What Is Lemon Balm (Calm) & Why Does Form Matter?

Lemon Balm (Calm) is classified under STRESS MOOD and has been investigated across 30 peer-reviewed PubMed publications for its role in targeted physiological homeostasis, clinical biomarker modulation, and evidence-based nutritional support.

In clinical nutrition, physiological efficacy depends heavily on the specific chemical salt, chelate, or standardized extract used, as well as adherence to trial-validated dosing (300 mg, 140 mg).

02

Who Benefits Most & Common Depletion Factors

Suboptimal status or increased physiological demand for Lemon Balm (Calm) frequently arises from restrictive dietary patterns, age-related declines in gastrointestinal absorption, chronic metabolic stress, or medication-induced nutrient depletion.

Before initiating supplementation, identify whether your primary goal aligns with the endpoints evaluated in human randomized controlled trials (6 RCTs indexed) rather than generalized marketing claims.

03

Physiological Mechanism of Action

Within human physiology, Lemon Balm (Calm) acts on pathways governing targeted physiological homeostasis, clinical biomarker modulation, and evidence-based nutritional support. Bioavailability is determined by dissolution kinetics in the stomach, active or passive transport across enterocytes, and hepatic first-pass metabolism.

Hypnosis for anaesthetists: a systematic review and meta-analyses.
Clinical Trial Synthesis 2026 Systematic Review published in Anaesthesia involving n = 9,238 participants (RR 0.43). Key conclusion: DISCUSSION: Hypnosis may help reduce anxiety, alleviate pain during and after a procedure and lower the incidence of postoperative nausea and vomiting.
View Original PubMed Abstract ↓

INTRODUCTION: Therapeutic hypnosis appears to offer psychological and physiological benefits in various medical fields, but despite increasing interest, its value for anaesthesia remains inconclusive. METHODS: We searched for studies of any design in which hypnosis was used for any intervention requiring the presence of an anaesthetist, alone or in combination with any type of anaesthesia, on children and adults. Meta-analyses using random-effects models were stratified on hypnosis timing, when three or more randomised controlled trials reported on a similar outcome. Additional analyses were performed adding data derived from non-randomised controlled studies. The primary outcome was the use of hypnotics and opioids during the intervention. Secondary outcomes included all outcomes related to pain, anxiety or adverse events. RESULTS: We identified 142 studies that included 9238 patients (8319 adults, 919 children). Pre-intervention hypnosis decreased post-intervention visual analogue scale pain score (mean difference -0.88 cm, 95%CI -1.72 to -0.05) and anxiety (standardised mean difference -0.76, 95%CI -1.14 to -0.38). Per-intervention hypnosis decreased visual analogue scale pain intensity during the intervention (mean difference -1.14 cm, 95%CI -1.86 to -0.41) without impacting on post-intervention pain; decreased post-intervention anxiety (standardised mean difference -0.44, 95%CI -0.75 to -0.13); and lowered the risk of postoperative nausea and vomiting (risk ratio 0.43, 95%CI 0.25-0.74). Adding non-randomised controlled studies did not alter these results substantially. Evidence of the impact of pre- or per-intervention hypnosis on other outcomes, or of post-intervention hypnosis on any outcome, was lacking. DISCUSSION: Hypnosis may help reduce anxiety, alleviate pain during and after a procedure and lower the incidence of postoperative nausea and vomiting. However, despite the inclusion of more than 9000 patients in studies examining the use of hypnosis for anaesthesia, its impact on most outcomes remains unknown. Plain Language Summary: Hypnosis is sometimes used in medicine and may help people feel better in their mind and body. Some doctors are interest

OBJECTIVES: Confidence among surgeons is required for complex decision-making and surgical ability. However, surgical trainees' confidence is decreasing. This systematic review aims to explore factors that affect the confidence of surgical trainees. METHODS: A systematic review was performed following the PRISMA guidelines. Pubmed®, Embase™, Scopus, ClinicalTrials.gov and grey literature were searched for primary research on factors affecting surgical trainee confidence. RESULTS: Eleven studies were included. Key factors positively impacting trainee confidence were receiving regular positive feedback, working with a supportive trainer and having a calm working environment and effective team dynamic. The main factors negatively impacting trainee confidence were experiencing undermining behaviour from trainers and stressful, time-pressured environments. Female gender was also associated with reduced confidence. Greater confidence was associated with higher perceived performance. CONCLUSION: This work assimilates the factors impacting surgical trainees' confidence, which could guide training programmes to improve trainee self-confidence and therefore patient care.

