[Systematic review and Meta-analysis of efficacy and safety of Bidouyan Oral Liquid in treatment of rhinosinusitis].

This study aimed to systematically review the efficacy and safety of Bidouyan Oral Liquid in the treatment of rhinosinu-sitis(RS). CNKI, Wanfang, SinoMed, VIP, Cochrane Library, PubMed, EMbase, Web of Science, and Ovid were searched for the randomized controlled trial(RCT) of Bidouyan Oral Liquid for the treatment of RS patients. Moreover, the reference lists and the grey literature were searched manually. Two researchers independently screened the literature and extracted data. The Cochrane collaboration's tool for assessing risk of bias(RoB 2.0) in randomized trial was used to assess the methodological quality of the included stu-dies. Meta-analysis was performed in RevMan 5.3 and Stata 12.0, and the grades of recommendation, assessment, development and evaluation(GRADE) was employed to evaluate the quality of evidence. A total of 54 RCTs(35 with drug combinations and 19 with single drugs) comprising 7 511 patients(3 973 in the observation group and 3 538 in the control group) were included. Meta-analysis showed that Bidouyan Oral Liquid + conventional treatment was superior to conventional treatment alone in increasing the total response rate(RR=1.19, 95%CI[1.15, 1.24], P<0.000 01) and decreasing the Lund-Kennedy scores(MD=-1.94, 95%CI[-2.61,-1.26], P<0.000 01), Lund-Mackay scores(MD=-2.14, 95%CI[-2.98,-1.31], P<0.000 01), and visual analogue scale(VAS) scores(MD_(total VAS scores)=-1.28, 95%CI[-1.56,-1.01], P<0.000 01; MD_(nasal congestion VAS scores)=-0.58, 95%CI[-0.89,-0.27], P=0.000 2; MD_(runny nose VAS scores)=-0.61, 95%CI[-0.93,-0.29], P=0.000 2; MD_(olfactory dysfunction VAS scores)=-0.43, 95%CI[-0.52,-0.34], P<0.000 01; MD_(head and facial pain VAS scores)=-0.41, 95%CI[-0.57,-0.26], P<0.000 01). Furthermore, the combined treatment outperformed conventional treatment alone in improving the mucociliary transport rate(MTR)(MD=1.64, 95%CI[1.08, 2.20], P<0.000 01) and lowering the levels of inflammatory cytokines{tumor necrosis factor-α(TNF-α)(SMD=-1.95, 95%CI[-2.57,-1.33], P<0.000 01), interleukin-6(IL-6)(SMD=-2.64, 95%CI[-4.08,-1.21], P=0.000 3)} in RS patients. In addition, the combined treatment did not increase the incidence of adverse reactions(RR=0.83, 95%CI[0.44, 1.57], P=0.57). Bidouyan Oral Liquid was superior to conventional treatment in increasing total response rate(RR=1.25, 95%CI[1.18, 1.32], P<0.000 01), decreasing the Lund-Kennedy(P<0.01) and Lund-Mackay scores(P<0.05), alleviating major symptoms(P_(total VAS scores)<0.01; P_(nasal congestion VAS scores)<0.01; P_(runny nose VAS scores)<0.01; P_(olfactory dysfunction VAS scores)<0.05; P_(head and facial pain VAS scores)<0.01), and decreasing adverse reactions(P=0.03). The results showed that either Bidouyan Oral Liquid or Bidouyan Oral Liquid + conventional treatment can increase the total response rate, decrease the Lund-Kennedy and Lund-Mackay scores, and mitigate major symptoms. In addition, Bidouyan Oral Liquid + conventional treatment improved MTR and reduced the expression of TNF-α and IL-6 without causing serious adverse events. However, due to the limited methodological quality of the included studies, large-sample and high-quality RCTs are needed to provide evidence support.

Fish oil supplementation and risk of dementia among diabetic patients: a prospective study of 16,061 older patients.

