“…The nutritional value of any food substance can be analyzed by its proximate and mineral composition [24]. Literature-based screening of the proximate composition of D. esculentum revealed the presence of lipids, proteins, carbohydrates, vitamins, fiber, etc., while mineral composition possesses the presence of essential micro and macro compounds [25][26][27][28][29][30][31][32][33][34][35]. The comparative analyses of proximate and mineral composition of D. esculentum are presented in Tables 2 and 3.…”

The genus Diplazium (family: Athyriaceae) comprises approximately 350 species of pteridophytes. Diplazium esculentum (Retz.) Sw. is an important member of this genus and commonly known as a wild vegetable in the Himalayan and sub-Himalayan communities. According to the literature analysis, D. esculentum was traditionally used for the prevention or treatment of several diseases such as diabetes, smallpox, asthma, diarrhea, rheumatism, dysentery, headache, fever, wounds, pain, measles, hypertension, constipation, oligospermia, bone fracture, and glandular swellings. Various extracts of D. esculentum were evaluated to elucidate their phytochemical and pharmacological activities. A wide array of pharmacological properties such as antioxidant, antimicrobial, antidiabetic, immunomodulatory, CNS stimulant, and antianaphylactic activities have been recognized in different parts of D. esculentum. The review covers a systematic examination of pharmacognosy, phytochemistry, and pharmacological applications of D. esculentum, but scientifically, it is not fully assessed regarding complete therapeutic effects, toxicity, and safety in the human body. The published literature on D. esculentum and its therapeutic properties were collected from different search engines including Wiley online, PubMed, Springer Link, Scopus, Science Direct, Web of Science, Google Scholar, and ACS publications by using specific terms such as “Diplazium esculentum, bioactive compounds, biological activities and health benefits” from 1984 to 2021 (March). Therefore, further studies are required to identify the detailed action mechanism of D. esculentum in vitro/in vivo, and also, more studies should focus on conservation, cultivation, and sustainable utilization of the species.

“…These pteridophytes are harvested from wild without any consideration of their sustainable use thus overharvesting is creating challenges for conservation. The edible ferns can also help to overcome nutritional deficiency especially in hilly areas (Chettri et al 2018).…”

Background: Traditional use of pteridophytes as food and medicine is a common practice around the world. Many ethnic communities hold vast knowledge about the uses of pteridophytes and the documentation of such knowledge and biodiversity of edible and medicinal pteridophytes is important for health care, food security and conservation. Although being one of the biodiversity rich countries, the detailed use of edible and medicinal pteridophytes from Nepal is not well documented and they are one of the underutilized plant resources having vast potential. Thus, the aim of this review is to compile the knowledge about the use of edible and medicinal pteridophytes in Nepal.Methods: Relevant information on traditional uses as medicinal and edible species were collected form published literatures such as research articles on ethnobotanical surveys, books, book chapters and conference proceedings.Results: The literature survey revealed that a total of 26 species of pteridophytes were used as food and 43 species were used as traditional medicines. Among 55 useful species, 14 species were used as both food and traditional medicine. Diplazium esculentum, Diplazium maximum, Dryopteris cochleata and Ophioglossum reticulatum were common edible species and Aleuritopteris albomarginata, Equisetum ramosissimum, Nephrolepis cordifolia and Tectaria coadunata were common medicinal pteridophytes. Most of species are growing in natural habitat and the potential utilization species were sold in the market which has also supported livelihood. Some of these pteridophytes were also used in preparation of ethnic foods such as fermented foods and pickles. Conclusion:Findings from the study suggested that only a few common species of pteridophytes are used as food and traditional medicines Nepal. The knowledge about the traditional uses of pteridophytes and their biodiversity is also affected by socioeconomic changes in communities, lack of sharing of traditional knowledge through generations, improper collection practices and climate change. Very few pteridophytes from Nepal have been studied in detail for their phytoconstituents and biological activities and safety. Future research activities should focus on providing scientific evidence for traditional uses as well as development of proper conservation, cultivation, and product formulation methods in a sustainable manner.

“…Wild vegetables are uncultivated but edible plants and distributed around the world. By supplying the body with protein, minerals, vitamins, and certain hormone precursors, wild vegetables play an important role in the human daily diet, especially in some developing countries such as China, Russia, and Thailand ( 5 ). Also, some of them provide important health benefits because of their nutritional and pharmacological characteristics ( 6 ).…”

BackgroundHeavy metal(loid)s are frequently detected in vegetables posing potential human health risks, especially for those grown around mining areas. However, the oral bioaccessibility and gingival cytotoxicity of heavy metals in wild vegetables remain unclear.MethodsIn this study, we assessed the total and bioaccessible Cr, As, Cd, Pb, and Ni in four wild vegetables from mining areas in Southwest China. In addition, the cytotoxicity and underlying mechanisms of vegetable saliva extracts on human gingival epithelial cells (HGEC) were studied.ResultsThe Plantago asiatica L. (PAL) showed the highest bioaccessible Cr, As, Cd, and Pb, while the greatest bioaccessible Ni was in Taraxacum mongolicum (TMM). The Pteridium aquilinum (PAM), Chenopodium album L. (CAL), and TMM extracts decreased cell viability, induced apoptosis, caused DNA damage, and disrupted associated gene expressions. However, PAL extracts which have the highest bioaccessible heavy metals did not present adverse effects on HGEC, which may be due to its inhibition of apoptosis by upregulating p53 and Bcl-2.ConclusionOur results indicated that polluted vegetable intake caused toxic effects on human gingiva. The heavy metals in vegetables were not positively related to human health risks. Collectively, both bioaccessibility and toxic data should be considered for accurate risk assessment.
