Clinical Trial for the Evaluation of the Efficacy and Safety of EDL on Dyspepsia

A 12 Week, Randomized, Double-blind, Placebo-Controlled Clinical Trial for the Evaluation of the Efficacy and Safety of EDL on Dyspepsia

This clinical trial was designed to evaluate the functional and safety effects on dyspeptic symptoms compared to the placebo when ingested with EDL (Extract of Dolichos lablab Linne) in adults who complain of dyspeptic symptoms.

Dyspepsia is a common disease and accounts for about 5% of all patients visiting primary care. Of these, about 70~90% of dyspeptic patients who visit the tertiary medical institution have functional digestion, considering that about 8~20% of dyspeptic patients who are referred from the primary medical institution to the tertiary medical institution are found. It is estimated to be bad. Functional dyspepsia is not life-threatening, but its symptoms persist throughout life and are not easily cured, which can limit social life and reduce the quality of life.

Therefore, this clinical trial was designed to evaluate the functional and safety effects on dyspeptic symptoms compared to the placebo when ingested with EDL (Extract of Dolichos lablab Linne) in adults who complain of dyspeptic symptoms.
