Ayurveda is a goldmine for researchers. Unfortunately, very few researches are planned with a comprehensive approach. Animals have been used repeatedly throughout the history of biomedical research analysis. The utilization of non-human animals in biomedical research has made an essential contribution from precedent days. These animal experiments advance understanding of anatomy, physiology, pathology, pharmacology, and various medical fields. However, natural laboratory-based new research is

... ill awaited. Our objective was to compile the most recent data on animal study's needs, scope and limitations. Also, we tend to overlook how we conduct a department-wise animal study, the ethics of the animal study, and the similarities between animals and man and their unique mechanisms. We conduct a narrative review. There is a need and scope for animal study in medical bioscience because a cure for a disease proves the safety and efficacy of new treatments attained through animal testing. There are also some limitations in animal studies, like loss of biological variability or predictivity from the utilization of inbred strains, young animals, restriction to single sexes, and inadequate cluster sizes. Also, there are so many department-wise uses and limitations of animal study. Conclusion: Animal study proves beneficial for the future because animals are often used in medical research to investigate the progression of the disease, test new drugs, surgeries, etc. But before that, we must always study the ethics of animal research to avoid unskilled, pseudoscientific and needlessly repetitive studies that bring on reserve damage to laboratory animals.