BACKGROUND: Although n-3 Polyunsaturated fatty acids (PUFAs) may benefit cognitive performance, the association of n-3 PUFA intake with dementia risk under dysglycemia has not been examined. We aimed to evaluate the relationship between fish oil supplement use or fish consumption and dementia risk among older patients with diabetes. METHOD: A total of 16,061 diabetic patients aged over 60 years were followed up in the UK Biobank. Fish oil supplements use (yes or no) was collected by the touch screen questionnaire. The diagnosis of dementia was ascertained by the UK Biobank Outcome Adjudication Group. The hazard ratios (HRs) and 95% confidence intervals (95% CIs) were estimated using Cox proportional hazards models. RESULTS: A total of 337 cases of dementia were confirmed after a mean duration of 7.7 years (123,486 person-years) of follow-up. Habitual use of fish oil supplements showed a 24% lower dementia risk among older diabetic patients [HRs (95% CIs): 0.76 (0.60-0.98) (P = 0.031)] compared with non-users. Such inverse association was not modified by the APOE ε4 genotype. However, the consumption of both oily fish (≥2 times/week) and non-oily fish (≥2 times/week) had no significant association with dementia risk (p-trend = 0.271 and p-trend = 0.065) compared with non-consumers. CONCLUSION: In summary, fish oil supplementation may play a protective role in cognitive function across all APOE genotypes, while non-oily fish and oily fish consumption have no protective association among older diabetic patients.

Circulating fatty acids, genetic risk, and incident coronary artery disease: A prospective, longitudinal cohort study.

The role of fatty acids (FAs) in primary prevention of coronary artery disease (CAD) is highly debated, and the modification effect by genetic risk profiles remains unclear. Here, we report the prospective associations of circulating FAs and genetic predisposition with CAD development in 101,367 U.K. Biobank participants. A total of 3719 CAD cases occurred during a mean follow-up of 11.5 years. Plasma monounsaturated FAs (MUFAs) were positively associated with risk of CAD, whereas the risk was significantly lower with higher n-3 polyunsaturated FAs (PUFAs) and more reductions in risk were detected among TT carriers of rs174547. Furthermore, increased plasma saturated FAs (SFAs) and linoleic acid were related to a significant increase in CAD risk among participants with high genetic risk (genetic risk score > 90%). These findings suggest that individuals with high genetic risk need to reduce plasma SFAs levels for CAD prevention. Supplementation of n-3 PUFAs for CAD prevention may consider individuals' genetic makeup.

Association of Fish Oil Supplementation with Risk of Coronary Heart Disease in Individuals with Diabetes and Prediabetes: A Prospective Study in the UK Biobank.

This study aimed to explore the association between habitual intake of fish oil supplementation and the risk of developing CHD in patients with prediabetes and diabetes. Habitual use of fish oil was assessed by repeated questionnaires. Cox proportional hazard models were applied to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). Over a median follow-up of 11.6 years, 4304 and 3294 CHD cases were documented among 47,663 individuals with prediabetes and 22,146 patients with diabetes in the UK Biobank, respectively. After multivariable adjustment, the HRs (95% CI) of CHD were 0.91 (0.85-0.98) and 0.87 (0.80-0.95) for individuals utilizing fish oil supplementation compared with non-users among the participants with prediabetes and diabetes, respectively. Furthermore, we identified an inverse relationship between fish oil use and CHD incidence, which was significantly mediated by serum C-reactive protein (CRP) levels in individuals with prediabetes and by very-low-density lipoprotein cholesterol (VLDL-C) in patients with diabetes at baseline. The inverse associations were consistent in the analyses stratified by potential confounders. In conclusion, the consumption of fish oil supplements was linked to decreased serum CRP and VLDL-C levels and subsequent CHD risk among adults with prediabetes and diabetes. Our findings highlight the important role of the habitual intake of fish oil supplements in preventing CHD in individuals with impaired glucose metabolism.

Ginseng-Containing Sijunzi Decoction Ameliorates Ulcerative Colitis by Orchestrating Gut Homeostasis in Microbial Modulation and Intestinal Barrier Integrity.

