Nigella sativa, anthemis hyaline and natural honey are promising for COVID-19 treatment
Background:
A new type of coronavirus, novel coronavirus (COVID-19), is causing an increasing number of cases of pneumonia and was declared a Public Health Emergency of International Concern by the World Health Organization on 30 January 2020. The virus first appeared in Wuhan, China, in late December 2019, and traditional Chinese herbal medicine is being used for its treatment. This systematic review and meta-analysis will assess studies of the effects of traditional Chinese herbal medicine in COVID-19 pneumonia.
Methods:
We will search electronic databases including PubMed, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), Chinese Science and Technology Periodical Database (VIP), and Wanfang database using keywords related to COVID-19 and traditional Chinese herbal medicine. Reference lists of relevant trials and reviews will be searched. We will manually search gray literature, such as conference proceedings and academic degree dissertations, and trial registries. Two independent reviewers will screen studies (XL and DZ), extract data (YL and LG), and evaluate risk of bias (YL and DZ). Data analysis will be conducted using the Review Manager software (version 5.3.5) and R software (version 3.6.1). Statistical heterogeneity will be assessed using a standard chi-square test with a significance level of P < 0.10. Biases associated with study size (e.g., publication bias) will be investigated using funnel plots, Egger's test and Begg's test, and Trim and Fill analysis.
Discussion:
This study will provide a high-quality synthesis of the effects of traditional Chinese herbal medicine for COVID-19. The use of traditional Chinese herbal medicine for treatment or prevention of these novel viral infections affecting the pneumonia will be investigated.

This study is conducted to evaluate the therapeutic and antioxidant effect of lemon juice on some hematological and biochemical parameters. Thirty female mice used in this study were exposed to oxidative stress through giving them hydrogen peroxide in drinking water for 30 days. Animals randomly distributed over 3 groups, each group contained 10 animals and treated as follows: T1 control group (drinking distilled water only), T2 (0.75% hydrogen peroxide in drinking water) and T3 (0.75% hydrogen peroxide in drinking water with daily drenching with 1 mL lemon juice). At the end of the experiment, blood samples were collected from animals for evaluating the following hematological and biochemical parameters: Haemoglobin concentration (Hb), red blood cells count (RBC), white blood cells count (WBC), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), platelet count (PLT), level of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and total protein. The results showed that T3 exhibited an enhancement in RBC count, Hb concentration, WBC, lymphocyte and total protein and reduction in the level of AST and ALT compared to T2. These findings clearly revealed the advance protective and antioxidant features of lemon juice on hematological and biochemical parameters of the oxidatively stressed female mice.
Phenolic profiling of ten plant samples of Mentha rotundifolia (L.) Huds. collected from different bioclimatic areas of Tunisia, was for the first time carried out by using a fast ultra-high-performance liquid chromatography (UHPLC)-high resolution tandem mass spectrometry (HRMS/MS) method on a Q Exactive platform equipped with an electrospray ionization (ESI) source. An intraspecific, interpopulation variability was evidenced and a total of 17 polyphenolic metabolites were identified and quantified by using the UHPLC-HRESIMS/MS method, here validated for specificity, linearity, limit of detection, limit of quantitation, accuracy and precision. The quantitative method resulted sensitive at the nM level and reliable for rapid polyphenol quantification in vegetal matrices. The metabolomic study allowed us to identify a new compound, named salvianolic acid W, which was isolated and characterized mainly by NMR and MS analysis. A statistical correlation of the phenolic composition with antioxidant and anti-acetylcholinesterase activities was provided.
