The study was conducted by examining lung function, then continued with 250 grams of red ginger steeping therapy for 4 months.

The normality test showed that the average per month all data were normally distributed (Pvalue>0.05). Then continued with the t-test showing that there is a significant change every month (P value=0.000). Infusion of red ginger for 4 months was proven to be effective in increasing lung function from the parameter values of FEV1/FVC significantly.