Ulcerative colitis (UC) has become a global epidemic, and the lack of an effective cure highlights the necessity and urgency to explore novel therapies. Sijunzi Decoction (SJZD), a classical Chinese herbal formula, has been comprehensively applied and clinically proven effective in treating UC; however, the pharmacological mechanism behind its therapeutic benefits is largely obscure. Here, we find that SJZD can restore microbiota homeostasis and intestinal barrier integrity in DSS-induced colitis. SJZD significantly alleviated the colonic tissue damage and improved the goblet cell count, MUC2 secretion, and tight junction protein expressions, which indicated enhanced intestinal barrier integrity. SJZD remarkedly suppressed the abundance of phylum Proteobacteria and genus Escherichia-Shigella, which are typical features of microbial dysbiosis. Escherichia-Shigella was negatively correlated with body weight and colon length, and positively correlated with disease activity index and IL-1[Formula: see text]. Furthermore, through gut microbiota depletion, we confirmed that SJZD exerted anti-inflammatory activities in a gut microbiota-dependent manner, and fecal microbiota transplantation (FMT) validated the mediating role of gut microbiota in the SJZD treatment of UC. Through gut microbiota, SJZD modulates the biosynthesis of bile acids (BAs), especially tauroursodeoxycholic acid (TUDCA), which has been identified as the signature BA during SJZD treatment. Cumulatively, our findings disclose that SJZD attenuates UC via orchestrating gut homeostasis in microbial modulation and intestinal barrier integrity, thus offering a promising alternative approach to the clinical management of UC.

Simultaneous recovery of short-chain fatty acids and phosphorus during lipid-rich anaerobic fermentation with sodium hydroxide conditioning.

Anaerobic fermentation (AF) could achieve simultaneous recovery of short-chain fatty acids (SCFAs) and phosphorus (P) when waste activated sludge (WAS) and meat processing waste (MPW) act as co-substrate. However, long-chain fatty acids, the degradation intermediates of lipids, always inhibit anaerobic microbial activity. Therefore, sodium hydroxide (NaOH) conditioning was applied to improve the lipid-rich AF performance in this study. The results demonstrated that 96% WAS (v/v) with NaOH addition that remaining at pH 7.5 could achieve the maximum SCFAs yield (1180.05 mg/g VSfed) at 12 d, and ortho-P content in the AF liquor (AFL) was much more than that of without NaOH addition. Anaerovibrio and Aminobacterium, one kind of lipolytic and proteolytic bacteria, respectively, became the major genus in the lipid-rich AF system. 86% of P in the AFL from 96% WAS + pH 7.5 reactor was recovered through vivianite crystallization method, with 91% of SCFAs remaining in the post-AFL. Meanwhile, analysis results verified vivianite formation in the P precipitate products. Overall, this study provided a new idea to achieve SCFAs and P simultaneous recovery from WAS and MPW through AF with NaOH conditioning and vivianite crystallization.

Layered double hydroxides for phosphorus recovery from lipid-rich waste anaerobic fermentation liquor.

This study aimed to extract orthophosphate (ortho-P) from lipid-rich waste AF liquor (AFL) by Mg/Al layered double hydroxides (Mg/Al LDHs) adsorption, evaluate the influence of carbonate and investigate adsorption mechanisms. The carbonate influence experiment using synthetic P-rich wastewater indicated that low carbonate level was favorable for P extraction by LDHs. And then, real AFL rich in volatile fatty acids (VFAs), carbonate and ortho-P was applied as adsorbate to explore the Mg/Al LDHs adsorption performance. Experimental results indicated that 4 g/L Mg/Al LDHs could extract 88.3% of ortho-P from the AFL with low carbonate level (4829.83 mg CaCO3/L), and the adsorption quantity was 62.99 mg P/g LDHs, however, negligible VFAs were extracted. Kinetics and mechanisms analysis indicated that adsorption of P onto Mg/Al LDHs was a rapid physiochemical process, including ion exchange and surface adsorption. Finally, the nutrients release test confirmed the slow-release property of intercalated P.

Lifelong docosahexaenoic acid intervention ameliorates aging in the telomere-DNA-mitochondria axis in telomerase-deficient mice.