Human societies have been in close contact with their environments since the beginning of their formation and used the ingredients of the environment to obtain food and medicine. Awareness and application of plants to prepare food and medicine have been realized through trial and error, and gradually human became able to meet his needs from his surroundings. Information about medicinal plants has long been transmitted gradually and from generation to generation, a human knowledge has gradually become complete with the formation of civilizations and the provision of more facilities. Medicinal plants are used as a medical resource in almost all cultures. Ensuring the safety, quality and effectiveness of medicinal plants and herbal drugs very recently became a key issue in industrialized and developing countries. By standardizing and evaluating the health of active plant-derived compounds, herbal drugs can help the emergence of a new era of the healthcare system to treat human diseases in the future. Awareness of traditional knowledge and medicinal plants can play a key role in the exploitation and discovery of natural plant resources. In order to maintain this knowledge, comprehensive approach and collaboration are needed to maintain historical records on medicinal plants and use these resources in favour of human beings, before they are destroyed forever. Therefore, this review was conducted to investigate and describe the process of using medicinal plants throughout history. This review focuses on the recent various important challenges in quality evaluation of medicinal plants in the authenticity, efficacy, toxicity and consistency.

Zizyphus lotus , belonging to the Rhamnaceae family, is a deciduous shrub which generally grows in arid and semiarid regions of the globe. In traditional medicine, Z. lotus is used as antidiabetes, sedative, bronchitis, and antidiarrhea by local populations. Recently, several scientific reports for health benefit and nutritional potential of bioactive compounds from this jujube have been reported. This plant is rich in polyphenols, cyclopeptide alkaloids, dammarane saponins, vitamins, minerals, amino acids, and polyunsaturated fatty acids. These identified compounds were supposed to be responsible for most of Z. lotus biologically relevant activities including antimicrobial, anti-inflammatory, hypoglycemic, antioxidant, and immunomodulatory effects. The aim of the present review was to give particular emphasis on the most recent findings on biological effects of the major groups of Zizyphus lotus components and their medical interest, notably for human nutrition, health benefit, and therapeutic impacts.
Background
Limited evidence supports Nigella sativa?s role as an effective complementary and alternative medicine and the anti-inflammatory effects of Nigella sativa on patients with allergic rhinitis.
Objective
The aim of this study was to investigate the effect of topical application of Nigella sativa oil and oral acetaminophen on pain in the elderly with knee osteoarthritis residing in a parents? home in Sabzevar.
Methods
This study is done as a crossover clinical trial. After obtaining written consent of elderly patients with osteoarthritis of the knee, they were randomly divided into two groups. In step 1, in group 1, 1 cc of Nigella sativa oil was applied on the knee joint every 8 hours for 3 weeks; for the second group, every 8 hours for 3 weeks, patients were given 1 tablet of 325 mg acetaminophen. After a period of 1 month without medication to wash out each group, in step 2, each treatment group received the drug interaction in the same way as above. Pain was determined using a visual scale (VAS) before and after the first and second stages. Treatment response was defined as a decrease in pain scores over 1.5. Data analysis was performed with an R software mixed model.
Results
This study was done on 40 elderly patients: 18 (45%) men and 22 (55%) women. Their mean year and weight were 75.66?8.9 years and 69.67?14.33 kg, respectively. Study results showed that topical application of Nigella sativa oil and oral acetaminophen reduced pain in elderly with knee osteoarthritis; after using Nigella sativa oil, the reduction of pain was higher (p=0.01).
Conclusion
The results of this study showed that topical application of Nigella sativa oil was effective in reducing pain in patients with knee osteoarthritis; therefore, it is recommended as a safe supplement for these elderly.

The objective of this study is to investigate the association between osteoarthritis (OA) and all-cause mortality in worldwide populations and to develop recommendations according to GRADE evidence levels. Literature search through Nov 2015 was performed using the electronic databases (including MEDLINE, EMBASE, EBSCO and Cochrane library). The prospective cohort trials that investigated the association between the symptomatic OA (SxOA) or radiological OA (ROA) and all-cause mortality were identified. Hazard ratios (HR) of all-cause mortality in patients with RxOA or ROA were pooled respectively. The evidence quality was evaluated using the GRADE system, while the recommendations were taken according to the quality. Nine of the published literature met the eligible criteria. Meta-analysis revealed that there was no significant difference in the association between SxOA and all-cause mortality (HR = 0.91, 95% CI: 0.68–1.23) and between ROA and all-cause mortality (HR = 1.13, 95% CI: 0.95–1.35). The overall GARDE evidence quality was very low, which will lower our confidence in taking recommendations. To summarize, there was no reliable and confident evidence existed currently in respect of the association between OA and all-cause mortality. Due to the very low level of evidence quality currently, high-quality studies are still required.
