Spikenard has an adaptogenic effect like ginseng, toning the entire system against stress and particularly strengthening for the respiratory, digestive and reproductive systems. Spikenard is particularly indicated for chronic weakness in the pulmonary region and makes a good soothing expectorant syrup or tincture for coughs and bronchitis. The Native people used Spikenard for pregnancy as a blood builder and digestive tonic. Native to California, it tends to grow on the banks of rushing creeks in fairly deep shade. Needs a moist location with ample shade and well drained soil. Becomes a large shrub to 10 feet. Hardy to zone 4.
