ABSTRACT
COVID-19 is an infectious disease caused by Severe Acute Respiratory Syndrome (SARS-CoV-2), causing a global health emergency as a pandemic disease. The lack of certain drug molecules or treatment strategies to fight this disease makes it worse. Therefore, effective drug molecules are needed to fight COVID-19. Non Structural Protein (NSP5) or called Main Protease (Mpro) of SARS CoV 2, a key component of this viral replication, is considered a key target for anti-COVID-19 drug development. The purpose of this study is to determine whether the compounds in the Melaleuca leucadendron L. plant such as 1,8-cineole, terpene, guaiol, linalol, a-selinenol, beta-eudesmol and P-eudesmol are predicted to have antiviral activity for COVID-19. Interaction of compounds with NSP5 with PDB code 6WNP analyzed using molecular docking with Molegro Virtual Docker. Based on binding affinity, the highest potential as an anti-viral is Terpineol with binding energy (-119.743 kcal/mol). The results of the interaction showed that terpinol has similarities in all three amino acid residues namely Cys 145, Gly 143, and Glu 166 with remdesivir and native ligand. Melaleuca leucadendron L. may represent a potential herbal treatment to act as: COVID-19 NSP5, however these findings must be validated in vitro and in vivo.
ABSTRACT
The goal of this study is to assess the potential of cultivating plant-based raw materials in Mecklenburg-Vorpommern from the perspective of the pharmaceutical industry and to discuss the factors that could hinder the realization of high-quality cultivation. Procuring high-quality plant-based materials is crucial for the production of plant-based medicines, and the pharmaceutical industry has faced increasing challenges in sourcing these materials in recent years. The methodology involved surveying pharmaceutical companies that are members of the German Pharmaceutical Industry Association and are involved in the fields of homeopathic/anthroposophic medicines and plant-based pharmaceuticals. An online questionnaire was used to collect data. According to the pharmaceutical industry's perspective, there is growing demand for plant-based raw materials from domestic cultivation. Stable supply chains, quality, and reliability are seen as primary advantages over foreign cultivation. Geopolitical conflicts, climate change, and the COVID-19 pandemic have negatively affected the stability of supply chains for imported goods. 73% of companies reported encountering import difficulties multiple times. The majority of pharmaceutical companies can envision increased cooperation with agricultural enterprises in Mecklenburg-Vorpommern. Sustainability in sourcing was already deemed significant by more than two-thirds of the respondents. The study concludes that the importance of sustainable pharmaceutical production, stable supply chains, and high-quality plant-based raw materials will continue to grow. Mecklenburg-Vorpommern provides favorable conditions to meet a portion of the demand. To fully utilize the theoretical potential, close collaboration between the industry, academia, and policymakers is needed, along with minimizing regulatory and bureaucratic barriers for agricultural enterprises.
ABSTRACT
The world has faced huge challenges throughout the endemic of COVID-19. The survivors of Covid too are facing health difficulties. The non-availability of specific treatments made researchers search for all the possible treatment regimens including traditional medicines. India has the greatest culture of Ayurveda. Indian government's AYUSH ministry has granted permission for use of ancient systems of medicine for treatment of some of the COVID-19 cases, especially which are not at advanced stages. Along with this certain reports are there which have shown the positive outcomes of Ayurvedic treatment of COVID-19. However, it is more beneficial to build the immune system of the host from a large population and its health perspective to avoid widespread infection and control the potency of the infectious viral particles. A vaccine can offer protection by boosting specific immunity in the host at the same time non-specific ways to improve host immunity are suggestible. This has carved a path for the use of ancient Indian therapeutic methods such as Ayurveda and Yoga. Although there are many general articles where the home remedies have suggested but, more scientific references are required to document the ayurvedic medicines for Covid related ailments. In this review, an attempt is made to organize available evidences of usefulness of Ayurveda, Yoga, in COVID-19.