Introduction: Herbs are rich sources of natural antioxidants, and are used in traditional medicine for the control and treatment of many diseases. The reducing effect of a large number of these plants on blood glucose has been approved in animal models and clinical studies.
Objectives: This study was therefore, performed to investigate the hypoglycemic effect of Salvia officinalis on blood glucose, Glycosylated hemoglobin (HbA1c), lipid profile, liver and kidney function tests.Patients and Methods: A double-blind clinical trial was carried out on 80 type II diabetic patients who had not reached the ideal control of the disease. Patients were randomly divided into two equal groups of case and control. The case group received Salvia officinalis and the control group received placebo tablets three times a day for three months. The fasting blood sugar (FBS) and 2 hours postprandial (2hpp) glucose were checked at the beginning and every 2 weeks, for three months Glycosylated hemoglobin (HbA1c), lipid profile, liver and kidney function tests were also measured at the beginning and at the end of trial and compared in two mentioned groups.
Results: The 2hpp blood sugar and cholesterol levels were significantly decreased in Salvia officinalis treated patients compared to control group (p<0.05). There were no significant changes in glycosylated hemoglobin and FBS between the two groups.
Conclusion: Results showed that Salvia officinalis might be beneficial in diabetic patients to reduce 2hpp and cholesterol. However higher doses might be needed to decrease fasting blood glucose and glycosylated hemoglobin.

The term of medicinal plants include a various types of plants used in herbalism with medicinal activities. These plants are considered as rich resources of ingredients which can be used as complementary and alternative medicines and, also in drug developments and synthesis. In addition, some plants regarded as valuable origin of nutrition. Thus, all these plants are recommended as therapeutic agents. Information related to medicinal plants and herbal drugs accumulated over the ages are scattered and unstructured which make it prudent to develop a curated database for medicinal plants. MPDB 1.0 database is dedicated to provide the first window to find the plants around Bangladesh claimed to have medicinal and/or nutritive values by accumulating data from the published literatures. This database contains 406 medicinal plants with their corresponding scientific, family and local names as well as utilized parts for treatment from different districts of Bangladesh. Information regarding ailments is available for 353 plants. In addition, we have found active compounds for 78 plants with their corresponding PubMed ID.

Treatment of diabetic subjects with cinnamon demonstrated an improvement in blood glucose concentrations and insulin sensitivity but the underlying mechanisms remained unclear. This work intends to elucidate the impact of cinnamon effects on the brain by using isolated astrocytes, and an obese and diabetic mouse model.
Cinnamon components (eugenol, cinnamaldehyde) were added to astrocytes and liver cells to measure insulin signaling and glycogen synthesis. Ob/ob mice were supplemented with extract from cinnamomum zeylanicum for 6 weeks and cortical brain activity, locomotion and energy expenditure were evaluated. Insulin action was determined in brain and liver tissues.
Treatment of primary astrocytes with eugenol promoted glycogen synthesis, whereas the effect of cinnamaldehyde was attenuated. In terms of brain function in vivo, cinnamon extract improved insulin sensitivity and brain activity in ob/ob mice, and the insulin-stimulated locomotor activity was improved. In addition, fasting blood glucose levels and glucose tolerance were greatly improved in ob/ob mice due to cinnamon extracts, while insulin secretion was unaltered. This corresponded with lower triglyceride and increased liver glycogen content and improved insulin action in liver tissues. In vitro, Fao cells exposed to cinnamon exhibited no change in insulin action.
Together, cinnamon extract improved insulin action in the brain as well as brain activity and locomotion. This specific effect may represent an important central feature of cinnamon in improving insulin action in the brain, and mediates metabolic alterations in the periphery to decrease liver fat and improve glucose homeostasis.
