Chamomile and L-theanine beverage reduces menstrual pain and improves mood and sleep quality in young women with primary dysmenorrhea
A randomized, double-blind, placebo-controlled study found that daily consumption of a chamomile and L-theanine beverage (CTT) for five days around menstruation significantly reduced pain intensity by 57.17% (VAS) and 55.46% (NRS) compared to baseline. The intervention also significantly decreased severity of lower abdominal pain, back pain, depression, irritability, and daytime dysfunction by 31-56% in young women with primary dysmenorrhea.

The Claim
Chamomile and L-theanine beverage reduces menstrual pain and improves mood and sleep quality in young women with primary dysmenorrhea
This conclusion is most relevant to: Young adult females with primary dysmenorrhea (n=30 total, 15 per group).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Effects of chamomile and -theanine beverage on menstrual pain, menstrual symptoms, mood, and sleep quality in young women experiencing primary dysmenorrhea: A randomized, double-blind, placebo-controlled study. (Journal of food and drug analysis, 2026) —
How It Works
The proposed biological pathway:
- ▸Chamomile and L-theanine are consumed as a beverage
- ▸Active compounds exert anti-inflammatory and anxiolytic effects
- ▸Reduction in prostaglandin-mediated pain and stress response
- ▸Result: Decreased menstrual pain, improved mood and sleep quality
Who Might Benefit
Evidence fit by population:
- ▸Young adult females with primary dysmenorrhea (n=30 total, 15 per group)
Recommended Dose
Not specified (beverage consumed daily for five days)
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Small sample size (n=30 total, 15 per group)
- ▸Short intervention duration (only five days per menstrual cycle)
