Evidence-based traditional Siddha formulations for prophylaxis and management of respiratory symptoms in COVID-19 pandemic-a review

Exploring Bioactive Phytomedicines for Advancing Pulmonary Infection Management: Insights and Future Prospects

Pulmonary infections have a profound influence on global mortality rates. Medicinal plants offer a promising approach to address this challenge, providing nontoxic alternatives with higher levels of public acceptance and compliance, particularly in regions where access to conventional medications or diagnostic resources may be limited. Understanding the pathophysiology of viruses and bacteria enables researchers to identify biomarkers essential for triggering diseases. This knowledge allows the discovery of biological molecules capable of either preventing or alleviating symptoms associated with these infections. In this review, medicinal plants that have an effect on COVID-19, influenza A, bacterial and viral pneumonia, and tuberculosis are discussed. Drug delivery has been briefly discussed as well. It examines the effect of bioactive constituents of these plants and synthesizes findings from in vitro, in vivo, and clinical studies conducted over the past decade. In conclusion, many medicinal plants can be used to treat pulmonary infections, but further in-depth studies are needed as most of the current studies are only at preliminary stages. Extensive investigation and clinical studies are warranted to fully elucidate their mechanisms of action and optimize their use in clinical practice.

In silico network pharmacology analysis and molecular docking validation of Swasa Kudori tablet for screening druggable phytoconstituents of asthma

Traditional medicines are impactful in treating a cluster of respiratory-related illnesses. This paper demonstrates screening active, druggable phytoconstituents from a classical Siddha-based poly-herbal formulation called Swasa Kudori Tablet to treat asthma. The phytoconstituents of Swasa Kudori are identified as Calotropis gigantea, Piper nigrum, and (Co-drug) Abies webbiana. Active chemical compounds are extracted with the Chemical Entities of Biological Interest (ChEBI) database. The gene targets of each compound are identified based on the pharmacological activity using the DIGEP-Pred database. Thirty-two genes showing Pa> 0.7 is screened, and the target markers are selected after performing gene overlap evaluation with the asthma genes reported in GeneCards and DisGeNET database. Ten markers are identified, such as ADIPOQ, CASP8, CAT, CCL2, CD86, FKBP5, HMOX1, NFE2L2, TIMP1, VDR, in common, listed as molecular targets. Pharmacokinetic assessment (ADME) revealed five natural drug compounds 2-5-7-trihydroxy-2-(4-hydroxyphenyl)-2,3-dihydro-4H-chromen-4-one, (+)-catechin-3'-methyl ether, futoenone, 5-hydroxy-4',7-dimethoxyflavanone, and pinocembrin showing better druggability. Further screening delineates the target (HMOX1) and drug (pinocembrin) for molecular docking evaluation. When docked with HO-1, Pinocembrin showed a binding affinity of -8.0 kcal/mol. MD simulation studies substantiate the docking studies as HO-1 in complex with pinocembrin remains stable in the simulated trajectory. The current findings exhibit the significance of traditional medicines as potential drug candidates against asthma.

Safety and efficacy of Siddha management as adjuvant care for COVID-19 patients admitted in a tertiary care hospital - An open-label, proof-of-concept Randomized Controlled Trial

Background

COVID-19 resulted in loss of human lives owing to respiratory failure caused by dysregulated immune system. Though many treatments are evaluated, the most appropriate is yet to be established.

Objective

To determine the safety and efficacy of Siddha add-on therapy in COVID -19 in terms of accelerated recovery, reduced hospital stay & mortality and follow up assessment of post discharge status until 90 days as compared to the Standard Care management.

Methods

In a randomized, controlled, single-center, open-label trial conducted on 200 hospitalized COVID-19 patients, they were allocated equally to be treated with add-on Siddha regimen with Standard care or only Standard care. Standard care was in accordance to the Government norms. Recovery was defined as amelioration of symptoms, viral clearance and attaining SpO2 > 94% in room air indicating the derived score of zero on WHO clinical progression scale. The primary and secondary end points were accelerated recovery (≤ 7 days) and mortality comparison between the groups respectively. Also, disease duration, length of hospital stays and laboratory parameters were assessed for safety and efficacy. Patients were followed through for 90 days after admission.

Results

In this study the accelerated recovery was 59.0% and 27.0% in treatment and control groups (ITT analyses) (p < 0.001) respectively and Odds for it were four times higher in the treatment group (OR: 3.9; 95% CI: 1.9, 8.0). The estimated median time for recovery in the treatment group was 7 days (95% CI: 6.0, 8.0; p=0.003) and 10 days (95% CI: 8.7, 11.3) in control. Hazard ratio for death in control was 2.3 times that of treatment group. No adverse reactions or alarming laboratory values were observed in response to intervention. In Severe COVID treatment group (n=80), mortality was 15.0% and 39.5% in control (n=81). The COVID stage progression was 65% less in test group. Mortality during treatment and 90 days follow up in Severe COVID patients were 12 (15%) and 35 (43.2%) in treatment and control groups respectively.

Conclusion

The selected Siddha regimen when co-administered with Standard of Care have demonstrated that they can synergistically act to improve oxygenation status of patients, enhance the recovery rate from COVID-19 and reduce the mortality better when compared to administration of only Standard of Care.

Public Health and the Politics of Knowledge: The Role of Traditional Medicine in the Management of COVID-19 in Two South Indian States

Public health discourse about COVID-19 pandemic has mostly been framed around biomedical interventions, although there is evidence of the effective use of traditional medicine (TM) to manage the pandemic by some Asian countries such as China, Thailand, Vietnam and India. This article aims to place on record the policy of medical pluralism in the two South Indian states of Tamil Nadu and Kerala in their respective deployment of Siddha and Ayurveda in the management of COVID-19. Based on interviews with physicians of TM and health administrators, press reports, social media posts and published research, this article reconstructs the crucial yet undocumented process of incorporating TM in the biomedicine-based health bureaucracy in Tamil Nadu and Kerala to deal with infectious fevers such as dengue and chikungunya in the past and COVID-19 in the present. It is our argument that those methods of TM which are safe and in long recent use could provide low-cost and accessible means of prevention and early treatment of infectious fevers. They have to be identified and subjected to further investigation as innovations in social medicine brought forth by the state and its officials and are different from the highly expensive projects of the corporate pharmaceutical sector.

A Review of Different Vaccines and Strategies to Combat COVID-19

In December 2019, an unknown viral infection emerged and quickly spread worldwide, resulting in a global pandemic. This novel virus caused severe pneumonia and acute respiratory distress syndrome caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). It has caused 6.25 millions of deaths worldwide and remains a major concern for health, society, and the economy. As vaccination is one of the most efficient ways to combat this pandemic, different vaccines were developed in a short period. This review article discusses how coronavirus affected the top nations of the world and the vaccines being used for the prevention. Amongst the vaccines, some vaccines have already been approved, and some have been involved in clinical studies. The article also provides insight into different COVID-19 vaccine platforms, their preparation, working, efficacy, and side effects.
