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.

Hydroethanolic Extract

This toxicological assessment evaluated the safety of a hydroethanolic extract prepared from Caralluma fimbriata (CFE), a dietary supplement marketed worldwide as an appetite suppressant. Studies included 2 in vitro genotoxicity assays, a repeated dose oral toxicity study, and a developmental study in rats. No evidence of in vitro mutagenicity or clastogenicity surfaced in the in vitro studies at concentrations up to 5000 μg of extract/plate (Ames test) or 5000 μg of extract/mL (chromosomal aberration test). No deaths or treatment-related toxicity were seen in the 6-month chronic oral toxicity study in Sprague-Dawley rats conducted at 3 doses (100, 300, and 1000 mg/kg body weight (bw)/d). The no observed effect level for CFE in this study was considered to be 1000 mg/kg bw/d. A prenatal developmental toxicity study conducted at 3 doses (250, 500, and 1000 mg/kg bw/d) in female Sprague-Dawley rats resulted in no treatment-related external, visceral, or skeletal fetal abnormalities, and no treatment-related maternal or pregnancy alterations were seen at and up to the maximum dose tested. CFE was not associated with any toxicity or adverse events.
