Anti-pathogenic potential of a classical ayurvedic Triphala formulation.

ABSTRACT: A classical ayurvedic polyherbal formulation namely Triphala was assessed for its anti-pathogenic potential against five different pathogenic bacteria. Virulence of four of them towards the model host Caenorhabditis elegans was attenuated (by 18-45%) owing to pre-treatment with Triphala Formulation (TF) (?20 µg/ml). TF could also exert significant therapeutic effect on worms already infected with Chromobacterium violaceum (MTCC 2656), Serratia marcescens (MTCC 97) or Staphylococcus aureus (MTCC 737). Prophylactic use of TF allowed worms to score 14-41% better survival in face of subsequent pathogen challenge. Repeated exposure to this formulation induced resistance in S. marcescens, but not in P. aeruginosa. It also exerted a post-extract effect (PEE) on three of the test pathogens. TF was able to modulate production of quorum sensing (QS)-regulated pigments in three of the multidrug-resistant gram-negative test bacteria. Haemolytic activity of S. aureus was heavily inhibited under the influence of this formulation. P. aeruginosa's lysozyme-susceptibility was found to increase by ~25-43% upon TF-pretreatment. These results validate therapeutic potential of one of the most widely used polyherbal ayurvedic formulations called Triphala.

Project description:BackgroundWhile Molnupiravir and Paxlovid have recently been approved for use in some countries, there are no widely available treatments for COVID-19, the disease caused by SARS-CoV-2 infection. Herbal extracts have been used to treat respiratory clinical indications by Ayurvedic medicine practitioners with minimal adverse reactions and intense research efforts are currently under way to develop some of these formulations for COVID-19 treatment.MethodsLiterature search for in silico, in vitro, in vivo, and clinical studies on the topic of Ayurvedic formulations for potential COVID-19 treatment, in order to present the current state of current knowledge by integrating information across all systems.ResultsThe search yielded 20 peer reviewed articles on in silico studies examining the interaction of phytoconstituents of popular Ayurvedic formulations with SARS-CoV-2 components and its receptors; five articles on preclinical investigations of the ability of selected Ayurvedic formulations to inhibit functions of SARS-CoV-2 proteins; and 51 completed clinical trials on the efficacy of using Ayurvedic formulations for treatment of mild to moderate COVID-19. Clinical data was available from 17 of the 51 trials. There was a considerable overlap between formulations used in the in silico studies and the clinical trials. This finding was unexpected as there is no clearly stated alignment between studies and the traditional pathway to drug discovery- basic discovery leading to in vitro and in vivo proof of concept, followed by validation in clinical trials. This was further demonstrated in the majority of the in silico studies where focus was on potential antiviral mechanisms, while the clinical trials were focused on patient recovery using oral treatments. In all 17 clinical trials where data was available, Ayurvedic treatments lead to a shorter period to recovery in participants with COVID-19.ConclusionThe most commonly used Ayurvedic treatments for management of respiratory symptoms associated with SARS-CoV-2 infection appear to have prophylactic and/or therapeutic properties. It would be of particular interest to assess synergistic and concomitant systemic effects and antiviral activities of individual phytoconstituents and their combinations in the Ayurvedic treatments.

Project description:BackgroundNayopayam kwatha (NK) is a well-known polyherbal formulation widely used to cure respiratory ailments, heart problems, and postnatal difficulties. Literature suggests that so far no standardization protocol was developed for NK to validate its quality and purity.Objective(s)To develop a standardization protocol for NK based on the marker phytoconstituents present in the individual herbs of the formulation.Materials and methodsThe roots of bala [Sida cordifolia (B1) and Sida retusa (B2)], seeds of jeeraka (Cuminum cyminum), and rhizomes of nagara (Zingiber officinale) were the ingredients of NK. Since there were two source plants for bala, two sets of NK (NKB1 and NKB2) were prepared in the ratio 3:2:1 as per Vaidya Manorama and 10:1:1 as per Arogyaraksha Kalpadruma along with 1:1:1 as per the general way of Ayurvedic polyherbal decoctions. Both the individual herbs and the kwatha (decoction) prepared were analyzed in terms of pharmacognostical, organoleptic, and physcicochemical parameters as per the standard methods. Phytochemical analysis of the individual herbs resulted in the isolation of major phytoconstituents and the kwatha was quantified in terms of marker compounds with the aid of HPLC.ResultsHPLC quantification suggests that appreciable amount of marker phytoconstituents of individual herbs are present in the kwatha. Thus, the isolated compounds luteolin (C. cyminum), 6-gingerol (Z. officinale), β-sitosterol (S. retusa), and ecdysterone (S.cordifolia) can be used as markers to standardize NK.ConclusionCharacteristics of NK, as well as its individual drugs, were well-established. The present study of NK with respect to its phytochemistry revealed that the classical drug ratios of the polyherbal formulation are of utmost importance rather than the ingredients in equal proportion. The characterization parameters of individual herbs and kwatha described in this study may serve as a standard reference for quality control analysis of NK and the method developed in this study can be used as a reliable technique for standardization of NK to ensure the purity and quality of raw drugs used.
