Purva Karma

Firstly, Kajjali was prepared by Samguna Parada & Gandhaka. Fine Churn of raw drug was prepared. Vatsanabh Kwath was prepared. For further Putpaak process Upalas and pyrometer were arranged.

Pradhana Karma

Kajjali was triturated for atleast 1 to 2 hour. Then Samguna Kajjali (100 gm) and Raw drugs Churna of Pippali, Gorakhmundi, Vasa, Vibhitaki & Haritaki each 50 gm were taken are triturated for sometime. Next 250 ml Vatsnabh Kwath was added in the mixture of Samguna Kajjali & Raw Drugs, then trituration process starts for few hours until the mixture become even. After that Bolus were made & kept sometimes and wrapped with Erand Patra & tied with thread and 3 layers of ½ Angul Mrittika & 3 layer of Kapadmitti was done one by one & kept for drying. Then complete bolus was subjected to Putpaak process & Laghu Puta was given. In traditional Laghuput procedure, firstly 2/3 of the Puta was filled by cow dung then bolus was kept and 1/3 part was filled by cow dung cakes. Then thermocouple was arranged underneath Bolus and temperature were recorded carefully.

Paschat Karma

After Swangsheeta, bolus was taken out and examined for Siddhi Lakshan. Then bolus was triturated with Vasa Swaras and Badar Asthi Praman Vati was made. After that drying of Vati was done and continued till there was no more weight difference. Then the Vati were counted and preserved in air tight container.

Parada Shodhan

In standardization method in order to get rid of impurities present in the Parada. As limestone, garlic & salt are easily available, so this method was chosen for the purification of Parada. Purification of Parada is very important before using it in any formulation indicated for internal administration such as Shwasakasari Rasa. Total quantity of Parada taken was 500 gm for Shodhan with Sudha Churna & after its Shodhan 470 gm of Parada was achieved. Out of this 470 gm of Parada 400 gm was taken for further Shodhan with garlic & salt, and after Shodhan, Shodhit Parada got was 380 gm. Loss of Parada in gm is 20 gm & in % is 5%. The loss of Parada due to its five Gati as mentioned in classical text. Shodhit Parada observed was bright, shiny, white in colour because whole impurities get dissolved in Sudha Churn, garlic & salts. Total trituration hour taken was 96 hr. During this Shodhan process many observations were noted in regular interval of period.

Gandhak Shodhan

After the purification of Gandhaka it can be used safely for formulation of Shwasakasari Rasa. Sulphur Shodhan was done in Godugdha & Goghrita. As many Shodhan method has been given in classical text. The repeated heating, melting

and sudden cooling of sulphur by pouring it into liquid media may cause loosening of the bonds between the molecules making it amorphous in nature. This loosening of the bonds may be helpful in dissolving the impurities in the media thus separating it from the sulphur, making it pure. 500 gm of sulphur was taken for Shodhan after process Shuddha Gandhaka got 460 gm. Loss of wt. in gm is 40gm & in % is 8% was observed. This loss could be because of removal of physical & chemical impurities in the form of sand particles & loss during washing. Colour change was observed after Shodhan of Gandhaka.

Vatsanabha Shodhan

There are 3 important methods for Vatsanabha Sodhana. But, for the preparation of the medicine for Swasa & Kasa the drug of choice of Vatsanabha Shodhana was Gomutra compared to Gougdha, since Gomutra has Vatakaphahara property. This was the reason for choosing this method for Vatsanabha Sodhana. During Vatsanabha Sodhana, each time after Gomutranimajjana, analysis of Gomutra was done. pH of Gomutra was found to be decreased (became more acidic) after each Sodhana. Shuddha Vatsanabh was used in the preparation of Vatsanabh Kwath. It was used in trituration of drugs to make bolus.

Preparation of Shwasakasari Rasa

Pharmaceutical method adopted in the study was Shodhan, Mardana & Putpaka method. The total wt. of the finished product i.e., Shwaskasari Rasa was decreased due to Putpaka method. Parada wt. also decreases due to its Gati during trituration. Gandhaka wt. is also reduced after Shodhan because impurities get removed. After Shodhan wt. of Vatsanabh decreases due to pilling of its layer & then dried. Putpaak method of Shwasakasari Rasa was described in Rasayog Sagar, in this method Kajjali & fine powder of raw drugs (Pippali, Gorakhmundi, Vasa, Vibhitaki, Haritaki) was triturated with Vatsanabha Kwath & bolus is prepared. Bolus is wrapped in Eranda Patra & 3 layers of Mitti & 3 layers of Kapadmitti was wrapped one by one & Laghuput was given, temp given upto 570°C & kept for self cooling. When it is self cooled red droplets were seen on the Erand Patra. Bolus wt. is 110 gm & after Putpaka wt. reduced to 80 gm. After trituration with Vasa Kwath Badarasthi Praman Vati were made & get dried. Final wt. of Shwaskasari Rasa got 60 gm.


Samaskar is defined as “Gunantaradhana” it enhances the quality & efficacy of drug. Pharmaceutical procedure adopted in study of Shwasakasari Rasa was Shodhan & Putpaak. The ultimate objective of Shodhan process is to increase the bioavailability of the drug & further potentiating the biological efficacy. Many Shodhana method were mentioned for the purification of the ingredients of Shwasakasasri Rasa. To standardize a process, proper analysis should be done in each step. So, a detailed analytical study of each procedure during the preparation of Shwasakasari Rasa was conducted in present study and observation were noted carefully. In this study best method of Parada, Gandhak & Vatsanabh Shodhan was done so that it increases the quality & efficacy of drug. Putpaak method was done for the preparation of Shwasakasari Rasa so that it increases its efficacy.
