Introduction: Higher-order Siddha medicines such as Parpam and Chenduram are mainly prepared by the Pudam (calcination) process. The Pudam process is measured by the number of cow dung cakes (Varatti) used for the calcination process. The commercially available cow dung cakes are in various sizes, shapes, and thicknesses. Hence to overcome these difficulties, an attempt has been made to standardize the cow dung cake used for the Pudam process. Materials and Methods: An aluminum ring-like mold was made with the dimensions of 30 cm diameter and 1.25 cm height as a mold for preparation of cow dung cakes. In this study, Kaadai Pudam, Kowthari Pudam, Kukkida Pudam, Varaga Pudam, Manal maraivu Pudam, and Gaja Pudam were done, and standardization of heat generation during the Pudam process is recorded by the digital thermo-sensor and validated for different types of Pudam processes by using standard size cow dung cakes. In addition, the time duration of the Pudam process, peak temperature, and the sustain of peak temperature was also noted. Results: The time duration of the entire Pudam process of the aforementioned pudam processes was noted as about 4 h 50 min, 6 h 20 min, 8 h 40 min, 9 h 55 min, 10 h 35 min, and 17 h 50 min, respectively. Conclusion: The obtained results of temperature and time duration for each variety of Pudam process may help to establish the modernized technology-based instruments to prepare higher-order Siddha calcination medicines, without compromising the standard and quality of medicines.
