Introduction
Sleep disorders, particularly insomnia, are increasingly recognized as major public health concerns affecting physical health, mental well-being, and quality of life. In Ayurveda, sleep (Nidra) is considered one of the three Trayopasthambhas (sub-pillars of life), alongside Ahara (diet) and Brahmacharya (regulated conduct). Disturbance of sleep, termed Anidra or Nidranasha, is primarily associated with aggravation of Vata Dosha, imbalance of Pitta Dosha, psychological stress, anxiety, and improper lifestyle practices. Ayurvedic management of sleep disorders focuses on restoring physiological and psychological balance through herbal medicines, dietary regulation, behavioral modifications, and rejuvenative therapies. Among these, herbal interventions play a significant role in promoting natural and restorative sleep.1
Ayurvedic perspective on sleep disorders
According to classical Ayurvedic texts, adequate sleep is essential for maintaining strength (Bala), complexion (Varna), nourishment (Pushti), immunity (Ojas), and longevity. Sleep deprivation may result in fatigue, irritability, cognitive impairment, emotional instability, and increased susceptibility to disease. Therefore, Ayurvedic treatment aims not only to induce sleep but also to address the underlying causes of sleep disturbances.
Important ayurvedic herbs for sleep disorders
Ashwagandha (Withania somnifera):
Ashwagandha is a renowned Rasayana herb known for its adaptogenic, anxiolytic, and rejuvenating properties. It reduces stress and cortisol levels, improves sleep quality, and enhances overall resilience. Clinical studies have demonstrated its effectiveness in improving sleep onset, sleep efficiency, and total sleep duration in individuals with insomnia.2
Jatamansi (Nardostachys jatamansi):
Jatamansi is traditionally regarded as a Nidrajanana Dravya (sleep-promoting herb). It possesses sedative, anxiolytic, and neuroprotective properties that help calm the mind and reduce stress-related sleep disturbances. It is commonly used in insomnia associated with anxiety and mental exhaustion.3
Tagara (Valeriana wallichii):
Tagara is widely used in Ayurveda for managing insomnia, nervousness, and anxiety. Its sedative effects are attributed to modulation of neurotransmitter pathways, particularly gamma-aminobutyric acid (GABA), which plays a crucial role in sleep regulation.
Brahmi (Bacopa monnieri):
Brahmi is classified as a Medhya Rasayana and is known for enhancing cognitive function, reducing anxiety, and promoting mental calmness. Its neuroprotective and adaptogenic properties contribute to improved sleep quality and emotional stability.
Shankhapushpi (Convolvulus pluricaulis):
Shankhapushpi is another important Medhya Rasayana that supports mental relaxation and stress reduction. It is frequently prescribed in sleep disorders associated with anxiety, nervous tension, and psychological stress.4
Contemporary scientific evidence
Modern research increasingly supports the traditional use of Ayurvedic herbs for sleep disorders. Clinical trials have demonstrated significant improvements in sleep quality, sleep duration, anxiety levels, and overall well-being following supplementation with Ashwagandha and other herbal preparations. Experimental studies on Jatamansi, Tagara, and Brahmi have shown sedative, anxiolytic, antioxidant, and neuroprotective effects that may contribute to their sleep-promoting actions.
These herbs appear to act through multiple mechanisms, including regulation of stress hormones, enhancement of GABAergic neurotransmission, reduction of oxidative stress, and modulation of neurotransmitters involved in sleep and mood regulation.

Conclusion
Ayurvedic herbal interventions offer a holistic and evidence-supported approach to the management of sleep disorders. Herbs such as Ashwagandha, Jatamansi, Tagara, Brahmi, and Shankhapushpi not only improve sleep quality but also enhance mental well-being and stress resilience. By addressing the root causes of sleep disturbances, these traditional remedies provide a comprehensive strategy for promoting healthy sleep and overall wellness. Further clinical research is needed to strengthen the evidence base and facilitate their integration into modern sleep medicine.
