Introduction: Laghu Malini Vasanta (LMV) Rasa is a well-known Vasanta Kalpa (formulation). As per reference of Yoga Ratnakara, Rasaka and Maricha are chief ingredients in 2:1 proportion. Bhavana (levigation) is said to be given first with Navaneeta (freshly prepared cow's butter) and then with Nimbu Swarasa (lemon juice) until Ghrita Vimukta stage is reached. Quantity of Bhavana Dravya (levigating media) and duration of levigation are not mentioned. Aims: To develop standard manufacturing procedure of LMV Rasa. Materials and Methods: The study was carried out in two stages - preparation of Yashada Bhasma and preparation of LMV Rasa and its tablet. A pilot study was carried out to fix quantity of cow's butter as levigation media. Based on results of the pilot study, LMV Rasa was prepared in two groups, that is, LMV 50 (LMV Rasa - prepared with weight of freshly prepared butter in 50% quantity of total ingredients) and LMV 75 (LMV Rasa prepared with weight of freshly prepared butter in 75% quantity of total ingredients). Complete drying of levigated mass and minimal spreading of fatty portion on filter paper was considered as the end point of levigation. Tablets of both samples were prepared by adding Pippali and honey in it and analyzed for their quality control parameters. Results: Twenty-eight hours duration of repeated levigation was required in LMV 50 which was prolonged up to 48 h in batch carried out in rainy season. In LMV 75, comparatively maximum duration of 54 h was required for levigation which was prolonged in the rainy season to 88 h. In both groups, lemon juice required for repeated levigation was 10 times of quantity of butter added initially. Conclusion: From pharmaceutical point of view, preparation of LMV Rasa tablets with quantity of butter in 50% of total ingredients is more convenient.