The health benefits of n-3 polyunsaturated fatty acids (PUFAs) in multiple age-related diseases are associated with telomere length. Telomerase is intimately related to inflammation and oxidative stress, but whether the underlying function of n-3 PUFAs on telomere maintenance is based on telomerase activation or related mechanisms remains unclear. Herein, we utilized late-generation (G4) telomerase-deficient (Terc-/-) mice to perform a lifelong docosahexaenoic acid (DHA) intervention to determine the potential of DHA in telomere maintenance and health promotion. Unfortunately, DHA failed to prolong mouse longevity in either intrinsic or premature aging. However, intriguingly, lifelong dietary DHA intervention slowed the aging phenotypes and profoundly attenuated telomere attrition in blood leukocytes and multiple tissues, consistent with decreased ß-galactosidase activity and other senescence hallmarks with no observed sex differences. Notably, DHA intervention alleviated telomere attrition-induced γ-H2AX accumulation dependent on poly (ADP-ribose) polymerase 1 (PARP1) recruitment, and further regulated mitochondrial dysfunction critically involved in the DNA damage response. Together with the improvement of mitochondria function, the blocked reactive oxygen species (ROS) accumulation and suppression of the nuclear factor-κB (NF-κB)/nucleotide-binding domain-like receptor protein 3 (NLRP3)/caspase-1 pathways partially indicated anti-oxidative and anti-inflammatory effects of DHA. These data revealed a regulatory paradigm involving DHA in the telomere-DNA-mitochondria feedback loop mediated by DNA damage response and inflammation in alleviating senescence, which may hold potential as a translatable intervention in telomere-related diseases during aging.

The relationship between n-3 polyunsaturated fatty acids and telomere: A review on proposed nutritional treatment against metabolic syndrome and potential signaling pathways.

Metabolic syndrome (MetS), a cluster of metabolic abnormalities composed of central obesity, elevated blood pressure, glucose disturbances, hypercholesterolemia and dyslipidaemia, has increasingly become a public health problem in the 21st century worldwide. The dysfunction of telomeres, the repetitive DNA with highly conserved sequences (5'-TTAGGG-3'), is remarkably correlated with organismal aging, even suggesting a causal relationship with metabolic disorders. The health benefits of n-3 polyunsaturated fatty acids (PUFAs) in multiple disorders are associated with telomere length in evidence, which have recently drawn wide attention. However, functional targets and pathways for the associations of n-3 PUFAs and telomere with MetS remain scare. Few studies have summarized the role of n-3 PUFAs in DNA damage repair pathways, anti-inflammatory pathways, and redox balance, linking with telomere biology, and other potential telomere-related signaling pathways. This review aims to (i) elucidate how n-3 PUFAs ameliorate telomere attrition in the context of anti-oxidation and anti-inflammation; (ii) unravel the role of n-3 PUFAs in modulating telomere-related neuron dysfunction and regulating the neuro-endocrine-immunological network in MetS; (iii) epidemiologically implicate the associations of metabolic disorders and n-3 PUFAs with telomere length; and (iv) suggest promising biochemical approaches and advancing methodologies to overcome the inter-variation problem helpful for future research.

Self-Assembling Anchorage of Hyaluronic Acid on the Nanoparticle Surface Confers Superiority of Triple Negative Breast Cancer Treatment.

Triple-negative breast cancer (TNBC) has been listed as one of the most fatal diseases, and no effective targeting treatment is clinically available. Although CD44-targeting hyaluronic acid (HA) has been utilized as targeting ligands in many studies, no facile ways have been developed through HA self-assembly at the nanoparticle surface. Herein, we reported N-isopropylacrylamide-grafted chitosan-based nanoparticles self-assembling with HA (HA-NPs) through electrostatic forces and loaded with curcumin (CUR). The HA-NPs displayed pH-responsive properties due to the chemical modification of chitosan, and the preparation process was optimized by central composite design-response surface methodology. HA anchorage confers the vehicle with tumor-targeting capability. HA-NPs displayed more robust effects of inhibiting TNBC primary tumor growth than free CUR and a plain counterpart but without increased systemic cytotoxicity. In addition, in vivo pharmacokinetic studies showed that HA-NPs significantly increased the in vivo residence time of free CUR and improved the bioavailability of CUR. These findings suggested that chitosan-based HA-NPs may provide a feasible and unique strategy to achieve CD44 targeting and enhance its efficacy in vivo for the treatment of advanced TNBC.

Metabolomic profiling and alleviation of oxidative stress of Huangjing Zanyu capsule treating oligoasthenospermia.