ABSTRACT
The novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began in Wuhan, China, in December 2019 and quickly spread across the worldwide. It becomes a global pandemic and risk to the healthcare system of almost every nation around the world. In this study thirty natural compounds of 19 Indian herbal plants were used to analyze their binding with eight proteins associated with COVID -19. Based on the molecular docking as well as ADMET analysis, isovitexin, glycyrrhizin, sitosterol, and piperine were identified as potential herbal medicine candidates. On comparing the binding affinity with Ivermectin, we have found that the inhibition potentials of the Trigonella foenum-graecum (fenugreek), Glycyrrhiza glabra (licorice), Tinospora cordifolia (giloy) and Piper nigrum (black pepper) are very promising with no side-effects.
ABSTRACT
Facing the unprecedented burden and rapid spread of the Covid-19 pandemic across the globe, responses from various regions have been exceptionally quick. Drug discovery has been essentially based on repurposing, particularly at the onset of the scourge. Several experimental models have been designed ranging from in vitro cell culture systems to nonhuman primates;however, each with advantages and limitations. It was revealed beside its detrimental consequences on health, economy and the society, Covid-19 has also provided opportunity to highlight the immense potential of traditional medicine as a valid alternative for addressing major health threat. The African traditional medicine has been instrumental for the control of the COVID-19 pandemic in the continent, in situation of extremely low vaccination coverage. For optimal and sustainable use of traditional medicine, we strongly recommend products be developed following the WHO standards, while taking into consideration sustainability, environmental protection and copyright issues surrounding the natural product-based drug research and development.
ABSTRACT
Many studies have dealt with the medicinal properties of Jatropha curcas;however, there are limited studies on the scope of its antiviral potential. This is a fact associated with the current challenges posed by HIV-AIDS and COVID-19, which has reinforced the need to expand the knowledge about its antiviral resource. Based on the search for natural products with anti-HIV-1 and anti-SARS-CoV-2 activities, this work analyzed the extract of J. curcas seed, the structure of the plant whose antiviral references were not found in the literature, and the compounds that can potentiate it as a candidate for herbal medicine. GC-MS analysis was used to screen for the active substances of the J. curcas seeds, and the literature was searched to find those with anti-HIV-1 and anti-SARS-CoV-2 indication. The results showed they have 27 compounds, of which glycerol 1-palmitate, stigmasterol and gamma-sitosterol were shown to have antiviral action in the literature. Regarding glycerol 1-palmitate, no detailed description of its antiviral action was found. Stigmasterol and gamma-sitosterol act as anti-HIV-1 and anti-SARS-CoV-2, respectively, inhibiting the reverse transcriptase of HIV-1, the proteases 3CLpro, PLpro and the spike proteins of SARS-CoV-2. However, despite the fact that the extract of J. curcas seeds consist of antiviral compounds that fight against the etiological agents of HIV-AIDS and COVID-19, it is concluded that there is a need to deepen this evidence, by in vitro and in vivo assays.
ABSTRACT
The taxonomic diversity and the richness of the region of Seraidi (North-East Algeria) in medicinal plants, as well as the appearance of diseases of viral origin, in particular, the current pandemic of SARS-CoV-2, led us to the realization of an ethnobotanical survey of plants with antiviral interests. The survey was conducted based on a pre-established quiz, with 120 people from different categories of the population of Seraidi, with the aim of listing the medicinal plants used in the treatment of viral diseases and collecting as much information as possible on this subject. After analyzing, the information provided by the people interviewed, we listed 32 species belonging to 20 families, of which the Lamiaceae family is the most represented. Older women are the most affected by the use of plants;people without a higher intellectual level have the most knowledge about the use of plants with antiviral interest. The leaf is the most widely used organ, in the form of a decoction or infusion, administered orally.
