1.  Pharmacognostical and phytochemical evaluation of Vara Asanadi Kwatha 
Ayu  2012;33(1):130-135.
Vara Asanadi Kwatha (VAK) is a compound Ayurvedic formulation prescribed in the management of obesity. Pharmacognostical study counting both macroscopic and powder microscopy of raw drug exposed the quality and genuineness of all the constituents of VAK. Organoleptic features of coarse powder made out of the crude drugs were within the standard range. Specific gravity of the decoction was 1.0185 and pH was 5.5.Total solid content present in the Kwatha was 4.525% w/v, total ash 0.949% w/v, and acid insoluble ash was 0.052% w/v. Iron assay showed the presence of Fe2O3 as 0.065% w/v. Qualitative scrutiny demonstrated the presence of flavonoids and tannis. Thin Layer Chromatography (TLC) and High Performance Thin Layer Chromatography (HPTLC) were carried out after organizing appropriate solvent system in which maximum three spots were distinguished in TLC and nine spots in HPTLC and most of the Rf values were identical when done with different sample extractive methods. This shows the presence of certain definite constituents in the decoction and is helpful for the easy separation of these constituents.

2.  A comparative study of Kaishora Guggulu and Amrita Guggulu in the management of Utthana Vatarakta 
Ayu  2010;31(4):410-416.
Vatarakta is the major example of Vata vyadhi, caused due to avarana pathology. The scenario of Utthana Vatarakta occurred owing to the margavarana pathology, which can very well be correlated with atherosclerotic peripheral arterial disease. The literature enlists a number of Guggulu prayogas in the management of Vatarakta. An additional cavernous revise was indispensable to bring out the precise outcome of these products. Keeping these visions in mind, the particular comparative study was performed with Kaishora guggulu and Amrita guggulu, which are explained in the same context. This is a single-blind comparative clinical study with a pre-test and post-test design, wherein a minimum of 30 patients of either sex, suffering from Utthana Vatarakta, in an age limit of 16 to 70 years, were selected and randomly categorized into two groups. The 15 patients of group A were treated with oral administration of Tab Kaishora guggulu 1 g thrice a day and the group B patients with Tab Amrita guggulu of the same dose pattern with anupana of lukewarm water. The therapeutic effect of the treatment was assessed in both the groups based on specific subjective and objective parameters. The results obtained were analyzed statistically in both the groups and the comparative effect was assessed using the unpaired “t” -test. In the present study, 80% of the patients from both the groups had madhumeha (Diabetes mellitus), shonita mada (Hypertension) or both. Fifty percent of the patients in group A and nearly 60% of the patients in group B, suffering from Utthana Vatarakta, had the habit of smoking.In both the groups, a statistically significant improvement was observed in all the criteria of assessment. The outcome of the study revealed an identical therapeutic efficacy of Kaishora guggulu and Amrita guggulu in Utthana Vatarakta. The use of Kaishora guggulu or Amrita guggulu as shamana Aushadhas was a perfect selection in the management of rakta margavaranajanya Utthana Vatarakta.
