Protective Effect of Modified Ginseng Baidu Powder Prophylactic Administration on LPS-Induced Acute Respiratory Distress Syndrome in Mice.

Severe Corona Virus Disease 2019 (COVID-19) patients may develop acute respiratory distress syndrome (ARDS). Modified Ginseng Baidu Powder (referred to as Baidu Powder) was used for respiratory system diseases caused by colds. To study the effect of Baidu Powder on protecting ARDS mice model and its underlying active ingredients and targets intervening in COVID-19. The optimal LPS concentration was selected for the induction of mouse ARDS model, and the protective effect of Baidu Powder prophylactic administration on LPS-induced ARDS mouse models was explored by mouse survival time analysis, lung wet/dry weight (W/D) ratio, pathological staining, and inflammatory factor detection. On the basis of pharmacodynamics, the network pharmacological analysis was used for target prediction for future mechanism study. 5 mg/kg LPS was selected for the construction of a mouse ARDS model, based on a mortality rate of 87% and the lung W/D ratio of 5.29 ± 0.23. Prophylactic administration of Baidu Powder at 125 g/L significantly reduced death, lung damage, inflammatory cell infiltration, and cytokine production (TNF-α, IL-6, and IL-10) caused by LPS-induced ARDS. The results of network pharmacological analysis showed that 42 target genes of Baidu Powder intervening in COVID-19 were involved in 30 biological processes related to COVID-19 and inflammation, and 11 signaling pathways related to lung diseases or inflammation. 5 mg/kg LPS can successfully establish a mice ARDS disease model; 125 g/L Baidu Powder prophylactic administration does not have toxicity and has a certain effect on protecting ARDS mouse models induced by LPS. Baidu Powder may intervene COVID-19-induced ARDS through multiple targets.

Untargeted Metabolomics and Soil Community Metagenomics Analyses Combined with Machine Learning Evaluation Uncover Geographic Differences in Ginseng from Different Locations.

Panax ginseng C.A. Meyer, known as the "King of Herbs," has been used as a nutritional supplement for both food and medicine with the functions of relieving fatigue and improving immunity for thousands of years in China. In agricultural planting, soil environments of different geographical origins lead to obvious differences in the quality of ginseng, but the potential mechanism of the differences remains unclear. In this study, 20 key differential metabolites, including ginsenoside Rb1, glucose 6-phosphate, etc., were found in ginseng from 10 locations in China using an ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-QTOF-MS)-untargeted metabolomics approach. The soil properties were analyzed and combined with metagenomics technology to explore the possible relationships among microbial elements in planting soil. Through Spearman correlation analysis, it was found that the top 10 microbial colonies with the highest abundance in the soil were significantly correlated with key metabolites. In addition, the relationship model established by the random forest algorithm and the quantitative relationship between soil microbial abundance and ginseng metabolites were successfully predicted. The XGboost model was used to determine 20(R)-ginseng Rg2 and 2'(R)-ginseng Rg3 as feature labeled metabolites, and the optimal ginseng production area was discovered. These results prove that the accumulation of metabolites in ginseng was influenced by microorganisms in the planting soil, which led to geographical differences in ginseng quality.

Effect of ginseng stem leaf extract on the production performance, meat quality, antioxidant status, immune function, and lipid metabolism of broilers.

Introduction: The present study explores the effect of ginseng stem leaf (GSL) extract on the production performance, meat quality, antioxidant status, immune function, and lipid metabolism of white feathered broilers. Methods: There were 6 replicates in each group, with 10 broilers in each replicate. In the 42 day trial, 300 AA broilers were randomly divided into five groups: control group (CON), 1.25% GSL extract group (GSL-L), 2.5% GSL group (GSL-M), 5% GSL group (GSL-H), and 45 mg/kg chlortetracycline group (CTC). Results: The results showed that different doses of GSL extract could improve the body weight, feed to gain ratio (F/G), average daily feed intake (ADFI), average daily gain (ADG), and meat quality of broilers. Compared with the control group, the addition of different doses of GSL improved the antioxidant and immune abilities of broilers to varying degrees, and the effect of GSL extract was significant in the GSL-H group (p < 0.05). In addition, medium and high doses of GSL extract significantly reduced the blood triglyceride (TG) and total cholesterol (TC) contents of broilers (p < 0.05). Discussion: Adding GSL extract to the feed has a positive impact on the body weight, meat quality, antioxidant capacity, immunity, and blood lipids of broilers.

