Pharmaceuticals (Basel) 2023; 16:1371. [PMID: 37895842 PMCID: PMC10610176 DOI: 10.3390/ph16101371] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 09/21/2023] [Accepted: 09/26/2023] [Indexed: 10/29/2023] Open
Abstract
Alternative medicines, especially herbal remedies, have been employed to treat infections and metabolism-related chronic inflammation because their safety and multidimensional therapeutic potential outweigh those of synthetic drugs. So Shiho Tang (SSHT), a well-known Oriental prescription (Xiao Chai Hu Tang in Chinese) composed of seven herbs, is traditionally prescribed to treat various viral infections and chronic metabolic disorders in Asia with or without the support of other natural medicines. To provide a general background on how SSHT is used as a medicinal alternative, we conducted a scoping review using the PubMed database system. Among the 453 articles, 76 studies used aqueous extracts of SSHT alone. This result included seven clinical studies and 69 basic studies: cell-based, animal-based, and ex vivo studies. The in vitro and clinical reports mainly focus on hepatic infection and hepatocarcinoma, and the documentation of in vivo tests of SSHT presents a wide range of effects on cancer, fibrosis, inflammation, and several metabolic disorder symptoms. Additionally, among the seven clinical records, two reverse-effect case studies were reported in middle-aged patients. In brief, this systematic review provides general knowledge on the natural remedy SSHT and its potential in phytotherapeutic primary health care.

Abstract
Backgroud Soshiho-tang (SST, Xiao-chai-hu-tang in Chinese and Sho-saiko-to in Japanese), an oriental herbal formula, is used for treatment of chronic liver diseases. Although many researchers have studied the pharmacological properties of SST, information about its safety and toxicity is limited. Therefore, we evaluated the potential safety of SST in Sprague–Dawley rats over a period of 4-weeks. Methods The SST was administered once daily by gavage to male and female rats at doses of 0, 500, 1000 and 2000 mg/kg/day for 4 weeks. We measured the body weight, mortality, food consumption, ophthalmoscopy, urinalysis, hematology, serum biochemistry, gross pathological findings, absolute/relative organ weights and histopathology. In addition, we analyzed the component of SST and measured the stability of its component in SST according to study periods using high performance liquid chromatography. Results The SST treatment did not result in any toxicologically significant changes in mortality, food consumption, ophthalmoscopy, urinalysis, hematology, serum biochemistry, gross pathological findings, absolute/relative organ weights and histopathology, except for salivation and reduction in body weight in the 2000 mg/kg/day male group. These findings in the 2000 mg/kg/day male group are considered toxicologically insignificant because they are not accompanied by other pathological findings, including in hematology, serum biochemistry and histopatholgy, and they do not exhibit a dose–response relationship. SST is detected three components including liquiritin, baicalin, and glycyrrhizin. In addition, there were not observed the significant differences among the contents of three components in SST according to storage periods. Conclusion These results indicate that SST may be a safe material. Based on these results, the no-observed-adverse-effect level was more than 2000 mg/kg for both genders.

Renal protective effect of xiao-chai-hu-tang on diabetic nephropathy of type 1-diabetic mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2012; 2012:984024.

Abstract
Xiao-Chai-Hu-Tang (XCHT), a traditional Chinese medicine formula consisting of seven medicinal plants, is used in the treatment of various diseases. We show here that XCHT could protect type-1 diabetic mice against diabetic nephropathy, using streptozotocin (STZ)-induced diabetic mice and high-glucose (HG)-exposed rat mesangial cell (RMC) as models. Following 4 weeks of oral administration with XCHT, renal functions and renal hypertrophy significantly improved in the STZ-diabetic mice, while serum glucose was only moderately reduced compared to vehicle treatment. Treatment with XCHT in the STZ-diabetic mice and HG-exposed RMC resulted in a decrease in expression levels of TGF-β1, fibronectin, and collagen IV, with concomitant increase in BMP-7 expression. Data from DPPH assay, DHE stain, and CM-H2DCFDA analysis indicated that XCHT could scavenge free radicals and inhibit high-glucose-induced ROS in RMCs. Taken together, these results suggest that treatment with XCHT can improve renal functions in STZ-diabetic mice, an effect that is potentially mediated through decreasing oxidative stress and production of TGF-β1, fibronectin, and collagen IV in the kidney during development of diabetic nephropathy. XCHT, therefore merits further investigation for application to improve renal functions in diabetic disorders.