ABSTRACT
Aim: The contagious disease COVID 19 is a recently out-broken pandemic situation which threatens humankind all over the world. Siddha system of medicine is one of the traditional medical systems of India, which has provided a novel remedy for many epidemics like Dengue, Chicken guinea earlier. On evaluating the literature evidence and considering the mortality and severity of the disease, we have attempted to identify the possible inhibition of viral replication by "Karisalai Chooranam" - a polyherbal Siddha formulation which contains herbs like Karisalai (Wedelia chinensis), Thoodhuvelai (Solanum trilobatum), Musumusukai (Melothria maderaspatana) and Seeragam (Cuminum cyminum). The aim of this study was to identify the bioactive components present in Karisalai chooranam and pin down the components that inhibit COVID 19 protease by In Silico molecular docking analysis. Material and methods: The study was performed for the active compounds present in the herbs (Wedelia chinensis - Benzoic acid, Solanum trilobatum- Disogenin, Melothria maderaspatana- beta-sitosterol, Cuminum cyminum L- Coumaric acid and Limonene) with three potential targets, PDB id: 6LU7 3-chymotrypsin-like protease (3CLpro), PDB id: 6-NUR RNA dependent RNA polymerase and PDB id: 2AJF Angiotensin-converting enzyme II (ACE2) receptor using Autodock Vina. Key findings: The active phytocomponents present in "Karisalai chooranam" was found to inhibit the target 3CL proenzyme and hereby halt the formation of 16 non-structural proteins (nsp1-nsp16) that are highly essential for viral replication and there by prevents viral survival in the host environment. The phytocomponents also inhibited the target RNA dependent RNA polymerase (PDB)-6NUR RdRp which possess versatile action in mediating nonstructural protein (nsp 12) essential for viral replication. A significant binding against the target Angiotensin-converting enzyme II (ACE2) receptors - PDB- 2AJF was found which was recognized as a binding site for novel coronavirus to cause its pathogenesis. Among the five active components present in the herb, the binding ability of Disogenin and beta-sitosterol with COVID19 protease suggests a possible mechanism of protease inhibition and thus preventing viral replication. Significance: The results strongly suggest that phytocomponents of "Karisalai chooranam" may act as a potential therapeutic agent for the management of COVID-19 and related symptoms. Further, the efficacy of the active compounds should be tested in vitro before being recommended as a drug.

ABSTRACT
During the current COVID-19 outbreak, Thai traditional antipyretic recipes and antipyretic herbs have been widely studied. Antipyretic Thai/Lanna herbal decoction for relieving fever in the North consists of Tinospora crispa, Rhinacanthus nasutus, Sauropus androgynus and Alstonia scholaris. This research aimed to study the physical stability, pH, sedimentation, and color of the Lanna antipyretic decoction at 4 degrees C 25 degrees C and 40 degrees C with 75 +or- 5% RH for 7 days. The testing included the Folin Ciocalteu method for quantifying total phenolic content, the aluminium chloride colorimetry for flavonoid content, and the DPPH radical scavenging and ABTS methods for antioxidant activities. The results demonstrated that, for the decoction, the pH values at various temperatures dropped with storage time, the sediment amounts increased with storage time, but its color did not change at 4 degrees C. Its total phenolic and flavonoid contents rose with storage time. The total phenolic contents in mg GAE/g extract at Days 0 and 7 were 161.13 +or- 5.62 and 15.34 +or- 6.21 at 4 degrees C, 160.53 +or- 11.78 and 14.32 +or- 1.13 at 25 degrees C, and 160.09 +or- 7.39 and 12.82 +or- 6.91 at 40 degrees C, respectively;while the flavonoid contents in mgQE/g extract at Days 0 and 7 were 20.32 +or- 0.43 and 7.80 +or- 0.34 at 4 degrees C, 20.10 +or- 0.47 and 7.27 +or- 0.20 at 25 degrees C, and 20.06 +or- 0.55 and 6.63 +or- 0.43 at 40 degrees C, respectively. The decoction's free radical inhibition (IC50) values at 4 degrees C, 25 degrees C and 40 degrees C by DPPH ranged from 14.74 +or- 0.04 to 23.18 +or- 0.72%w/w;and by ABTS the values ranged from 2.63 +or- 0.12 to 3.95 +or- 0.05%w/w. At the storage temperature of 4 degrees C, the decoction showed the best physical stability. Thus, the results can be used in setting up storage guidelines for Thai traditional and folk decoctions to ensue the best stability.
