In the Current Study 60 Patients of Tamak Shwas have been selected randomly divided in two groups. The patients showing classical symptoms of Tamak Shwas such as Shwaskruchhrata (Dyspnoea), Kasten Bhashya (Difficult in Expectoration) Ghur-Ghurak Shabda (Wheezing or Rhonchi) During night, Kasten Shleshma Moksha (Difficult in Expectoration), Kasa (Cough), , Anidra (Insomnia) etc. were included in this study. For the present study we were given Krishnadi Choorna orally. It reduces Respiratory Rate effectively & increases Expansion of Chest, Breath Holding Time, and Peak Expiratory Flow Rate & Sustained Maximal Inspiration which was highly significant statistically as compared with Tab. Deriphyllin. At the end of the study it was found that Krishnadi Choorna in Group A is more effective than in Group B.
