Abstract Qing Hao Gan Cao (QHGC), a Chinese medicinal formula containing Artemisia annua and Glycyrrhizae Radix et Rhizoma, has been used to treat sunstroke and as an antiviral agent for more than 800 years. It has not previously been subject to a toxicological safety evaluation in acute and subacute (28 days) studies. Therefore, the acute and subacute toxicity of an aqueous extract of QHGC were evaluated in vivo. For the QHGC preparation, the botanical raw materials were crushed into pieces and mixed in the ratio of 10:1 in distilled water for 12 h, then boiling three times for 2 h each time. The three decoctions were mixed and filtered, then spray-dried with hot air at 160°C for 30 min, and stored at room temperature. For the acute toxicity test, 72.0 g/kg of QHGC extract was administered by gavage to male and female mice. Body weight, general observations, and autopsy results were recorded. No mortality or toxicity signs were observed during the studies. For the subacute toxicity test, 4.0, 8.0, or 16.0 g/kg/day of QHGC extract was administered to rats for 28 days. General observations and mortality, body weight, biochemical and hematological parameters, organ weight, and pathological morphology were analyzed. The acute and subacute toxicity studies did not show significant changes in body weight, general observations, hematology and biochemical parameters, organ weight, and liver, spleen, stomach, duodenum, testis, ovary, lung, heart, and kidney histopathological analyses. The consumption of QHGC aqueous extract can be considered safe within the conditions of this study.

Context. Nigella sativa seeds are usually used as traditional medicine for a wide range of therapeutic purposes. Objective. To investigate the subacute toxicity of NS aqueous extract and select its lowest dose to study its antidiabetic effect. Methods. 5 AqE.NS doses (2, 6.4, 21, 33, and 60 g/Kg) were daily administered to mice by gavage. Biochemical parameters measurements and histological study of the liver and the kidney were performed after 6 weeks of supplementation. Thereafter, and after inducing diabetes by alloxan, rats were treated by 2 g/Kg of AqE.NS during 8 weeks. Metabolic parameters were measured on sera. A horizontal electrophoresis of plasmatic lipoprotein was conducted. Glycogen, total lipids, and triglycerides were measured in the liver. TBARS were evaluated on adipose tissue, liver, and pancreas. Results. AqE.NS showed no variation in urea and albumin at the 5 doses, but hepatotoxicity from 21 g/Kg was confirmed by histopathological observations of the liver. In diabetic rats, AqE.NS significantly decreased glycemia, TG, T-cholesterol, LDL-c, and TBARS and showed a restored insulinemia and a significant increase in HDL-c. Results on the liver indicated a decrease in lipids and a possible glycogenogenesis. Conclusion. AqE.NS showed its safety at low doses and its evident antihyperglycemic, antihyperlipidemic, and antioxidant effect.

Histopathological Studies

The toxic effects of an aqueous extract of Abrus precatorius were studied in 20 male white rats over a period of 18 days. The rats were divided into four groups of five rats per group. Those in Group A served as controls while the rats in Groups B, C and D were dosed per os with 400 mg/kg, 800 mg/kg and 1 600 mg/kg of the extract, respectively. Blood samples were collected for haematological and biochemical analysis and specimens of the liver, kidney and testes were taken for histopathological studies. The study showed that the extract of A. precatorius caused decreased levels of packed cell volume, haemoglobin concentration, red blood cell count, white blood cell count, mean corpuscular volume and mean corpuscular haemoglobin. The extract also resulted in increased levels of total serum protein, albumin, alanine amino transaminase, aspartate amino transferase, alkaline phosphatase and total bilirubin. Histologically, testicular degeneration characterized by decreased numbers of lining cells of the epithelium as well as reduction in sperm cells with presence of scattered Sertoli cells were noted. The study thus showed that aqueous extract of Abrus precatorius is toxic and caution should be exercised in its use for medicinal purpose.

The present study is a contribution to the enhancement of Ivorian traditional medicine, by carrying out bio-tolerance tests of an aqueous extract of the aerial parts of Crotalaria retusa (EACr) in mice and rats according to the guidelines of the Organization for Economic Co-operation and Development (OECD) 423 and 407, respectively. The doses of 2000 and 5000 mg/kg of body weight (BW) of the extract were used for acute toxicity. For subacute toxicity which lasted 28 days, doses of 500, 1000, and 2000 mg/kg BW have been used. The administration of the single doses of 2000 and 5000 mg/kg BW of EACr did not provoke death in female mice in the acute toxicity setting. For subacute toxicity in rats (male and female), the administration of repetitive doses of 500, 1000, and 2000 mg/kg BW of EACr over a period of 28 days did not cause death in these animals. In females, these doses caused weight loss and a decrease in platelets. The extract reduced the activity of AST in both sexes of rats. The findings also showed that this extract would possess a nephroprotective property in male and female rats. Keywords: Crotalaria retusa, Acute and subacute toxicities, Wistar rat, Swiss mice

