Objective: The present study was conducted to investigate the effect of Viola odorata extracted syrup on the quality and patterns of sleep in patients with depression or obsessive-compulsive disorder (OCD) as add-on therapy. Design: A pilot double-blind randomized placebo-controlled trial. Settings/Location: Psychiatric Clinic of Imam Hossein Hospital, Tehran, Iran. Subjects: Participants were 16-15 years of age with mild and moderate depression or OCD having insomnia. Interventions: This pilot study was conducted on patients with insomnia divided into two groups with depression (40 patients) or OCD (43 patients). Each group randomly assigned into two arms with the same conditions at baseline. The intervention arm daily received 5 mL V. odorata syrup every 12 h for 4 weeks, and the control arm received 5 mL placebo syrup every 12 h for 4 weeks. None of the participants was deprived of their routine treatment for depression or OCD. Outcome measures: The scores of insomnia symptoms were evaluated using total score of the Pittsburgh Sleep Quality Index (PSQI) and the scores of its components, the depression score using the final Beck depression inventory-II (BDI-II) score, and OCD score using the Yale-Brown Obsessive-Compulsive Scale (YBOCS). Results: The total PSQI score was found to be improved significantly in the intervention arms with depression or OCD ( p p = 0.009) and YBOCS ( p = 0.001) scores in the intervention arms. Conclusions: V. odorata syrup significantly improved insomnia symptoms and the scores of depression and OCD.
Background Insomnia is the most common sleep disorder that reduces quality of life. Objectives Due to side effects of hypnotic drug and the increasing demand for alternative medicine substitutes, violet oil (VO) was used in this study. VO is a known medication in Iranian traditional medicine that induces sleep in insomniac patients. Patients and methods This study was conducted as an experimental pretest-posttest evaluation on VO efficacy in 50 patients with chronic insomnia in Iranian Traditional Medicine Clinic of Mashhad University of Medical Sciences, Mashhad, Iran. Treatment consisted of intranasal drop of VO, two drops containing 66 mg of VO in each nostril nightly before sleeping for one month. All patients were asked to complete an Insomnia Severity Index (ISI) questionnaire before the start of the trial and after one month of treatment. Results Improvements in sleep and ISI scores were significantly greater in patients after a month receiving VO drop in comparison with before starting treatment (P Conclusions VO can be presented as a safe, well-tolerated, and effective herbal preparation in patients with chronic insomnia.

Mechanistic basis
This use is associated with the plant's sedative / sleep support action. Further evidence for that pharmacology:
Common violet (Viola odorata L., Violaceae) has shown various medical applications. Current study aimed to compile a review over chemical composition and medicinal properties of this plant in modern phytotherapy and its related multipotential products from traditional Persian medicine (TPM). Medicinal applications of V. odorata and respective products were derived from credible pharmaceutical textbooks of TPM (10th-18th century AD). In parallel, electronic databases including PubMed, Scopus, and ScienceDirect were explored for targeted purposes. Management of cough, fever, common cold, headache, insomnia, epilepsy, constipation, palpitation, dyspnea, dysuria, and skin diseases is of most applications of V. odorata, reported in TPM. On the other side, this herb plant has exerted antiinflammatory, analgesic, antioxidant, diuretic, antihypertensive, and antibacterial activities in modern phytotherapy. Violet TPM therapeutic preparations are including violet oil in the form of nasal or topical application for neurologic and skin disorders as well as pill, decoction, sweet syrup, and confection or semisolid oral preparations for skin, respiratory, gastrointestinal, and urinary ailments. Flavonoids, saponins, and alkaloids are responsible for pharmacological activities. Some medical applications of V. odorata in TPM have been proven by recent studies. However, more studies are needed to confirm these medicinal properties. Copyright © 2017 John Wiley & Sons, Ltd.
Purpose: Alzheimer disease (AD) is a progressive neurodegenerative disorder that is caused by neuroinflammation and oxidative stress. The present study aimed to characterize and then investigate the memory-enhancing potential of Viola odorata methanolic extract in lipopolysaccharide (LPS)-treated mice. Methods: V. odorata characterization was done by using the GCMS technique. Neuroinflammation was induced by the intracerebroventricular administration of LPS at a dose of 12 µg. Animals were divided randomly into six groups ( n = 10). Group I was normal control, which was given vehicle. Group II was disease control, which received LPS (12 µg) via the intracerebroventricular route. Group III was standard, which was administered with donepezil (3 µg) orally for 21 days. Groups IV-VI were the treatment groups, which were administered with the extract at 100, 200, and 400 mg/kg dose levels orally respectively for 21 days. Groups III-VI received LPS (12 µg) on the first day along with their treatments. During the treatment, the animals were assessed for memory retention by employing different behavioral paradigms namely elevated plus maze, passive avoidance, foot shock and open field. Various mediators [endogenous antioxidants, neurotransmitters, and acetylcholinesterase (AChE)] involved in the pathogenesis of AD were quantified by using the UV spectrophotometric method. Results: Extract-treated groups showed a remarkable improvement in cognitive impairment in all behavioral paradigms. Oxidative stress biomarkers, that is, superoxide dismutase, catalase, and glutathione were raised dose-dependently in the treatment groups with a dose-dependent decrease in the malonaldehyde and AChE levels in the brains of the treated animals. The treatment groups showed decreased levels of inflammatory biomarkers, that is, tumor necrosis factor-alpha, nuclear factor kappa light-chain enhancer of activated β-cells, and cyclo-oxygenase, which supports the therapeutic effectiveness of the treatment. Conclusion: Based on behavioral, oxidative stress biomarker, and neuroinflammatory data, it is concluded that V. odorata possesses memory-enhancing activity and may prove a beneficial role in the management of AD.
