Long COVID is characterized by persistent symptoms associated with chronic inflammation and oxidative stress. While high-intensity interval training (HIIT) and supplementation with antioxidants such as Triphala have demonstrated individual therapeutic benefits, their combined effects remain unclear. This study aimed primarily to evaluate the effects of an 8-week HIIT program on markers of inflammation, oxidative stress, and exercise-related symptoms in individuals with long COVID, and secondarily to explore whether Triphala supplementation provided additional benefits. A total of 104 participants (aged 18–59 years) were randomized into three groups—control (placebo), HIIT (cycling for 28 min/day, 3 days/week), and combined (HIIT + Triphala, 1000 mg/day)—for 8 weeks. The biomarkers assessed included interferon-gamma (IFN-γ), tumor necrosis factor-alpha (TNF-α), malondialdehyde (MDA), protein carbonyls, and superoxide dismutase (SOD) activity. Following the intervention, significant reductions in IFN-γ, TNF-α, MDA, protein carbonyls, and rating of perceived exertion were observed in both the HIIT and combined groups (p < 0.05), with no significant differences between the two. SOD activity significantly increased in all groups, including the control group (p < 0.05), with no between-group differences. An 8-week HIIT program appears to be effective in reducing inflammation, oxidative stress, and dyspnea in individuals with long COVID. Triphala supplementation did not provide any additional statistically significant benefit but was safe and well tolerated. Full article

Myrobalan fruits are important ingredients of traditional remedies, such as the Ayurvedic formulation Triphala or the Tibetan formulation Bras bu 3. Myrobalan-containing remedies are described to have positive effects on metabolism, the cardiovascular system, and the immune system. The chemical composition of botanical mixtures can be very complex, and it is often impossible to identify individual compounds as specific active ingredients, which suggests a multi-target mode of action. In this in vitro study, the effect of myrobalan extracts in human cell models was investigated to gain more information about the molecular mechanism of action and to find possible synergistic effects. Direct and indirect antioxidant effects were investigated, and the activation of immunobiochemical metabolic pathways involved in the cellular immune response was examined in cell lines treated with extracts of the fruits of Phyllanthus emblica, Terminalia chebula and Terminalia bellirica, as well as a combination of them. In particular, a synergistic effect on the activation of the endogenous antioxidant defence system was observed with the combined treatment of the three fruit extracts. An integrated transcriptome analysis of cells treated with a combination of fruit extracts confirmed an effect on immune pathways, oxidative stress, and detoxification processes. This study shows the modulation of various signalling pathways and cellular processes that may be part of the multi-target mechanism of individual and combined myrobalan fruit extracts. Although the results are limited to in vitro data, they contribute to a better understanding of how botanical mixtures work and provide hypotheses for further research. Full article

Oxidative stress plays a crucial role in chronic nasal disorders, contributing to inflammation, tissue damage, and impaired mucosal function, highlighting the need for targeted therapies. Recent advancements in nasal drug delivery systems have expanded their applications for treating respiratory and inflammatory conditions. Among these, hydrogel-based systems offer prolonged release of active pharmaceutical ingredients (APIs), enhancing therapeutic efficacy and reducing dosing frequency. This study initially evaluates the antioxidant, anti-inflammatory, antimicrobial, and cytotoxic properties of Nanotriphala, followed by its incorporation into a thermoresponsive in situ hydrogel system, which was subsequently developed and characterized as a novel formulation. Nanotriphala exhibited >90% cell viability and significantly reduced nitric oxide (NO) levels by 40.55 µg/mL at 250 µg/mL. The hydrogel was characterized by key parameters, including viscosity, gelling time, pH, gelling temperature, texture analysis, and ex vivo spreadability. Stability was assessed under various conditions, and mutagenicity and antimutagenicity were evaluated using the Ames test. Results showed that the hydrogel gelled at 34 °C, exhibited good spreadability (10.25 ± 0.28 cm), a viscosity of 227 ± 22 cP, and maintained a pH of 5.75 ± 0.01, with optimal hardness and adhesiveness suitable for nasal application. It demonstrated antimicrobial activity against E. coli, P. aeruginosa, S. aureus, and S. epidermidis at minimal bactericidal concentrations (MBCs) of 32, 2, 4, and 8 µg/mL, respectively, with low mutagenicity (mutagenic index < 2) and strong antimutagenic activity (>60%). The gallic acid content was 0.5796 ± 0.0218 µg/100 mL. Stability studies confirmed optimal storage at 4 °C. These findings suggest that in situ hydrogel loaded with Nanotriphala is a promising nasal drug delivery system for managing oxidative stress and related inflammatory conditions. Full article

