HERBAL CONTROL OF MOSQUITO LARVAE

Mosquitoes are the vectors for the dreadful diseases of mankind. For control of larval stages of mosquito, herbal plant extracts/ botanical insecticides are being tried. In the present study aqueous extract of some traditional medicinal herbal plants i.e. Neem ( Azadirechta indica ), Tobacco ( Nicotiana tabacum ), Turmeric ( Curcuma longa ), Tulasi ( Ocimum santum ), and Ginger ( Zingiber officinale ) were tested for their Larvicidal activity. The successful attempt is made to kill the larvae, the premature stage of mosquitoes by using safe and socio-economical herbal plant extract mixtures. Ginger+Tobacco, Neem+Tobbaco and Ginger Neem, Turmeric, Tobacco and Tulasi showed highest larvicidal activity. The results obtained show that this plant material exhibited larvicidal activity and could be considered as potent natural larvicidal agent without any toxic effects.

Taste evaluation of multicomponent mixtures using a human taste panel, electronic taste sensing systems and HPLC

Various methods are known for the evaluation of taste. The most reliable but contemporarily least objective data are obtained using human taste panels. Analytical tools like electronic taste sensing systems and chromatographic analysis enable a less subjective evaluation.In this study, two herbal extracts as well as lozenges containing those extracts were investigated by HPLC measurements, two electronic taste sensing systems and a human taste panel. The resulting data were compared to each other and evaluated in terms of their informative value.Several sensors of the electronic tongues were able to detect differences between the unprocessed herbal extracts and lozenges. However, different extract concentrations in the fabricated lozenges could not be investigated by taste sensing systems as all sensor sets led to similar results.Via sensory two-row-triangular test, the human taste panel identified the lozenge with the lowest herbal extract amount to be the only differing sample (significance level α=0.05). Different herbal extract mixtures and deviations of extract concentration in lozenges remained undetected.These deviations were proven by HPLC measurements.Up to now, complementary measurements using different analytical tools and human subjects are recommended for complete information about products’ taste.

In Vivo and in Vitro Animal Investigation of the Effect of a Mixture of Herbal Extracts from Tribulus terrestris and Cornus officinalis on Penile Erection

Herbal preparations have long been used as folk remedies for erectile dysfunction (ED). This study examined the effects of Tribulus terrestris and Cornus officinalis extracts on relaxation of the smooth muscle of the corpus cavernosum (CC), their mechanisms of action, and the effects of oral administration of a mixture of the herbal extracts on penile erection. The relaxation effects and the mechanisms of action of T. terrestris extract, C. officinalis extract, and the mixture of both extracts on the rabbit CC were investigated in an organ bath. To evaluate whether the relaxation response of the CC shown in an organ bath occurs in vivo, intracavernous pressure (ICP) was calculated in rats after oral administration for a month. Additionally, adenosine 3',5'-cyclic monophosphate (cAMP) and guanosine 3', 5'-cyclic monophosphate (cGMP) in the CC were measured using immunoassay. Smooth muscle relaxation was expressed as the percent decrease in precontraction induced by phenylephrine. ICP was assessed in rats after the oral administration of a mixture of both extracts for 1 month and changes in cGMP and cAMP concentrations were measured based on the concentration of the mixture of both extracts. T. terrestris extract, C. officinalis extract, and the mixture of both extracts showed concentration-dependent relaxation effects of the CC. In both the endothelium-removed group and N(G)-nitro-L-arginine methyl ester pretreatment group, T. terrestris extract inhibited relaxation. ICP measured after oral administration of the extract mixture for a month was higher than that measured in the control group, and a significant increase in cAMP was observed in the mixture group. T. terrestris extract and C. officinalis extract exhibited concentration-dependent relaxation in an organ bath. In the in vivo study of the extract mixture, ICP and cAMP was significantly potentiated. Accordingly, the mixture of T. terrestris extract and C. officinalis extract may improve erectile function.

