Abstract
Objectives: The aim of this study was to analyze consumer experience with Digestive Enzymes, a digestive enzyme product that includes medicinal herbs (Multi-Zyme®). The goal was to provide basic data on improvements and marketability of future digestive enzyme products containing medicinal herbs. Methods: Qualitative research was conducted to explore the current participants' experience. In-depth interviews with a semi-structured interview guide were conducted to investigate the experience and perception of the participants. The participants were recruited using snowball sampling and purposive sampling, and a qualitative content analysis method was adopted. Credibility was ensured by adopting a member check, triangulation, and peer debriefing method. Results: In-depth interviews were completed with a total of 8 participants. The collected data were classified into 16 codes and then further divided into the following seven categories: direct buying, indirect buying, effects, questions, recommendations, positive perception, and negative perception. The categories were grouped into three themes: 'Experience of purchasing existing health foods', 'Experience of taking Multi-Zyme', and 'Opinions on selling Multi-Zyme at Korean medicine clinics'. Conclusion: The participants experienced effect of the Multi-Zyme® and were willing to recommend it around. However, the Korean medicine doctors need to inform consumers about the dose and duration when taking Multi-Zyme® to prevent abuse. Some consumers may trust Multi-Zyme® sales from Korean medicine clinics, but some held opinions that those sales were not trustworthy, so promotion and improvement are needed.
