Background and Objective: Data from researches have shown a rise in disease, ill health and death linked with the utilization of herbal products, thereby raising global awareness in the last few years. On that account, the safety and toxicity evaluations of herbal products and preparations was essential. This study evaluated the toxicological profile of Yagari – a herbal mixture. Materials and Methods: Acute oral toxicity (LD50) was carried out in Swiss mice according to Lorke’s method while sub-chronic toxicity study was carried out with 20 adult albino rats which were divided into 4 groups of 5 animals each. Group one served as control and received normal saline while Groups 2 to 4 received 250, 500 and 1000 mg/kg yagari respectively for 28 days. The body weights of the rats were monitored while on day 29, the rats were sacrificed and blood samples and organs were collected for biochemical/hematological analysis and histopathological examination respectively. Results: Results showed that Yagari is not noxious up to 5000 mg/kg following acute oral toxicity study. The sub-chronic toxicity test divulged that Yagari had no serious end results on the biochemical, hematological and histopathological parameters, although the body weight of the animals significantly increased. Conclusion: It was concluded that Yagari is not toxic, still further investigations on a large number of animals are essentially needed to denote safety and efficacy of the herbal formulation.

Acute oral toxicity of methanol extract of Asiasari radix was evaluated in ICR mice of both sexes. In this study, mice were administrated orally with dosages of 1000, 3000, and 5000 mg/kg body weight of Asiasari radix extract. Mortality, signs of toxicity, body weight, food consumption, and gross findings were observed for 14 days post treatment of Asiasari radix extract. No mortality, signs of toxicity, and abnormalities in gross findings were observed. In addition, no significant differences were noticed in the body and organ weights between the control and treated groups of both sexes. These results show that the methanol extract of Asiasari radix is toxicologically safe by oral administration.

In this study, the extract of Ocimum tenuiflorum was formulated to promote wound healing and no acute toxicity study has been reported on this type of formulation. Acute oral toxicity results of the rats after administration of 5000 mg/kg body weight (BW) formulation showed no toxic effects and behavioural changes of the rats after 14 days of observation. On day 14, the rats were anaesthetized to collect the vital organs for histopathological examination. The microscopy study of the visceral organs of wound healing powder group shows no sign of toxicity in comparison to untreated rats organs. In conclusion, the result of the acute oral toxicity test of wound healing drink showed no sign of toxicity, as corroborated by a histopathological study.

The objective of this study was to evaluate the acute and subacute toxicity (28 days) of the ethanol extract ofZ. zerumbetrhizomes (EEZZ) via the oral route in Wistar rats of both sexes. In the acute toxicity study, Wistar rats were administered a single dose of 15 g kg−1of body weight by gavage, and were monitored for 14 days. EEZZ did not produce any toxic signs or deaths; the 50% lethal dose must be higher than 15 g kg−1. In the subchronic toxicity study, EEZZ was administered by gavage at doses of 1000, 2000 and 3000 mg/kg daily for 4 weeks to Wistar rats. The subacute treatment with EEZZ did not alter either the body weight gain or the food and water consumption. The hematological and biochemical analysis did not show significant differences in any of the parameters examined in female or male groups. Necropsy and histopathological examination, did not reveal any remarkable and treatment related changes. A no-observed adverse-effect level for EEZZ is 3000 mg kg−1for rats under the conditions of this study. Hence, consumption of EEZZ for various medicinal purposes is safe.

Objective: The fundamental reason for this examination was to look at the acute and subchronic toxicity studies of chloroform and methanol extracts of Barleria buxifolia Linn. (Acanthaceae) on creature models according to the OECD rules 407 and 425, respectively. Methods: In acute oral toxicity, study a single oral dosages of 5000 mg/kg body weight of chloroform and methanol extracts was given individually to rats and watched them for 2 weeks for the discovery of acute changes and for its mortality any. During acute oral toxicity study period, no mortality was seen without any signs of intense changes. Further, it was executed the subchronic toxicity of extracts. Barleria buxifolia extracts (chloroform and methanol) were independently given every day at dosages of 250 and 500 mg/kg body weight for 90 days to recognize the progressions any at subchronic poisonousness levels. Towards the finish of the experimentation the serum tests of trail creatures were gathered and watched for any progressions in haematological, biochemical and histopathological boundaries Results: All parameters of treated group were shown unaltered changes throughout the study period when compared with that of normal group. The outcomes propose that the oral organization of chloroform and methanol extracts of Barleria buxifolia did not raise any huge poisonous impacts when contrasted with that of control animals. Conclusion: Hence, the extracts may be safe for therapeutic use and as an alternative system of medicine.

