Green Tea Eye Fatigue Randomized TrialIt is important to gain an understanding of factors associated with poor quality of life as a patient’s perception of quality of life can predict treatment and intervention outcomes [].2Singh Prachi (2026)Effect of an herbal supplement on quality of life in participants with insomnia: A randomized placebo controlled cross-over pilot trial
Green Tea Eye Fatigue Randomized TrialWhile the relationship between insomnia, cardiometabolic risk, and quality of life is recognized, few physicians routinely conduct full sleep histories on their patients, and the patient satisfaction for insomnia treatment remains low [].2Singh Prachi (2026)Effect of an herbal supplement on quality of life in participants with insomnia: A randomized placebo controlled cross-over pilot trial
Green Tea Eye Fatigue Randomized TrialThe intervention duration was based on anecdotal evidence which suggested an acute same day effect on sleep.2Singh Prachi (2026)Effect of an herbal supplement on quality of life in participants with insomnia: A randomized placebo controlled cross-over pilot trial
Green Tea Eye Fatigue Randomized Trial1 2 3 Sleep and quality of life are closely entwined such that sleep disorders like insomnia are closely linked to poor quality of life [].2Singh Prachi (2026)Effect of an herbal supplement on quality of life in participants with insomnia: A randomized placebo controlled cross-over pilot trial
