This is True Spikenard, the Biblical Spikenard, a strong sedative related to Valerian. Traditionally used in India for relaxing mental stimulation, promoting sleep and calming the mind. Used as an infusion, a tea, or as a thick boiled decoction. In India the roots are a well know tranquilizer and may be used alone or along with Valeriana jatamansi (V. wallichi). An infusion of the root is given in hysteria, palpitation of heart, menopause, and various nervous diseases - ammonia, camphor, or cinammon (Cinnamomum verum) may be added to the infusion (tea). A thick boiled decoction of the root is just that much more powerful. For the treatment of indigestion, a compound preparation consisting of cinnamon, fennel (Foeniculun vulgare), ginger (Zingiber officinalie) and sugar in addition to jatamansi is used. The essential oil from the rhizome is used in perfumery and has a tranquilizing effect when massaged on head or burned as incense.