Alendronate belongs to a class of drugs called bisphosphonates. Bisphosphonates (BP) therapy is a vital option to reduce the risk of bone fracture in people who suffer from osteoporosis. Yet, bisphosphonate have displayed several side effects. Lepidium sativum (LS) seeds have been used in traditional folk medicine to heal fractured bones. However, there is a dearth of information on the impact of LS on bone metabolism especially in cases of glucocorticoids induced osteoporosis. Therefore, the aim of the study was to compare the biochemical bone markers and histological responses of LS alone (6 g of LS seeds in diet daily, n=8), ALD (alendronate, 70 mg/kg s.c.; n=8) alone, or LS and ALD combined in a rat model of glucocorticoid-induced osteoporosis (GIO) by injecting rats with methylprednisolone 3.5 mg/kg per day for 4 weeks. Serum calcium (Ca), albumin, phosphorus (P), bone-specific alkaline phosphatase (b-ALP), and tartrate-resistant acid phosphatase (TRAP) were measured 4 weeks after induction of GIO. GIO-group showed significantly increased serum TRAP and decreased b-ALP. GIO-group also showed significantly decreased serum P and unaltered Ca concentrations. Histological examination of GIO-group tibia bones indicated an osteoporotic change and a concomitant decrease in percentage of trabecular area or bone marrow area (PTB) in the proximal femoral epiphysis. Treatment with either LS and/or ALD ameliorated the above mentioned changes with variable degrees, with a net results of enhanced serum calcium, bone architecture, PTB, b-ALP and decreased TRAP in LS and LS+ALD groups compared to that of animals treated with alendronate alone. In conclusion, our findings present evidence supporting the potential benefits of LS in reducing the burden of GCs on bone health.
Lepidium sativum L. is a fast growing edible herb which belongs to family Brassicaceae. The seeds of L. sativum are aperient, diuretic, tonic, demulcent, carminative, galatogogue and emmenagogue. They have been used in the treatment of bacterial and fungal infections, as an aperient and also possess antibacterial and antifungal properties. The seeds of this plant possess rapid bone fracture healing ability. Despite of its diverse medicinal properties no molecular data for diversity analysis is available till date. During this study random amplified polymorphic DNA (RAPD) markers were used to detect genetic variations of L. sativum. Initially 50 decamer primers were screened, out of which only 32 primers showed reproducible fragments with easily recordable bands. A total of 414 reproducible and clear bands were distinguished across the selected primers and statistical analysis showed 361 polymorphic bands and 53 monomorphic bands. Cluster analysis of the genotypes based on UPGMA divided the 18 genotypes into two main clusters, with first cluster having only HCS-20 genotype of L. sativum and other having rest of all 17 genotypes. The dendrogram based on similarity matrix revealed 23–66% genetic relatedness among 18 genotypes. The results of the present study can be used for molecular breeding and improvement of L. sativum for various desired traits through hybridization in future.
The present study was conducted to investigate the effects of Nigella sativa and Lepidium sativum on the pharmacokinetics of cyclosporine in rabbits. Two groups of animals were treated separately with Nigella sativa (200 mg/kg p.o.) or Lepidium sativum (150 mg/kg p.o.) for eight consecutive days. On the 8th day, cyclosporine (30 mg/kg p.o.) was administered to each group one hour after herbal treatment. Blood samples were withdrawn at different time intervals (0.0, 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0, 12, and 24 hrs) from marginal ear vein. Cyclosporine was analyzed using UPLC/MS method. The coadministration of Nigella sativa significantly decreased the C max and AUC0-∞ of cyclosporine; the change was observed by 35.5% and 55.9%, respectively (P ≤ 0.05). Lepidium sativum did not produce any significant change in C max of cyclosporine, although its absorption was significantly delayed compared with control group. A remarkable change was observed in T max and AUC0-t of Lepidium sativum treated group. Our findings suggest that concurrent consumption of Nigella sativa and Lepidium sativum could alter the pharmacokinetics of cyclosporine at various levels.
