: Irritable bowel syndrome (IBS) is a functional gastrointestinal condition characterised by stomach pain, discomfort, and changes in bowel patterns in absence of organic disorder. Grahani roga is mentioned in classical ayurvedic texts which can be correlated with IBS. The current study seeks to prepare and standardise Kutaj parpati, as well as conduct a pilot study to evaluate its efficacy in Grahani roga (IBS) patients. Assessment of the influence of kutaj parpati on patient-related attributes is challenging because to non-standardized methods of preparation, and this study intends to address this gap. Materials and Methods: The kutaj parpati was prepared in Rasa shashtra and Bhaishajya kalpana department of ayurvedic Medical college.The standardization was done according to ancient ayurvedic parameters. The total loss during preparation of kutaj parpati was 12 grams. The reasons for loss might be ignition leading to oxidiation.The same kutaj parpati was used in Grahani roga (Irritable bowel syndrome) patients who satisfied inclusion criteria. The symptoms of the patients were assessed on a numeric rating scale and the changes in parameters were noted and analysed. Results : The physiochemical characteristics of kutaj parpati were noted and it as it was brownish black in colour and passed all ayurvedic tests for standaedization mentioned in classical texts.Total 4 patients participated in study, who took kutaj parpati as a monotherapy.Base line symptomatoloy of the patient ranged from NRS of 6 to 7 and it reduced to 4 to 5 after 3 months of continuous monotherapy of kutaj parpati.All parameters observed showed reduction in symptom severity after kutaj parpati monotherapy. Conclusion: Ayurvedic principles were followed in the manufacturing of kutaj parpati, including raw material standardisation, process standardisation, and final product standardisation. The same Kutaj parpati was administered on grahani roga patients which was shown to be favourable in terms of the metrics investigated. To corroborate the findings, more research with a larger sample size is required
