ABSTRACT
The proteinaceous food value of mushrooms is well recognized and it may offer effective and lasting solutions to the problems of child malnutrition and protein supplement in pregnant ladies. Advancements have been made toward understanding mushroom biology, cultivation aspects, using a variety of agro lingo-cellulosic waste, breeding high yielding varieties, medicinal implications and uses of these unique fruiting bodies in bioremediation and waste water management. Mushrooms contain antioxidants and anticancerous chemicals in significant quanti-ties. Use of Chaga mushroom in corona virus disease control has been suggested recently in Russia. After first cultivation of rat ear fungus (Auricularia auricula) in 600 A.D., now more than 20 species are commercially cultivated and protocols to culture about 300 mushrooms is now known. New cultivation methods are devel-oped and discussed for Shiitake mushroom (Lentinula edodes), Lenzites sterioides, Reishi mushroom (Ganoderma lucidum) and Turkey tail (Trametes versicolor). The biological efficiency was 45% for Lentinus and 56% for Reishi in experi-ments conducted at Botany Department of the M.S. University of Baroda. An increase in yield was recorded when Lentinus mycelium was exposed to blue light and 5-10 ppm Veradix (IBA). The cultivation of medicinal mushroom is profitable as well fascinating since it requires a range of specific environmental conditions such as humidity, temperature, etc. The efforts have been made to eliminate the use of polythene bags by using earthen pots in case of oyster mushroom. A range of substrates have been used to increase the yield and manage agro-waste produced in large quantity in different countries. Cellulose and hemicellulose served as better sources of mushroom production, whereas, in lignin containing substrates the growth was slower. Apart from using substrates, dilute acid soaking of the leaves produced better growth of oyster. Light and temperature levels are also critical for the temperature required was 30 °C. Exposure to light acts as a shock to switch over the mycelium from vegetative to reproductive stage. The efforts are being made to increase number of fruiting bodies by the use of Ni and Sn salts. This chapter deals with spawn production and the advances in cultivation of four medicinal mushrooms made in different parts of the world. Mushrooms breeding and strain improvement has resulted into many new and high yielding strains. Production of oyster mushroom is done in almost all parts of the country, extensive fungal surveys are needed for developing better conservation strategies. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.
ABSTRACT
Aloe vera (L.) Burm.f. is nicknamed the 'Miracle plant' or sometimes as the 'Wonder plant'. It is a plant that has been used since ancient times for the innumerable health benefits associated with it. It is one of the important plants that has its use in conventional medicinal treatments. It is a perennial succulent, drought-tolerant member of the family Asphodelaceae. There are scores of properties associated with the plant that help in curing various forms of human ailments. Extracts and gels obtained from plants have been shown to be wonderful healers of different conditions, mainly various skin problems. Also, this plant is popular in the cosmetics industry. The underlying properties of the plant are now mainly associated with the natural phytochemicals present in the plant. Diverse groups of phytoingredients are found in the plant, including various phenolics, amino acids, sugars, vitamins, and different other organic compounds, too. One of the primary ingredients found in the plant is the aloin molecule. It is an anthraquinone derivative and exists as an isomer of Aloin A and Aloin B. Barbaloin belonging to the first group is a glucoside of the aloe-emodin anthrone molecule. Various types of pharmacological properties exhibited by the plant can be attributed to this chemical. Few significant ones are antioxidant, anti-inflammatory, anti-diabetic, anti-cancer, anti-microbial, and anti-viral, along with their different immunity-boosting actions. Recently, molecular coupling studies have also found the role of these molecules as a potential cure against the ongoing COVID-19 disease. This study comprehensively focuses on the numerous pharmacological actions of the primary compound barbaloin obtained from the Aloe vera plant along with the mechanism of action and the potent application of these natural molecules under various conditions.

Andean grains are key elements in the construction of family production systems. These seeds speak of the history of a people, their customs and ancestral knowledge. The general objective of the work was to evaluate the food use, crop management and traditional knowledge about the medicinal use of ancestral Andean grains among the inhabitants of the districts of Quinua and Acos Vinchos (Ayacucho-Peru). Basic descriptive research, carried out by means of convenience sampling, the sample size determined by the Law of Diminishing Returns, after signing an informed consent form. Semi-structured individual interviews were applied to 96 informants. A total of 96.9% of the informants reported that they obtained quinoa grain from their own crops, and 24.0% obtained achita grain that they sowed directly on their land;no cañihua was cultivated. A total of 58.3% use quinoa and achita in their diet. The variability of the food use of ancestral grains, specifically quinoa and achita, constitute a natural source of vegetable protein of high nutritional value, which represents one of the main foods of the inhabitants of Quinua and Acos Vinchos. Traditional medicine derived from the ancestral knowledge of Andean grains is barely preserved, but this is not the case for other medicinal plants in the area, as this knowledge is still preserved.
ABSTRACT
Indonesia's mindset has been focusing on the use of natural medicines, food, and healing practices widely recognized by the nation's culture. Traditional medicines and herbs used in traditional medicine can often lead to the discovery of drugs against certain diseases. The aim of this review was to study evidence-based data on the importance of Sembung plant, Blumea balsamifera, as a potential traditional medicine. The distribution, ethnopharmacology, secondary metabolites, and bioactivity against several diseases are focused in this review. Information and research related to Sembung plant were searched using the terms "B. balsamifera," "phytochemicals," and "pharmacological activity" on ResearchGate, Google Scholar, Science Direct, PubMed, and scientific information-based databases up to 2020. Several ethnomedical articles recommend B. balsamifera for the treatment of sinusitis, colic pain, cough, kidney stones, flu, or as a diuretic. This knowledge has already been applied in several countries in Southeast Asia. B. balsamifera has been reported to contain several phytochemicals both volatile (terpenoids, fatty acids, phenols, alcohol, aldehydes, ethers, ketones, pyridines, furans, and alkanes) and non-volatile (flavonoids, flavanones, and chalcones). Extracts and phytochemicals of B. balsamifera contain several biological capacities such as antioxidant, antimicrobial, antifungal, anti-inflammatory, hypolipidemic, anti-infertility, hepatoprotective activity, antidiabetic, gastroprotective, antitumor, anticancer, and immunomodulatory agent against Coronavirus disease-19 infection. This review provides essential data for the potential application of B. balsamifera as a nutraceutical or in future medicinal preparations.
