Introduction: Immunomodulators are molecules of synthetic or biological origin that help to regulate the immune system. Many studies have focuses on exploring for phytochemical compounds that used as immunomodulatory properties in Indonesia, as well as in Sulawesi. The immunomodulatory activity of rhizome extract of E. flexuosa, an endemic flowering plant of Sulawesi on male mice were studied. Methods: 25 male mice (Mus musculus) used were randomly divided into 5 groups and Staphylococcus aureus (ATCC 25923) was used as inducer. The negative control group was given 0.5\% Na-CMC (Carboxymethyl Cellulosa Sodium), positive control group was given stimuno{\textregistered} and treatment groups were an ethanol extract of E. flexuosa with successive doses of 200, 400 and 800 mg/kg body weight (BW) respectively. Each group was given the preparation orally for 7 days and on the 8th day the test animals were induced by Staphylococcus aureus bacteria intraperitoneally. The mice were dissected and the peritoneal fluid was taken to determine the activity of the macrophage cells. Meanwhile, Thomson and Weil method was used to study the acute toxicity test and determine the lethal dose 50 (LD50). Results: The percentage of macrophage activity in each group of negative control, positive control, extract doses of 200, 400 and 800 mg/kg BW respectively were 40.40\%, 82.65\%, 53.05\%, 69.38\% and 82.06\%. Based on the results obtained, it was shown that the E. flexuosa rhizome extract has an optimum dose of 800 mg/kg BW, which was not significantly different from the positive control. Meanwhile, the symptoms of toxicity began to appear from a dose of 600 mg/kg BW to a dose of 2400 mg/kg BW including decreased motor activity, tremor, ataxia, lids and writhing. LD50 expressed in LD50 within the criteria of being practically non-toxic. Conclusions: The E. flexuosa rhizome ethanolic extract showed the immunomodulatory activity at optimum dose of 800 mg/kg BW by the increasing of macrophage phagocytosis activity. Moreover, the extract was also practically non-toxic based on LD50 value.

Background: Plant based products are recognised as sources of drugs for treatment of diseases. Objective: The study aimed at predicting the physicochemical, pharmacokinetics, drug-likeness and toxicity of the compounds identified from the methanolic Encephalartos ferox fruit extract. Methods: The physicochemical, pharmacokinetics properties and bioactive scores of the compounds were predicted using SwissADME and Molinspiration computational tools. Drug-likeness of the compounds was evaluated based on the Lipinski rule of five (Ro5). In silico mutagenicity, carcinogenicity and inhibition of human ether-a-go-go-related (hERG) gene were also investigated using PreADMET web tool. Results: The physicochemical properties showed the compounds, except 9-Octadecenoic acid, 1, 2, 3-propanetriyl ester to adhere to Ro5. The evaluation of their inhibitory effects profile in several cytochrome P450 isoforms indicate that all the compounds are not the inhibitors of CYP2C19 and CYP3A4 whereas some inhibited CYP1A2, CYP2C9 and CYP2D6. The drug-likeness evaluation employed Ro5 as a filter and all compounds complied with it except for 9-Octadecenoic acid, 1, 2, 3-propanetriyl ester. About 50\% of the tested compound were found to be safe as they did not exhibit antimutagenic and carcinogenic effects. Moreover, the risk of inhibition of hERG gene revealed to be low to medium risk depending on the compound. Conclusion: The calculated physicochemical and pharmacokinetic properties suggest that most of the compounds are safe and have promising oral bioavailability.