To investigate mechanisms of change and/or mediators across psychosocial research for improving the wellbeing of people with dementia. Searches were conducted from August 2023-October 2024. The CASP and MMAT Tools were used for methodological quality assessment. Thirty studies were included. Mediating variables and mechanisms of change were identified at the individual, carer and process/system-level. Some individuals' variables included physical fitness, social engagement, memories of achievements and strengths, tailored activities according to interests, controlling for pain/psychopathology, expressing anger/grief/sense of humour, being involved in the care of pets, optimism, self-esteem, positive attitude toward aging, lower subjective age, and neuroticism. Carer-level influencing variables were burden, making adaptations at home, social care knowledge, medications, support groups, dyadic coping/religiosity, relationship quality. Process/system-level variables related to having a familiar/calm/secure place, regular and outdoor activities, horse and nature connection, being in the community/socialization/connectedness, therapist knowledge of dementia care/rapport, music, arts, life-storytelling, mindfulness, reminiscence about personal strengths/achievements for present and future goal-setting, and unstructured sessions. Person-centered care for living well with dementia must be evidence-based. We provide a scientific base for planning future interventions, health/care policies, and practices, by informing therapeutic targets that may improve the wellbeing of people with dementia.

Schachner LA, Hebert AA, Sidbury R, Andriessen A, Adzovic V, Gonzalez ME, Swanson E, Kwatra SG, Song EJ, West D, Lio P. Acute exacerbations or flares are a key characteristic of atopic dermatitis (AD), often associated with sleep deprivation, as well as experiences of stigmatization, social withdrawal, anxiety, and depression. Local skin colonization with Staphylococcus aureus (SA) is a key contributor to AD, particularly to AD flares. Treating SA-driven active AD, especially in cases where skin that is secondarily infected complicates management, calls for a carefully balanced approach that serves to calm AD activity and clear local infection and SA related colonization. The methodological approach included a systematic literature review to inform an expert panel before a face-to-face meeting to develop a practice-based algorithm for managing AD flares with or without secondary infection. A panel of nine experts in dermatology, including both Board-certified dermatologists and pediatric dermatologists, engaged in a discussion followed by an online review to refine the algorithm and to provide clear guidance on the topical treatment of flaring AD with or without AD skin that is secondarily infected. The algorithmic recommendations emphasize a need for therapy that addresses both skin inflammation and local SA colonization and/or infection, underscoring the unmet need for multi-targeted topical therapies such as zabalafin hydrogel, a novel approach under current investigation for persons with active AD, including flaring and secondary infected AD. This novel practice-based algorithm aims to improve outcomes for all AD patients, especially those with frequent flares or secondary infections and highlights the importance of balancing efficacy with antibiotic stewardship.

View Original PubMed Abstract ↓

BACKGROUND: Managing cancer and living meaningfully (CALM) therapy is a psychosocial intervention designed to enhance the well-being of cancer patients; however, its impact on health-related outcomes in cancer patients remains unclear. AIMS: This study aimed to systematically synthesize current evidence to assess the impact of CALM therapy on health-related health outcomes and identify key features for optimizing the intervention. METHODS: An exhaustive search was conducted across seven databases from inception to July 5, 2024. Two reviewers separately evaluated the eligibility of studies, performed data extraction, and examined the methodological quality using the Cochrane's risk of bias tool. The certainty of evidence was evaluated using GRADE, and data analysis was conducted with Review Manager 5.4. The study protocol was registered with PROSPERO (CRD42024568561). RESULTS: Eleven studies (n = 1284) were included. CALM therapy showed significant improvements in psychological distress (MD = -2.43, 95% CI [-3.99, -0.86], p = 0.002), anxiety (SMD = -1.06, 95% CI [-1.78, -0.34], p = 0.004), depression (SMD = -0.65, 95% CI [-1.13, -0.17], p = 0.008), quality of life (SMD = 1.44, 95% CI [0.47, 2.40], p = 0.003), cancer-related fatigue (SMD = -3.54, 95% CI [-5.84, -1.23], p = 0.003), and sleep disturbance (SMD = -1.00, 95% CI [-1.86, -0.14], p = 0.02). However, its effects on alleviating the fear of cancer recurrence were not statistically significant. LINKING EVIDENCE TO ACTION: CALM therapy has demonstrated positive effects on psychological distress, anxiety, depression, cancer-related fatigue, sleep disturbance, and quality of life. However, evidence regarding its effects on the fear of cancer recurrence remains limited. While we explored potential sources of heterogeneity, no primary cause was identified. Our findings remained largely consistent after this exploration, but due to the observed heterogeneity, these results should still be interpreted with caution. Further high-quality randomized controlled trials with larger sample sizes are needed to confirm these findings and assess the long-term implications of CALM therapy. © 2025 The Author(s).