Effect of herbal extracts on piglet performance and small intestinal epithelial villi

The effect of a mixture of herbal extracts on piglet performance was estimated on 178 piglets allocated to 3 groups comprising 6 litters each. Group I (control) was fed with the standard barley-wheat-soybean mixture. Group II received the same mixture supplemented with a blend of formic and propionic acids. Group III received the basal diet supplemented with a mixture of water extracts from sage, lemon balm, nettle and coneflower (20, 30, 30, and 20%, respectively) at 500 mg/kg feed. The experiment lasted for 84 days but on day 56 six piglets from each group were slaughtered and their gastrointestinal tract was removed. Apparent digestibility was estimated using the Cr<sub>2</sub>O<sub>3</sub> indicator method. Acidity of digesta was measured in the stomach, ileum, and caecum, and volatile fatty acid content was evaluated in the ileum and caecum. Amounts of bacteria and morphological structure were evaluated in the ileal digesta and epithelium, respectively. In the experimental groups less dead and culled piglets were observed than in the control group. Piglets in the herb-supplemented group grew faster than control animals and showed significantly higher final average body weights. There was no significant difference in feed utilization. Acetic acid content was higher in both groups receiving supplements. The amount of propionic acid in the caecum of animals from the herb-supplemented group was lower than in animals from groups I and II. There were no significant differences in bacteria population in ileum chyme. The herbal extract improved the structure of the ileal epithelium by significantly increasing villus height. Better digestibility of nutrients could be due to higher villi in this group.  

Safety and Efficacy of Setarud (IMOD TM ) Among People Living with HIV/AIDS: A Review

The broad use of highly active anti-retroviral therapy (HAART), especially in developing world, has been associated with several problems such as lactic acidosis, lipodistrophy, pancreatitis, hyperlipidemia, insulin resistance and hepatotoxicity. Extensive use of HAART has also resulted in emergence of resistant HIV variants. Thereby, a pressing need for development of novel and cost-effective agents arises from these limitations. Setarud (IMOD™) is a safe, naturally- derived immunomodulator that was introduced for treatment of HIV patients in Iran. It is prepared as a mixture of herbal extracts including Tanacetum vulgare (tansy), Rosa canina and Urtica dioica (nettle) in addition to selenium, flavonoids and carotenes. Tanacetum vulgare may relieve anti-inflammatory symptoms and Rosa canina defers blood glucose and cholesterol elevation. Extracts from Urtica dioica may prevent maturation of myeloid dendritic cells and reduce T cell responses. A significant rise of CD4 count was observed in HIV patients treated by IMOD™ in clinical trial phases, which could be explained by its immunomodulatory effects. Anti-oxidative activity of compounds in IMOD™ might play a role in the clinical outcomes of patients treated with this drug. Moreover, IMOD™ may show improving activity upon lipid profile and liver metabolism. According to studies on IMOD™, it seems that IMOD™ has minor side effects. IMOD™ with international publication number WO 2007/087825 A1 is an herbal extract which includes Rosa canina, Urtica dioica, Tanacetum vulgare, and selenium comprising a treatment by pulsed electromagnetic field of high frequency and is useful in treatment of HIV infection and AIDS.

In vitro and in vivo protective effects of fermented preparations of dietary herbs against lipopolysaccharide insult

Lipopolysaccharide (LPS) is known to produce endotoxic shock by triggering systemic inflammatory responses. Here, we evaluated the protective effects of three fermented/re-fermented herbs, Rhizoma Atractylodis Macrocephalae, Massa Medicata Fermentata, and Dolichoris Semen, in an LPS-mediated inflammatory insult, either individually in vitro using RAW264.7 cells or in combination in in vivo using rats. In general, each of the fermented herbs showed appreciable in vitro anti-inflammatory activity, although the degree of this activity varied with the herb used. Moreover, a mixture of fermented herbal extracts in combination with probiotics significantly attenuated the blood endotoxin and CRP levels, as well as the gut permeability, and significantly augmented the intestinal Lactobacillus spp. colonisation in LPS-treated rats. However, these effects were not observed following the administration of the corresponding mixture of unfermented herbal extracts. Thus, our results highlight the beneficial impacts of the use of fermented herb products with probiotics to combat LPS-mediated inflammatory insults.

Protective Effects of HV-P411 Complex Against D-Galactosamine-Induced Hepatotoxicity in Rats

This study examined the hepatoprotective effect of the HV-P411 complex, an herbal extract mixture from the seeds of Vitis vinifera, Schisandra chinensis and Taraxacum officinale, against D-galactosamine (D-GalN)-induced hepatitis. Hepatotoxicity was induced by D-GalN (700 mg/kg, i.p.), and the HV-P411 complex was administered orally 48, 24, and 2 h before and 6 h after D-GalN injection. Increases in serum aminotransferase activity and lipid peroxidation and a decrease in hepatic glutathione content were attenuated by the HV-P411 complex 24 h after D-GalN treatment. The HV-P411 complex attenuated the increases in serum tumor necrosis factor-α, interleukin (IL)-6 level and cyclooxygenase-2 protein production and their mRNA expressions, while increases in serum IL-10 level and heme oxygenase-1 protein production and their mRNA expressions were augmented by the HV-P411 complex. The increased translocation of nuclear factor-κB and c-Jun phosphorylation were attenuated by treatment with the HV-P411 complex. Our results suggest that the HV-P411 complex prevents D-GalN-induced hepatotoxicity via antioxidative and anti-inflammatory activities.

