Asparagus racemosus, known as Shatavari in Ayurvedic medicine, has a long history of traditional use for supporting the nervous system and alleviating symptoms such as nervousness, anxiety, and stress. Within Ayurvedic practice, Shatavari is classified as a "rasayana" herb, believed to promote vitality, calm the mind, and support mental balance. Classical Ayurvedic texts mention its use for balancing "vata dosha," which is associated with nervous energy, restlessness, and anxiety-like symptoms.

Scientific research on Shatavari's effects specifically for nervousness or anxiety in humans is limited. Some preliminary animal studies have suggested that extracts of Asparagus racemosus may have adaptogenic or anxiolytic properties, potentially due to its saponin and alkaloid content, which might influence neurotransmitter pathways. For example, some studies in rodents indicate mild anti-stress or calming effects, though these findings are not robust or widely replicated.

Overall, the primary basis for using Asparagus racemosus to support or treat nervousness stems from traditional Ayurvedic practices rather than strong scientific evidence. While the herb is commonly used in traditional medicine for this purpose, more rigorous clinical research is needed to validate its efficacy and safety for nervous system-related conditions in humans.