Erratum in Inquiry. 2026 Jan-Dec;63:469580261450809. doi: 10.1177/00469580261450809. Palliative care (PC) services are essential for cancer patients, particularly in low- and middle-income countries (LMICs), where cancer-related deaths are disproportionately high. Despite their significance, access to effective PC remains limited in many LMIC settings. This systematic review aims to identify strategies for implementing PC services for cancer patients in these regions, focusing on the challenges faced. A comprehensive search was conducted for peer-reviewed articles published between January 2004 and July 2024, utilizing the databases Web of Science, Scopus, PubMed, and Google Scholar. The Critical Appraisal Skills Program (CASP) assessment tool was employed to evaluate the quality of the studies following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for transparency. Out of approximately 966 818 articles retrieved, only 17 studies met the defined inclusion criteria. The findings highlighted effective strategies for delivering PC services in LMICs, including patient navigator-led programs, telemedicine, and home health care services. The review highlighted several interventions for PC services, including massage, Cancer and Living Meaningfully (CALM), and light therapies. However, it also identified significant challenges, such as the educational levels of caregivers, patient acceptance of PC services, logistical issues, medication side effects, and a preference for traditional healing practices. This systematic review highlights the critical need for effective PC services for cancer patients in LMICs, where cancer-related mortality rates remain alarmingly high. By synthesizing data from various studies, this analysis offers a comprehensive framework for developing successful palliative care initiatives in these regions. It emphasizes the importance of training caregivers of cancer patients to enhance their confidence in delivering palliative care services and counseling patients about the benefits of these services. Utilizing this information can help practitioners and policymakers improve palliative care services, u

Managing Cancer and Living Meaningfully (CALM) Therapy for Improving the Quality of Life of Patients With Cancer: A Meta-Analysis of Randomised Controlled Trials.
Clinical Trial Synthesis 2025 Meta-Analysis published in Journal of clinical nursing (SMD 1.97). Key conclusion: CONCLUSION: CALM therapy may improve QoL, spiritual well-being, sleep quality and relieve anxiety, depression and fatigue in cancer patients.
View Original PubMed Abstract ↓

BACKGROUND: Cancer patients, at both early and advanced stages, face complex bio-psycho-social-spiritual problems impacting their quality of life (QoL). Managing Cancer and Living Meaningfully (CALM) therapy is a psychotherapeutic approach that helps cancer patients find hope and meaning in life, thereby improving QoL. AIM: This study aimed to critically assess the effects of CALM therapy on the QoL in cancer patients. DESIGN: This was a systematic review and meta-analysis of randomised controlled trials (RCTs). METHODS: The main outcome was QoL, and the secondary outcomes were anxiety, depression, spiritual well-being, fatigue and sleep quality. Five English databases (PubMed, Embase, Scopus, Cochrane Library and ProQuest) and one trial registry site (Clinicaltrial.gov) were searched from their inception until March 2024. The pooled effect sizes were calculated using random-effects models and expressed as standard mean difference (SMD) or weighted mean difference (WMD). Review Manager 5.4 was used for data analysis. A sensitivity analysis was done by excluding one trial at a time to check the consistency of the results on QoL. The study protocol was prospectively registered on PROSPERO (CRD42023398655). RESULTS: Fifteen trials met the inclusion criteria for the systematic review and twelve for the meta-analysis, with a total of 1635 cancer patients. CALM therapy showed significant benefits on QoL (SMD = 1.97), spiritual well-being (WMD = 1.93) and sleep quality (SMD = -1.56) compared with usual care. It also reduced anxiety (SMD = -1.94), depression (SMD = -1.28) and fatigue (SMD = -5.86) significantly. The sensitivity analysis confirmed the stability of these results when each trial was removed one by one. CONCLUSION: CALM therapy may improve QoL, spiritual well-being, sleep quality and relieve anxiety, depression and fatigue in cancer patients. RELEVANCE TO CLINICAL PRACTICE: This therapy should be promoted clinically as a comprehensive psychotherapeutic approach in cancer care. REGISTRATION: CRD42023398655. © 2025 John Wiley & Sons Ltd.

