Spikenard (Nardostachys jatamansi) has a long history of use in traditional medicine systems, particularly in Ayurveda and traditional Chinese medicine, where it has been employed for its purported calming and sedative effects. Historically, it has been used to promote relaxation, ease stress, and support sleep, which are related to anxiety symptoms. These traditional uses are largely based on empirical observation and cultural wisdom rather than rigorous scientific study.

Modern scientific research on Spikenard's effects on anxiety is limited and mostly preclinical. A few animal studies suggest that extracts of Nardostachys jatamansi may have anxiolytic (anxiety-reducing) and sedative properties, potentially due to its influence on neurotransmitter systems such as GABA. However, these studies are preliminary, and there is a lack of high-quality human clinical trials confirming efficacy or safety for anxiety disorders.

Therefore, while the use of Spikenard for anxiety is justified by traditional use, scientific validation is minimal. The evidence supporting its use is weak by modern standards, and it should not be considered a primary or proven treatment for anxiety disorders.