Separation and identification of components of the multi-component herbal drug prostanorm

Prostanorm is a multi-component Russian herbal drug comprising a mixture of the extracts of St. John’s wort (Hypericum perforatum L.), goldenrod (Solidago canadensis L.), licorice root (Glycyrrhiza glabra L.), and purple coneflower (Echinacea purpurea L. Moench) rhizomes and roots in equal amounts. An HPLC method for qualitative analysis of the components in the mixed phytopreparation and extracts of all individual raw materials has been developed. The optimum chromatographic conditions for HPLC determination of components of the herbal drug have been determined. Components of the mixed extract are satisfactorily separated and resolved by using an octadecylsilane adsorbent and gradient elution with a mixture of acetonitrile, methanol, phosphate buffer, and dimethylformamide. HPLC analysis was optimized according to chromatographic parameters. The basic biologically active components of the herbal mixture and individual extracts of all herbs were identified. The proposed method ensures determination of the identity of the herbal drug Prostanorm in the form of liquid extract for peroral administration.

Chinese herb mix Tiáo-Gēng-Tāng possesses antiaging and antioxidative effects and upregulates expression of estrogen receptors alpha and beta in ovariectomized rats

BackgroundHerb mixtures are widely used as an alternative to hormonal therapy in China for treatment of the menopausal syndrome. However, composition of these herb mixtures are complex and their working mechanism is often unknown. This study investigated the effect of Tiáo-Gēng-Tāng (TG-decoction), a Chinese herbal mixture extract, in balancing female hormones, regulating expression of estrogen receptors (ERs), and preventing aging-related tissue damage.MethodsOvariectomized 5-month-old female rats were used to model menopause and treated with either TG-decoction or conjugated estrogen for 8 weeks. Estradiol (E2), luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were measured in serum and in the hypothalamus. Hypothalamic expression of estrogen receptor (ER) alpha and beta were studied by real-time PCR and western blotting. Total antioxidant capacity (T-AOC), oxidation indicator superoxide dismutase (SOD) activity and tissue damage parameter malondialdehyde (MDA) were measured using standard assays. Aging-related ultrastructural alterations in mitochondria were studied in all animals by transmission electron microscopy.ResultsTG-decoction-treatment elevated E2 and lowered FSH in serum of ovariectomized rats. The potency and efficacy of TG-decoction on the hypothalamus was generally weaker than that of conjugated estrogens. However, TG-decoction was superior in upregulating expression of ERα and β. TG-decoction increased hypothalamic SOD and T-AOC levels and decreased MDAlevels and mitochondrial damage in hypothalamic neurons.ConclusionsTG-decoction balances female hormones similarly to conjugated estrogens but less effectively. However, it is superior in up regulating ERα and β and exhibits antioxidative antiaging activities. Whilst it shares similar effects with estrogen, TG-decoction also seems to have distinctive and more complex functions and activities.

Zyflamend Reduces the Expression of Androgen Receptor in a Model of Castrate-Resistant Prostate Cancer

Prostate cancer is the most commonly diagnosed solid malignancy, and tumor cells eventually transform to castrate resistance through multiple pathways including activation of the androgen receptor via insulin-like growth factor receptor (IGF-1R) signaling involving phospho-AKT (pAKT). In this study, a mixture of herbal extracts, Zyflamend®, was used as a treatment in a model of castrate-resistant prostate cancer using CWR22Rv1 cells. Zyflamend reduced androgen receptor and IGF-1R expression along with a reduction of IGF-1-mediated proliferation of CWR22Rv1 cells. IGF-1 induced downstream AKT phosphorylation; however, the induction of pAKT was not associated with androgen receptor expression. Further, constitutively active form of AKT had no effect on nuclear expression of androgen receptor, indicating that upregulation of pAKT did not promote androgen receptor expression or nuclear translocation in castrate-resistant CWR22Rv1 cells. Conversely, Zyflamend reduced androgen receptor expression following IGF-1 stimulation and in cells overexpressing pAKT. These results demonstrated that Zyflamend inhibited IGF-1-stimulated cell growth, IGF-1R expression, and androgen receptor expression and its nuclear localization, but these effects were not dependent upon phosphatidylinositol 3-kinase/pAKT signaling. In conclusion, Zyflamend decreased cell proliferation and inhibited IGF-1R and androgen receptor expression in a phosphatidylinositol 3-kinase/pAKT independent manner.

