Senna: As immunity boosting herb against Covid-19 and several other diseases.

Introduction: A novel coronavirus outbreak in China (SARS-CoV-2) which began in December 2019, was proven major threat to global health. However, several results from clinical practices indicate that herbal medicine plays an important role in the prevention of COVID-19, which brings new hope for its treatment. The objective of this study is to check the effectivity of senna (Senna alexandrina Mill.) as an immunity-boosting herb against Covid-19 and several other diseases. Method: The literature search was carried out using scientific databases comprising of Scopus, Science Direct, PubMed, Cochrane Library, Science Hub and Google Scholar, up to May 2020, using the following keywords: "senna", "senna makki", "Senna alexandrina", "senna nutrition value", "senna medicinal effect", "vitamins in senna", "mineral in senna", "bioactive compounds in senna", "laxiary components in senna", "senna against diseases", "senna enhance immunity", "covid_19″, "covid_19 symptoms". The authors also obtained data from primary and secondary sources as well. Result: The results of different studies showed that senna was composed of a wide range of immunity-enhancing bioactive components like antioxidants, vitamins, minerals and laxatives. These bioactive components are effective against COVID-19 and other diseases. Conclusion: Senna has medicinal and nutritional effects on the human body and has a key role in boosting immunity to prevent COVID-19 symptoms. Important nutritional components of senna include antioxidants, phytochemicals, vitamins and minerals that aids in reducing the risk of various diseases and also enhances the immune system.

Functional constituents of plant-based foods boost immunity against acute and chronic disorders.

Plant-based foods are becoming an increasingly frequent topic of discussion, both scientific and social, due to the dissemination of information and exchange of experiences in the media. Plant-based diets are considered beneficial for human health due to the supply of many valuable nutrients, including health-promoting compounds. Replacing meat-based foods with plant-based products will provide many valuable compounds, including antioxidants, phenolic compounds, fibers, vitamins, minerals, and some ω3 fatty acids. Due to their high nutritional and functional composition, plant-based foods are beneficial in acute and chronic diseases. This article attempts to review the literature to present the most important data on nutrients of plant-based foods that can then help in the prevention of many diseases, such as different infections, such as coronavirus disease, pneumonia, common cold and flu, asthma, and bacterial diseases, such as bronchitis. A properly structured plant-based diet not only provides the necessary nutrients but also can help in the prevention of many diseases.

Fiber-enriched botanicals: A therapeutic tool against certain metabolic ailments.

Plant-based foods are natural sources including vegetables, fruits, cereals and legumes. These foods consist of various types of nutrients in which carbohydrate is the basic component. However, some plant-based diets contain carbohydrates in the form of fiber. The fiber is usually a nondigestible polysaccharide that is not digested in the human body. It is present in the form of soluble or insoluble in different part of foods like peel, bran, pulp and grain. Pectin, beta-glucan, mucilage, psyllium, resistant starch and inulin are soluble fiber, and cellulose, hemicellulose and lignin are insoluble fiber attained from plant foods. The major function enhances immunity by creating gastrointestinal barrier, mucus production, immune cell activity and IgA level. Previous evidences showed that peoples with strong immunity have fewer chances of viral disease. A recent viral disease named COVID-19 spread in the world and millions of peoples died due to this viral disease. Coronavirus mostly attacks humans that suffer with weak immune system. It is due chronic diseases like diabetes and CVD (cardiovascular disease). The current review shows that fiber-containing plant-based foods boost immunity and aid human against COVID-19. The therapeutic role of fiber in the human body is to control the risk of hypertension and diabetes because a high-fiber diet has the ability to lower cholesterol, blood pressure and blood sugar. Fibers aid in GIT (gastrointestinal tract) and prevent constipation because it absorbs water and adds bulk to stool.

Coronavirus disease (COVID-19) and immunity booster green foods: A mini review.

This review focused on the use of plant-based foods for enhancing the immunity of all aged groups against COVID-19. In humans, coronaviruses are included in the spectrum of viruses that cause the common cold and, recently, severe acute respiratory syndrome (SARS). Emerging infectious diseases, such as SARS present a major threat to public health. The novel coronavirus has spread rapidly to multiple countries and has been declared a pandemic by the World Health Organization. COVID-19 is usually caused a virus to which most probably the people with low immunity response are being affected. Plant-based foods increased the intestinal beneficial bacteria which are helpful and make up of 85% of the immune system. By the use of plenty of water, minerals like magnesium and Zinc, micronutrients, herbs, food rich in vitamins C, D and E, and better life style one can promote the health and can overcome this infection. Various studies investigated that a powerful antioxidant glutathione and a bioflavonoid quercetin may prevent various infections including COVID-19. In conclusion, the plant-based foods play a vital role to enhance the immunity of people to control of COVID-19.