Effects of soil properties and microbial community composition on ginsenosides accumulation in farmland ginseng.

Soil is the material basis of ginseng survival, and revealing the correlation between soil and ginsenoside has far-reaching significance for the sustainable development of ginseng industry. In this study, the content of ginsenosides in 3-year-old ginseng roots, the physicochemical properties of rhizosphere soil and the microbial community composition were studied. The results showed that the contents of total saponins in different months were significantly different. The richness and diversity of soil microbial community decreased with the extension of planting time. The activities of complexed iron, organic matter and protease in soil had significant effects on α-diversity of soil microbial community. Functional gene analysis showed that carbon sequestration, protein translation, nitrogen metabolism, transcription factors and chlorophyll metabolism were the main functions of soil bacterial community. The results of correlation analysis and redundancy analysis showed that pH, available potassium, organic matter, complexed iron, Firmicutes and Acidobacteria were the key factors affecting ginsenoside accumulation. The changes of soil physical and chemical properties affect the abundance of soil microorganism, and the accumulation of ginsenoside in ginseng is affected by soil microorganism. A co-regulatory network of Physicochemical Properties-Microbe-Ginsenoside was established. To provide theoretical support for the cultivation of ginseng.

Panax ginseng extract prevents UVB-induced skin photodamage by modulating VMP1-mediated ER stress.

BACKGROUND: The endoplasmic reticulum (ER) stress is a crucial toxic signaling event triggered by chronic exposure to Ultraviolet B radiation (UVB), which significantly exacerbate photodamage responses in the irradiated skin. Therefore, the identification of agents capable of inhibiting ER stress could serve as a promising therapeutic strategy for addressing the unmet clinical needs in the treatment of UVB-induced photodamage. METHODS: A UVB-irradiated mouse model was used and topical administration of Panax ginseng extract was carried out for a duration of 9 weeks. Vitamin E was used as a positive control. After 9 weeks of administration, the skin appearance, epidermal hyperplasia, infiltration of inflammatory cells, apoptosis, and collagen content were measured. The keratinocytes were irradiated with 6 mJ/cm2 UVB to establish an in vitro model. The levels of ER stress and apoptosis were investigated both in vivo and in vitro using qRT-PCR, immunoblotting, and immunofluorescence. RESULTS: Among the 14 extracts derived from 13 distinct plant species that were screened, Panax ginseng, Prunus mume, and Camellia japonica showed inhibitory effect on UVB-induced ER stress. Notably, Panax ginseng effectively inhibits collagen degradation and apoptosis in both irradiated keratinocytes and Balb/C mice skin. Furthermore, the silencing of VMP1 significantly impeded the cellular protective effect of Panax ginseng extract on UVB-irradiated keratinocytes, indicating that Panax ginseng exerts its protective effects through targeted promotion of VMP1. CONCLUSION: Our data suggest that Panax ginseng extract possess a therapeutical effect on UVB radiation-induced photodamage by promoting VMP1-mediated inhibition of ER stress.

Recent advances in nano and micro formulations of Ginsenoside to enhance their therapeutic efficacy.

BACKGROUND AND AIMS: Ginsenosides, the main component of Panax ginseng, have long been recognized for their therapeutic benefits and are thought to have neuroprotective, antidiabetic, anti-depressant, antioxidant, anti-cancer, and anti-stress properties. However, due to their low water solubility, low biomembrane permeability, gastrointestinal dysfunction, and total metabolism in the body, ginsenosides have a poor absorption profile that has hindered the therapeutic potential of these organic molecules. METHODS: Initially, we broadly illuminated the several techniques of extraction of Ginsenosides using Panax quinquefolius and Panax ginseng. Subsequently, we focused on different delivery methods to improve the stability, permeability, and solubility of natural chemicals, which raises the bioavailability of ginsenoside. Lastly, we explained significance of a variety of nano and microscale delivery systems, including liposomes, ethosomes, transfersomes, metal/metal oxide systems, micro/nanoemulsions, polymeric micro/nanoparticles (NPs), liposomes, transfersomes, and micelles to increase the bioavailability of ginsenosides. RESULTS: The utilization of micro/nanoscale delivery methods, such as liposome-based delivery, polymer micro/nanoparticle distribution, and micro/nanoemulsion, to increase the bioavailability of ginsenosides has recently advanced, and we have emphasized these advances in this study. Furthermore, the disadvantages of ginsenosides were also discussed, including the challenges associated with putting these delivery systems into practice in clinical settings and suggestions for further research. CONCLUSION: In summary, ginsenosides-based administration has several benefits that make it a potentially useful substance for a range of therapeutic purposes.