Background: Ephedra sinica (ES) (Ma-huang) is a well-known plant due to its widespread therapeutic uses. However, many adverse effects such as hepatitis, nephritises, and cardiovascular toxicity have been reported for this plant. Few of these side effects are reversible whereas others are irreversible and may even lead to death. Aim of the Study: The aim of this study was to investigate the clinical uses and toxicity cases/consequences associated with the use of ES. The review will compare and evaluate the cases reported for ES and identify the causes which make the plant a poisonous one. Materials and Methods: An extensive literature review was conducted from 2004 to 2017, and research literature regarding the clinical cases were collected using databases and books such as Google Scholar, Science Direct, Research gate, PubMed, and Web of Science/Thomson Reuters whereas the keywords searched were {\textquotedblleft}Ephedra sinica,{\textquotedblright} clinical cases of Ephedra sinica, {\textquotedblleft}Ma-hung poisonous,{\textquotedblright} {\textquotedblleft}Ma-hung toxicity reported cases and treatment,{\textquotedblright} and {\textquotedblleft}Ephedra Sinica toxicity reported cases and treatment.{\textquotedblright} Results: eleven different cases were identified which met the eligibility criteria and were studied in detail to extract out the findings. It turned out that most of the patients and participants developed adverse side effects following the use of ES, and after a proper course of treatment or trail, some of the side effects were reversible, whereas others were found irreversible. The most common adverse effects and toxicity observed in patients were liver problems, renal failures, and cardiac toxicity which resulted in two mortalities whereas the other two got recovered. On an in-depth study, it was revealed that most of the toxicities in such cases were associated with the use of ES in combination with other conventional drugs, long-term use, or use in patients with cardiac and renal problems without a medical supervision. Conclusion: Hence, it is concluded that ES may have reversible as well as irreversible adverse effects and may even result in death; however, the use of a plant with the proper knowledge and under sound medical supervision may reduce such exaggerations

Methods: The extract was administrated orally in four different concentrations: 180, 360, 720, 1440 mg/Kg for ten days, at the 11th day a single dose of NaF was administrated via intraperitoneal at 20 mg/Kg. The genotoxicity study was made with mice from the strain BALB/c, using the Micronucleus test on bone marrow and the Comet assay on peripheral blood according the OECD guides 474 and 489 respectively. The statistical analysis was made by the media{\textquoteright}s analysis with ANOVA. Results: Significant differences were found in Micronucleus frequency between the highest concentrations of Eryngium foetidum and NaF. The Comet assay showed significant reduction in NaF induced damage according to different concentrations of the extract. Conclusion: The Eryngium foetidum extract has cytoprotective activity against oxidant substances such as NaF.

Background: The present day life style causing different illness including liver diseases and different health complications. So, there is a need to identify new chemical entities with more efficiency in the treatment of diseases and less side effects. There were many reports in recent times, about identifying new drugs from different medicinal plants and also precursors for synthesis new bioactive molecules for treating various diseases. Objective: The present study was carried out on root parts (rhizomes) of S. officinalis for phytochemical analysis and hepatoprotective activity on Paracetamol-induced liver toxicity. Materials and Methods: The phytochemical analysis was carried out to know biological active compounds in different extracts of S. officinalis using standard procedures and quantified the total alkaloid and phenolic contents. Hepatoprotective activity of the S. officinalis extracts were carried out by using Paracetamol-induced hepatotoxicity in rats. Results: The phytochemical analysis of S. officinalis roots\’ extracts showed presence of sterols, terpenoids, glycosides, carbohydrates, proteins, flavanoids, alkaloids, phenols, tannins and absence of saponins and oils. The methanolic extract showed more phenolic and alkaloid contents on their quantification. The S. officinalis roots extracts are found to be safe at 2000 mg/kg b. w. in acute toxicity study and showed dose dependent percentage protection on liver toxicity. Methanol extract showed more activity at 500mg/kg b. w. and is comparable with standard drug Liv 52 on altered liver biomarker enzymes AST (SGOT), ALT (SGPT), ALP, total bilirubin and total protein with percentage protection 56.17\%, 54.53\%, 61.55\% 57.29\% and 53.66\%. Conclusion: The present study results indicates that phytochemical constituent\’s diversity in S. officinalis and those extracts possess hepatoprotective activity.

