Following statistical techniques were used to analysis the study.
Descriptive statistics/univariate analysis: Descriptive statistics/ univariate analysis (such as mean, frequencies and percentages) of data were performed to identify the main characteristics of the research variables.
Paired-samples t test
The paired-samples: T Test procedure compares the means of two variables. The procedure computes the differences between values of the two variables for each case and tests whether the average differs from 0.
Confidence interval: By default, a 95% confidence interval for the difference in means is displayed. Enter a value between 1 and 99 to request a different confidence level.
Missing values: When test several variables and data are missing for one or more variables, can tell the procedure which cases to include (or exclude):
Exclude cases analysis by analysis. Each t test uses all cases that have valid data for the tested pair of variables. Sample sizes may vary from test to test.
Exclude cases list wise. Each t test uses only cases that have valid data for all pairs of tested variables. The sample size is constant across tests.
Effect of therapy on hard stool
100% of selected patients were show hard stool. Initial mean value of hard stool was 2.27 and 15th day it reduced into 0, it means hard stool never occur following to 15th day of treatment and also statistically highly significant result with ‘p’ value 0.000 in hard stool was observed (Table 1).

Overall effect of improvement
Figure 1 shows comparative overall effect on the management of constipation. The results were highly significant in symptoms. Hard stool, Excessive staining, incomplete evacuation, Lower abdomen fullness and Gas collection were considered for comparing the overall results. Initial Comparative Mean value was 2.40 , comparative mean after treatment 1.65, 1.07, 0.39 and 0.05 on 3rd day, 6th day, 10th day and 15th, day respectively and 20th day it completely reduced into 0.00, it means Constipation never occur following 20th day of treatment.
Effectiveness is explained on the basis of taste, potency and result and action and properties of selected plant. According to Siddha, dietary and lifestyle reasons may initially lead to derangement of Vatha or Pitha causing indigestion, bloated abdomen, gassiness etc. to treat constipation, drugs acting on both Vátha and Pitha should be selected.3
The plant Picrorhiza scrophulariiflora Pennell has bitter and pungent taste, hot potency and pungent resultant. Bitter taste has Combination of air and space elements and pungent taste has Combination of air and fire elements.so prominent five elements in this plant is air element. Air element has denselessness, dryness, easiness, and inhalation properties. And also bitter taste reduces the body heat and improve bowel functions, pungent taste get rid of the distended abdomen due to indigestion. Therefore it is mildly laxative by nature.4
The plant is hot potency, it increased the Pitha which increases the Dhatuvagni (cell metabolism) as result indigestion will be set off. So it helps to digest the food particles and the plant is pungent resultant which helps in pacification of aggravated Vátha.4
Above explanations has been supported by the results obtained from this study.
Picrorhiza scrophulariiflora Pennell can be used as an effective internal administration for constipation and no strict side effect was detected. Statistically highly significant (p value 0.000) improvements in parameters like hard stool, excessive straining, incomplete evacuation, lower abdominal fullness and gas collection, the improvement remained same after the follow up period.
All 30 patients got relief from the symptoms on 20th day onwards, therefore the plant Picrorhiza scrophulariiflora Pennell can be recommended for constipation 650mg capsule two times a day for 20 days.Gunapadam porudpanpunool Moolikai Thokupu part 1 written by Murukesa muthaliyar mentioned Picrorhiza scrophulariiflora Pennell has an action to relived constipation. This was scientifically proved by this study.
Evaluate the effectiveness of Picrorhiza scrophulariiflora Pennell on the management of constipation since it is a under graduate research procedure, therefore the future research can be consider with large number of patients.