Background: The traditional Chinese medicine (TCM) patent medicine Huangjing Zanyu capsule (HJZY capsule) has achieved satisfactory clinical effects in the treatment of oligoasthenospermia (OAS). This study aimed to elucidate the impact of HJZY capsule on the reproductive system, focusing on oxidative stress and metabolism profiling during the intervention, to clarify the therapeutic mechanism of HJZY capsule in treating OAS. Methods: Cyclophosphamide was used to establish OAS model rats. Time-sequence specimen collection was applied to monitor the dynamic development of the pharmacological effect of HJZY capsule. Superoxide dismutase (SOD), glutathione peroxidase (GPX), and malonaldehyde (MDA) were evaluated by biochemistry kits to examine the impact of HJZY capsule on oxidative stress. Non-targeted metabolomics was conducted for urine and testis samples, respectively, to investigate metabolic pathways through which the HJZY capsule takes effect. Results: The HJZY capsule elevated sperm density from 62.1±8.28, passing 68.4±7.52, to 75.9±8.48×106/mL, and sperm motility from 62.0%±3.94%, passing 70.8%±9.72%, to 68.8%±4.37%. Meanwhile, SOD (P<0.05 in week 2) and GPX activity levels of HJZY groups were elevated to a certain degree, respectively, and lipid oxidation was attenuated, as shown by decreased MDA content (P<0.05 in week 2). Metabolomics results showed that the HJZY capsule could modulate pathways including taurine metabolism, purine and pyrimidine metabolism, glycerolipid and glycerophospholipid metabolism, and multiple amino acid metabolisms, among others. The cluster analysis results showed that urinary and testicular metabolomics differed in the strength of discrimination between rats in the OAS model and the HJZY groups. Conclusions: The HJZY capsule exerts a comprehensive effect on OAS through influencing various metabolic pathways. Non-targeted metabolomics provides an effective way for profiling complex TCM prescriptions.

Chemical profiling of root bark extract from Oplopanax elatus and its in vitro biotransformation by human intestinal microbiota.

Oplopanax elatus (Nakai) Nakai, in the Araliaceae family, has been used in traditional Chinese medicine (TCM) to treat diseases as an adaptogen for thousands of years. This study established an ultra-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (UPLC-Q-TOF/MS) method to identify chemical components and biotransformation metabolites of root bark extract from O. elatus. A total of 18 compounds were characterized in O. elatus extract, and 62 metabolites by human intestinal microbiota were detected. Two polyynes, falcarindiol and oplopandiol were recognized as the main components of O. elatus, whose metabolites are further illustrated. Several metabolic pathways were proposed to generate the detected metabolites, including methylation, hydrogenation, demethylation, dehydroxylation, and hydroxylation. These findings indicated that intestinal microbiota might play an essential role in mediating the bioactivity of O. elatus.

Eicosapentaenoic and docosahexaenoic acids attenuate hyperglycemia through the microbiome-gut-organs axis in db/db mice.

BACKGROUND: Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been suggested to prevent the development of metabolic disorders. However, their individual role in treating hyperglycemia and the mechanism of action regarding gut microbiome and metabolome in the context of diabetes remain unclear. RESULTS: Supplementation of DHA and EPA attenuated hyperglycemia and insulin resistance without changing body weight in db/db mice while the ameliorative effect appeared to be more pronounced for EPA. DHA/EPA supplementation reduced the abundance of the lipopolysaccharide-containing Enterobacteriaceae whereas elevated the family Coriobacteriaceae negatively correlated with glutamate level, genera Barnesiella and Clostridium XlVa associated with bile acids production, beneficial Bifidobacterium and Lactobacillus, and SCFA-producing species. The gut microbiome alterations co-occurred with the shifts in the metabolome, including glutamate, bile acids, propionic/butyric acid, and lipopolysaccharide, which subsequently relieved ß cell apoptosis, suppressed hepatic gluconeogenesis, and promoted GLP-1 secretion, white adipose beiging, and insulin signaling. All these changes appeared to be more evident for EPA. Furthermore, transplantation with DHA/EPA-mediated gut microbiota mimicked the ameliorative effect of DHA/EPA on glucose homeostasis in db/db mice, together with similar changes in gut metabolites. In vitro, DHA/EPA treatment directly inhibited the growth of Escherichia coli (Family Enterobacteriaceae) while promoted Coriobacterium glomerans (Family Coriobacteriaceae), demonstrating a causal effect of DHA/EPA on featured gut microbiota. CONCLUSIONS: DHA and EPA dramatically attenuated hyperglycemia and insulin resistance in db/db mice, which was mediated by alterations in gut microbiome and metabolites linking gut to adipose, liver and pancreas. These findings shed light into the gut-organs axis as a promising target for restoring glucose homeostasis and also suggest a better therapeutic effect of EPA for treating diabetes. Video abstract.