Maha Pigut Triphala is the herbal mixture of three fruits consisting of T. bellirica, T. chebula, and E. officinalis also known as P. emblica. Humans regularly eat the fresh fruits of these plants on a daily basis. Maha Pigut Triphala is one of the widely known herbal medicinal formulas used in traditional Thai medicine. Besides studying pharmacological properties, attention should also be paid to the safety and toxicity studies of herbal medicines. The objective of the present study was to evaluate the acute and chronic oral toxicity of Maha Pigut Triphala (2:1:3) in Sprague-Dawley rats. A single dose of Maha Pigut Triphala at a concentration of 5000 mg/kg body weight was administered orally to female rats in the acute oral toxicity study. In the chronic oral toxicity study, male and female rats were treated with various concentrations of Maha Pigut Triphala (600, 1200, and 2400 mg/kg body weight) once daily for 270 consecutive days. The presence of abnormalities in the symptoms and behavior of the rats were observed and recorded throughout the experiment. Additionally, body weight, organ weight, and mortality were recorded. At the end of the study, blood samples were collected for hematological and blood chemistry analysis, while the internal organs were evaluated for gross pathological and histopathological changes. The acute oral toxicity study revealed no mortality and abnormal symptoms or behavior in Maha Pigut Triphala-treated rats. Moreover, gross pathological and histopathological findings did not reveal any abnormalities in the internal organs. In the chronic oral toxicity evaluation, although there were negligible changes in body weight, organ weight, and hematological and blood chemistry parameters in rats treated with Maha Pigut Triphala for 270 days, no behavioral or gross pathological and histopathological abnormalities were observed. Overall, the results of this study demonstrate that Maha Pigut Triphala (2:1:3) neither causes acute nor chronic oral toxicity in rats, proposing the safety of this herbal formula in animals prior to human trials and use.

Aim: The aim of this study was to evaluate and compare the efficacy of Triphala and chlorhexidine mouthwashes in reducing gingivitis and dental plaque in children. Methodology: A literature search was confined to the English language using MeSH terms conferring to PICO format in PubMed, Cochrane Library, and Ovid ^(SP), covering the period from January 1960 to August 2022. A search in Google Scholar and the grey literature and a hand search of references was performed to find additional data. Suitable studies were selected based on the predefined inclusion and exclusion criteria. Quality analysis of the selected studies was performed using the Cochrane Risk of Bias Tool for Randomized Controlled Trials. Results: Seven hundred and forty-seven articles were retrieved from three databases (PubMed, Cochrane Library, Ovid ^(SP), and other sources). Results: A total of 747 studies were retrieved from electronic databases and hand searches. After removing duplications, 519 were available; among them, 495 irrelevant citations were excluded with inclusion and exclusion criteria. Twenty-four citations were eligible for abstract screening, and fourteen citations were excluded including invitational studies, narrative reviews, animal studies, and studies that involved adults. Finally, studies for full texts were screened for eligibility for the research question, and then only five studies were available upon full-text phase analysis. The five studies involved 1740 children to evaluate the efficacy of Triphala and chlorhexidine mouthwashes in reducing gingivitis and dental plaque in children. Among them, one article showed low risk, three articles showed moderate risk, and one article showed high risk. Conclusion: While Triphala and chlorhexidine both reduce gingivitis, reports indicate that Triphala is less effective than chlorhexidine in improving plaque index scores. Further controlled studies are needed to confirm the effectiveness of Triphala mouthwash in children. Full article

Obesity, characterized by the excessive accumulation of fat, is a prevalent metabolic disorder that poses a significant global health concern. Triphala, an herbal combination consisting of Phyllanthus emblica Linn, Terminalia chebula Retz, and Terminalia bellerica (Gaertn) Roxb, has emerged as a potential solution for addressing concerns related to obesity. This study aimed to investigate the network pharmacology and molecular docking of Triphala to identify its bioactive ingredients and their interactions with pathways associated with obesity. The bioactive compounds present in Triphala and genes linked to obesity were identified, followed by an analysis of the protein-protein interaction networks. Enrichment analysis, including Gene Ontology analysis and Kyoto Encyclopedia of Genes and Genomes pathway analysis, was conducted. Prominent genes and compounds were selected for further investigation through molecular docking studies. The study revealed a close correlation between obesity and the AKT1 and PPARG genes. The observed binding energy between beta-sitosterol, 7-dehydrosigmasterol, peraksine, α-amyrin, luteolin, quercetin, kaempferol, ellagic acid, and phyllanthin with AKT1 and PPARG indicated a favorable binding affinity. In conclusion, nine compounds showed promise in regulating these genes for obesity prevention and management. Further research is required to validate their specific effects. Full article