Objectives: The present study was carried out to evaluate the hydroalcoholic extract of Mucuna pruriens (HAMP) seeds for its acute oral toxicity in albino rats. Methods: Acute oral toxicity of MP seed extract was assessed in albino rats with three different doses of the extract with 175, 550, and 2000 mg/ kg body weight. Body weight, mortality, and clinical signs were recorded on 0 (before administration), 7th, and 14th days. Rats were sacrificed after day 14 and observed for any histological changes in the brain, heart, liver, and kidney tissues. Rats were normal up to 1 h and exhibited dullness and piloerection after 1 h which continued up to 2–4 h of observation period on day 0 of administration. All animals appeared normal from day 1 to throughout the experimental procedure. Results: No significant changes in the histological structure of the liver, kidney, and heart were noticed except mild congestion and hydropic changes only in liver tissue seen for 2000 mg/kg body weight of HAMP seeds. The seed extract of MP is non-toxic to rats and did not show any mortality nor the behavioral changes. In addition, it showed an increase in the body weight with the administration up to 2000 mg/kg body weight. Conclusion: MP seed extract signified as neurosuppressant, and the drug can be used in the treatment of neurological disorders characterized by hyperactivity of the neurons. The present data could provide adequate confirmation of the safety of MP for further experimental studies on a standardized formulation of the seeds extract.

Abstract Objectives Madhulai Manappagu – a well-known sastric and widely prescribed Siddha herbal syrup formulation indicated for treating Veluppu Noi (Anaemia especially Iron deficiency Anaemia) has been in day today practice in Tamil Nadu for a quite longer decades. The syrup is a herbal preparation which has a sweet pleasant odour and a palatable taste, contain the juice of pomegranate (Punica granatum L.) as the main ingredient. Though the formulation is a fruit juice, the safety profile of the syrup is not established and is being marketed without toxicological evaluation. The study is aimed at ascertaining the acute and sub-acute toxicity assessment of Madhulai Manappagu in Wistar Albino rats. Methods The acute and sub-acute (28day repeated oral) toxicity studies were performed as per the guidelines mentioned in the Organization for Economic Cooperation and Development (OECD) 423 (adopted on December 2001) and TG 407 (adopted on October 2008) with slight modifications respectively. For acute toxicity study, three female rats were randomly selected as control; three female rats were randomly selected and were administered a single dose of 5,000 mg/kg body weight per oral route. For sub-acute (28day repeated oral) toxicity studies, three doses of test drug MM of 500 mg/kg/day (low dose), 750 mg/kg/day (intermittent dose) and 1,000 mg/kg/day (high dose) were selected for administration. Both sexes of Wistar Albino rats were randomized into four groups of 10 animals each (five males, five females). Group I was kept as control group. Group II, III and IV served as low, intermittent and high doses of MM respectively. Animals were observed for mortality, morbidity, body weight changes, feed and water intake. Haematology, clinical biochemistry, electrolytes, gross pathology, relative organ weight and histopathological examination were performed. Results In the acute toxicity study, rats showed no toxicological signs on behavior, gross pathology and body weight of rats when treated with a single dose of 5,000 mg/kg body weight per oral route. In the subacute (28 days repeated oral) toxicity study, rats have showed no significant changes on behavior, gross pathology, body weight, and hematological and biochemical parameters when treated with Madhulai Manappagu in three different doses. Conclusions The toxicity studies which include both acute and 28 days repeated (subacute) oral toxicity studies, revealed no observed adverse effect level (NOAEL) of Madhulai Manappagu in animals. Thus the safety of the drug in human usage was ensured.
