Abstract
Combretaceae are reported in the literature for presenting neuroprotective and anxiolytic effects in animal models. Combretum lanceolatum Pohl. has few scientific reports on its pharmacological effects. The aim of this study was to evaluate the anxiolytic and anticonvulsant effects of the ethanol extract from the leaves of C. lanceolatum Pohl. (EtFoCl) and its possible mechanism of GABAergic action in adult zebrafish. EtFoCl was subjected to determination of the total phenol concentration, identification of phytochemical flavonoids by HPLC and in vitro antioxidant activity test, open field test and 96-hour acute toxicity in zebrafish. Anxiolytic doses were tested for pentylenetetrazole-induced seizures in adult zebrafish. To study the mechanisms of action, molecular docking simulations were performed between the main phytochemicals and the GABAA receptor (anxiolytic activity) and carbonic anhydrase II (anticonvulsant). The non-toxic doses that caused motor impairment were assessed in acute and chronic anxiety using the light and dark test. EtFoCl had altered the animals' locomotion, presenting an effect similar to the anxiolytic and anticonvulsant. These effects were prevented with flumazenil (GABAA antagonist). The phytochemicals homoorientin and quercetin-3-O-galactoside coupling in a region close to that of the inhibitor diazepam (GABAA receptor). Regarding the anticonvulsant mechanism, Homoorientina and Isovitexina were identified as the most favorable for the complex form with the carbonic anhydrase enzyme. C. lanceolatum has pharmacological potential for the treatment of acute and chronic anxiety and seizures, which can be partially explained by an interaction with the GABAA receptor.Communicated by Ramaswamy H.

Safety evaluation of Bon-santé cleanser ® polyherbal in male Wistar rats: Further investigations on androgenic and toxicological profile. J Tradit Complement Med 2018; 8:212-219. [PMID: 29322011 PMCID: PMC5756022 DOI: 10.1016/j.jtcme.2017.06.002] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2017] [Revised: 05/21/2017] [Accepted: 06/08/2017] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND The global increase in acceptance and use of herbal remedies in recent times is still accompanied with poor knowledge of their potential adverse effects and the toxicological implications of their use are underestimated. METHODS Bon-santé Cleanser® (BSC), a polyherbal containing Anogeissus leiocarpus, Terminalia ivorensis, Massularia acuminate and Macuna pruriens, is an "energizer and hormone booster". We assessed the effect of BSC on reproductive function after administration for 60 days in male Wistar rats. Rats (150-300 g) were assigned into four groups of 8/group. Control received distilled water (10 ml/kg) while other groups received BSC 250, 500 and 1000 mg/kg/day p.o. respectively. Animals were euthanized by cervical dislocation and samples collected for analysis. RESULTS BSC (250 mg/kg) elevated (p < 0.05) follicle stimulating hormone and luteinizing hormone levels respectively. BSC decreased sperm motility and the live-dead ratio at 1000 mg/kg and reduced reproductive hormone at 500 mg/kg and 1000 mg/kg respectively. BSC at 500 mg/kg increased (p < 0.05, F = 3.18-13.21) testicular reduced glutathione level (50.3%) and catalase (43.7%) but not activities of superoxide dismutase, glutathione S-transferase, and malondialdehyde level. Further, BSC influenced Mg, Zn, Cu, P, Mn, Ni and Fe levels (p < 0.05). BSC (1000 mg/kg) decreased testis weight (p < 0.05) and induced mild inflammation characterized by atrophic tubules. CONCLUSION Overall, our data suggest BSC at low doses may increase reproductive hormones regulated by FSH and LH as observed in this study. However, BSC administration should be done with caution as it may induce reproductive toxicity in large doses.

Abstract
BACKGROUND The potential harm of medicinal herbs has been recently observed following herbal toxicity studies after ingestion of polyherbal remedies. This was the rationale for the food and drug regulatory agency decision for thorough safety evaluation of herbal medicines. Androgenic, antipyretic, analgesic and anti-inflammatory potentials as well as chemical compositions of extracts of massularia acuminata, terminalia ivorensis, anogeissus leiocarpus and macuna pruriens respectively have been documented. Thus, Bon-santé cleanser® (BSC) is formulated from these medicinal plants with the intention to boost body hormones and energizes the body. Considering the wide usage of BSC, we investigated on its safety in male Wistar rats. METHODS Thirty-two male Wistar rats weighing 201.9 ± 7.5 g were grouped into four treatment groups of eight per group. Group I, (control) received distilled water (10 ml/kg). Groups II-IV received 250 mg/kg, 500 mg/kg and 1000 mg/kg of BSC per oral respectively. Each group was treated for sixty days. RESULTS Acute toxicity test, in male Wistar albino mice, showed that LD50 was 600 mg/kg via i.p. while 4 g/kg was nonlethal after oral administration in mice. Hepatic and renal biomarker enzymes were unaltered in all rats. Increased in PCV (p <0.05) was observed at 500 mg/kg. BSC modulates antioxidants biomarkers following sub-chronic administration and increased serum Na(+) (p >0.05). BSC at 1000 mg/kg caused mild inflammation of the liver and heart but not kidneys histologically. CONCLUSIONS BSC has been found to be relatively safe in Wistar rats. Although, our findings indicate that herbal therapy with BSC should be done with caution as a mild alteration in the liver and heart architectures were observed.
