Introduction:
Herbal medicine and other forms of complementary and alternative medicine (CAM) are used to treat symptoms of psychiatric disorders in the United States, including anxiety and mood problems. In Traditional Tibetan Medicine anxiety and depression are commonly treated with an herbal compound known as Agar-35.
Objective:
The objective of this pilot study was to explore whether Agar-35 tea would improve anxiety, affect, stress, and rumination.
Methods:
Undergraduate psychology students (N=14) were randomized to drink either Agar-35 tea (n=6) or placebo tea (n=8) for 7 nights.
Results:
The results indicated that Agar-35 significantly reduced participants' negative affect compared to placebo, U = 6.0, p = .019, effect size, r = .63. Further, Agar-35 also reduced anxiety (trending toward significance), U = 10.0, p = .071, effect size, r = .48.
Conclusion:
In accordance with its use in Tibetan Medicine, these preliminary findings suggest that Agar-35 may benefit aspects of psychological health.