Abstract
To search for an effective antiviral agent, this study tested the hypothesis that sho-saiko-to (Xiao-Chai-Hu-Tang) and crude saikosaponins possess the activity directly against HBV and could affect the expressions of viral antigens, HBeAg and HBsAg, in HepG(2) 2.2.15 cell model. The viral amount and viral antigens in the suspension were estimated by quantitative real time PCR and enzyme-linked immunosorbent assay (ELISA), respectively. The results showed that sho-saiko-to could inhibit the production of HBV (p < 0.0001), 20 microg/ml sho-saiko-to was efficacious at day-3 of treatment and 10 microg/ml at day-6. The calculated IC(50) and CC(50) of sho-saiko-to were 55.76 microg/ml and 372 microg/ml, respectively, with a selectivity index of 6.67. Crude saponin of B. chinense could also inhibit the replication of HBV (p < 0.0001). Owing to the anti-neoplastic activity of sho-saiko-to and saikosaponin, their calculated CC(50) and selectivity index might be under-estimated. Sho-saiko-to also decreased the expression of HBeAg with the minimal effective concentration of 20 microg/ml. Sho-saiko-to contained too little saikosaponin. Therefore, the anti-HBV activity of sho-saiko-to might not be mediated by saikosaponin. Sho-saiko-to could be supplementary to nucleotide analogues to minimize the recurrence of viremia after its discontinuation.

Abstract
Coxsackie B virus type 1 (CVB1) infection is known to cause high morbidity and mortality in children, however, there is no effective drug for treating this disease. The present study aimed to examine the antiviral activity of xiao chai hu tang (XCHT), a popular herbal drug for treating viral and bacterial infections, against CVB1 infection and its mechanisms of action. Our data showed that XCHT neutralized the CVB1-induced cytopathic effect in human neonatal foreskin fibroblast cell line (CCFS-1/KMC), with IC50 (virus-induced cytopathic effect by 50%) and EC50 (concentration of 50% effectiveness) values around 12.39 and 50.93 microg/ml, respectively. Its CC50 (concentration of 50% cellular cytotoxicity) and SI (selective index) values were 945.75 microg/ml and 18.92, respectively. These results suggest that XCHT possessed anti-CVB1 activity, and showed no effect on CCFS-1 cell viability and growth at concentration 250 microg/ml. The time-of-addition studies showed that XCHT (50, 100 and 200 microg/ml) added at various time of preinfection (-1 to -3 h), coinfection (0 h) and postinfection (1 approximately 3 h) could inhibit CVB1 infection. Interestingly, XCHT also showed an inhibition on viral replication through the induction of IFN-alpha/beta expression. In conclusion, XCHT possessed antiviral activity against CVB1 infection. It interfered the early stage of viral replication (prophylactic effect) and viral replication after infection (therapeutic effect) through the induction of Type I interferon expression.

Abstract
Xiao-chai-hu-tang (XCHT) is an important Chinese herbal prescription for curing many types of liver diseases. The contents of bioactive constituents (saikosaponins a, c and d, baicalin, baicalein, and glycyrrhizic acid), and antioxidant properties of XCHT extracts prepared with ultrasound-assisted (US) extraction in combination with ethanol (up to 95%) as extraction modifier were studied. The results showed that the US extraction significantly increased the bioactive constituents concentrations and antioxidant properties of XCHT extracts when compared with the XCHT prepared with traditional boiling-water extraction. Among the XCHT extracts made with US extraction, the sample prepared with 95% ethanol showed the highest bioactive constituent concentrations and the best antioxidant functionalities. The results suggest that US extraction of XCHT is feasible to replace the traditional time-consuming and low efficiency preparation procedure in the future modernized and commercialized manufacture of this highly valuable Chinese herbal medicine.

Abstract
Sho-saiko-to (SST) was introduced into Japan as an oriental classical medicine from China approximately 1500 years ago, and it is currently the most representative Kampo medicine (traditional Japanese medicine). SST is manufactured in Japan as an ethical drug on a modern industrial scale in which the quality of ingredients is standardized with Good Manufacturing Practices (GMP) regulation. SST is widely used for the treatment of chronic hepatitis. Experimental and clinical studies including multi-center, placebo-controlled, double-blind studies have demonstrated the various pharmacological effects of SST. SST is prepared from the hot water extraction of seven raw materials, therefore many kinds of constituents are included. Three-dimensional (3D) HPLC analysis is useful for obtaining many kinds of constituents, especially low molecular ultraviolet (UV) quenching compounds, contained in SST as well as its fractions. Fingerprint pattern provided by 3D HPLC analysis makes possible to identify the overall-viewing of SST. Databases of UV spectra of the components of medicinal herbs obtained by reversed-phase (RP) HPLC using a photodiode array (PDA) and fingerprint patterns of crude drugs made by 3D HPLC analysis facilitate the identification, analysis and quality of herbal drugs. Studies using both PDA HPLC and an amino acid analysis with a fluorometric detector have found that SST contains fifteen major low molecular compounds (i.e. baicalin, wogonin-7-O-glucuronide, liquiritin, their three aglycons, liquiritin apioside, glycyrrhizin, saikosaponin b1, saikosaponin b2, ginsenoside Rg1, ginsenoside Rb1, (6)-gingerol, (6)-shogaol and arginine). These compounds have various pharmacological actions, and are assumed to be responsible, at least partly, for the pharmacological effects of SST. Although there have only been a few investigations on high molecular compounds with pharmacological actions contained in SST, several kinds of polysaccharides have been isolated from constituent herbs of SST. This review paper summarizes analytical methods of separation, isolation and identification of compounds with biological activities from SST, which is a mixture drug of medicinal herbs. Accordingly, this paper would not focus on methods of separation, isolation and analysis of particular compounds from each constituent herb of SST.

