The fluminense vegetation, more specifically the flora from the Jurubatiba restinga has been investigated by a multidisciplinary team of botanists, chemist, radiobiologist, insect physiologists and geneticist. Vouchers of 564 specimens have been collected, identified, organized in an herbarium, and a database is being build up containing, in addition to classical botanical data, chemical data and information on the potential economic use either for landscape gardening, alternative foods or as medicinal plants. Phytochemical studies of the Guttiferae, Clusia hilariana, yielded oleanolic acid and nemorosone. Their biological activities against the haematophagous insect Rhodnius prolixus vector of Chagas disease have been investigated. Finally, it has been observed that aquatic plants possessed high levels of the natural radionuclide polonium-210, which seems to be originated mainly from soil rather than from atmospheric supply.

The roots of Iostephane heterophylla are popular in Mexican traditional medicine and as such are a good candidate to develop herbal drug preparations to be used as phytomedicine. International criteria for validation and standardization of a herbal product as phytomedicine include, among others, the integration of microscopic and histochemical characteristics of the raw material, as in this case the herbal drug, to guarantee its authenticity. As an original contribution to the knowledge of the root structure of this species, fresh roots fixed in FAA, were processed with conventional histological techniques (paraffin embedment and subsequent transversal and longitudinal sections that were stained with safranin-fast green) and stained with histochemical markers for identification of cellular contents. The root description includes dermic, fundamental and vascular tissues as well as cellular contents (proteins, polysaccharides, polyphenols, condensed and hydrolyzed tannins, starches and lipids, some of which have been isolated in previous phytochemical studies). These characteristics are compared to those of other species of Asteraceae as an initial comparative study to contribute to identify medicinal plants based upon their underground parts.

Iran is an ancient country in the usage of medicinal plants and Ahar is known as one of the richest regions of medicinal plants. The traditional knowledge about medicinal plants is the basic step in many drug productions and these kinds of information should be documented through botanical investigations. The present study is the first survey conducted in this region and its primary point is to distinguish such plants and to present their application in traditional medicine. In this study, the data was gathered by talking with indigenous individuals to identify medicinal plants with local importance developed during the 2015 and 2016 growing seasons. Scientific names and therapeutic uses are also mentioned. The results obtained from the present study indicated that there were 46 medicinal species of 23 families in Ahar and local people mainly used Lamiaceae and Asteraceae then Rosaceae, Brassicaceae, Fabaceae, and Zygophyllaceae medicinal taxa. Medicinal plants were mostly used to treat intestinal-digestive disorders, for cold treatment and for soothing pain. According to results, significant ethnobotanical data on medicinal plants gives premise information to future pharmacological and phytochemical studies. Also, this document can be utilized as a part of protecting indigenous knowledge.

Symptoms And Signs

The ethnobotanical study carried out at Madingou (4°16' S, 13°33' E) focuses on medicinal plants of the savannah zone. The survey used personal interviews and focus groups. Informants consisted of the inhabitants, whose age varies from 18 to 60 years or more. A total of 80 plant species were cited in the traditional pharmacopoeia. These plants are used in 66 recipes for treating 43 different diseases and symptoms, grouped in 11 major affiliations following the disease and symptoms sphere. Infectious and parasitic diseases is the most important group (23.25%), followed by the ill-defined symptoms and signs (13.95%) and the digestive system (11.63%). Five modes of administration were noted. The most preferred being the oral voice (38.75%). Among the 7 types of plant parts cited, leaves (65%) are preponderant. 8 modes of preparation were cited, the decoction (23.75%) being the most common. Of the 80 species listed, Allium sativum, Persea americana, Solanum nigrum, are among the medicinal plants most commonly used in Africa. Of the remaining species, 9 have been the subject of phytochemical studies all over the world. Ethnobotanical data show that a number of taxa, the medicinal properties of which are proved elsewhere, exist in the region and are not exploited, such as Millettia laurentii. Several species inventoried cover more than one aspect of indigenous knowledge, they are referred to as multipurpose plants and therefore the most vulnerable of the anthropic influences.

Background: Resistance of malaria parasites to existing drugs complicates treatment, but an antimalarial vaccine that could protect against this disease is not yet available. It is therefore necessary to find new effective and affordable medicines. Medicinal plants could be a potential source of antimalarial agents. Some medicinal plants from Burkina Faso were evaluated for their antiplasmodial and cytotoxic properties in vitro.Methods: Crude dichloromethane, methanol, water-methanol, aqueous and alkaloids extracts were prepared for 12 parts of 10 plants. Chloroquine-resistant malaria strain K1 was used for the in vitro sensibility assay. The Plasmodium lactacte dehydrogenase technique was used to determine the 50% inhibitory concentration of parasites activity (IC50). The cytotoxic effects were determined with HepG2 cells, using the tetrazolium-based colorimetric technique, and the selectivity index (SI) was calculated.Results: Sixty crude extracts were prepared. Seven extracts from Terminalia avicenoides showed IC50 < 5 µg/mL. The IC50 of dichloromethane, methanol, aqueous and alkaloids extracts ranged between 1.6 µg/mL and 4.5 µg/mL. Three crude extracts from Combretum collinum and three from Ficus capraefolia had an IC50 ranging between 0.2 µg/mL and 2.5 µg/mL. Crude extracts from these three plants had no cytotoxic effect, with SI > 1. The other plants have mostly moderate or no antimalarial effects. Some extracts from Cordia myxa, Ficus capraefolia and Opilia celtidifolia showed cytotoxicity, with an SI ranging between 0.4 and 0.9.Conclusion: Our study showed a good antiplasmodial in vitro activity of Terminalia avicenoides, Combretum collinum and Ficus capraefolia. These three plants may contain antiplasmodial molecules that could be isolated by bio-guided phytochemical studies.

Background: The COVID-19 pandemic is causing many severe problems globally, and it is not known for how long it will last. The only hope we have for dealing with the problem is to produce sufficient vaccines and administer them efficiently. However, the current demand for vaccines greatly exceeds the supply, and many people will suffer from the disease for still some time. Moreover, the period for immunity obtained by the vaccines remains unknown, and we cannot predict how long the world will suffer the COVID-19 infections. Therefore, there will be a continued demand for treatments of its symptoms. An alternative solution for providing such treatment is the use of traditional medicinal plants.Aims: To document medicinal plants used by Hmong and Karen in Thailand to treat mild symptoms of COVID-19.Methods: Traditional knowledge about ethnomedicinal plants used by Hmong and Karen in Thailand for treating mild symptoms listed by WHO as associated with COVID 19, was collected in field interviews and extracted from the literature.Results: We identified 491 plant species used medicinally by both ethnic groups to treat fever, cough, diarrhea, muscle pain and ache, rash, headache, sore throat, and conjunctivitis. Of the 491 species 60 were mentioned at least five times in the literature or in our field data. Of these 60 species, we propose the most commonly used ones for treatments of mild COVID-19 symptoms. Ten of these most commonly mentioned species were used for treatments of fever, nine for treatment of cough, four for treatment of diarrhea, two for treatment of rash, and a single species was used to treat muscle pain and headache.Conclusion: This study suggests alternative treatments for mild symptoms of COVID-19 with medicinal plants that are traditionally used by the ethnic minority groups of the Hmong and Karen in Thailand. Although COVID-19 is a new disease, its mild symptoms are shared with many other diseases. Traditional knowledge on medicinal plants used by the Thai Karen and Hmong could help in the treatments of these symptoms associated with COVID-19. Many of the proposed plants were used abundantly by both ethnic groups, and other studies on biological activities support their efficacy in such treatments.