Physiological effects of an herbal extract mixture containing Acanthopanax senticosus Harms on the development, reproduction, and lipid metabolism of Caenorhabditis elegans

Hot Topic: Editorial [Traditional Chinese Medicine] (Ping Zhou)

Medicinal herbs have been used to treat human diseases in China for thousands of years. There has been great interest in the research and development of bioactive components from herbal medicines. Significant pharmacological properties have been demonstrated for many herbs over recent decades. Not only important in China, herbal preparations are becoming increasingly popular in Europe and North America as complementary therapeutics. Traditional Chinese Medicine (TCM) is usually a mixture of herbal plants or extracts which comprise hundreds of different constituents with widely differing physiochemical properties. The qualification and quantitative analysis of active constituents from this mixture is often a challenging task especially when the relevant compounds might be present in minute amounts only. Additional challenge is batch-to-batch inconsistency of constituents due to the natural variability of the herbal plants. Thus, there is a substantial need to use modern bioassay and analytical techniques, including developing high throughput and sensitive technologies, to determine active constituents and to monitor the quality control of herbal medicines. The rapid growth in proteomics, genomics and metabonomics provides a lot of new tools for the integration of traditional Chinese medicine with modern technology and systems biology. This special issue aims at providing the readers of CCHTS with a perspective of the technology developments and their applications in the rapid progress of up-to-date research in TCM. I would like to express my thanks to all the contributors for their valuable articles and to the referees for their constructive comments as well as to Professor Rathnam Chaguturu, the Editor-in-Chief, for his continuing support during the preparation of this issue.

Therapy with methanolic extract of Pterocarpus marsupium Roxb and Ocimum sanctum Linn reverses dyslipidemia and oxidative stress in alloxan induced type I diabetic rat model

Methanolic extracts of Pterocarpus marsupium Roxb (P. marsupium) and Ocimum sanctum Linn (O. sanctum) were prepared separately and then administered to both non-diabetic and alloxan induced diabetic adult female Wistar rats as a mixture of both at a dosage of 500mg/kg body weight, and its effect was checked on serum and tissue lipids together with corticosterone, estrogen and progesterone profile. Further, tissue load of metabolites (cholesterol), enzymatic and non-enzymatic antioxidant status together with lipid peroxidation levels and serum markers of hepatic and renal damage were also assessed. Results of the present study strongly support the possibility of this herbal combination in humans to meet the objective of achieving a holistic amelioration and cure of diabetes as, the herbal extract mixture of P. marsupium and O. sanctum has succeeded in not only rectifying dyslipidemia but also in restoring the endogenous antioxidant levels to the pre diabetic status. Herbal preparations are ideal candidates of choice and in this context, the present combination of P. marsupium and O. sanctum provides compelling evidence for a holistic efficacy in amelioration of associated diabetic manifestations/dysregulations.

Evaluation of the toxicological properties and hepatoprotective effects of PAI-N002, a mixture of herbal extracts, in rats

The short-term toxicity of PAI-N002, a mixture of Schizandra chinensis, Astragalus membranaceus, Artemisia capillaris, and Coriolus versicolor extracts (1 : 1 : 1 : 1), was evaluated in rats. This study also investigated the protective effect of PAI-N002 on liver injury induced by the co-administration of ethanol and carbon tetrachloride (EC) in rats. PAI-N002 was virtually non-toxic to rats after a single oral administration, with LD50 values > 5,000 mg/kg. The subacute toxicity study showed that 2-week repeated oral dose of PAI-N002 did not cause any adverse effects on clinical signs, body weight, food consumption, ophthalmoscopy, hematology, serum biochemistry, gross findings, and organ weights in rats given up to 1,000 mg/kg/day. When rats with EC-induced hepatotoxicity were treated with PAI-N002 at 250 mg/kg/day for 28 days, PAI-N002 treatment significantly improved EC-induced hepatic injury, as evidenced by the decline of serum AST and ALT activities and decreased histopathological alterations. PAI-N002 also had an antioxidant benefit by decreasing the lipid peroxidative product malondialdehyde and increasing the levels of the antioxidant glutathione and the activities of the antioxidant enzymes catalase, superoxide dismutase, and glutathione-S-transferase. These results indicate that the short-term treatment of rats with PAI-N002 has no harmful effects and that PAI-N002 has hepatoprotective and antioxidant properties in EC-induced chronic liver injury in rats.

