Nagarmotha: Traditional Uses, Evidence & Safety

TL;DR

Nagarmotha is the rhizome of Cyperus scariosus, a sedge distinct from musta (Cyperus rotundus). Ayurvedic and Unani texts use it as a diaphoretic, tonic, and liver remedy. Laboratory and animal studies report anti-inflammatory and liver-protective signals, but no human clinical trials of nagarmotha were identified. Safety data in humans are lacking.

What it is

Nagarmotha is the Ayurvedic name for Cyperus scariosus R.Br., a perennial sedge in the family Cyperaceae (review). It is a different species from musta, the Ayurvedic name for the related Cyperus rotundus, though the two are close botanical relatives. The medicinal part is the rhizome (underground stem), which yields an aromatic essential oil. Phytochemical surveys of the rhizome list essential oils, sesquiterpenes (including cyperene), flavonoids, steroidal saponins, ketones, and polyphenolic compounds (review).

Traditional use

Nagarmotha has an extensive ethnomedicinal record across Ayurveda, Siddha, and Unani practice. Traditional texts describe the rhizome as a diaphoretic (promoting sweating) and a general tonic, with reported use in fever, spasms, and liver-related complaints (book chapter; review). Unani physicians know the same drug as Saad Kufi, recorded by Ibn Sina (Avicenna) in his Kitab al-Adviya al-Qalbia as a cardiac remedy still in Unani use (ex-vivo cardiac study). These are traditional and historical claims, not clinical proof: the research record is examined separately below.

What modern research says

Inflammation (laboratory studies)

In a laboratory study, a methanolic extract of C. scariosus rhizome showed antioxidant activity about half that of ascorbic acid at 50 µg/ml, and in a protein-denaturation assay its anti-inflammatory activity exceeded that of diclofenac sodium at high concentrations. GC-MS analysis followed by molecular-docking simulations identified several compounds predicted to interact with the human COX-2 enzyme (PMC study). These are in-vitro and computational findings: they point to anti-inflammatory chemistry, not a proven effect in people.

Liver protection (animal studies)

An animal study tested an aqueous-methanolic extract of C. scariosus (500 mg/kg) against acetaminophen- and carbon-tetrachloride-induced liver damage in mice and rats. Pretreatment cut mortality from a lethal acetaminophen dose from 100% to 30% and significantly lowered the toxin-elevated liver-enzyme markers (ALP, GOT, GPT) after both chemical insults (study abstract). This is animal evidence only; no human liver studies exist.

Blood pressure and heart function (animal and ex-vivo studies)

A 50% ethanolic extract of the root (Saad Kufi) significantly reduced systolic blood pressure in adrenaline-induced hypertensive rats (Nafees et al., 2020). Separately, the same type of extract increased heart rate, ventricular developed pressure, and cardiac work in isolated rat hearts studied ex vivo on a Langendorff apparatus (DOAJ-indexed study). Both findings are preclinical, with no human translation yet.

What the evidence does not support (yet)

No human clinical trials of nagarmotha, randomized or otherwise, were identified for any indication. The digestive, diaphoretic, and tonic uses remain traditional claims, and the anti-inflammatory, liver-protective, and cardiovascular signals come entirely from laboratory, animal, or ex-vivo work.

Safety & contraindications

Dedicated human safety data for nagarmotha are lacking. In animal toxicity testing, a combination formulation containing C. scariosus showed no acute toxicity in mice at single oral doses up to 2000 mg/kg (PMC study): a limited animal finding, not human safety evidence. There are no data on use in pregnancy or breastfeeding and no systematic study of interactions with medications. Until human data exist, use should involve a qualified practitioner rather than self-direction.

FAQs

What is nagarmotha?

Nagarmotha is the Ayurvedic name for Cyperus scariosus R.Br., a sedge in the family Cyperaceae. The medicinal part is the aromatic rhizome, which is also distilled into cypriol essential oil used in perfumery (review).

Is nagarmotha the same as musta?

No. Nagarmotha (Cyperus scariosus) and musta (Cyperus rotundus) are different species in the same genus. They are close relatives and are sometimes confused, but the Ayurvedic drug names refer to distinct plants.

What is nagarmotha used for in Ayurveda?

Traditional texts record the rhizome as a diaphoretic and general tonic, with use in fever, spasms, and liver-related complaints; Unani medicine (as Saad Kufi) additionally records it as a cardiac remedy (book chapter; review). These are traditional uses, not clinically proven effects.

Does modern research support nagarmotha's uses?

Only at the preclinical level. Laboratory work suggests anti-inflammatory chemistry (COX-2 interaction), and animal studies report liver protection against chemical toxins and blood-pressure lowering (PMC study; study abstract). No human clinical trials were identified.

Is nagarmotha safe?

Human safety data are lacking. Animal testing of a formulation containing it showed no acute toxicity at high single doses, but that does not establish safety in people. There are no data for pregnancy, breastfeeding, or drug interactions: consult a qualified practitioner before use.

No established human dose exists. The animal studies cited above used research doses (e.g., 500 mg/kg of extract in rodents), which do not translate into a human recommendation.
