Purpose: This study was done to compare the effects of abdominal aroma massage and meridian massage on constipation and stress in college women with functional constipation. Methods: The participants were 38 college women, 18 were in the aroma group and 20 in the meridian group. The aroma massage was given using aroma oil which was a mixture of lemon, lavender, rosemary, and cyprus. The meridian massage was given at 9 accupoints which influence intestinal functions. The treatment was given 5 days a week for 4 weeks. A constipation severity score, weekly defecation frequency, and a stress response score were measured before and every week of 4 weeks of the experiment. Results: While there was no significant difference between two groups, there was a significant difference within the groups in the constipation severity (aroma group: 1st week, meridian group: except 4th week), defecation frequency (aroma group: 3rd week, meridian group: 2nd and 3rd week), and stress (aroma group: all weeks, meridian group: except 4th week) after different duration of experiment. Conclusion: Based on these results, both abdominal massages relieved constipation and stress. Resorting to either types of massage will contribute to the reduction of use of stool softeners, suppositories, or enemas.