Effect of Carnitine and herbal mixture extract on obesity induced by high fat diet in rats

BackgroundObesity-associated type 2 diabetes is rapidly increasing throughout the world. It is generally recognized that natural products with a long history of safety can modulate obesity.AimTo investigate the development of obesity in response to a high fat diet (HFD) and to estimate the effect of L-carnitine and an Egyptian Herbal mixture formulation (HMF) (consisting of T. chebula, Senae, rhubarb, black cumin, aniseed, fennel and licorice) on bodyweight, food intake, lipid profiles, renal, hepatic, cardiac function markers, lipid Peroxidation, and the glucose and insulin levels in blood and liver tissue in rats.MethodWhite male albino rats weighing 80-90 gm, 60 days old. 10 rats were fed a normal basal diet (Cr), 30 rats fed a high-fat diet (HFD) for 14 weeks during the entire study. Rats of the HFD group were equally divided into 3 subgroups each one include 10 rats. The first group received HFD with no supplement (HFD), the 2nd group HFD+L-carnitine and the third group received HFD+HMF. Carnitine and HMF were administered at 10th week (start time for treatments) for 4 weeks.Body weight, lipid profile & renal function (urea, uric acid creatinine) ALT & AST activities, cardiac markers, (LDH, C.K-NAC and MB) the oxidative stress marker reduced glutathione (GSH), and Malondialdehyde (MDA) catalase activity, in addition to glucose, insulin, and insulin resistance in serum & tissues were analyzed.ResultsData showed that feeding HFD diet significantly increased final body weight, triglycerides (TG), total cholesterol, & LDL concentration compared with controls, while significantly decreasing HDL; meanwhile treatment with L-carnitine, or HMF significantly normalized the lipid profile.Serum ALT, urea, uric acid, creatinine, LDH, CK-NAC, CK-MB were significantly higher in the high fat group compared with normal controls; and administration of L-carnitine or herbal extract significantly lessened the effect of the HFD. Hyperglycemia, hyperinsulinemia, and high insulin resistance (IR) significantly increased in HFD in comparison with the control group. The treatment with L-carnitine or HMF improved the condition. HFD elevated hepatic MDA and lipid peroxidation associated with reduction in hepatic GSH and catalase activity; whereas administration of L-carnitine or herbal extract significantly ameliorated these hepatic alterations.ConclusionHFD induced obesity associated with a disturbed lipid profile, defective antioxidant stability, and high values of IR parameters; this may have implications for the progress of obesity related problems. Treatment with L-carnitine, or HMF extract improved obesity and its associated metabolic problems in different degrees. Also HMF has antioxidant, hypolipidaemic insulin sensitizing effects. Moreover HMF might be a safe combination on the organs whose functions were examined, as a way to surmount the obesity state; and it has a distinct anti-obesity effect.

A Botanical Extract from Channel Flow Inhibits Cell Proliferation, Induces Apoptosis, and Suppresses CCL5 in Human Endometriotic Stromal Cells1

Growing evidence suggests that medicinal herbs have direct actions on endometrial cells. By screening multiple herbs using an in vitro model of endometriosis, we found that a commonly used herbal formula exerted considerable antiproliferative effects. Our purpose was to investigate the effects of this antiendometriosis herbal mixture on cell proliferation, apoptosis, and CCL5 expression and secretion in endometriotic stromal cells in vitro. Isolated normal endometrial, eutopic, and ectopic endometriotic stromal cells were cultured under established conditions. Cell proliferation, apoptosis, and CCL5 gene expression protein secretion was evaluated after incubation with different concentrations of an antiendometriosis herbal mixture extract. Cell proliferation was assessed by cell counting, (3)H-thymidine incorporation, and MTS assays. Apoptosis was determined by blotting using anti-cleaved caspase 3 antibodies and by a TUNEL assay. CCL5 gene expression and protein secretion were determined by transient transfection of gene promoter reporters and ELISAs in cell supernatants. Extracts of a traditional herbal mixture dose-dependently decreased cell proliferation in normal, eutopic, and ectopic endometriotic stromal cells. (3)H-Thymidine uptake and MTS confirmed these findings. The herbal extracts induced apoptosis, as evidenced by activation of caspase 3 and the presence of TUNEL-positive cells after treatment. The herbal extracts also suppressed CCL5 gene transcription and protein secretion in endometriotic stromal cells, even when corrected for cell number. Extracts from a medicinal herbal mixture have direct effects on cell proliferation, apoptosis, and CCL5 production in endometriotic stromal cells. Our findings support the further investigation of novel, potentially safe and well-tolerated botanical products as future endometriosis treatments.

