Plantas medicinais no tratamento de ansiedade e depressão: Uma revisão

Há uma grande diversidade de plantas no Brasil, e muitas delas, ao serem estudadas, apresentam elevado teor nutricional, presença de antioxidante, entre outras propriedades, podendo ter um potencial farmacológico significativo e consequentemente gerando aplicações em diversas áreas como saúde, cosmética e culinária. As plantas medicinais são usadas por grande parte da população mundial, como um recurso medicinal alternativo para o tratamento de diversas doenças, visto que em muitas comunidades, representam um recurso mais acessível em diversos sentidos em relação aos medicamentos alopáticos. Destaca-se a utilização das plantas medicinais para fins terapêuticos, em que muitas atividades biológicas conferidas às plantas foram demonstradas, dentre elas a ação no sistema nervoso central, sendo utilizadas para o tratamento e/ou prevenção de transtornos psicossociais como ansiedade e depressão. Sendo assim, o presente estudo tem como objetivo realizar uma revisão bibliográfica sobre as plantas medicinais mais utilizadas no tratamento da ansiedade e depressão. Verificou-se que nos tratamentos, as plantas medicinais e os fitoterápicos são vistos como uma alternativa viável para o tratamento dos quadros de ansiedade e depressão, visto que possuem menos efeitos colaterais. Sendo assim, a presente pesquisa revisou as espécies: Hypericum perforatum L.; Passiflora incarnata L.; Melissa Officinalis L.; Chamomilla recutita L.; Piper methysticum G.; Erythrina verna; Humulus lupulus L. e Crataegus oxyacantha L. Foi possível apresentar a efetividade de todas as espécies citadas, com as descrições encontradas em estudos da literatura.

Spectral analyses of fresh and dry Hypericum perforatum L. Effects with colloidal nano silver 30 ppm

Spectral analyses of 1% water extracts of fresh and dry Hypericum perforatum L. and 1% dry H. perforatum with colloidal nano silver (NSPs) 30 ppm were conducted. The nano silver is standardised and patented by the Swiss company Evodrop. Non-equliblrium energy spectrum (NES) and Differential non-equliblrium energy spectrum (DNES) methods were used for the spectral analysis. A comparative analysis of 1% extracts of fresh and dry H. perforatum was performed in order to determine the local extremums for effects of nerve tissue conductivity at (-0.1112) eV, anti-inflammatory (-0.1212) eV, anti-tumor effects (-0.1387) eV. The results showed stimulating effect on the nervous system and improvement of nerve conduction (local extremums E=-0.1112 eV)(?=11.15 ?m) (?=897 cm-1), as well as anti-inflammatory effect (E = -0.1212 eV)( ?=10.23 ?m) (?=978 cm-1) and inhibition of development of tumor cells at a molecular level (E=-0.1387 eV) (?=8.95 ?m) (?=1117 cm-1). It was found that clusters of 16 and 15 water molecules are formed in the water herbal extracts of fresh H. perforatum and of dry H. perforatum with AgNPs 30 ppm. The fresh plant showed better results then the dry one. The addition of colloidal nano silver 30 ppm led to better results of the drug.

Evaluation of Antimicrobial Activity of Several Medicinal Plants Against Clinically Isolated Staphylococcus Aureus from Humans and Sheep

Background: Continuous and indiscriminate use of chemical drugs causes an important phenomenon of resistance to microorganisms. Accordingly, the effect of medications is minimized or offset, increasing drug use and the need to study mixtures with more latest and powerful formulations. On the other hand, it has been reported that many plants essential oils have a significant inhibitory effect on pathogenic microorganisms. Objectives: This study aimed to evaluate the antimicrobial activity of some curative herbs against some clinical bacteria of humans and sheep. Methods: The leaves of chicory (Cichorium intybus L.), Hypericum perforatum L., Lavandula angustifolia, Thymus vulgaris L., and Taxus baccata L. were collected and determined in the botanical laboratory of the University of Zabol. Forty grams of dried leaves was used in 400 mL of ethanol (96%) to prepare the ethanolic extract. DPPH was used to determine the activity of reactive oxygen species (ROS) trapping. The antimicrobial effects were studied by the disk diffusion (6 mm) method in Müller-Hinton agar medium according to the method by Bauer et al. Results: The minimum inhibitory concentrations (MICs) of chicory, thyme, H. perforatum, French lavender, and yarrow extracts in human clinical Staphylococcus aureus were 6.25, 12.5, 3.1, 25, and 6.25 ppm, respectively, but, in sheep, clinical S. aureus, were 12.5, 6.25, 3.1, 12.5, and 25 ppm, respectively. The minimum bactericidal concentrations (MBCs) of chicory, thyme, H. perforatum, French lavender, and yarrow extracts in human clinical S. aureus were 12.5, 25, 6.25, 50, and 12.5 ppm, respectively, but, in sheep clinical S. aureus, were 25, 12.5, 6.25, 25, and 50 ppm, respectively. The most effective extract in inhibiting the growth of S. aureus was the H. perforatum L. extract with an 8.9-mm diameter growth inhibition zone. Conclusions: Regarding the side effects of artificial medications and antimicrobials, as well as the significant influence of healing herb extracts used in this study, it was found that H. perforatum was the most effective plant against S. aureus. It should be noted that plant extracts were more effective in human clinical S. aureus than in sheep clinical S. aureus.
