It has an edible aromatic flavor used for food as an appetizer. The ethanolic extracts of Hyptis suaveolens is thereby evaluated to access it effect on albino rats. This is the aim of the study. Martials and Methods: The albino rats were divided into five groups, B, C,D,E of 10 rats per group while group A is the Control. Doses of 100 mg/kg, 200 mg/kg, 400 mg/kg and 800 mg/kg of ethanolic extracts of Hyptis suaveolens administered orally consecutively for 14 days to rats group B,C,D and E while rats in group A were administered water and served as Control group which was later sacrificed. Blood samples were collected for haematological analysis and also serum biochemical tests respectively. The following blood analysis were investigated from the albino rats. Packed Cell Volume (PCV) White Blood Cell (WBC) Red Blood Cell (RBC), differential leucocyte count. The red cell indices such as Mean Cell Haemoglobin Concentration (MCHC) Mean Cell Haemoglobin (MCH) and Mean Cell Volume (MCV) by calculating their absolute value. The serum biochemical parameters was carried out. Serum albumin, serum protein, alkaline phosphatase etc. using Randox, United Kingdom commercially purchased kits with Spectrophotometer for reading the absorbance. Conclusion: lntroduction of ethanolic extracts of Hyptis suaveolens into the albino rats was well tolerated from the study. lt therefore showed that the extracts is safe for administration orally and can be utilized and exploited for further novel research use.