Medical plants play an important role in the management of diabetes mellitus especially in developing countries where resources are meager. This review presents the profiles of plants with hypoglycaemic properties, reported in the literature from 1990 to 2000. The profiles presented include information about the scientific name, family, methodology used, the degree of hypoglycaemic activity and the active agents. The large number of plants described in this review (176 species belonging to 84 families) clearly demonstrated the importance of herbal plants in the treatment of diabetes. It also shows the effort to isolate new potential antidiabetic agents. The plant families, including the species (sp), most studied for their confirmed hypoglycaemic effects include: Leguminoseae (11 sp), Lamiaceae (7 sp), Liliaceae (8 sp), Cucurbitaceae (7 sp), Asteraceae (6 sp), Moraceae (6 sp), Rosaceae (6 sp), Euphorbiaceae (5 sp) and Araliaceae (5 sp). The most studied species are: Citrullus colocynthis (Opuntia streptacantha Lem. (Cactaceae), Trigonella foenum greacum L. (Leguminosea), Momordica charantia L. (Cucurbitaceae), Ficus bengalensis L. (Moraceae), Polygala senega L. (Polygalaceae), and Gymnema sylvestre R. (Asclepiadaceae). Many studies have confirmed the benefits of medicinal plants with hypoglycaemic effects in the management of diabetes mellitus. The effects of these plants may delay the development of diabetic complications and correct the metabolic abnormalities. Moreover, during the past few years some of the new bioactive drugs isolated from hypoglycaemic plants showed antidiabetic activity with more efficacy than oral hypoglycaemic agents used in clinical therapy.
The objective of this study was to determine whether cinnamon improves blood glucose, triglyceride, total cholesterol, HDL cholesterol, and LDL cholesterol levels in people with type 2 diabetes.
A total of 60 people with type 2 diabetes, 30 men and 30 women aged 52.2 +/- 6.32 years, were divided randomly into six groups. Groups 1, 2, and 3 consumed 1, 3, or 6 g of cinnamon daily, respectively, and groups 4, 5, and 6 were given placebo capsules corresponding to the number of capsules consumed for the three levels of cinnamon. The cinnamon was consumed for 40 days followed by a 20-day washout period.
After 40 days, all three levels of cinnamon reduced the mean fasting serum glucose (18-29%), triglyceride (23-30%), LDL cholesterol (7-27%), and total cholesterol (12-26%) levels; no significant changes were noted in the placebo groups. Changes in HDL cholesterol were not significant.
The results of this study demonstrate that intake of 1, 3, or 6 g of cinnamon per day reduces serum glucose, triglyceride, LDL cholesterol, and total cholesterol in people with type 2 diabetes and suggest that the inclusion of cinnamon in the diet of people with type 2 diabetes will reduce risk factors associated with diabetes and cardiovascular diseases.
The novel Coronavirus disease 2019 (COVID-19) is caused by SARS-CoV-2, which is the causative agent of a potentially fatal disease that is of great global public health concern. The outbreak of COVID-19 is wreaking havoc worldwide due to inadequate risk assessment regarding the urgency of the situation. The COVID-19 pandemic has entered a dangerous new phase. When compared with SARS and MERS, COVID-19 has spread more rapidly, due to increased globalization and adaptation of the virus in every environment. Slowing the spread of the COVID-19 cases will significantly reduce the strain on the healthcare system of the country by limiting the number of people who are severely sick by COVID-19 and need hospital care. Hence, the recent outburst of COVID-19 highlights an urgent need for therapeutics targeting SARS-CoV-2. Here, we have discussed the structure of virus; varying symptoms among COVID-19, SARS, MERS and common flu; the probable mechanism behind the infection and its immune response. Further, the current treatment options, drugs available, ongoing trials and recent diagnostics for COVID-19 have been discussed. We suggest traditional Indian medicinal plants as possible novel therapeutic approaches, exclusively targeting SARS-CoV-2 and its pathways.