The COVID-19 pandemic, caused by SARS-CoV-2, poses a significant global health threat. The spike glycoprotein S1 of the SARS-CoV-2 virus is known to induce the production of pro-inflammatory mediators, contributing to hyperinflammation in COVID-19 patients. Triphala, an ancient Ayurvedic remedy composed of dried fruits from three plant species—Emblica officinalis (Family Euphorbiaceae), Terminalia bellerica (Family Combretaceae), and Terminalia chebula (Family Combretaceae)—shows promise in addressing inflammation. However, the limited water solubility of its ethanolic extract impedes its bioavailability. In this study, we aimed to develop nanoparticles loaded with Triphala extract, termed “nanotriphala”, as a drug delivery system. Additionally, we investigated the in vitro anti-inflammatory properties of nanotriphala and its major compounds, namely gallic acid, chebulagic acid, and chebulinic acid, in lung epithelial cells (A549) induced by CoV2-SP. The nanotriphala formulation was prepared using the solvent displacement method. The encapsulation efficiency of Triphala in nanotriphala was determined to be 87.96 ± 2.60% based on total phenolic content. In terms of in vitro release, nanotriphala exhibited a biphasic release profile with zero-order kinetics over 0–8 h. A549 cells were treated with nanotriphala or its active compounds and then induced with 100 ng/mL of spike S1 subunit (CoV2-SP). The results demonstrate that chebulagic acid and chebulinic acid are the active compounds in nanotriphala, which significantly reduced cytokine release (IL-6, IL-1β, and IL-18) and suppressed the expression of inflammatory genes (IL-6, IL-1β, IL-18, and NLRP3) (p < 0.05). Mechanistically, nanotriphala and its active compounds notably attenuated the expression of inflammasome machinery proteins (NLRP3, ASC, and Caspase-1) (p < 0.05). In conclusion, the nanoparticle formulation of Triphala enhances its stability and exhibits anti-inflammatory properties against CoV2-SP-induction. This was achieved by suppressing inflammatory mediators and the NLRP3 inflammasome machinery. Thus, nanotriphala holds promise as a supportive preventive anti-inflammatory therapy for COVID-19-related chronic inflammation. Full article

In recent years, there has been growing scientific interest in the search for natural radioprotectors that can be used to mitigate the effects of radiation on patients, healthcare personnel, and even for space travel.

This review examines their composition, properties, and possible mechanisms of action in relation to their radioprotective properties. Exploring the ethnobotany of traditional Asian medicine is particularly interesting as it may lead to the discovery of new active compounds with radioprotective properties. Full article

Chebulic Myrobalan is the main ingredient in the Ayurvedic formulation Triphala, which is used for kidney and liver dysfunctions. Herein, natural nitrogen-doped carbon dots (NN-CDs) were prepared from the hydrothermal carbonization of Chebulic Myrobalan and were demonstrated to sense heavy metal ions in an aqueous medium. Briefly, the NN-CDs were developed from Chebulic Myrobalan by a single-step hydrothermal carbonization approach under a mild temperature (200 °C) without any capping and passivation agents. They were then thoroughly characterized to confirm their structural and optical properties. The resulting NN-CDs had small particles (average diameter: 2.5 ± 0.5 nm) with a narrow size distribution (1–4 nm) and a relatable degree of graphitization. They possessed bright and durable fluorescence with excitation-dependent emission behaviors. Further, the as-synthesized NN-CDs were a good fluorometric sensor for the detection of heavy metal ions in an aqueous medium. The NN-CDs showed sensitive and selective sensing platforms for Fe³⁺ ions; the detection limit was calculated to be 0.86 μM in the dynamic range of 5–25 μM of the ferric (Fe³⁺) ion concentration. Moreover, these NN-CDs could expand their application as a potential candidate for biomedical applications and offer a new method of hydrothermally carbonizing waste biomass. Full article