Flavor of rapeseed oil: An overview of odorants, analytical techniques, and impact of treatment.

As one of the three major vegetable oils in the world, rapeseed oil is appreciated for its high nutritional value and characteristic flavor. Flavor is an essential attribute, determining rapeseed oil quality and consumer acceptance. The present manuscript provides a systematic literature review of recent advances and knowledge on the flavor of rapeseed oil, which focuses on aroma-active as well as off-flavor compounds, flavor analysis techniques (i.e., extraction, qualitative, quantitative, sensory, and chemometric methods), and effects of treatments (storage, dehulling, roasting, microwave, flavoring with herbs, refining, and oil heating) on flavor from sensory and molecular perspectives. One hundred thirty-seven odorants found in rapeseed oil from literature are listed and possible formation pathways of some key aroma-active compounds are also proposed. Future flavor analysis techniques will evolve toward time-saving, portability, real-time monitoring, and visualization, which aims to obtain a "complete" flavor profile of rapeseed oil. The changes of volatile compounds in rapeseed oil under different treatments are summarized in this view. Studies to elucidate the influence of different treatments on the formation of aroma-active compounds are needed to get a deeper understanding of factors leading to the variations of rapeseed oil flavor.

Chinese Propolis Prevents Obesity and Metabolism Syndromes Induced by a High Fat Diet and Accompanied by an Altered Gut Microbiota Structure in Mice.

The increasing incidence of obesity poses a great threat to public health worldwide. Recent reports also indicate the relevance of obesity in metabolic diseases. Chinese propolis (CP), as a well-studied natural nutraceutical, has shown a beneficial effect on alleviating diabetes mellitus. However, few studies have investigated the effect of CP on weight management and energy balance. We examined the beneficial effects of dietary CP on weight in high-fat diet-fed female and male mice and determined whether CP alters gut microbiota. In this study, dietary CP supplementation reduces body weight and improves insulin resistance in high-fat diet (HFD)-fed mice in a dose-dependent manner. CP treatment also reverses liver weight loss and triglyceride accumulation in association with hepatic steatosis. The 16S rRNA analysis of gut microbiota demonstrated that CP treatment modulates the composition in HFD-fed mice. Our study also suggests that male mice were more sensitive to CP treatment than female mice. Taken together, CP supplementation reduces weight gain and reverses gut microbiome dysbiosis induced by HFD. Further, the effects of CP treatment on metabolic biomarkers and microbiome structure differ by gender.

Revealing the Synergistic Mechanism of Multiple Components in Compound Fengshiding Capsule for Rheumatoid Arthritis Therapeutics by Network Pharmacology.

BACKGROUND: Compound Fengshiding capsule (CFC), is a Chinese formulation from herbal origin including Alangium platanifolium, Angelicae dahurica, Cynanchum paniculatum and Glycyrrhiza uralensis. CFC is widely used as clinical therapy against rheumatoid arthritis. However, its exact mechanism of action has not been explored yet. METHODS: In order to explore the synergistic mechanism of CFC, we designed a study adopting network pharmacology scheme to screen the action targets in relation to the CFC components. The study analyses target facts of salicin, paeonol, liquiritin and imperatorin from PubMed database, and explores the potential pharmacological targets of rheumatoid arthritis, cervical neuralgia and sciatica related diseases for their interaction. RESULTS: The results of boosted metabolic pathway showed that the chemical components of CFC interrupted many immune-related pathways, thus participating in immunity regulation of the body and playing a role in the treatment of rheumatism. Collectively, CFC has apoptotic, oxidative stress modulatory and anti-inflammatory effects that accumulatively serve for its clinical application against rheumatoid arthritis. CONCLUSION: Conclusively, our findings from present study reconnoiters and compacts systematic theoretical approach by utilizing the network pharmacology mechanism of four effective components for the treatment of rheumatism indicating sufficient potential drug targets associated with CFC against rheumatism. These interesting findings entreaties for further in vitro and in vivo studies on the mechanism of compound active ingredient against rheumatism.