Exploring the molecular mechanism of ginseng against anthracycline-induced cardiotoxicity based on network pharmacology, molecular docking and molecular dynamics simulation.

BACKGROUND: Previous clinical and basic studies have revealed that ginseng might have cardioprotective properties against anthracycline-induced cardiotoxicity (AIC). However, the underlying mechanism of ginseng action against AIC remains insufficiently understood. The aim of this study was to explore the related targets and pathways of ginseng against AIC using network pharmacology, molecular docking, cellular thermal shift assay (CETSA) and molecular dynamics (MD) simulations. RESULTS: Fourteen drug-disease common targets were identified. Enrichment analysis showed that the AGE-RAGE in diabetic complications, fluid shear stress and atherosclerosis, and TNF signaling pathway were potentially involved in the action of ginseng against AIC. Molecular docking demonstrated that the core components including Kaempferol, beta-Sitosterol, and Fumarine had notable binding activity with the three core targets CCNA2, STAT1, and ICAM1. Furthermore, the stable complex of STAT1 and Kaempferol with favorable affinity was further confirmed by CETSA and MD simulation. CONCLUSIONS: This study suggested that ginseng might exert their protective effects against AIC through the derived effector compounds beta-Sitosterol, Kaempferol and Fumarine by targeting CCNA2, STAT1, and ICAM1, and modulating AGE-RAGE in diabetic complications, fluid shear stress and atherosclerosis, and TNF signaling pathways.

Korean Red Ginseng Extract Powder Mitigates Fasting And Postprandial Hyperglycemia in Type 2 Diabetic Mice.

Type 2 diabetes mellitus (T2DM) involves insulin resistance and elevated blood sugar levels, causing complications. Red ginseng extract powder (RGEP) from Panax ginseng Meyer shows promise for diabetes treatment. However, its efficacy in managing T2DM remains unclear. Therefore, this study aims to evaluate the effectiveness of RGEP in a mouse model of T2DM. The efficacy of RGEP in treating T2DM was assessed in db/db mice. Mice were divided into seven groups: control, db/db, metformin, and RGEP at 50, 100, 200, and 400 mg/kg. Administered orally for 9 weeks, RGEP effects on glucose regulation and insulin sensitivity were assessed through various metabolic parameters. In addition, mRNA expression levels of genes associated with hepatic gluconeogenesis and insulin sensitivity were examined. Fasting blood sugar showed a significant decrease in all RGEP concentration groups, but OGTT and insulin tolerance test showed a significant decrease at the RGEP concentration of 400 mg/kg, indicating enhanced glycemic control. Moreover, RGEP dose-dependently decreased serum glucose, HbA1c levels, and homeostatic model assessment of insulin resistance values, suggesting its effectiveness in reducing insulin resistance in db/db mice. Furthermore, RGEP downregulated mRNA expression of key components in the gluconeogenesis pathway (G6Pase, FOXO1, GLUT4, and PEPCK), insulin sensitivity (leptin, insulin1, PTP1B, GLP-1, and DPP-4), and mitochondria energy metabolism (PGC1) in either the liver or pancreas, while simultaneously upregulating GLP-1 expression. In conclusion, these findings highlight the potential of RGEP as a complementary therapy for T2DM, indicating therapeutic efficacy in managing diabetic complications through improved metabolic parameters.

Study based on metabolomics and network pharmacology to explore the mechanism of Ginseng-Douch compound fermentation products in the treatment of hyperlipidemia.

