‘Gandho badali’ (Paederia foetida L.), a well-known medicinal plant from the family Rubiaceae with a fetid smell, is indigenous to Bangladesh, but also native to several other South- and Far-Eastern Asian countries like Bhutan, Cambodia, China, India, Indonesia, Japan, Laos, Malaysia, Nepal, South Korea, Taiwan and Vietnam. In addition to the Bengali name ‘Gandho badali’, this perennial climber is also commonly known as ‘Gandhobadulia’, ‘Kings tonic’, ‘Skunkvine’, ‘Stinkvine’ an ‘Chinese fever vine’. Phytochemical investigations on this plant established the presence of alkaloids, anthraquinones, coumarins, iridoids, lignans, phenolics, steroids and terpenoids. Aizarin, asperuloside, campesterol, 1,3-dihydroxy-2-methoxyanthraquinone, digiferrol, ellagic acid, epifriedelinol, friedelin, lupeol, morindaparvin A, paederoside, paederosidic acid, sitosterol, stigmasterol and ursolic acid are the major secondary metabolites found in various parts of P. foetida.

Herbal medicines are widely used as alternative treatments for various chronic diseases. They have proved to be of immense importance in treating many diseases and conditions. These medicines have potential to decrease the side effects of other drugs. In this regard Betel vine (Piper betel) leaves are known for its medicinal properties since long. It is a cash crop for many under developed Southeast Asian countries and therefore also known as “Green Gold and Green Heart" in those countries, as many people cultivate this crop to meet their both ends. The contemporary world approves its several medicinal properties as the growth of knowledge in this regard is unprecedented. The objective here is to reveal the potential effect of this plant against different diseases. Along with its tradomedicinal uses which signify its tremendous potential, it is also used towards cure of many antimicrobial ailments of great concern. The leaf extract and purified compounds are found to play a vital role and are of immense benefits in oral hygiene, anti-diabetic, cardiovascular, anti-inflammatory, and anti-ulcer. The active compounds isolated from leaf and other parts have great therapeutic role. This paper basically focus  on  emphasizing  the  varied pharmacological  properties  of  Piper  betel  Linn along with its traditional uses and a cursory view of its active constituents.

Euclea divinorum Hern (Ebenaceae) has a long history of folkloric use in the treatment of different diseases. However, there are few reports on the responsible phytochemicals in its tender stems, leaves and root bark. The aim of this study was to compare the phytochemicals in E. divinorum leaves, tender stems and root bark. The plant materials were extracted serially by maceration with dichloromethane, hexane and ethanol. Alkaloids, phenols, saponins, flavonoids, steroids, cardiac glycosides, tannins, terpenes, and volatile oils were identified in qualitive Phytochemical screening of the extracts. UV Visible and Fourier Transform infrared spectroscopy indicated the presence of alcohols, phenols, alkanes, alkenes, alkynes, aldehydes, carboxylic acids, aromatics, nitro compounds and amines in the extracts. Gas chromatography/mass spectrometry afforded identification and quantification of 30 compounds in the hexane and dichloromethane extracts. The major constituents were3,4-Methylenedioxybenzylacetone, Eicosane, Tetratriacontane, Hexatriacontane, 9-Hexadecen-1-ol, 2-Hydroxy-2-methyl-8,8-diphenyl-octa-5,7-dien-3-one, 1,4-Naphthoquinone and Octacosanal. The compounds identified in the different extracts of Euclea divinorum leaves, tender stems and root bark supports the use of this plant in traditional medicine.

Poisonous snake envenomation is a complex neglected health problem implicated in mortality, disability, psychological morbidity, and socio-economic losses recorded worldwide. An antivenin serum, the only medically recommended treatment for snakebites, has several drawbacks including, hypersensitivity, inability to prevent local tissue damage, are scarce and unaffordable in most snakebite endemic areas. In many rural communities all over the world, plants have been utilized for managing snakebites. This review seeks to identify plants reported as antivenom remedies in the East Africa and the scientific studies thereof which could support their use in the treatment of snake envenomation. A review of scientific articles was undertaken to identify information on traditional knowledge of medicinal plants used to treat snake envenomation in East Africa and their antivenom efficacy. A total of 361 plant species were retrieved to have been reported as traditional therapies for snakebites in East Africa. The review identified distinct cases of doctrine of signatures and zoopharmacognosy in snakes using Opilia amentacea, Hugonia castaneifolia and Microglossa pyrifolia respectively. Evaluations of the antivenom efficacy of 44 species (12.2%) have been done globally, and most species found to be effective in neutralizing the lethal activities of snake venoms. Ethnomedicinal plants play a revered holistic role in East African antisnake venom therapy. Conyza sumatrensis, Hyptis pectinata, Justicia betonica, and Maesa lanceolata used to treat specific snakebites merit further studies.

Coronavirus is one of the main pathogens that targets the human respiratory system in the first place and since common treatments for coronavirus, including hydroxychloroquine are mostly symptomatic, so the aim of this study was to evaluate the coronavirus and salt intake. Articles in Medline searched using the keywords Respiratory infection and Coronavirus, COVID-19 and salt. The virus is highly contagious, dangerous and poses a great threat to the health and safety of the world, and its spread must prevented immediately. The corona pandemic seems to be able to build a new lifestyle. This can be a starting point for changing the eating behaviors of East Asians and even the people of the world. On the other hand, in addition to the new approach to the role of nutrition in etiology and treatment of diseases in traditional medicine, salt is one of the essential substances for the body that used in the treatment of more than 40 diseases, including treatment of infection and prevents infection in the blood. The findings suggest that increasing the pH plays an important role in the therapeutic performance of drugs used in modern medicine in the treatment of Coronavirus, which salt also creates a similar mechanism. It targets the gastrointestinal tract and muscles and undersexed people at risk. It can conclude that salt that has a temperature of 4 degrees can probably be effective in reducing cold nature of the lungs and other organs.

The results of the phytochemical analysis of a Hypericum richeri Vill. accession collected from a population living in Appennines, Central Italy, are reported in this paper. The secondary metabolites pattern resulted mainly composed of flavonoids as both aglycones and in glycosidic form, such as quercetin (2), quercetin-3-O-methyl ether (3), 5,7,3′,5′-tetrahydroxyflavanone (8), isorhamnetin glucoside (7), isoquercitrin (9), hyperoside (10), quercitrin (11) and myricetin-3-O-rutinoside (12). It was also observed the presence of the naphtodianthrones hypericin (5) and pseudohypericin (6) together with organic acids (benzoic acid (4)), a glycolipid (2S)-1,2-di-O-[(9Z,12Z,15Z)-octadeca9,12,15-trienoyl]-3-O-β-D-galactopyranosyl glycerol (1) and the saccharides glucose (13), galactose (14) and sucrose (15). Among these constituents, compounds (1) and (3) have been identified in H. richeri Vill. for the first time during this study. The other difference in composition observed in the present study in respect to population from different regions is the absence of hyperforin and caffeoylquinic derivatives. The observed chemovariability, already reported in H. perforatum L., might be derived from the environmental characteristic of the collection site. The chemotaxonomic aspects, together with the pharmacologic relevance in traditional medicine of the isolated compounds were also discussed.