Background: Scaevola spinescens was traditionally used by Australian Aborigines to treat a variety of conditions including bacterial and viral infections, inflammation and cancer. Conventional antibiotics are amongst the most commonly prescribed groups of drugs in allopathic medicine. Therefore, these therapies may be used concurrently by practitioners of complementary medicine and there is a need to evaluate their effects in combination. Methods: Plant extracts were prepared using solvents of varying polarity and subjected to qualitative phytochemical screening analysis. Antimicrobial activity was assessed using disc diffusion and liquid dilution minimum inhibitory concentration (MIC) assays against a panel of pathogenic triggers of some autoimmune diseases. Interactions between the S. spinescens extracts and conventional antibiotics were studied and classified by determining the sum of the fractional inhibitory concentration (\ΣFIC). Synergistic interactions were further examined across a range of ratios using isobolograms analysis. The toxicity of the individual samples and of the combinations was assessed using the Artemia lethality assay (ALA) and an MTS HDF cell viability assays. Results: Methanolic, aqueous and ethyl acetate extracts showed moderate to good inhibitory activity against several bacterial pathogens known to trigger autoimmune inflammatory diseases in genetically susceptible individuals. However, combinations of the methanolic, aqueous, ethyl acetate and hexane extracts with conventional antibiotics proved significantly more effective in inhibiting the growth of Klebsiellia pneumoniae and Streptococcus pyogenes (bacterial triggers of ankylosing spondylitis and rheumatic fever respectively). In total, 4 combinations proved to be synergistic, all of which contained tetracycline as the conventional antibiotic component. Furthermore, all conventional antibiotics and S. spinescens leaf extracts were determined to be nontoxic when tested alone in the Artemia nauplii and HDF bioassays. Combining the extracts and antibiotics did not significantly affect the toxicity of the combinations. Conclusion: S. spinescens extracts were effective inhibitors of the growth of several bacterial triggers of autoimmune inflammatory diseases when tested alone. Additionally, the methanolic, aqueous and ethyl acetate extracts potentiated the activity of tetracycline against bacterial otherwise resistant to its actions. Isolation of the synergising compounds in these extracts may be beneficial in drug design against several bacteria including the microbial triggers of ankylosing spondylitis and rheumatic fever.

Background: In Algeria, the cosmetic market is competitive, with an annual growth of 12\%. Because of the toxicity of synthetics cosmetics, the industry is currently more concentrated on herbal cosmetics. Phytocosmetic is an important aspect of traditional medicine in Algerian culture, whose information is scanty. Objective: The present study has been conducted to assess quantitatively the use of herbs in phytocosmetics application. Method: Data was collected from 300 users via face to face interviews using semi-structured questionnaire in three districts from North-eastern Algeria: Annaba, El Tarf and Skikda. Five parameters were evaluated including the demographic characteristics, the form of cosmetic preparation and, medicinal stories used in cosmetic applications. Results: The soap (67\%) and a fixed oil (56\%) were the preparation forms most used in phytocosmetics applications. Although, five medicinal plants were recorded: Aloe vera (L.) Burm.F., Matricaria recutita L., Lavandula angustifolia Mill., Citrus limon (L.) Osbeck and Ricinus communis L. The highest relative citation frequency (RFC) was attributed to A. vera in the three district Skikda (0.68), Annaba (0.57), and El Tarf (0.43). Eleven traditional recipes have been described. Conclusion: This study is able to record the available information the importance of phytocosmetic in traditional medicine. However, further research should be conducted in Algeria, to explore the toxicity of these products.

Aim: The present study aimed to investigate toxicity and oral glucose tolerance test (OGTT) of Phyllanthus acidus leaf extract (PAE) on Wistar rat. Methods: PAE was prepared and administered orally to experimental animals used. The extract was tested for toxicity in rats at a dose of 0, 1,000, 1,500 and 2,000 mg/kg body weight p.o once daily for 14 days. The hypoglycemic effects of PAE on normal rats and orally glucose-induced hyperglycemic rats were compared with distilled water and glibenclamide. A single dose (250 mg/kg body weight) of PAE was administered and blood glucose level was obtained by pricking the tail vain using glucometer at time -30, 0, 30, 60, 120 and 240 minutes. Results: All doses of the extract did not exert any sign or symptom of toxicity and the dead rat was not found. The body weight, white blood cell (WBC), mean corpuscular volume (MCV), platelet (PLT), plateletcrit (PCT), mean platelet volume (MPV), platelet distribution width (PDW), blood chemistry, blood urea nitrogen (BUN), creatinine, alkaling phosphatase (ALP) and organ weight of liver were not significantly different between control and treated rats. However, red blood cell (RBC), hematocrit (HCT), lymphocyte (LYM), and hemoglobin (Hb) at a dose 1,500 mg./kg body weight were significantly lower than those in the control group. The blood glucose levels of PAE treated groups were not different with control and Glybenclamide treated. Conclusion: The findings of the present study can be concluded that the PAE are practically non-toxic at a lower dose.