Subacute Toxicity

Ethnopharmacological Relevance. Haloxylon scoparium Pomel is a herbal medicine traditionally used for treating scorpions and snakebite, diabetes, and stomachache as well as several other diseases. No systematic study of the potential toxicity of the plant has been described. Aim of the Study. The current study is aimed at assessing the potential toxicity of Haloxylon scoparium Pomel through the acute and subacute toxicity tests. Materials and Methods. Acute toxicity test was performed on Swiss albino mice at a single oral dose of 1-10 g/kg for 14 consecutive days. General behavioral adverse effects, mortality, and latency of mortality were determined. In the subacute study, the Haloxylon scoparium Pomel extract was administered orally at doses of 500, 1000, and 2000 mg/kg daily for 30 days to Wistar rats. Body weight and selected biochemical and hematological parameters were determined at the end of the experiment. Sections of livers and kidneys were removed for histological studies. Results. Acute toxicity study showed that the oral LD50 value of Haloxylon scoparium Pomel extract was 5000 mg/kg. The subacute toxicity study of Haloxylon scoparium Pomel extract at doses 500, 1000, and 2000 mg/kg did not produce any observable symptoms of toxicity and no significant variation in body weight, organ weights, food, and water consumption or mortality in all treated rats. However, the administration of the Haloxylon scoparium Pomel extract to rats at 500 mg/kg and 1000 mg/kg showed a significant decrease in platelets. Moreover, only at the highest dose (2000 mg/kg), the extract caused a significant increase in red blood cells and hemoglobin. Our results showed that subacute treatments with Haloxylon scoparium Pomel extract at doses of 1000 mg/kg and 2000 mg/kg significantly elevated alkaline phosphatase and triglycerides. Histological studies showed that the subacute treatments of rats with Haloxylon scoparium Pomel extracts, at the doses 1000 and 2000 mg/kg, induced some histopathological changes in the livers but a slight changing in kidneys. Conclusion. Our results indicated low acute toxicity of the aqueous extract of Haloxylon scoparium Pomel. Furthermore, daily oral administration of Haloxylon scoparium Pomel extract caused some damages to the livers of rats treated with high doses, expressed by an increase in some enzyme activities such as ALP. Regarding the renal function, we did not find remarkable toxicity in the subacute treatment with Haloxylon scoparium Pomel extracts at doses 1000 and 2000 mg/kg. However, further toxicity assessments should be done to ascertain the safety or the toxicity of this valuable plant species “Haloxylon scoparium pomel” in subchronic treatments.

Jatropha curcas is a medicinal plant whose dead leaves are particularly used in arterial hypertension and diabetes treatment. The purpose of this study is to conduct an acute and subacute toxicity study of Jatropha curcas leaves aqueous extract (JCLAE) using OECD method. For acute toxicity, dose limits of 2000 and 5000 mg/kg were used. In subacute toxicity study 4 batches were constituted including a control batch that received distilled water for 28 days and the other 3 batches, JCLAE doses of respectively 200, 400, 800 mg/kg for the same duration. The LD50 was determined and the hematological, biochemical and histological parameters were analyzed in mice. The LD50 is greater than 5000 mg/kg. HDL-C is the only biochemical parameter that has experienced significant rise variation. Hematological analysis showed a decrease in mean platelet volume and Platelets number. The histological study revealed cases of hepatic cellular apoptosis and kidneys tubular necrosis among animals treated with highest dose. JCLAE is less toxic than Jatropha curcas leaves aqueous extract and high-dose JCLAE also has a moderate toxic effect on thrombocyte line and a protective effect on cardiovascular system.

Background: Leaves of Gymnosporia spinosa have been used by people for treatment of jaundice. Traditional herbal drugs are popular all over the world and it is presumed that herbal medicines have lesser or no side effects. This generalized belief and no information available regarding toxicity study of G. spinosa with search from limited available information prompted us to carry out work on subacute toxicity study of aqueous extract of dried leaves of G. spinosa.Methods: Subacute toxicity study was carried out using aqueous extract of G. spinosa leaves. 30 rats of either sex were randomly divided in to 4 groups. First group received distilled water (control). Second, third and fourth groups received single daily dose of drug orally as 40, 120 and 240 mg/100 g of body weight respectively for 3 weeks. Animals were observed for various parameters. After 21 days blood was collected for blood counts and biochemical parameters. Liver, lungs and kidney were subjected to histo-pathological studies.Results: Throughout study there was no mortality in any group. Degenerative changes in the liver. Other organ does not show any changes. Analysis of biochemical data showed serum glutamic pyruvic transaminase and s. alkaline phosphatase levels were decreased. Serum bilirubine, blood urea and serum creatinine level were increased significantly.Conclusions: The data showed that there was hepato-renal toxicity at higher dose level which is about 100x human therapeutic dose.