ABSTRACT
Objective: To explore the effect and mechanism of Xuanfei Jiere Granules in the treatment of corona virus disease 2019 (COVID-19) complicated with fever. Methods: The effective components of Xuanfei Jiere Granules were screened by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), and the potential target genes were predicted. The disease targets of COVID-19 complicated with fever were searched by GeneCards and CTD databases, and the common targets were obtained, and then introduced into Cytoscape to construct the "component-target-disease" network. The above 2 common targets were input into the online database of STRING protein interaction, and the results were imported into Cytoscape software to obtain Protein-Protein Interaction(PPI) network;R language was used to analyze the common targets with Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analysis. Results: 84 active components and 82 targets were obtained. The pathway enrichment analysis showed that Xuanfei Jiere Granules mainly acted on protein kinase B(AKT1), tumor protein P53(TP53), interleukin-6(IL6) and other key targets in the treatment of COVID-19 complicated with fever. KEGG pathway enrichment analysis showed that the action was mainly related to the influence of fluid shear stress and atherosclerosis, human cytomegalovirus infection, and AGE-RAGE in diabetic complications and other signal pathways. The results of molecular docking showed that the core target had strong affinity with beta-sitosterol, formononetin, N-trans ferulyl tyramine and so on. Conclusion: This study preliminarily verified that Xuanfei Jiere Granules can play a role in the treatment of COVID-19 complicated with fever through multi-components, multi-targets and multi-pathways.
ABSTRACT
Background: Research began on botanical/herbal organisms to study plant cells. The idea behind this was that plant cells have basic similar actions as do animal cells (i.e., both are Eukaryotic cells). These cells can show what activity is produced from the Technology/Innovation behind ImunStem, without risk to animals or humans, and still retrieve data to verify the theory. By using plants and studying plant cell activity, then later comparing plant cell, animal cells, and human cell responses, it thus shows activity for all cell structures. The activity was also studied from patients taking ImunStem for the indication of Serious or Life-threatening conditions or diseases. Patient medical report results showed an overall improvement in bodily function as blood report results were compared. Patients that were administered ImunStem showed improvement in their overall health and patients with chronic disease had reduced pain as ImunStem was administered over time. The pain was reduced because the body was in the healing process and a reduction in inflammation would occur during healing and the patient's health would improve. ImunStem was produced based on the theory that the product could rejuvenate the cell and bring the cell back to a homeostasis balance. This balance to the cell (through nutrition) can give the surrounding cells a homeostasis balance that may heal cells and tissues in the body. It is believed that the function of a Quantum Wave effect is explained through the discipline of Quantum Mechanics. The Quantum Wave may disrupt the subatomic particles that provide adhesion to allow the product through the cell wall and move to its target location. In Quantum Mechanics, particles have wavelike properties. The Schrodinger equation, for example, governs how these waves behave. Methods: Administration of ImunStem was given to patients in a life-threatening situation where no standard acceptable treatment was available and in which there was not sufficient time to obtain approval from the Institutional Review Board. Results: ImunStem showed positive medical results for patients with Serious or Life-threatening conditions or diseases, which prompted the US Food and Drug Administration (FDA) to move forward so patients could be provided treatment that was not otherwise available to them from their physicians/doctors. ImunStem was applied for and received its New Drug Application (NDA) No.: 204701 with the indication of Serious or Life-threatening conditions or diseases and National Drug Code (NDC) No.: 70642-001-01 on July 02, 2018. Golden Sunrise submitted an NDA application on January 07, 2013, November 05, 2018, and April 03, 2020 with a request for FDA Fast Track designation, Breakthrough Therapy designation, Accelerated Approval designation, and Priority Review program process are the pathway allowing the ImunStem product to receive acceptance by the FDA.
