Jatamansi, also known as Himalayan spikenard, Indian nard, or simply spikenard, is Nardostachys jatamansi, an aromatic high-altitude Himalayan perennial whose rhizomes and roots have been valued in Ayurveda, Unani medicine, traditional Chinese medicine, perfumery, and ritual traditions. It is also a conservation-sensitive medicinal plant. Kew reports the species as Critically Endangered under the IUCN category it cites, and international trade in the taxon has long been regulated under CITES through the older listed name Nardostachys grandiflora, now treated by modern botanical authorities as a synonym of Nardostachys jatamansi.
Botanical Identity
Common names: jatamansi, Himalayan spikenard, Indian spikenard, Indian nard, nard, muskroot
Botanical name: Nardostachys jatamansi (D.Don) DC.
Important synonym: Nardostachys grandiflora DC.
Family: Caprifoliaceae
Kew recognizes Nardostachys jatamansi as the accepted species and treats Nardostachys grandiflora as a synonym. The plant is native across parts of the Himalaya into western and central China and northern Myanmar and grows in high-elevation subalpine to subarctic habitats.
What Part Is Used?
The principal traditional materials are the aromatic rhizome and root. These underground parts contain volatile oils rich in sesquiterpenes and other aromatic compounds. Because harvesting the rhizome usually destroys or severely damages the plant, medicinal demand has direct conservation consequences that leaf-harvested herbs may not face.
Ayurvedic and Traditional Use
Jatamansi has a long place in South Asian medical traditions, especially Ayurveda, where it has been associated with the mind, sleep, emotional balance, and nervous-system complaints. Traditional sources also describe uses connected with epilepsy-like disorders, agitation, memory, cardiovascular complaints, digestive concerns, and hair and skin care. In Unani traditions it is also known as a valued aromatic medicinal.
In Chinese medicine, related material has traditionally been used in patterns involving qi movement, pain, and digestion. These traditional uses deserve accurate historical description, but they are broader than the conditions that have actually been studied in modern human trials.
Key Constituents
Research has identified numerous terpenoids and other aromatic compounds, with sesquiterpenes forming an important part of the chemistry. Modern analytical work continues to characterize the essential oil and its major sesquiterpenoid constituents. The plant's chemistry can vary with origin, processing, plant material, and extract type.
What Human Research Shows
Human evidence exists, but it is still limited. A small randomized placebo-controlled trial in 40 people with stage-1 essential hypertension reported reductions in systolic and diastolic blood pressure over four weeks in the jatamansi group. The study was small and short, so it should be viewed as preliminary rather than proof that jatamansi can replace established blood-pressure treatment.
A small comparative clinical study also evaluated jatamansi powder in people with primary insomnia and reported improvement in several sleep measures. That study included only a small number of participants and lacked the kind of large, blinded, placebo-controlled design needed for firm conclusions.
A 2025 randomized double-blind placebo-controlled study also investigated Nardostachys jatamansi as an adjunct to escitalopram in major depressive disorder. The existence of newer clinical research is encouraging, but the overall evidence base is still far smaller than the herb's broad traditional reputation.
Preclinical Research
Laboratory and animal studies have investigated antioxidant, neuroprotective, anti-inflammatory, antimicrobial, cardiovascular, and nervous-system effects. A 2026 study of jatamansi essential oil documented complex terpene chemistry and in-vitro antioxidant and antibacterial activity. These findings help explain scientific interest but should not be converted directly into claims that the herb treats infections, neurologic disease, or other serious conditions in people.
Conservation Status
Conservation is not a side note with jatamansi—it is central to responsible use. Kew currently reports an IUCN category of Critically Endangered for Nardostachys jatamansi. Scientific reviews have repeatedly identified wild collection, destructive rhizome harvesting, habitat pressure, and difficulties with botanical authentication as major concerns.
Substitution and confusion with other aromatic Himalayan roots have also been documented. Buying by common name alone is therefore a poor practice both medicinally and environmentally.
CITES and International Trade
The taxon has been regulated in CITES Appendix II under the name Nardostachys grandiflora. Modern taxonomic sources now treat that name as a synonym of Nardostachys jatamansi, and CITES committees have worked to align trade databases and nomenclature with the accepted name.
CITES Appendix-II controls do not necessarily mean all commerce is banned; they regulate international trade so that it can be documented and managed. Plant annotations can exempt specific types of material or finished products. Anyone importing, exporting, wholesaling, or commercially sourcing jatamansi should check the current CITES listing, annotation, source documentation, and applicable national rules rather than relying on an old herb-supplier description.
Safety
Modern reviews describe many experimental studies as showing relatively low toxicity at ordinary research exposures, but comprehensive human safety data are still limited. Because jatamansi may affect the nervous and cardiovascular systems, concentrated products deserve caution alongside sedatives, blood-pressure medicines, psychiatric medicines, or other drugs acting on the central nervous system.
Safety during pregnancy and breastfeeding has not been adequately established. Concentrated medicinal use should be avoided unless appropriately supervised.
Ethical Sourcing
For jatamansi, “sustainable” should mean more than a marketing word. Prefer material with a clearly stated botanical name, country of origin, cultivated or legally harvested source, and appropriate CITES documentation when relevant. Root and rhizome botanicals place particular pressure on wild populations because harvest can kill the plant.
The Bottom Line
Jatamansi is an important Himalayan medicinal and aromatic plant with centuries of use in Ayurveda and other traditional systems and a growing but still limited body of human research. Small trials suggest possible effects on sleep, blood pressure, and other areas, but the evidence is not yet strong enough for broad therapeutic claims. Its conservation story is just as important as its pharmacology: Nardostachys jatamansi is a high-value, threatened root herb whose international trade is regulated through CITES. Responsible sourcing, correct botanical identity, and restraint in health claims are essential.