This study evaluated the in vitro and in vivo antiplasmodial efficacy and toxicity of aqueous and ethanolic extracts from traditional recipes used in Thailand. The aqueous and ethanolic extracts of ten traditional recipes were tested for in vitro antiplasmodial activity (parasite lactate dehydrogenase assay), cytotoxicity (MTT assay), and hemolysis). Oxidant levels were measured using cell-permeable probe 5-(and-6)-chloromethyl-2′,7′-dichlorodihydrofluorescein diacetate fluorescent dye-based assays. The best candidate was chosen for testing in mouse models using 4-day suppressive and acute toxicity assays. An in vitro study showed that ethanolic extracts and three aqueous extracts exhibited antiplasmodial activity, with an IC₅₀ in the range of 2.8–15.5 µg/mL. All extracts showed high CC₅₀ values, except for ethanolic extracts from Benjakul, Benjalotiga, and Trikatuk in HepG2 and Benjalotiga and aqueous extract from Chan-tang-ha in a Vero cell. Based on the results of the in vitro antiplasmodial activity, an aqueous extract of Triphala was chosen for testing in mouse models. The aqueous extract of Triphala exhibited good antiplasmodial activity, was safe at an oral dose of 2 g/kg, and is a potential candidate as a new source for the development of antimalarial drugs.

Background: The Indian Ayurvedic herbal formula Triphala (TPL) is known for its pharmacological properties for immunomodulation, anti-inflammation, antioxidant, and anti-cancer. This study aimed to investigate the acute and chronic toxicities of the Triphala recipe in a rat model. Methods: To assess the acute toxicities, 5000 mg/kg of TPL was orally administered to Sprague-Dawley rats. For chronic toxicities, different dose levels of TPL at 600, 1200, and 2400 mg/kg/day were given daily for 270 days. General health and behaviors and the body and organ weights of the rats were monitored. At the end of the experiment, blood samples were evaluated for hematology and biochemistry profiles. The evaluation of the internal organs’ appurtenance and necropsy was performed to confirm the tissue histopathology. Results: The results showed that there was no sign of acute toxicity in the TPL group with a decrease in sex organ weights. No significant differences in the rats’ behaviors, physical health, body, or organ weights were found between the controls and the rats receiving the 270/day of oral Triphala at 600, 1200, and 2400 mg/kg/day. However, some alterations in blood chemistries and hematology, including glucose, BUN, red blood cells, Hb, HCT, and MCV, were observed without abnormalities in histopathology. Conclusions: It has been demonstrated that the long-term use of TPL in rat models is safe. No toxic effects were found, suggesting possible safety for long-term use in humans. Full article

The objective of this study was to determine the effect of autochthonous Nepalese fruits on nutrient degradation, fermentation kinetics, total gas production, and methane production in in-vitro rumen fermentation. The fruits of Terminalia chebula (HA), Terminalia bellirica (BA), and Triphala churna (TC), a commercial mixture with equal parts (33.3% DM basis) of Phyllanthus emblica, Terminalia bellirica, and Terminalia chebula, were used. These were tested at three inclusion levels of 20% 40% and 100% of the total sample (as dry matter) in maize silage (MS). MS was used as a control (0% additive). These 10 treatments were tested for two 48-h incubations with quadruplicate samples using rumen fluid from 2 heifers. Total gas production (TGP: mL at standard temperature and pressure (STP)/g DM), methane production (expressed as % and mL/g DM), and volatile fatty acids were determined. After incubations, the filtrate was used to measure pH and volatile fatty acids (VFA), while the residue was used to measure degraded dry matter (dDM) and calculate the partitioning factor (PF48) and theoretical short-chain fatty acid concentration (tVFA). Rumen fluid pH linearly (p < 0.01) decreased in all treatments with increasing dose during fermentation. The CH₄% was less in all three treatments with 100% autochthonous plants than in control, but there were no significant linear or quadratic effects for increasing BA, HA, and TC doses. The PF48 increased for all treatments with a significant linear and quadratic effect (p < 0.05) of increasing dose. Compared to MS, the inclusion of autochthonous plants increased the total volatile fatty acids, with no significant dose effects. The tVFA linearly decreased (p > 0.05) with an increasing dose of BA and HA. All treatments showed quadratic effects on tVFA (p < 0.05) with increasing dose. Increasing TC dose linearly (p < 0.05) and quadratically (p < 0.05) increased total VFA, while increasing HA dose had only a quadratic (p < 0.05) effect on total VFA. All treatments reduced total gas production (TGP) and methane concentration (CH₄%) when compared to MS. The tested autochthonous fruits can be used as additives with a basal feed diet to reduce enteric methane emissions. The most effective anti-methanogenic treatment was 40% HA, which resulted in 18% methane reduction. Full article