Abstract
Sho-saiko-to (SST), a Chinese/Japanese traditional herbal medicine, has been widely used to treat chronic hepatitis in Japan, and the immunomodulatory properties of SST are likely to mediate its beneficial effect. In the present study, we examined the effects of SST and its various ingredients on the count and proliferation of T-cell subsets in cultured splenocytes and hepatic mononuclear cells. SST, wogonin-7-O-glucuronoside (a major SST ingredient), and wogonin (an intestinal metabolite of wogonin-7-O-glucuronoside) increased CD4/CD8 ratio via a decrease of CD8+ T-cell counts with no effect on CD4+ T-cell counts. Flow cytometric analyses of viability, proliferation, and cell cycle revealed that wogonin suppressed CD8+ T-cell proliferation without inducing cell death. SST and wogonin administered to mice increased the CD4/CD8 ratio in hepatic mononuclear cells but not in splenocytes. These findings suggest that SST may modulate the CD4/CD8 ratio via the selective inhibition of CD8+ T-cell proliferation by the SST ingredient wogonin-7-O-glucuronoside or its metabolite wogonin.

Abstract
The RT-PCR method was employed to determine the cytokine mRNA expression of human peripheral lymphocytes induced by the Japanese herbal medicine Sho-saiko-to (TJ-9). The results showed that the mRNA expression of IL-12, IL-1beta, IL-10, TNF-alpha, G-CSF, and IFN-gamma increased after 6 hr in culture. This is the first reported finding that TJ-9 is an IFN-gamma inducer. Next, cytokine mRNA expression was semi-quantitatively measured using the Gel Doc system with a CCD camera and then statistically analyzed in order to determine which component of TJ-9 was the true cytokine inducer. The results showed that the scutellaria root is the main component inducing the cytokines, while the glycyrrhiza root is the secondary component. When the cytokine concentrations in the supernatants of cell cultures were measured by ELISA, the levels of IL-12, IL-1beta, IL-10, TNF-alpha, and G-CSF reflected mRNA expression levels in the cell fraction. However, the level of IFN-gamma was below the detectable limit. The effects of various reagents on many different kinds of cytokine mRNA expression could be analyzed objectively in a short time using the Gel Doc system. Many important findings could be demonstrated by this simple, easy, sensitive, and cheap method. After the clinical significance of cytokine analysis is confirmed, this method may become a useful clinical examination tool.

Abstract
The use of alternative medicine, including consumption of herbal products and dietary supplements, has been increasing substantially both in the United States and in Western Europe. One area that is garnering increased attention is the use of Oriental Medicine including Kampo, or Japanese herbal medicine. Herein, we review representative examples of research available on the most common use of Kampo medicinals, namely to improve the immune response. We also provide an extensive background on the history of Kampo. There are more than 210 different Kampo formulae used in Japan and most uses of Kampo are to modulate the immune response, i.e. to improve immunity. We have extracted data on seven common Kampo medicinals, and the data are reviewed with respect to in vitro and in vivo activities for both humans and experimental animals; the ingredients as well as the problems with classification of these materials are presented. Research suggests that Kampo herbals are biologically active and may have therapeutic potential. While it is believed that Kampo medicines have few side effects, there is a paucity of data on their toxicity as well as a relative lack of knowledge of the bioactive constituents and potential drug interactions of these agents.

Abstract
Sho-saiko-to (SST), a Chinese/Japanese herbal medicine (Kampo medicine) widely used to treat chronic hepatitis in Japan, is known to modulate immune responses, and thus its immunomodulating activity may be responsible for its bi-directional effects on the lungs as therapeutic efficacy in various lung diseases and involvement in development of interstitial pneumonia. We administered SST to BALB/c mice orally and examined the lung tissue levels of pro/anti-inflammatory cytokines, interleukin-1beta (IL-1beta), tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6), and the effects of SST on acute lung injury induced by instillation of lipopolysaccharide (LPS) or IL-1. Although SST had no effect on lung TNF-alpha or IL-1beta level, it increased IL-6. Investigation of active fractions of SST suggested that multiple ingredients were supposed to be responsible for IL-6-inducing activity. Liquiritigenin, a metabolite of liquiritin which is one of the major ingredients in SST enhanced in vitro IL-6 production in anti-CD3 monoclonal antibody (anti-CD3 mAb)-stimulated lung mononuclear cells in a cell-type specific and dose-dependent manner. SST suppressed LPS-induced lung injury at the later phase when lung leak was evident while being ineffective on initial neutrophil sequestration to the lung in these models. These findings suggest that SST modulates lung inflammation by regulating local immune response.
