Worldwide, cardiac disorders constitute a leading cause of morbidity and mortality. Cardiac disorders include high blood pressure, atherosclerosis, arrhythmia, congestive heart failure, stroke etc. Increase in incidence of cardiac disorders is a manifestation of lifestyle changes. Although modern drugs are effective in preventing the cardiac disorders, their use is often limited because of their side effects and adverse reactions. Use of herbal drugs is not only cost effective but also has better safety and efficacy. The World health Organisation (WHO) estimates that about 80% of the population living in the developing countries still relies on herbal drugs for their primary healthcare needs. Today, ethno-botanical and ethno-pharmacological studies of medicinal plants continue to attract investigators for research work globally. Aim of this current review to explain herbal phytoconstituents therapy on the basis-“Type of disorder, Mode of action and Pharmacological screening model”, which could be an informatics approach in management of cardiac...

Herbal extracts are primarily added to the cosmetic formulations due to several associated properties such as antioxidant, anti inflammatory, antiseptic and antimicrobial properties. Even today, people in rural and urban areas depend upon herbs for traditional cosmetics. Information on the herbal cosmetics was collected via electronic search (using pub med, scifinder, Google Scholar and web of science) and library search for articles published in peer-reviewed journals. Furthermore, information also was obtained from some local books on ethnopharmacology. The herbal extracts, as a whole or part, have been used for various ailments of the skin, hair, and dental care for overall appearance. Cosmetics alone are not sufficient to take care of skin and others body parts, it requires association of active ingredients to check the damage and ageing of the skin. Herbal cosmetics have gained much popularity among the population. Herbal cosmetics products claimed to have efficacy and intrinsic acceptability due to routine use in daily life and avoid the side effects which are commonly seen in synthetic products. Due...

Phenolic compounds are group of molecules which contain different families of secondary metabolites. Phenolic compounds, secondary metabolites, are abundantly found in plants and are mostly categorized into two major groups: non-soluble compounds and soluble compounds. Stilbenes which come under the category of soluble compounds of phenolics are small molecules, ranges in their weight from ~200 to 300 g/mol and are found in diverse plants. These compounds are produced in plants via phenylpropanoid pathway. Under unfavourable conditions such as microbial or viral attack, ultraviolet light exposure and disease in plants, stilbenes are synthesized and act as natural agents to protect plants. Piceatannol, a natural stilbene, is found in different plant species and is beneficial for human health. It possesses various pharmacological properties such as antioxidant, antitumor, anti-inflammatory and anti-carcinogenic activities. This review paper focuses on piceatannol, its sources, chemical synthesis mechanism, production and its useful applications in various...

As described by the world health organization (WHO), depression is the most common and serious disorder leading to suicide. Numbers of synthetic drugs are available for the treatment of this fatal disease, but are associated with serious complications. A wide diversity of animal models has been used to examine antidepressant activity. These range from relatively simple models sensitive to acute treatment, to highly sophisticated models. The number of validated animal models for affective disorders is large and still growing. A basic understanding of the underlying disease processes in depression is lacking, and therefore, recreating the disease in animal models is not possible. For the animal model of depression, the relevance, reliability and reproducibility in laboratories need to be focused, currently used models of depression attempt to produce quantifiable correlates of human symptoms in experimental animals and the animal modeling remains a potentially important approach towards understanding neurochemical and neurobiological mechanisms in depression. Animal models of depression attempt to represent some aspect of the etiology, symptomatology and treatment of the...

Hyaluronic acid is an important naturally occurring polysaccharide present in extracellular matrices. The network-forming, viscoelastic and the charge characteristics of hyaluronic acid are important to many biochemical functions of living tissues. Its involvement in many diseases such as cancer, arthritis and osteoporosis, and the fact that it has specific protein receptors present on the cell surfaces, has given new impetus in drug design and synthesis of hyaluronic acid-drug conjugates. As a general arrangement, the review will focus on structure and conformation of hyaluronic acid, its chemistry and chemical methodologies that have led to a number of important hyaluronic-drug...