ABSTRACT
Background: Antiviral vaccine is not effective, synthetic antiviral drugs are highly toxic, leading to increased interest in herbal medicines as promising antiviral drugs. Recently, Vipdervir has been developed from medicinal herbs with the aim to support and treat diseases caused by viruses such as H5N1 and SARSCoV- 2. In the present study, we assessed Vipdervir's antiviral activity against H5N1 and SARS-CoV-2. In addition, we also evaluated the acute toxicity and repeated dose toxicity of Vipdervir in mice and rabbits, respectively. Methods: H5N1 inhibitory effect of Vipdervir was assessed using hemagglutination inhibition assay. Vipdervir's SARS-CoV-2 inhibitory effect was evaluated by Plaque Reduction Neutralization assay. Acute and repeated dose oral toxicities of Vipdervir were determined according to OECD 423 and OECD 407 guidelines, respectively. Results: Data show that Vipdervir is effective against both H5N1 and SARSCoV- 2. At concentrations of 3 mg/mL and 5 mg/mL Vipdervir completely inhibits H5N1. At a concentration of 50 g/mL Vipdervir showed an inhibitory effect on SARS-CoV-2. Acute toxicity data revealed that the LD50 of Vipdervir is greater than 35200 mg/kg, b.wt. in mice. Repeated toxicity data indicated that Vipdervir did not induce significant differences in body weight gain, hematology and clinical biochemistry in compared to the control group. The No Observed Adverse Effect Level of Vipdervir is greater than 613.8 mg/kg b.wt./day in rabbits. No delayed toxicity effects of Vipdervir were observed. Conclusion: Vipdervir capsules were found to be antiviral effective and relatively safe in the tested doses and experimental conditions.
ABSTRACT
Currently, the world is facing a Coronavirus pandemic with a grave deficiency of specific therapy for Coronavirus Disease (COVID-19). Moreover, scientists attempt to discover the most refined approach to prevent this condition. Regarding COVID-19 infection, herbal medicines with immunomodulatory effects may offer patients a promising preventive treatment option. Several ayurvedic and Traditional Chinese Medicine (TCM) are effective during this worrisome Coronavirus pandemic i.e. Tinospora cordifolia (Willd.) Miers, Withania somnifera (L.) Dunal, Scutellaria baicalensis Georgi, Curcuma longa L. etc. TCM was shown to be utilized with over 90% efficacy when the COVID-19 pandemic broke out in early 2020. In addition to herbal treatments and nutraceutical drugs, dietary supplements such as vitamins and amino acid derivatives also play a significant part in COVID-19 management. Diet can assist in regulating inflammation, while nutraceuticals can aid in the prevention of viral invasion. Functional amino acids (e.g., arginine, cysteine, glutamate, glutamine, glycine, taurine, and tryptophan) and glutathione, which are all abundant in animal-sourced foodstuffs, are crucial for optimum immunity and health in humans and animals. The goal of this article is to thoroughly evaluate recent statistics on the effectiveness of herbal medicines in COVID-19, the antiviral activity of nutraceuticals, and the significance of these results in creating dietary supplements that would enhance innate immunity and contribute as preventive measures against severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2).
ABSTRACT
Herbal drug therapy is a beneficial and easily accessible modality of treatment.Pharmacist can play a pivotal role in rationalizing its use. This study was aimed to assess the knowledge and perception ofpharmacy students regarding herbal drugs.We conducted a cross-sectional survey using avalidated study instrument. The survey included pharmacy students from various universities across Pakistan.There were 342 (54.3%) 4(t)h yearand 288 (45.7%) 5(th) year students. We found statistically significant variations (p < 0.05) in the knowledge of male and female respondentsregarding;'the carminative use of Hyoscyamus niger' and 'effectiveness of Citrus aurantifolia in vomiting and chest burning'. Similarly, significant variations were found in perception of students regarding the 'inclusion of herbal drugs in every medical degree course', 'evidence-based herbal drugs use', and 'necessity of specific portion of herbal drugs in every pharmacy'. More than 40% of students agreed that it was fine to use Senna alexandrina during COVID-19 pandemic-era without evidence-based studies.The knowledge of pharmacy students about herbal drugs is not satisfactory and evidence-based drug use is to be improved to enhance their skills in the rational therapy of herbal drugs, which will be fruitful in managing the community's disease conditions.
