**OBJECTIVE**
To determine the effect of Ashwagandha extract on sleep.

**METHODS**
A comprehensive search was conducted in CENTRAL, MEDLINE, SCOPUS, Google Scholars, World Health Organization Trials Portal, ClinicalTrials.gov, Clinical Trial Registry of India, and AYUSH Research Portal for all appropriate trials. Randomized controlled trials that examined the effect of Ashwagandha extract versus placebo on sleep in human participants 18 years old and above were considered. Two authors independently read all trials and independently extracted all relevant data. The primary outcomes were sleep quantity and sleep quality. The secondary outcomes were mental alertness on rising, anxiety level, and quality of life.

**RESULTS**
A total of five randomized controlled trials containing 400 participants were analyzed. Ashwagandha extract exhibited a small but significant effect on overall sleep (Standardized Mean Difference -0.59; 95% Confidence Interval -0.75 to -0.42; I2 =  62%). The effects on sleep were more prominent in the subgroup of adults diagnosed with insomnia, treatment dosage ≥600 mg/day, and treatment duration ≥8 weeks. Ashwagandha extract was also found to improve mental alertness on rising and anxiety level, but no significant effect on quality of life. No serious side effects were reported.

**CONCLUSION**
Ashwagandha extract appears to has a beneficial effect in improving sleep in adults. However, data on the serious adverse effects of Ashwagandha extract are limited, and more safety data would be needed to assess whether it would be safe for long-term use.

**ETHNOPHARMACOLOGICAL RELEVANCE**
Ashwagandha (Withania somnifera (L.) Dunal.) is long known for its sleep-inducing effects. Ashwagandha can be proposed as an alternative to the recommended present treatments for insomnia. This study aimed to evaluate the pharmacological effect of Ashwagandha root extract on sleep in healthy subjects and also in the subjects having insomnia.

**MATERIAL AND METHODS**
We performed a randomized, parallel-group, stratified design, placebo-controlled study. A total of 80 eligible participants, 40 in Arm-A (healthy) and 40 in Arm-B (insomnia) were assigned to two groups, either Ashwagandha or placebo and studied for 8-weeks. The assessment was done based on the sleep parameters (Sleep Onset Latency, Total Sleep Time, Wake After Sleep Onset, Total time in bed, and Sleep Efficiency), Pittsburgh Sleep Quality Index and Hamilton Anxiety scale-A questionnaire, mental alertness on rising assessment, and sleep quality questionnaire. Safety and adverse events along with the concomitant medication were also assessed.

**RESULTS**
In both healthy and insomnia subjects, there was a significant improvement in the sleep parameters in the Ashwagandha root extract supplemented group. The improvement was found more significant in insomnia subjects than healthy subjects. Repeat measure Analysis of variance (ANOVA) confirmed the significant improvement in SOL (p 0.013), HAM-A outcomes (p < 0.05), mental alertness (p 0.01), and sleep quality (p < 0.05) of the insomnia patients. A two-way ANOVA was used to confirm the outcomes that denoted sleep onset latency (p < 0.0001) and sleep efficiency (p < 0.0001) as the most improved parameters, followed by TST (p < 0.002) and WASO(p < 0.040). All these parameters (SOL, TST, WASO, TIB, SE, PSQI, HAM-A, Mental Alertness, and Sleep quality) were also statistically assessed for the significant improvement within the group both for the treatment, and the placebo groups in the healthy and the insomnia datasets. Obtained results suggest statistically significant (p < 0.0001) changes between the baseline values and the end of the study results except for the HAM-A and the mental alertness scoresn the healthy subject group.

**CONCLUSION**
The present study confirms that Ashwagandha root extract can improve sleep quality and can help in managing insomnia. Ashwagandha root extract was well tolerated by all the participants irrespective of their health condition and age. Additional clinical trials are required to generalize the outcome.

Introduction Insomnia is a prevalent sleep disorder that can profoundly impact a person's physical health and mental wellbeing. Most of the currently available drugs for insomnia exert adverse effects. Hence, alternative herbal therapies could be effective in treating insomnia. Ashwagandha, a proven "Rasayana" from ancient Ayurveda is having the required potential to treat insomnia. Objective To determine the efficacy and safety of Ashwagandha root extract in patients with insomnia and anxiety. Methods This was a randomized, double-blind, placebo-controlled study conducted at Prakruti Hospital, Kalwa, Maharashtra, India. A total of 60 patients were randomly divided into two groups: test (n = 40) and placebo (n = 20) in a randomization ratio of 2:1. Test product was a capsule containing highest concentration full-spectrum Ashwagandha root extract 300 mg, and the placebo was an identical capsule containing starch. Both treatments were given twice daily with milk or water for 10 weeks. Sleep actigraphy (Respironics Philips) was used for assessment of sleep onset latency (SOL), total sleep time (TST), sleep efficiency (SE) and wake after sleep onset (WASO). Other assessments were total time in bed (sleep log), mental alertness on rising, sleep quality, Pittsburgh Sleep Quality Index (PSQI), and Hamilton Anxiety Rating Scale (HAM-A) scales. Results Two patients, one from each group, did not complete study and the per-protocol dataset (n = 58) included 29 and 19 patients from test and placebo, respectively. The baseline parameters were similar in the two groups at baseline. The sleep onset latency was improved in both test and placebo at five and 10 weeks. However, the SOL was significantly shorter (p, 0.019) after 10 weeks with test [29.00 (7.14)] compared to placebo [33.94 (7.65)]. Also, significant improvement in SE scores was observed with Ashwagandha which was 75.63 (2.70) for test at the baseline and increased to 83.48 (2.83) after 10 weeks, whereas for placebo the SE scores changed from 75.14 (3.73) at baseline to 79.68 (3.59) after 10 weeks. Similarly, significant improvement in sleep quality was observed with test compared to placebo (p, 0.002). Significant improvement was observed in all other sleep parameters, i.e., SOL, SE, PSQI and anxiety (HAM-A scores) with Ashwagandha root extract treatment for 10 weeks. Conclusion Ashwagandha root extract is a natural compound with sleep-inducing potential, well tolerated and improves sleep quality and sleep onset latency in patients with insomnia at a dose of 300 mg extract twice daily. It could be of potential use to improve sleep parameters in patients with insomnia and anxiety, but need further large-scale studies.

