Ruzu bitters black for men (RBBM) is a polyherbal product widely used amongst men in Nigeria to enhance libido, rejuvenate male organs and to manage erectile dysfunctions, prostate anomalies, weak erection, and premature ejaculation. This study was carried out to investigate the toxicological effect from the use of herbal product. Acute toxicity test of RBBM on rats was carried out in two phases; 10 mg/kg, 100 mg/kg and 1000 mg/kg for phase I and 1600mg/kg, 2900 mg/kg and 5000 mg/kg for phase II, were administered respectively. For sub-acute toxicity, two groups of 5 animals each received RBBM (0.87 mg/kg and1.17 mg/kg respectively) and a third group received water orally for 28 days. The study analyzed the median lethal dosage, and sperm morphology, sperm motility, sperm count, sperm viability and histology of the testes as indices for sub-acute toxicity. No death was recorded for the acute and sub-acute studies but there was a moderate physical sign of toxicity. In the sub-acute toxicity study, there was a significant increase (p˂0.05) in testicular weight of Group 1 animals. Also, sperm count, and sperm motility increases significantly (p˂0.05) while there was a decrease in multiple tail sperm across the test groups. RBBM is not toxic to sperm morphology and causes no death at 5000 mg/kg in male albino Wistar rats.

Diabetes mellitus is a complex multifarious metabolic disorder characterized by chronic hyperglycemia that requires non-stop treatment with multiple factors that will reduce the risk of long-term complications and drug side effects. Streptozotocin is well known for its selective pancreatic islet β-cell cytotoxicity used to induce diabetes mellitus in animals. It also interferes with cellular metabolic oxidative mechanisms. Phytomedicine has been in existence since the primitive age and has proven to be effective in treating this condition. This study was aimed at evaluating the effect of Gangaria de flush (Gdf) herbal mixture on lipid profile in streptozotocin (STZ) (60mg/kg) induced diabetic rat. The diabetic rats were treated with Gangaria de flush (0.3ml/kg body weight) and Glibenclamide (5mg/kg body weight) for 7days. The effects of both Gangaria de flush herbal mixture and glibenclamide were analyzed. Gangaria de flush showed a reduction in the lipid profile with a significant percentage reduction of 45.9% for the total cholesterol, 65.7% for the total triglyceride, 63.5% for the low-density lipoprotein, 65.8% for the very low-density lipoprotein as against the negative control and a 7.6% significant increase in the high density lipoprotein. Gangaria de flush showed a significant (p<0.05) positive effect on the lipid profile. Hence, it can be suggested that Gangaria de flush herbal mixture has a significant effect in maintaining the lipid level.
