The purpose of this article is to determine whether the positive association between social support and well-being is attributable more to an overall beneficial effect of support (main-or direct-effect model) or to a process of support protecting persons from potentially adverse effects of stressful events (buffering model). The review of studies is organized according to (a) whether a measure assesses support structure or function, and (b) the degree of specificity (vs. globality) of the scale. By structure we mean simply the existence of relationships, and by function we mean the extent to which one's interpersonal relationships provide particular resources. Special attention is paid to methodological characteristics that are requisite for a fair comparison of the models. The review concludes that there is evidence consistent with both models. Evidence for a buffering model is found when the social support measure assesses the perceived availability of interpersonal resources that are responsive to the needs elicited by stressful events. Evidence for a main effect model is found when the support measure assesses a person's degree of integration in a large social network. Both conceptualizations of social support are correct in some respects, but each represents a different process through which social support may affect well-being. Implications of these conclusions for theories of social support processes and for the design of preventive interventions are discussed. During recent years interest in the role of social support in health maintenance and disease etiology has increased (e.g.

The many of the modern medicines are obtained from plant source in earlier days. Ayurvedic and siddha system of medicine use herbal derived products for many illnesses based on their folkloric and traditional claims. Herbal research conducted earlier was aimed at isolating active principles and there by attributing cause-effect relationship on the herbal material. Since the possibility of losing the activity of the plant during extraction and the huge cost involved in isolating the active principle, World Health Organization, has recommended 'reverse pharmacology' where scientific validation for the existing drugs was attempted. Public are now using alterative system of medicine as an add on therapy to modern medicine. This probably might result in herbal-allopathic drug interaction which is to be monitored through herbal pharmacovigilance.

This review highlights consistent patterns in the literature associating positive affect (PA) and physical health. However, it also raises serious conceptual and methodological reservations. Evidence suggests an association of trait PA and lower morbidity and of state and trait PA and decreased symptoms and pain. Trait PA is also associated with increased longevity among older community-dwelling individuals. The literature on PA and surviving serious illness is inconsistent. Experimentally inducing intense bouts of activated state PA triggers short-term rises in physiological arousal and associated (potentially harmful) effects on immune, cardiovascular, and pulmonary function. However, arousing effects of state PA are not generally found in naturalistic ambulatory studies in which bouts of PA are typically less intense and often associated with health protective responses. A theoretical framework to guide further study is proposed.Keywords: positive affect, mortality, morbidity, health, emotions A cheerful heart is good medicine.-Proverbs 17:22Self-help books, popular magazines, and Sunday newspaper supplements have suggested for years that positive affect (PA) can improve people's health. However, this hypothesis has been relatively ignored in research on psychological predictors of health. For example, a search of PsycINFO revealed that there are over 20 times more studies on depression and health than there are on happiness and health. Although the recent interest in "positive psychology" has focused attention on the potential benefits of positive feelings (e.g., Seligman & Csikszentmihalyi, 2000), there has been little critical discussion of the evidence linking PA to physical health. In this article, we review the literature examining the association between measures of PA and markers of physical health status, examine the conceptual and methodological weaknesses in the existing literature, and discuss how PA could get "under the skin" to influence health. PAWe define PA as the feelings that reflect a level of pleasurable engagement with the environment (Clark, Watson, & Leeka, 1989) such as happiness, joy, excitement, enthusiasm, and contentment. These can be brief, longer lasting, or more stable traitlike feelings. Although some use the terms affect, mood, and emotion to distinguish duration, these uses are not applied consistently in the literature, and thus we use these terms interchangeably. We, however, distinguish between studies using measures that assess more stable disposition-like PA, which we refer to as trait PA, and those measuring or manipulating relatively short-term bouts of positive emotions, which we refer to as state PA.To date, reviews examining associations between positive psychological constructs and health outcomes have been broad in scope, including traits such as self-esteem, extraversion, purpose, mastery, and optimism along with PA (Lyubomirsky, King, & Diener, 2005;Ryff, 2003;Salovey, Rothman, Detweiler, & Steward, 2000;Zautra, 2003). Hence, it has been difficult to separate t...
