Nardostachys jatamansi

Nardostachys jatamansi (D. Don) DC. is most frequently used as a soothing infusion or decoction of its roots and rhizomes in India, Nepal, and Bhutan. In Ayurvedic practice, the powdered rhizome is taken as a tea to calm nerves, reduce anxiety, and settle gastrointestinal “gas”; the Ayurvedic Pharmacopoeia of India recommends an infusion of the dried root/rhizome for these purposes (Ayurvedic Pharmacopoeia of India, 2008). In Nepal, the same dried plant material is made into a mild tea that is widely drunk for nervous tension and headaches (Bennett et al., 2021). Regional pharmacopoeias and ethnomedicine references from the Himalaya also note decoctions used to quiet mental agitation and as a heart tonic (Verschaeve & Van Peteghem, 2004), while herbarium and ethnobotanical surveys from the eastern Himalayas have long recorded the plant as a household remedy for insomnia and nervous complaints when taken as an infusion (Kirtikar & Basu, 1918). Outside of internal use, poultices of the crushed rhizome are applied to the forehead or temples for headaches and anxiety in several Himalayan communities (Bennett et al., 2021; Blatter et al., 1928).

Practical recipe: mild infusion for occasional nervous restlessness. Measure roughly 2–3 g of chopped dried rhizome (about one small thumbful) and add to 250 mL just‑boiled water. Cover and steep 10–12 minutes, then strain and sip. The preparation is mild; if you feel thirsty or woozy, stop. Jatamansi is not recommended in pregnancy or while breastfeeding (NRCCM, 1998; Poletti, 1982), and avoid combining with sedatives or alcohol. The herb is not a substitute for prescription medication for anxiety or insomnia.

Active constituents well documented for this species include the sesquiterpenes valeranone and nardosinone, together with oxo‑manno‑sugars such as nardosinone and jatamansides, which plausibly account for its long‑standing use as a nervine and sedative (Chandrashekar et al., 2012; Bos et al., 1998; Evans, 2009). These constituents are abundant in the roots and rhizomes and have been detected in commercial extracts and hydroalcoholic preparations.

Current relevance: clinical work continues on standardized jatamansi extracts for sleep and anxiety, and the powdered rhizome or standardized extracts are widely available in Ayurvedic shops and herbal outlets today (AHP, 2008; Bos et al., 1998).

Fragrance and cosmetics:
Rhizomes and roots yield an essential oil (sometimes hydrodistilled) and concrete/absolute used in fragrance accords and perfumery bases as a fixative or base-note. Oil yields are typically in the low single-digit mass percentage; properties relevant to use include sesquiterpene dominance, substantial bicyclic ketone content, and a warm, musky, earthy dry-down. Extracts or isolates may be employed in cosmetics as fragrance components; like many essential oils, use levels are constrained by IFRA standards for root-derived valerian-type oils and by general cosmetic safety guidance (e.g., RIFM, INCI-related concentration limits). The high sesquiterpenoid fraction imparts substantive tenacity and a characteristic aromatic profile.

Sustainability and sourcing:
Populations are harvested from wild herbaceous stands in the Himalaya and adjacent ranges; supply is constrained by slow rhizome regrowth and habitat pressures. Initiatives emphasize community-based harvesting, altitude-aware cultivation trials, and restriction of wild root collection to mature plants to support regeneration and limit erosion. Industry traceability and geographic origin documentation are used to mitigate adulteration (often with valerian roots) and to align with conservation priorities for high-altitude alpine/herb communities.
