, with a plain verdict on each.
In brief
- Plant: Cyperus rotundus, called nut grass or purple nutsedge in English
- Part used: the small, hard, dark-brown tubers on the roots
- Smell: warm, woody and earthy, a bit like vetiver
- Fair uses: ubtan, hair packs, a fragrant addition to oil, as cosmetics
- By mouth: a traditional digestive, best kept to a practitioner’s advice
- Always: patch test anything that goes on skin or scalp

What is nagarmotha, and is it the weed in my lawn?
Very likely. Cyperus rotundus grows almost everywhere warm. It has shiny, stiff, grass-like leaves, a stem that is triangular when you roll it between your fingers, and reddish-brown flower spikes. Underground, it builds chains of tubers linked by thin wiry runners.
Snap a dried tuber and it smells pleasant. That scent comes from essential oils in the tuber, mainly sesquiterpenes such as cyperene and rotundone. Rotundone, by the way, is the same aroma molecule behind the peppery note in black pepper and some red wines.
Did you know? Nut grass is often listed as one of the world’s worst weeds, and papyrus, the plant ancient Egyptians made paper from, belongs to the same genus.
Pulling the leaves rarely kills it. The tubers stay behind and sprout again, which is why it’s so hard to clear from a garden. If you want to use your own, dig the tubers rather than pulling the tops, and only from soil that has never been sprayed with weedkiller.
- Nagarmotha vs bhadramusta: some sellers use “nagarmotha” for a larger related species, Cyperus scariosus. Both are sold under the same name; the uses overlap.
- Nagarmotha vs vetiver (khus): different plants with a similar earthy smell. Khus roots are long and stringy; nagarmotha tubers are small and knobbly.
Is nagarmotha good for hair? What three voices say
The popular claim
Hair videos call nagarmotha a secret for thick, long, black hair. It’s said to stop hair fall, kill dandruff, delay greying and make hair grow faster, usually mixed with amla, reetha and shikakai.
The traditional view
Ayurveda uses musta in hair and scalp preparations for its cooling, drying and fragrant qualities, and in Unani perfumery it’s an old base note in attars. Grandmothers added the powder to herbal hair washes and oils mostly so the hair would smell good and feel less greasy.
Our honest take
There’s no human evidence that nagarmotha grows hair, stops genetic thinning or reverses grey. What it does well is scent, a slightly drying feel on an oily scalp, and a pleasant ritual. Lab work shows its oil can slow some fungi and bacteria, which is interesting for dandruff but unproven on a real scalp. Depends If you enjoy a herbal hair pack, it’s a fair fragrant addition. If you’re losing a lot of hair, find the cause first: our hair pack powders comparison grades the popular ones honestly.
How do you use nagarmotha in a hair pack or ubtan?
These are cosmetic amounts. Do a patch test 48 hours before the first full use: a pinch of paste behind the ear or inside the elbow, rinsed after 15 minutes. Redness, itching or bumps means skip it.
- Hair pack (shoulder-length hair): mix 1 tablespoon nagarmotha powder, 2 tablespoons amla powder and 2 tablespoons hibiscus or methi powder with about 120 ml warm water or plain dahi into a thick paste.
- Apply to the scalp and lengths in sections. Leave 20 to 30 minutes. Rinse well with lukewarm water; powders can leave grit, so a mild shampoo helps.
- Ubtan for the body: 1 teaspoon nagarmotha powder, 2 tablespoons besan, a pinch of haldi and enough rose water or milk to make a soft paste.
- Use it on damp skin, rub gently in circles for 1 to 2 minutes, leave 10 minutes, and rinse. Keep it off the face if your skin is sensitive, and never on broken skin.
- Fragrant oil: drop 1 tablespoon of crushed dry tubers into 100 ml coconut or sesame oil, warm gently on the lowest heat for 10 minutes (do not let it smoke), cool, strain and use within 3 months.
- How often: once a week for packs and ubtan. More is not better, especially for dry hair.
For the full traditional ubtan, see our guide to besan and turmeric ubtan. Ubtan powders sold online with “whitening” claims deserve a hard look first: read our ubtan powder safety guide.
Does nagarmotha help digestion?
This is its oldest medicinal job. Ayurveda gives musta to “kindle digestion”, ease loose motions and settle a heavy, bloated stomach, often with ginger. One classic mix, shadanga paniya, is a fever-time drinking water made with musta and five other herbs.
The honest picture: animal work suggests the tuber can relax gut muscle and calm diarrhoea, which fits the tradition. Good human trials are missing. So it’s plausible but unproven, and the amount by mouth is for the pack or a practitioner to set.