ABSTRACT
Coronavirus disease COVID-19 is causing havoc globally, infecting millions of people and has led to the deaths of people in thousands. COVID-19 attacks persons with low immune sys-tems, especially neonates and geriatrics. Hence, boosting immunity may be one of the best options during this pandemic. There is a need to explore the possible herbal drugs to boost the immunity of people as a result of the rising cases of deaths due to COVID-19. However, the rationale for the use of herbal drugs is that each herb has the possibility of treating many health conditions. A single herb could have antiviral, antibacterial, and anti-inflammatory properties. Herbs may be one possible source of a true cure for COVID-19. Herbal drugs are from renewable sources and pose less danger of possible adverse effects compared to synthetic drugs. Because COVID-19 has no true cure pres-ently, man should resort to herbal drugs given by nature. Herbal drugs are highly potent and effica-cious;hence, the early men treated their ailments with herbs. However, their use has been limited by poor pharmaceutical design into dosage forms that would be acceptable to people. Herbal drugs could be formulated as teas, decoctions, infusions, and, more recently, tablets, capsules, microparti-cles, nanoparticles, and phytosomes, amongst others. Different herbal plants with possible immune booster effects will be discussed in this work, and how they can be formulated into stable and acceptable dosage forms will be explored.

ABSTRACT
The coronavirus disease 2019 (COVID-19) was a newly discovered infectious respiratory disease and characterized by wide prevalence, high incidence rate and fast progress, which belonged to the category of "cold-wet plague" in traditional Chinese medicine. The onset of COVID-19 was caused by pestilence, which mingled with seasonal cold-dampness and invaded the human body when external defensive qi was weak and then leaded to the accumulation of Yang qi. Different from exogenous pathogenic factors transmitted from the external to the internal or followed the transmission law of Wei, Qi, Ying and Xue, the nature of pestilence belonged to the category of pathogenic fire, spreading as soon as possible, from the external to the internal and from the upper and lower part of triple energizer, even to every part. At the very beginning, the pestilence attacked from the Taiyang meridian into the Yangming meridian quickly, or straight into the three Yang meridian, which was called "triple-yang combination of diseases". Manifestations of fever, aversion to cold and pain of body were conformed to the exterior syndrome of Taiyang, as well as manifestations of fullness and discomfort in chest, vomiting and spitting and diarrhea were conformed to the syndrome of half-interior half-exterior;And symptoms manifested as high fever, faint, and abdominal fullness and constipation were conformed to the syndrome of Yangming;But sometimes, there was cold-dampness surrounding the exterior at the beginning along with intense interior pathogenic fire. Or at the beginning, the exterior factors invaded into three Yin meridians quickly while have not been eliminated, which may lead to the syndrome of inner blocking causing collapse or Jue exhaustion. The most typical syndrome of COVID-19 was triple-yang combination of diseases, which was often seen in mild, moderate and part of severe cases. Hence "Qingfei Paidu Decoction" was prescribed especially for this kind of syndrome. Its accurate efficacy has been proved by that mild cases converting to severe cases in the mobile cabin hospital have been effectively restrained and thus the progression of the disease has blocked. Composition analysis showed that Mahuang decoction with Maxing Shigan decoction was to relieve exterior Taiyang syndrome, Xiaochaihu decoction was for harmonizing half-superficies and half-interior Shaoyang syndrome, and large dose of gypsum was used to clear interior heat of the Yangming meridian, and Shegan Mahuang decoction and Xiaoqinglong plus gypsum decoction was for lowering the adverse qi and resolving fluid, and Wuling San was for warming the triple energizer and transforming qi and draining water. "Qingfei Paidu Decoction" was a syncretic innovation of classical prescriptions from Treatise on Febrile Diseases, which was not made up of herbs but multiple concordant prescriptions helping to get twice the result with half the effort, so that the "cold-wet plague" can be quickly discharged.