BACKGROUND: Ginseng-Douchi (GD) is a complex fermented product of ginseng and soybean, similar to natto, and is effective in the treatment of hyperlipidemia, but the mechanism of action involved needs to be further explored. RESULTS: The present study combines a comprehensive strategy of network pharmacology and metabolomics to explore the lipid-lowering mechanism of GD. First, a hyperlipidemia rats model induced by a high-fat diet was established to evaluate the therapeutic effects of GD. Second, potential biomarkers were identified using serum metabolomics and metabolic pathway analysis was performed with MetaboAnalyst. Third, network pharmacology is used to find potential therapeutic targets based on the blood-influencing components of GD. Finally, core targets were obtained through a target-metabolite and the enrichment analysis of biomarkers-genes. Biochemistry analysis showed that GD exerted hypolipidemic effects on hyperlipidemic rats. Nineteen potential biomarkers for the GD treatment of hyperlipidemia were identified by metabolomics, which was mainly involved in linoleic acid metabolism, glycerophospholipid metabolism, ether lipid metabolism, alpha-linolenic acid metabolism and glycosylphosphatidylinositol-anchor biosynthesis. GD had a callback function for ether lipid metabolism and glycerophospholipid metabolism pathways. Eighteen blood components were identified in serum, associated with 85 potential therapeutic targets. The joint analysis showed that three core therapeutic targets were regulated by GD, including PIK3CA, AKT1 and EGFR. CONCLUSION: This study combines serum medicinal chemistry of traditional Chinese medicine, network pharmacology and metabolomics to reveal the regulatory mechanism of GD on hyperlipidemia. © 2024 Society of Chemical Industry.

The Cameroon Kabir chicken has several production traits which makes it desirable by many farmers and hobbyists. This study was aimed at evaluating the potential of P. ginseng as a feed additive in the diet of Cameroon kabir hens reared under intensive conditions. A total of 84 kabir chickens were weighed and assigned to four dietary treatments. The birds in T0 were fed the control diet (0 % PGRM), while those in T1, T2, T3, were fed diets containing 0.5, 0.75 and 1 % PGRM respectively. The results showed that there was a significant difference (p < 0.05) in the egg lay, egg mass and hen-day egg production of the birds between the 0.5 % and 0.75 % PGRM groups. The 0.75 % PGRM group recorded the highest mean egg weight, and it was significantly (p < 0.05) different from the other PGRM groups, but similar (p > 0.05) to the control. There was also a significant difference (p < 0.05) in the hatchability percent between the 0.5 % and 0.75 % treatments groups, with the 0.5 % group recording the highest hatchability percent of 65.14 %, and the 0.75 % group recording the least hatchability percent of 12.94 %. Results for the chick hatching weights showed significant differences (p < 0.05) between the 0.75 % PGRM group and the control. In conclusion, P. ginseng as a feed additive in the diet of Cameroon kabir hens at 0.5 % improved their reproductive performance, and also improved the survivability of their offspring better but not in the number of eggs laid by chicks.

Low methyl-esterified ginseng homogalacturonan pectins promote longevity of Caenorhabditis elegans via impairing insulin/IGF-1 signalling.

Panax ginseng C. A. Meyer (ginseng) is a medicinal plant widely used for promoting longevity. Recently, homogalacturonan (HG) domain-rich pectins purified from some plants have been reported to have anti-aging-related activities, leading us to explore the longevity-promoting activity of the HG pectins from ginseng. In this study, we discovered that two of low methyl-esterified ginseng HG pectins (named as WGPA-2-HG and WGPA-3-HG), whose degree of methyl-esterification (DM) was 16 % and 8 % respectively, promoted longevity in Caenorhabditis elegans. Results showed that WGPA-2-HG/WGPA-3-HG impaired insulin/insulin-like growth factor 1 (IGF-1) signalling (IIS) pathway, thereby increasing the nuclear accumulation of transcription factors SKN-1/Nrf2 and DAF-16/FOXO and enhancing the expression of relevant anti-aging genes. BLI and ITC analysis showed that the insulin-receptor binding, the first step to activate IIS pathway, was impeded by the engagement of WGPA-2-HG/WGPA-3-HG with insulin. By chemical modifications, we found that high methyl-esterification of WGPA-2-HG/WGPA-3-HG was detrimental for their longevity-promoting activity. These findings provided novel insight into the precise molecular mechanism for the longevity-promoting effect of ginseng pectins, and suggested a potential to utilize the ginseng HG pectins with appropriate DM values as natural nutrients for increasing human longevity.

Ginseng rusty root symptoms result from nitric oxide stress in soil.

