Background Ayurveda, the Indian system of medicine, has been practised in India since ages. We evaluated the overall awareness regarding Ayurveda among patients attending two specialty clinics at a tertiary care institute. Methods We did a cross-sectional study on patients attending the cardiology and neurology clinics at a tertiary care hospital in India. We conducted this paper-based survey using a standardized, validated questionnaire. Statistical analysis was performed using STATA version 14.2. Results Three hundred and ninety-seven patients agreed to participate in the study. Their mean (SD) age was 45.65 (15.02) years. Among them 68.5% were men and 56.9% were from urban areas. Participants perceived that Ayurveda comprised herbal drugs (77.6%), metallic/herbo-mineral preparations (44.3%), Panchakarma therapy (22.2%) and personalized medicine (37.8%). Principal sources of information were TV promotional programmes (34.7%) and newspaper advertisements (13.9%). Nearly two-thirds (63%) of participants opined that Ayurveda is effective in chronic disorders. Although only 9.1% of participants reported the use of Ayurvedic medicines, 89.2% believed it would be beneficial if the All India Institute of Medical Sciences (AIIMS), New Delhi had Ayurveda services. Three-fourths (75.8%) of respondents were interested to participate in research studies integrating Ayurveda with modern medicine. Conclusion Imprecise knowledge and awareness towards Ayurveda appears to prevail in addition to the low practice among the patients surveyed. We found imprecise knowledge of Ayurvedic therapies and its low usage among patients attending specialized OPDs in a tertiary care hospital. The major source of information reported was promotional advertisements in the print and electronic media. Our survey shows a need for awareness programmes for general public at various levels.
