Stress is a multifactorial stimulus that elicits responses at emotional, cognitive, behavioral and also at physiological levels. Thus the approach to manage stress should also be multifactorial. Among the herbal approaches, traditionally polyherbal formulations are used in Indian medicine. Present study on StressCare capsules was a Double Blind, Placebo Controlled, Clinical Study to evaluate its Efficacy and Safety in 100 volunteers presenting with clinical symptoms of stress and irritability. On entry, a detailed medical history was obtained to ascertain the presence of anxiousness followed by complete physical and psychological examination. All the people were randomly divided into StressCare and placebo groups, and people from both the groups received either StressCare or placebo for a period of 8 weeks, in a dose of 2 capsules twice daily, orally. Those involved in the study were evaluated clinically on entry at 4 weeks and at end of 8 weeks. All the subjects were clinically evaluated at regular intervals and statistical analysis was performed between the groups. Study results indicate that StressCare is safe and effective in the management of mild occasional stress and irritability as compared to placebo.

Stress is a common buzz word in the modern lifestyle and related health concerns. When people reach out for help, they are often dealing with circumstances, situations, and stressors in their lives that leave them feeling emotionally and physically overwhelmed. This is because people feel that their resources or skills are not up to the mark to deal with the high levels of stress they are experiencing. Dr. Walter B. Cannon, a physiologist described the meaning of “stress” in terms of “fight or flight response” as a series of involuntary physiological and biochemical changes that prepare you to deal with threats of danger. This response was critical to the survival of primitive humankind when requiring quick bursts of energy to fight or flee predators such as the saber-toothed tiger .
Basically, stress is defined in at least three ways as per the context. First definition states that more the stress or stimulus, the bearer either human or other physical thing, will succumb to it. When the stimulus is too great, the collapse becomes inevitable. This is in line with Oxford dictionary’s definition of stress; “to subject (a material thing, a bodily organ, a mental faculty) to stress or strain; to overwork, fatigue.”
Selye (1956) gave a physiological response based definition of stress. It measured stress in terms of body’s stage wise response to stress from creating an internal alert till stage of exhaustion in health. This duration of stages gives the scope for handling the stress accordingly .
Third definition of stress proposes a comprehensive explanation including stimulus based and response based definitions and regarding stress as a dynamic process of both. Lazaraus and Folksman (1984) advocated this definition which emphasizes the involvement of cognitive, emotional and behavioral factors .
Thus, Definitions of stress provide only a snapshot of this dynamic process. In the Encyclopaedic Dictionary of Psychology this dynamic process is defined as “the way in which people realize and identify their problems, how they react to them and attempt to cope with them and the ‘cost’ of doing so” (Harre and Lamb) [4,5].
Although some stress is a natural and inevitable part of our lives, feeling burdened or unable to cope can be problematic and can affect the mental and physical well-being .
Constantly being exposed to stressful situations can be overstimulating and if we are constantly feeling stressed, we may begin to feel unable to manage the problems at hand. In order to avoid situations in which we feel “overloaded,” we must first identify what stresses us, what our threshold for stress is, and how we can most effectively manage stressful situations. No one event, regardless of how traumatic, can be detrimental to health . Among various methods and techniques suggested for minimizing the effects of stress to individuals, some noteworthy are yoga, exercises, behavioral therapies, relaxation techniques, deep breathing, massages and others. These are non-drug therapies aimed to relieve stress. Alternative measures also include herbal preparations which are traditionally known to be helpful.
StressCare capsule is a polyherbal formulation that might help in coping to stressful conditions in healthy individuals.
Material and Methods
The study was aimed to evaluate the safety and efficacy of Stress Care Capsule in 100 individuals presenting with mild occasional Stress and irritability related parameters like loss of appetite, indigestion, weakness, occasional stress, fatigue, mood swings, occasional sleep disturbances, and occasional bowel disturbances in a prospective double blind placebo controlled study design. This study was conducted at Kolkata Nursing Home, Aatghara, Rajarhat Road, Rajarhat Gopalpur, Kolkata.
Subjects who are above 18 years of age group were selected as per the subject selection criteria. Subjects with severe psychiatric disorder, pregnant and breastfeeding women, individuals with severe Hepatic/ cardiac/ mental disorder, subjects with history of alcohol or smoking abuse were excluded from the study. Individuals unwilling to provide informed consent or abide by the requirements of the study were also excluded from the study. On admission into the study, informed consent was obtained from subjects after explaining the nature of the study. The subjects were free to opt out from the study, if they desired so. The subjects were randomly assigned in two groups, A and B. Subjects in Group A received StressCare capsule in the dosage of Two capsule twice a day with meals for 8 weeks while the subjects in Group B received identical placebo in the same dosage. No other supplements were administered to these subjects.
Demographic data of subjects on entry is given in the Table 1. All the subjects were evaluated at the entry, end of Week 4 and end of Week 8. Detailed clinical information was collected from each subject about stress and related health concerns. General physical examination, systemic examination and laboratory investigations were recorded on a Case Report Form at all intervals. Clinical symptoms were assessed as per the scoring i.e., Nil (0), Mild(1), Moderate(2) and Severe(3) and overall clinical assessment was defined as cured, improved and unchanged. Hematological parameters like Hemoglobin, Total count, Differential count, ESR, Platelet count, Biochemical parameters like Random blood sugar, SGPT and Serum creatinine were carried out at entry and at the end of the study.

Adverse events were to be reported or observed by the subjects with the information about the severity, date of onset, duration and the action taken. Relation of the adverse events to study interventions was predefined as certain, probable, possible and unlikely. For subjects withdrawing from the study, efforts were made to ascertain the reason for dropout. Non-compliance (defined as failure to take less than 80% of the intervention) was not regarded as intervention failure but the reason for non- compliance were noted.
The primary endpoint was defined as overall clinical improvement in stress and irritability related condition like loss of appetite, indigestion, weakness, occasional stress, fatigue, mood swings, occasional sleep disturbances, occasional bowel disturbances, and sense of well being.
Statistical analysis performed between the groups using Mann Whitney test for all parameters except for weight gain which was analysed using unpaired t-test. For blood pressure, hematological and biochemical parameters, analysis was performed using paired t test. Statistical analyses were performed using Graphpad Prism software Version 6.07, San Diego, California, USA.

In this double blind, placebo-controlled study, the safety and efficacy of StressCare in mild occasional stress and related conditions were investigated. Improvement in stress and stress related condition following 8 weeks of StressCare treatment in comparison with placebo was noted. Since StressCare capsules consists of those herbal ingredients help to relieve stress, scavenge free radicals and toxins, improve immune responses and support cardiac and nervine functioning, it facilitates in protecting from further stress and possible tissue damage. Thereby StressCare helps to improve normal physiological immunity and tissue responses required for cellular regeneration and repair, thus reviving the physical capacity, enhanced ability to digest the ingested food and promote the sense of well-being.
This clinical study indicates good clinical efficacy of StressCare Capsules in promoting sense of well-being and improvement in mild occasional stress and irritability related clinical parameters like occasional loss of appetite, mild indigestion, occasional weakness, occasional stress, mild fatigue, mild mood swings, occasional sleep disturbances, occasional bowel disturbances, and sense of well-being. Maintenance of normal blood pressure and laboratory parameters in the normal range suggest that StressCare capsule is well tolerated and safe for human use. There were no adverse events either reported or observed in the clinical study. Thus it can be concluded that StressCare is safe and effective in the management of mild occasional stress and irritability.