항비만에 대한 생약복합물의 효과

민간요법 중에서 비만 치료에 사용되는 4종의 식물인 지유, 옥발, 적하수오 및 삼백초를 동량으로 혼합하여 10배의 물을 사용하여 가열추출 후 감압농축 하여 HEM을 조제하였고, 이렇게 조제된 HEM을 사용하여 0~100 ㎍/mL 농도로 3T3-L1의 지방축적 억제율을 측정한 결과 농도가 증가함에 따라 유의적으로 증가하였으며, 동일 농도에서 세포독성은 없었다. 또한 지방 축적에 관여하는 효소인 GPDH의 활성을 억제함으로써 세포내 지방이 축적되는 것을 억제하였다. 5주간의 동물실험 결과 대조군과 비교하여 HEM1과 HEM2군 모두 체중 변화와 식이효율이 줄어드는 것으로 나타났으며, 혈액 분석에서 HEM군은 혈중 중성지방과 총콜레스테롤에 효과를 보이지 않았다. 해부학적인 측면에서 부고환 및 신장 주위의 지방무게와 간 무게 또한 낮았다. 이러한 결과를 통해, 본 실험에서 사용한 생약복합물은 항비만 소재로써 체지방 축적억제에 효과성이 있음을 확인하였다.

Protective effects of a compound herbal extract (Tong Xin Luo) on free fatty acid induced endothelial injury: Implications of antioxidant system

BackgroundTong-Xin-Luo (TXL) – a mixture of herbal extracts, has been used in Chinese medicine with established therapeutic efficacy in patients with coronary artery disease.MethodsWe investigated the protective role of TXL extracts on endothelial cells injured by a known risk factor – palmitic acid (PA), which is elevated in metabolic syndrome and associated with cardiovascular complications. Human aortic endothelial cells (HAECs) were preconditioned with TXL extracts before exposed to PA for 24 hours.ResultsWe found that PA (0.5 mM) exposure induced 73% apoptosis in endothelial cells. However, when HAECs were preconditioned with ethanol extracted TXL (100 μg/ml), PA induced only 7% of the endothelial cells into apoptosis. Using antibody-based protein microarray, we found that TXL attenuated PA-induced activation of p38-MAPK stress pathway. To investigate the mechanisms involved in TXL's protective effects, we found that TXL reduced PA-induced intracellular oxidative stress. Through AMPK pathway, TXL restored the intracellular antioxidant system, which was depressed by the PA treatment, with an increased expression of thioredoxin and a decreased expression of the thioredoxin interacting protein.ConclusionIn summary, our study demonstrates that TXL protects endothelial cells from PA-induced injury. This protection is likely mediated by boosting intracellular antioxidant capacity through AMPK pathway, which may account for the therapeutic efficacy in TXL-mediated cardiovascular protection.

Protective and therapeutic effects of an extract mixture of alder tree, labiate herb, milk thistle green bean-rice bran fermentation, and turnip against ethanol-induced toxicity in the rat

An herbal extract mixture and yogurt added to the herbal extract mixture were tested for their protective and therapeutic effects on ethanol-induced liver injury. The herbal extract mixture, yogurt and commercial drugs were used for treatment for two weeks prior to administering a single oral dose of ethanol (3 g/kg body weight). The herbal extract mixture and yogurt added to the herbal extract mixture were found to provide protection against ethanol-induced toxicity comparable to the commercial drug treatment, according to the serum and histopathological analysis. It was also shown that co-treatment with herbal extract mixture and yogurt against a triple oral dose of ethanol (2 g/kg body weight, over one week) provided protection against ethanol toxicity. After the initial set of experiments, the herbal extract mixture and yogurt treatments were extended for three more weeks. When compared to the positive control, further treatment with both the herbal extract and yogurt significantly reduced liver injury and resulted in a lower grade of lipid deposition.
