Camellia Species

Medicinal plants have been used since antiquity to cure illnesses and injuries. In the last few decades, natural compounds extracted from plants have garnered the attention of scientists and the Camellia species are no exception. Several species and cultivars are widespread in Asia, namely in China, Japan, Vietnam and India, being also identified in western countries like Portugal. Tea and oil are the most valuable and appreciated Camellia subproducts extracted from Camellia sinensis and Camellia oleifera, respectively. The economic impact of these species has boosted the search for additional information about the Camellia genus. Many studies can be found in the literature reporting the health benefits of several Camellia species, namely C. sinensis, C. oleifera and Camellia japonica. These species have been highlighted as possessing antimicrobial (antibacterial, antifungal, antiviral) and antitumoral activity and as being a huge source of polyphenols such as the catechins. Particularly, epicatechin (EC), epigallocatechin (EGC), epicatechin-3-gallate (ECG), and specially epigallocatechin-3-gallate (EGCG), the major polyphenols of green tea. This paper presents a detailed review of Camellia species’ antioxidant properties and biological activity.

Over the last years, great interest has arisen concerning plant stilbenes, especially resveratrol, which has a whole spectrum of positive biological activities. In this study, we investigated the presence of resveratrol monomers (trans- and cis- form) and naturally occurring derivatives of fraas-resveratrol (piceid, astringin and isorhapontin) in phenolic extracts of twenty medicinal plants traditionally used in Croatian folk medicine. The investigated compounds were present in the samples, in free form or as glucosides, and the highest share was found in immortelle, common yarrow and Lamiaceae plants. The obtained results indicate that biological activity of selected medicinal plants can be related to the presence of this valuable group of phytochemicals.

Mitigate Climate Change

AbstractThe recent publication of a World Scientistsʼ Warning to Humanity highlighted the fact that climate change, absent strenuous mitigation or adaptation efforts, will have profound negative effects for humanity and other species, affecting numerous aspects of life. In this paper, we call attention to one of these aspects, the effects of climate change on medicinal plants. These plants provide many benefits for human health, particularly in communities where Western medicine is unavailable. As for other species, their populations may be threatened by changing temperature and precipitation regimes, disruption of commensal relationships, and increases in pests and pathogens, combined with anthropogenic habitat fragmentation that impedes migration. Additionally, medicinal species are often harvested unsustainably, and this combination of pressures may push many populations to extinction. A second issue is that some species may respond to increased environmental stresses not only with declines in biomass production but with changes in chemical content, potentially affecting quality or even safety of medicinal products. We therefore recommend actions including conservation and local cultivation of valued plants, sustainability training for harvesters and certification of commercial material, preservation of traditional knowledge, and programs to monitor raw material quality in addition to, of course, efforts to mitigate climate change.

The SASAMBO (Sasak, Samawa, Mbojo) tribe has a variety of medicinal plants. The abundance of SASAMBO tribal medicinal plants can be used in learning the natural product chemistry which are expected to support traditional health tourism on the islands of Lombok and Sumbawa. Natural product chemistry examines the chemical content associated with the efficacy of a medicinal plant. This linkage can provide scientific support for the use of SASAMBO traditional medicinal plants. The method used in this research is the study of literature and questionnaires. Data sources came from public records, the results of questionnaire responses, and scientific articles related to SASAMBO traditional medicine. The results showed that there were various SASAMBO medicinal plants which were potentially used in the study of natural product chemistry with details, Lombok (Sasak) 43 species, Sumbawa (Samawa) 25 species, and Bima (Mbojo) 35 species. Some of these plant species are used for the treatment of diseases caused by viruses, so it has the potential to be used to treat corona outbreaks. Lombok and Sumbawa islands have abundant medicinal plants, this makes the two islands potential as a traditional health tourism destination.

Nowadays, the use of medicinal plants for disease treatment has been limited due to widely prevailing toxicity of medicinal plants and their source soil. The major reason for the toxicity in plants might be due to their mineral and chemical content and also related with the toxic materials present in the source soil. The aim of this study was to assess the Aluminum contamination in Mettur, an industrial town of Tamil Nadu, India which has many Al industries. Total Al content in the soil of the region where medicinal plants were cultivated was found to be 16700 mg kg-1. Further, Al content in commonly used medicinal plants Centella asiatica, Bacopa monneri and Euphorbia hirta grown in Al polluted soil was studied. The Al concentration of the medicinal plants ranged from 449 to 801 mg kg-1. All the three plants were found to accumulate level of Al which is above the maximum permissible limits prescribed by World Health Organization and thus, it may cause Al toxicity among the consumers of herbal medicines. From the results of the present study, it is inferred that the medicinal plants used for the human consumption or disease management should be collected from clean environment and processed carefully.