- Loose motions: ORS comes first, always. A herb doesn’t replace fluids.
- See a doctor for blood in stool, diarrhoea over 2 days in adults or 24 hours in a small child, signs of dehydration (very little urine, dizziness, sunken eyes), fever of 39 °C or above, or severe belly pain.
- Bloating that keeps coming back, with weight loss or trouble swallowing, needs a check-up rather than a powder.
Which nagarmotha myths should you drop?
Myth: it turns grey hair black
Nothing in nagarmotha dyes hair or restarts pigment. Henna and indigo colour hair; the tuber just adds scent.
Myth: nagarmotha removes facial hair for good
This is the biggest nagarmotha search of all, and there’s nothing behind it. No paste or oil made from the tuber stops hair follicles, and rubbing powders hard on the face just irritates it. Our guide to ghair zaroori baal explains what does work, and why new facial hair in women can be a sign worth checking with a doctor.
Myth: it’s a weight loss herb
Some sellers market it this way. There’s no reliable evidence, and any “herbal slimming” product deserves suspicion for hidden medicines.
Who should be careful with nagarmotha?
Skin and scalp: fragrant plants can cause allergic rashes. Patch test, and stop if you get itching, redness or small blisters. People with eczema or a broken, sore scalp should skip it.
By mouth: avoid it as medicine in pregnancy and breastfeeding, and don’t give it to children. If you take diabetes or blood pressure medicine, ask your doctor before adding any herb. The pack or a practitioner sets any amount.
Stop and seek help for swelling of the lips or face, wheezing, or a widespread rash. That’s an allergy emergency.

How do you buy and store nagarmotha?
Whole tubers are best. They should be hard, dark brown, about the size of a fingertip, with fine hairs or scales, and smell clearly woody when broken. Powder that smells of nothing is old.
Store in a glass jar away from damp and sunlight. Whole tubers keep a year or more; powder loses its scent in about six months. Grind small batches in a dry spice grinder, then wipe it out well.
Nagarmotha questions people ask
What is nagarmotha used for?
Nagarmotha is used in hair packs, ubtan, perfumes and attars for its woody fragrance, and in Ayurveda as a digestive herb. The cosmetic uses are fair and pleasant. The medicinal ones are traditional and not well tested in people.
What is nagarmotha called in English?
Nagarmotha is called nut grass or purple nutsedge in English, botanically Cyperus rotundus. Some sellers also sell a related species, Cyperus scariosus, under the same name.
Is nagarmotha good for hair growth?
There’s no evidence that nagarmotha makes hair grow faster or stops hair fall. It adds fragrance and a clean, slightly drying feel to a pack. If you’re shedding a lot, check iron, thyroid and recent illness first.
Can I apply nagarmotha on face?
Yes, a small amount in a besan or clay ubtan is a traditional face use. Patch test first, keep it away from eyes and broken skin, and rinse off after about 10 minutes. Stop if your skin stings or turns red.
Nagarmotha aur khus mein kya farq hai?
Nagarmotha ki choti, sakht gaanthen hoti hain, jab ke khus (vetiver) ki lambi, patli jaden hoti hain. Dono ki khushboo mitti jaisi hoti hai, is liye log inhe mila dete hain. Istemal mein dono khushboo ke liye zyada kaam aate hain.
Does nagarmotha remove unwanted facial hair?
No. There’s no evidence that nagarmotha powder or oil removes facial hair or slows its growth. Threading, waxing, creams made for the face or laser are the real options, and sudden new facial hair in women deserves a hormone check.
Can nagarmotha turn grey hair black?
No. Nagarmotha has no dye and doesn’t restart pigment. For colour, pure henna and indigo work; for early greying, a doctor can check B12, thyroid and other causes.
Is nagarmotha safe in pregnancy?
Don’t take nagarmotha by mouth during pregnancy or breastfeeding, because its safety hasn’t been established. A patch-tested cosmetic pack is less of a concern, but check with your doctor if you’re unsure.
Can I use nagarmotha from my garden?
You can dig the tubers if you’re sure of the plant and the soil has never been sprayed with weedkiller or pesticide. Wash, dry in the shade until hard, then store. If in doubt, buy a labelled pack.
Does nagarmotha help with loose motions?
Tradition uses it for loose motions, and animal work fits that, but it isn’t proven in people. ORS and fluids come first. See a doctor for blood in stool, dehydration, high fever or diarrhoea lasting more than 2 days.