**OBJECTIVE**
Despite the historical neurological use of Withania somnifera, limited evidence supports its efficacy for conditions like anxiety and insomnia. Given its known anti-stress properties, this review evaluated its safety and efficacy for anxiety and insomnia.

**METHODS**
We searched Medline, Cochrane Library, and Google Scholar until August 2023 for randomized controlled trials (RCTs) comparing W. somnifera to placebo in patients with anxiety and/or insomnia. Outcome measures included changes in anxiety levels via the Hamilton Anxiety Scale (HAM-A), Sleep Onset Latency (SOL), Total Sleep Time (TST), Wake After Sleep Onset (WASO), Total Time in Bed (TIB), Sleep Efficiency (SE), and Pittsburgh Sleep Quality Index (PSQI) score. We utilized a random-effect model for pooling Mean Differences (MD) with a 95% Confidence Interval (CI). Heterogeneity was assessed through sensitivity and subgroup analysis, and the quality of RCTs was evaluated using the Cochrane revised risk of bias tool.

**RESULTS**
Pooled results from five RCTs (n = 254) demonstrated that W. somnifera significantly reduced HAM-A scores (MD = -5.96; [95% CI -10.34, -1.59]; P = 0.008; I<sup>2</sup> = 98%), as well as sleep parameters such as SOL, TST, PSQI, and SE, but not WASO and TIB.

**CONCLUSION**
While W. somnifera extracts yielded promising results, further research with larger sample sizes is needed to confirm its effects on anxiety and insomnia.

초록:

Ashwagandha (Withania somnifera L. Dunal), an Indian medicinal plant that has been used for centuries to treat insomnia, exhibits a variety of biological activities, such as improving cognitive function, immunity and anxiety. In this study, the effect of enzyme-treated Ashwagandha root extract (EA) and on sleep was evaluated using rodent models. Starch contained in the Ashwagandha root extract was removed by amylase treatment to prepare EA. To evaluate the sleep-promoting activity of EA, a pentobarbital-induced sleep test and electroencephalogram analysis were performed. In addition, the sleep-promoting mechanism of EA was elucidated by analyzing the expression of sleep-related receptors. In the pentobarbital-induced sleep test, EA dose-dependently increased sleep duration. Additionally, electroencephalogram analysis revealed that EA significantly increased δ-wave and non-rapid eye movement sleep times, which are involved in deep sleep, thereby improving sleep quality and quantity. EA also effectively relieved caffeine-induced insomnia symptoms. Furthermore, the γ-aminobutyric acid (GABA) content in the brain and mRNA and protein expression of GABA<sub>A</sub>, GABA<sub>B1</sub>, and serotonin receptors were significantly increased by EA compared to the normal group. In particular, EA showed sleep-promoting activity by binding to various GABAA receptor sites. Collectively, EA exhibited sleep-promoting activity through the GABAergic system and may be used as a functional material to improve sleep deprivation.

Ashwagandha(위타니아 솜니페라) 수면 개선 메커니즘
================================================================================

【1. 코르티솔 감소 (스트레스 호르몬)】

Ashwagandha는 HPA axis(시상하부-뇌하수체-부신 축)를 조절하여
코르티솔 분비를 감소시킵니다.

코르티솔 ↓ → 스트레스 감소 → 수면 품질 향상

【작용 성분】
- Withanolides (위타놀라이드)
- Withaferin A
            
--------------------------------------------------------------------------------

【2. GABA 수용체 활성화】

GABA = 뇌의 억제성 신경전달물질
       (진정, 이완 효과)

Ashwagandha → GABA-A 수용체 활성화
            → 뇌 활동 억제
            → 수면 유도

벤조디아제핀과 유사한 메커니즘이지만
의존성이 훨씬 낮음
            
--------------------------------------------------------------------------------

【3. 신경보호 효과】

산화 스트레스 감소:
- 항산화 효소 활성화
- 미토콘드리아 보호
- 신경세포 손상 방지

→ 뇌 기능 정상화 → 수면-각성 주기 개선
            
--------------------------------------------------------------------------------

【4. 불안 감소 (Anxiolytic effect)】

불안 → 불면증의 주요 원인

Ashwagandha는:
- 세로토닌 수치 조절
- 도파민 대사 개선
- 편도체 활성 억제

→ 불안 감소 → 수면 개선