Ginseng, from the roots of Panax ginseng C. A. Meyer, is a widely used herbal medicine in Asian countries, known for its excellent therapeutic properties. The growth of P. ginseng is depend on specific and strict environments, with a preference for wetness but intolerance for flooding. Under excessive soil moisture, some irregular rust-like substances are deposited on the root epidermis, causing ginseng rusty symptoms (GRS). This condition leads to a significant reduce in yield and quality, resulting in substantial economic loses. However, there is less knowledge on the cause of GRS and there are no effective treatments available for its treatment once it occurs. Unsuitable environments lead to the generation of large amounts of reactive oxygen species (ROS). We investigated the key indicators associated with the stress response during different physiological stages of GRS development. We observed a significant change in ROS level, MDA contents, antioxidant enzymes activities, and non-enzymatic antioxidants contents prior to the GRS. Through the analysis of soil features with an abundance of moisture, we further determined the source of ROS. The levels of nitrate reductase (NR) and nitric oxide synthase (NOS) activities in the inter-root soil of ginseng with GRS were significantly elevated compared to those of healthy ginseng. These enzymes boost nitric oxide (NO) levels, which in turn showed a favorable correlation with the GRS. The activities of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase first rose and then decreased as GRS developed. Excess soil moisture causes a decrease in oxygen levels. This activated NR and NOS in the soil, resulting in a production of excess NO. The NO then diffused into the ginseng root and triggered a burst of ROS through NADPH located on the cell membrane. Additionally, Fe2+ in soil was oxidized to red Fe3+, and finally led to GRS. This conclusion was also verified by the Sodium Nitroprusside (SNP), a precursor compound producing NO. The presence of NO from NR and NOS in water-saturated soil is responsible for the generation of ROS. Among these, NO is the main component that contribute to the occurrence of GRS.

Biocontrol of rusted root rot in Panax ginseng by a combination of extracts from Bacillus amyloliquefaciens YY8 crude protein and Enterobacteriaceae YY115 ethyl acetate.

BACKGROUND: Rusted root rot is one of the most common root diseases in Panax ginseng, and Cylindrocarpon destructans is one of the main pathogenic fungus. The objective of this study was to screen and explore the extracts of biocontrol bacteria isolated from ginseng rhizosphere soil against Cylindrocarpon destructans. RESULTS: Bacterial strains Bacillus amyloliquefaciens YY8 and Enterobacteriacea YY115 were isolated and found to exhibit in vitro antifungal activity against C. destructans. A combination of crude protein extract from B. amyloliquefaciens YY8 and ethyl acetate extract from Enterobacteriacea YY115 in a 6:4 ratio exhibited the strongest antifungal activity against C. destructans. Measurements of electrical conductivity, protein content, and nucleic acid content in suspension cultures of C. destructans treated with a mixture extracts indicated that the extracts disrupted the cell membranes of rusted root rot mycelia, resulting in the leakage of electrolytes, proteins, and nucleic acids from the cells, and ultimately inhibiting the growth of C. destructans. The combined extracts suppressed the infection of ginseng roots discs by C. destructans effectively. CONCLUSION: The extracts obtained from the two bacterial strains effectively inhibited C. destructans in P. ginseng. It can provide scientific basis for the development of new biological control pesticides, reduce the use of chemical pesticides, and promote the sustainable development of agriculture.

Monoclonal antibody-based enzyme-linked immunosorbent assay for quantification of majonoside R2 as an authentication marker for Nngoc Linh and Lai Chau ginsengs.

Background: Recent years have witnessed increasing interest in the high amount of ocotillol-type saponin in Panax vietnamensis, particularly in relation to majonoside R2 (MR2). This unique 3%-5% MR2 content impart Ngoc Linh and Lai Chau ginsengs with unique pharmacological activities. However, in the commercial domain, unauthentic species have infiltrated and significantly hindered access to the authentic, efficacious variety. Thus, suitable analytical techniques for distinguishing authentic Vietnamese ginseng species from others is becoming increasingly crucial. Therefore, MR2 is attracting considerable attention as a target requiring effective management measures. Methods: An enzyme-linked immunosorbent assay (ELISA) was developed by producing monoclonal antibodies against MR2 (mAb 16E11). The method was thoroughly validated, and the potential of the immunoassay was confirmed by high-performance liquid chromatography with ultraviolet spectroscopy. Furthermore, ELISA was applied to the assessment of the MR2 concentrations of various Panax spp., including Korean, American, and Japanese ginsengs. Results and conclusions: An icELISA using mAb 16E11 exhibited linearity between 3.91 and 250 ng/mL of MR2, with detection and quantification limits of 1.53 and 2.50 - 46.6 ng/mL, respectively. Based on this study, the developed icELISA using mAb 16E11 could be a valuable tool for analyzing MR2 level to distinguish authentic Ngoc Linh and Lai Chau ginsengs from unauthentic ones. Furthermore, the analysis of the samples demonstrated that Ngoc Linh and Lai Chau ginsengs exhibit a notably higher MR2 value than all other Panax spp. Thus, MR2 might be their ideal marker compound, and various bioactivities of this species should be explored.

