The seed of Chia (Salvia hispanica L.), originating in Mexico, is included in the cereals group, is considered a functional food. Its physicochemical composition and nutritional properties make it a significant source of fiber, carbohydrates, proteins, minerals, essential amino acids, antioxidants and is rich in polyunsaturated fatty acids (PUFAs). The objective of this study was to gather information that relates Chia seed composition to the prevention, treatment and control of some pathologies, such as obesity, dyslipidemia, cardiovascular disease and diabetes. This review study used the databases Medline/Pubmed, Lilacs, Scielo, a bibliographic collection of the Federal University of Campina Grande and materials from the national and international health committees, from articles published in the last 20 years. Sixty references were found, of which 43 were included in this study, excluding only those that did not have relevant aspects of the proposed theme. Therefore, when adding Chia seeds to the diet, it is possible to notice an improvement in parameters such as blood pressure (BP), lipid profile, glycemic index (GI), increased satiety sensation and delayed gastric emptying, which are direct indicators of these diseases And consequently the quality of life. Thus, Chia seed is only an auxiliary, and healthy living habits are also necessary.

Anacardium occidentale is a native plant from Brazilian Northeast popularly known as cashew tree, having great socioeconomic importance for this region, due to the great popularity of its fruit and its medicinal properties, the example antimicrobial activity. The present study had as objective to make a bibliographical survey about the antimicrobial activity of A. occidentale against strains of bacteria and fungi. We used the databases Scielo, PubMed, Lilacs and Periódicos Capes, in which 110 articles were analyzed and only 48 were selected. From the data obtained in the literature, it was observed that the bark of the stem, leaves, flowers and the own fruit of A. occidentale present antimicrobial activity against Gram-positive and Gram-negative bacteria and fungi of the genus Candida. Thus, A. occidentale presents as a potential species for the research and development of possible herbal medicines to combat bacterial and fungal infections.

A mastite bovina é a doença que mais onera a pecuária leiteira, por tratar-se de uma doença plurietiológica e multifatorial, e altamente contagiosa. O uso de antimicrobianos ainda é a principal estratégia para controle e tratamento; todavia, a resposta à antibioticoterapia e o aumento de resistência bacteriana, bem como, a presença de resíduos antimicrobianos no leite, tem sido foco de estudos para definir quais os fatores responsáveis por falhas na terapia; além do estudo de várias substâncias extraídas de plantas como alternativas terapêuticas. Este artigo foi elaborado por meio de pesquisa bibliográfica, com o objetivo de abordar o uso compostos naturais extraídos de plantas sobre bactérias isoladas em mastite bovina. Várias substâncias extraídas de plantas têm sido estudadas, para avaliação de suas atividades farmacológicas; gerando dados importantes e ótimos resultados. Grande destaque tem sido dado aos óleos essenciais, substâncias complexas voláteis, lipofílicas, odoríferas e líquidas, oriundas do metabolismo secundário de vegetais; e têm despertado interesse como alternativa ao tratamento da mastite bovina. Diversos trabalhos têm comprovado a eficácia de compostos naturais extraídos de plantas sobre bactérias isoladas em mastite bovina; apresentando como estratégia terapêutica promissora; apesar de grande parte da diversidade genética vegetal do Brasil ainda permanecer oculta à ciência, merecendo a avaliação de suas propriedades farmacológicas.   Palavras-chave: compostos naturais; pecuária leiteira; antimicrobiano.   Abstract The bovine mastitis it’s the disease that most burden the dairy farming, due to the fact that it has many etiological reasons, and it is highly contagious. The use of antimicrobials is still the main strategy to control and treat this disease. However, the response to antibiotic treatment, the increase of bacterial resistance and the containing of antimicrobials residues in the milk as well, has been the main spot for researches to define which were the causes of failure in the treatment; also mentioning researches of many substances extracted from plants as alternative treatments. This article has been written using bibliographic survey with the objective to discuss the usage of natural compounds extracted from plants over isolated bacteria of cattle mastitis. Many substances taken from plants have been studied for the proper evaluation of their pharmacological usage, resulting in the achievement of important data and great results. A considerable highlight has been given to the essential oils, complex, volatile, lipophilic, odoriferous and liquid substances originated from the secondary metabolism of plants; they have risen the interest as an alternative to the treatment of cattle mastitis. Several researches have proved the efficiency of natural compounds extracted from plants over isolated bacteria of cattle mastitis; showing a new promising therapeutic strategy; although most of the vegetal genetic diversity in Brazil is still hidden to science, thus deserving a proper evaluation of their pharmacological properties.   Keywords: natural compounds; dairy farming; antimicrobial.