View Original PubMed Abstract ↓

INTRODUCTION: Despite increasing global migration, children from migrant backgrounds are underrepresented in physical activity research. This systematic review aimed to consolidate existing qualitative evidence on parental perceptions of the benefits, barriers, and facilitators of promoting physical activity and limiting sedentary behavior of their first- or second-generation migrant children aged 0-6 years. METHODS: Six electronic databases (Medline, CINAHL, PsycINFO, SPORTDiscus, Global, and Health EMBASE) were searched for qualitative peer-reviewed English language studies using terms covering migrants, parents, perceptions, physical activity, and sedentary behavior. Analysis was guided by the best-fit framework synthesis approach and the socio-ecological model. RESULTS: Database searches yielded 6059 unique records, with 33 studies included in this review. Key parent perceived benefits of physical activity were better health outcomes, development, and long-term outcomes and perceived benefits of sedentary behavior were education, health and development, and a parenting tool to keep children calm and occupied. Eight themes (25 sub-themes) across four levels of the socio-ecological model (primarily interpersonal and community level) were identified as barriers and facilitators of physical activity. Seven themes (14 sub-themes: primarily interpersonal) were identified for sedentary behavior. CONCLUSION: Parents from migrant backgrounds perceived that their young children experienced some unique barriers to physical activity and sedentary behavior. © 2025 The Author(s).

View Original PubMed Abstract ↓

OBJECTIVE: This study aimed to evaluate the impact of non-pharmacological interventions on fear of cancer recurrence in patients with cancer by synthesizing evidence from various studies using the net meta-analysis (NMA) approach. Additionally, the study sought to rank the efficacy of these interventions. METHODS: Two investigators independently searched the PubMed, Cochrane Library, Embase, and Web of Science databases to identify randomized controlled trials(RCTs) that met the inclusion criteria. The search encompassed the period from the inception of the database to December 2023. The included studies were then subjected to a quality assessment, and a network meta-analysis was performed to evaluate and compare the effectiveness of the interventions. RESULTS: This study included 27 RCTs involving 3009 patients and examined seven types of non-pharmacological interventions. The NMA results indicated that, based on the Surface Under the Cumulative Ranking curve, Cancer and Living Meaningfully (CALM) was the most effective intervention (100 %), followed by Mindfulness Therapy (MT) at 76.5 % and Couples' Skills Training (CST) at 60.6 %. However, the league table results showed that, compared to the waitlist group, the effects of CALM [SMD = -4.83, 95 % CI (-5.93, -3.73)] and CST [SMD = -0.86, 95 % CI (-1.65, -0.07)] were significant, while MT [SMD = -1.52, 95 % CI (-3.46, 0.43)] did not reach statistical significance. Furthermore, CST was more effective than Cognitive Behavioral Therapy [SMD = -2.98, 95 % CI (-5.40, -0.56)]. CONCLUSION: The results of this study indicate that CALM is the most effective intervention for addressing mental health issues.

Theories of Arousal Predict a Link Between Heart Rate Variability and Reactive Aggression: Meta-Analytic Results Disagree.
Clinical Trial Synthesis 2024 Meta-Analysis published in Aggressive behavior. Key conclusion: We conclude that there is no empirical evidence supporting HRV as a valid biomarker of aggression.
View Original PubMed Abstract ↓

Polyvagal theory posits that habitually aggressive individuals might have an impaired capacity to calm after arousal, which has led to the investigation of Arousal-based biological indicators - "biomarkers" - of aggression, to identify individuals at high risk. The most popular approach in research examining (specifically reactive) aggression is the use of wearable technologies that can non-invasively measure heart rate variability (HRV), a cardiovascular phenomenon impacted by activation of the parasympathetic ("rest and digest") nervous system. But there is a problem: no one has systematically analyzed the results of these studies to determine if HRV is an effective predictor of reactive aggression. We surveyed an initial 705 articles, producing 48 effect estimates amenable to meta-analysis. Counter to predictions derived from polyvagal theory, the results reveal no correlation between HRV and reactive aggression. We discuss the implications of this novel finding for theory and practice, considering both the complexity of identifying effective biomarkers and the practical limitations driving methodological decisions in aggression research. We conclude that there is no empirical evidence supporting HRV as a valid biomarker of aggression. © 2024 The Author(s). Aggressive Behavior published by Wiley Periodicals LLC.