The potential health benefits of olive oil consumption, particularly within the context of the Mediterranean diet, have been extensively investigated. However, its specific health benefits remain to be confirmed. The aim of the present work is to review the scientific evidence regarding the specific impact of olive oil consumption on human health, including the prevention of cardiovascular disease, cancers, and diabetes mellitus. Ten related meta-analyses were reviewed to this effect. Olive oil consumption was found to be beneficial for several chronic non-communicable diseases (e.g. including cardiovascular disease, breast cancer and type 2 diabetes), whereas there were contradictory findings regarding its impact on several biomarkers. In conclusion, the aggregated evidence supports the assertion that olive oil consumption is beneficial for human health, and particularly for the prevention of cardiovascular diseases, breast cancer, and type 2 diabetes mellitus.
This chapter encompasses certain important phytochemical and pharmacological aspects of garden cress seeds (. Lepidium sativum Linn.). Lepidium sativum seed extracts are used as an antirheumatic, diuretic, and febrifuge; in abdominal discomfort; in fracture healing; and in the treatment of gout. These medicinal uses of LSS are practiced routinely in Ayurveda. These seeds have been implicated in the treatment and management of a plethora of diseases such as asthma, pain, inflammation, nociception, blood coagulation, oxidative stress, anuresis, and related disorders. The presence of various important phytochemical constituents in LSS (namely, alkaloids, flavonoids, cardiotonic glycosides, coumarins, glucosinolates, saponins, sterols, sinapic acid, tannins, triterpene, and uric acid) might be responsible for its ethnopharmacological, preclinical, and clinical recognition. Volatile oil obtained by steam distillation of LSS is also reported to exhibit an estrogenic effect and possesses antioxidant potential. These phytoconstituents of LSS might be responsible for its known as well as unknown pharmacological potential, which may provide novel phytoconstituents that can be evaluated for probable bioactivity. Extensive work has to be carried out for the isolation of novel bioactive compounds from LSS to ascertain their ethnopharmacological and new therapeutic potential.
Background
Sage (Salvia officinalis L.) has a wide range of biological activities, such as anti-oxidative properties, anti-bacterial, hypoglycemic, anti-inflammatory, fungistatic, virustatic, astringent, eupeptic and anti-hydrotic effects. This study was designed to examine the antidiabetic effect of sage ethanolic extract in normal and streptozotocin-induced diabetic rats.Methods
Oral administration of sage extract (0.1, 0.2, and 0.4 g/kg body weight) and glibenclamide (600 μg/kg) for 14 days on the level of serum glucose, triglycerides, total cholesterol, urea, uric acid, creatinine, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in normal and streptozotocin-induced diabetic rats were evaluated.ResultsOral administration of 0.2 and 0.4 g/kg body wt. of the sage extract for 14 days exhibited a significant reduction in serum glucose, triglycerides, total cholesterol, urea, uric acid, creatinine, AST, ALT and increased plasma insulin in streptozotocin-induced diabetic rats but not in normal rats. Glibenclamide was used as reference and showed similar antidiabetic effect.Conclusions
It is concluded that the traditional use of S. officinalis as an antidiabetic agent is justified and that extracts from this plant show a dose-dependent activity which is comparable to the standard antidiabetic drug glibenclamide.
An attempt is made to review the prevalence of medicinal herb use in different societies and the various lines of evidence for its effectiveness for particular health needs and the alleviation of disease conditions.
Published scientifically collected data and anecdotal reports representing numerous populations are compiled and evaluated. Original research findings from Caribbean, American, and Caribbean-American samples are included in the comparisons.
Medicinal plant products have been successfully administered both externally and internally in several different forms for a wide range of health problems cross-culturally since prehistoric times. Certain toxic effects and contraindications have also been recorded.
Many botanical medications contain curative bioactive chemical ingredients which have proven to be valuable as primary or supplemental therapies when carefully applied. Further research will ultimately clarify their appropriate roles in the treatment of diseases and injuries as well as in preventive health maintenance.