As the human lifespan becomes longer, many people invest time and money in managing external beauty. However, managing external beauty has the disadvantage of causing side effects or that the effect does not last. Therefore, research and development are required to maximize effectiveness, eco-friendliness, and sustainably in beauty management. The purpose of this study was to experimentally identify the anti-aging effects, such as skin wrinkle and elasticity improvement, of extracts from Bahera, Phyllanthus emblica, Triphala, and Carica papaya, and to confirm their development as whitening and wrinkle functional cosmetic materials. In this study, a solid mixture was prepared using eco-friendly Terminalia bellirica, amla (Phyllanthus emblica), Triphala, and Carica papaya, and experimental samples were extracted. Antioxidant tests, antibacterial activity tests, polyphenol and flavonoid content, and deodorization tests were conducted to test the efficacy of experimental samples. The procedures and methods of these experiments are summarized in the following article. In this study, we found that the Bahera, Phyllanthus emblica, Triphala, and Carica papaya extracts had significant effects on whitening and wrinkle improvement, and that the effects of using ethanol-based extracts as the co-solvent were even greater. In other words, extracts of Bahera, Phyllanthus emblica, Triphala and Carica papaya showed antioxidant, whitening, and anti-wrinkle effects, and extracts that used ethanol as a co-solvent showed greater effects. In particular, we found that the optimal concentration of ethanol as a co-solvent maximizes its effectiveness at 70%. Full article

Traditional Triphala (three fruits), consisting of Phyllanthus emblica, Terminalia chebula, and Terminalia bellirica, presents a broad range of biological activities. However, its ability to inhibit dengue virus (DENV) infection has not been reported yet. Herein, the authors investigated the efficiency of three different Triphala formulations and its individual extract constituents to inhibit DENV infection. Treatment with T. bellirica extract or Triphala formulated with a high ratio of T. bellirica extract showed remarkable efficiency in significantly lowering DENV infection in Vero cells. Their effects were further studied in Huh7 cells, to address its potential ability in human cells. Treatment with 100 μg/mL of T. bellirica extract or Triphala resulted in an approximate 3000-fold or 1000-fold lowering of virus production, respectively. Furthermore, the treatment diminished IL-6 and CXCL-10 expressions, which are the hallmark of the cytokine storm phenomenon in DENV infection. The HPLC profiling demonstrated gallic acid as a major compound, the treatment by which showed its ability to effectively inhibit DENV infection after virus entry. Molecular docking demonstrated that gallic acid was able to interact with DENV NS5 protein, which could be one of Triphala’s antiviral mechanism. This study offers Triphala formulation and its ingredient, T. bellirica extract, as a natural based pharmaceutical to be used in DENV infection treatment. Full article

Background—Alzheimer’s disease (AD) is a multifactorial, progressive, neurodegenerative disease that is characterized by memory loss, personality changes, and a decline in cognitive function. While the exact cause of AD is still unclear, recent studies point to lifestyle, diet, environmental, and genetic factors as contributors to disease progression. The pharmaceutical approaches developed to date do not alter disease progression. More than two hundred promising drug candidates have failed clinical trials in the past decade, suggesting that the disease and its causes may be highly complex. Medicinal plants and herbal remedies are now gaining more interest as complementary and alternative interventions and are a valuable source for developing drug candidates for AD. Indeed, several scientific studies have described the use of various medicinal plants and their principal phytochemicals for the treatment of AD. This article reviews a subset of herbs for their anti-inflammatory, antioxidant, and cognitive-enhancing effects. Methods—This article systematically reviews recent studies that have investigated the role of neuroprotective herbs and their bioactive compounds for dementia associated with Alzheimer’s disease and pre-Alzheimer’s disease. PubMed Central, Scopus, and Google Scholar databases of articles were collected, and abstracts were reviewed for relevance to the subject matter. Conclusions—Medicinal plants have great potential as part of an overall program in the prevention and treatment of cognitive decline associated with AD. It is hoped that these medicinal plants can be used in drug discovery programs for identifying safe and efficacious small molecules for AD. Full article
