Bhaishajya Kalpana is accountable for the preparation of several medications, such as Vati, Churna, Asava, Arishta, Taila, and Avaleha. It includes pharmaceutical manufacturing as well as quality control procedures from raw material procurement to the final product. In Sneha Dravya, crude medications in their basic dosage form, including Kalka and Kwatha, are made by cooking (paka) them with water, milk, and additional substances as needed to create Sneha Kalpana, a secondary dose form. This is carried out in compliance with the Sharangdhar Samhita's recommended ratio of 1:4:16 for Kalka, Sneha, and Drava Dravya. It can be used internally as Pana, Anuvasana Basti, and Nasya, and externally for Abhyanga. Haridradya Taila, which is used to treat Arunshika, is composed of extracts from local herbs such as Haridra, Daruharidra, Bhunimba, Amalaki, Haritaki, Bibhitaki, Nimba, Rakta Chandan, and Tila Taila. The analytical components of Haridradya Taila along with its preparation, have been done in this research.
