Pukyong National University Confirms Lime Peel's Sleep Improvement Effects Comparable to ‘Sleeping Pills’
- Research by PhD student Kim Seong-hee Published in Top Alternative Medicine Journal
Pukyong National University (President Baek Sang-hoon) announced that PhD student Kim Seong-hee from the Department of Food Engineering has published research confirming that lime peel extract has excellent sleep improvement effects in humans.
Kim Seong-hee's paper, titled ‘Efficacy and safety of standardized lime peel supplement in adults with sleep disturbance: A randomized, double-blind, placebo-controlled, polysomnographic study’(supervised by Professor Cho Seung-mok), was recently published in the international journal [Phytomedicine] (IF: 6.7), which is ranked within the top 5% of alternative medicine journals.
Kim Seong-hee, a doctoral student, conducted a clinical study using polysomnography for this research. The results showed that lime peel extract significantly improved sleep indicators, including increased sleep efficiency, total sleep time, decreased sleep latency, reduced wake time after sleep onset, and increased Stage 2 sleep.
Notably, the lime peel extract improved sleep efficiency by about 8.5%, a level comparable to well-known sleep medications, demonstrating its remarkable effectiveness. This research has been featured in the Biological Research Information Center (BRIC)'s 'People Who Shine in Korea' and highlighted as a major article in 'NutraIngredients,' a global functional food media outlet, drawing significant attention.
Kim Seong-hee, a doctoral student, along with Professor Cho Seung-mok, published a groundbreaking preclinical study on the sleep effects and mechanisms of lime peel extract in the top 5% international journal in the field of pharmacology, *Biomedicine & Pharmacotherapy* (IF: 6.9) last year. In this follow-up clinical study, Kim confirmed the effectiveness of lime peel extract.
In addition, Kim Seong-hee has been working at Nutra-it, a venture company founded by her advisor, conducting research on the commercialization of lime peel extract. Recently, she has signed Non-Disclosure Agreements (NDAs) with global functional food companies and is in negotiations for the export of lime peel extract. This year, she is also expecting to receive individual recognition for the functional ingredient in domestic health supplements and approval from the U.S. FDA for New Dietary Ingredients (NDI).
Professor Cho Seung-mok stated, "Faculty entrepreneurship or research commercialization in research labs with excellent research achievements is a good choice for continuous research and talent development. In particular, industrialization research in the Department of Food Engineering, which has high applicability and practicality, is suitable for developing the practical skills of graduate students, and we will continue to expand industrialization research in the future."