Effect of ginseng and ginsenosides on attention deficit hyperactivity disorder: A systematic review.

Attention deficit hyperactivity disorder (ADHD) is a rapidly increasing neurodevelopmental disorder but currently available treatments are associated with abuse risk, side effects, and incomplete symptom relief. There is growing interest in exploring complementary options, and ginseng has gained attention for its therapeutic potential. This systematic review aimed to assess current evidence on the efficacy of ginseng and its active components, ginsenosides, for ADHD. Eligible studies were identified through searches of PubMed, Embase, Cochrane Library, and Web of Science, up to June 2023. The inclusion criteria included both human and animal studies that investigated the effects of ginseng or ginsenosides on ADHD. The risk of bias was assessed according to study type. Six human studies and three animal studies met the inclusion criteria. The results suggest that ginseng and ginsenosides may have beneficial effects on ADHD symptoms, particularly inattention, through dopaminergic/norepinephrinergicmodulation and BDNF/TrkB signaling. Ginseng and ginsenosides have promising potential for ADHD treatment. Due to limitations in evidence quality, such as the risk of bias and variability in study designs, larger controlled studies are essential. Integrating ginseng into ADHD management may have valuable implications for individuals seeking well-tolerated alternatives or adjunctive therapies.

Enhanced immunity effect of Korean Red Ginseng capsule: A randomized, double-blind and placebo-controlled clinical trial.

Background: As a physiological function of body, immunity can maintain health by identifying itself and excluding others. With economic development and increasingly fierce social competition, the number of sub-healthy population is gradually increasing, and the most basic problem exposed is human hypoimmunity. Hypoimmunity can be manifested as often feeling tired, catching colds, mental depression, etc. In order to enhance immunity, eating healthy foods with the effect of enhancing immunity may become an effective choice. KRG has pharmacological effects of enhancing immunity. Because the screening and evaluation method of immune population are not unified, there are relatively few KRG immunity tests for sub-health population. It is of great significance to study the effect of KRG on people with hypoimmunity to improve sub-health status. Methods: This was a 180-day, randomized, double-blind, placebo-controlled clinical trial. According to the trial scheme design, 119 qualified subjects were included and randomly divided into the test group taking KRG and the placebo control group. Subjects need to check safety indicators (blood pressure and heart rate, blood routine, liver and kidney function, urine routine and stool routine) and efficacy indicators (main and secondary) inspection at baseline, efficacy indicators inspection during the mid-term of the test (90th days of administration), safety and efficacy indicators inspection after the test (180th days of administration). Results: After the test, the safety indicators of placebo control group and KRG test group were basically within the normal range, and there is no significant difference in fireness score between the two groups. Through follow-up interviews, it was found that the subjects in the test group and the control group had no adverse reactions and allergic reactions such as nausea, flatulence, diarrhea, and abdominal pain during the test period. Self-comparison of the test group, the results of the main efficacy indicators: (1) immune related health scores were significantly improved in the mid-term and after the test (P < 0.01), (2) CD3 and CD4/CD8 increased significantly after the test (P < 0.05), (3) IgG, IgA, IgM and WBC increased significantly in the mid-term and after the test (P < 0.01); the results of the secondary efficacy indicators: (1) TNF-α decreased significantly in the mid-term (P < 0.05), IFN-γ decreased significantly in the mid-term (P < 0.01), (2) NK increased significantly in the mid-term and after the test (P < 0.05), (3) monocyte increased significantly in the mid-term and after the test (P < 0.01). Inter-group comparison of the test group and the control group, the results of the main efficacy indicators: (1) immune related health scores were higher than that of the control group in the mid-term and after the test (P < 0.01), (2) IgA of the test group was higher than that of the control group in the mid-term and after the test (P < 0.05); the results of the secondary efficacy indicators: (1) WBC of the test group was higher than that of the control group in the mid-term (P < 0.05); (2) monocytes of the test group were higher than that of the control group in the mid-term and after the test (P < 0.05), neutrophils of the test group were higher than that of the control group in the mid-term (P < 0.05). Conclusion: Taking KRG has no adverse effects on the health of the subjects. According to the standard of clinical trial scheme, the immune related health scores and IgA in the main efficacy indicators were positive, which shows that KRG is helpful in enhancing human immunity.
