Rating (out of 5): 2

Black tea has been used traditionally in many cultures as a general pick-me-up and to promote alertness and sociability, which can indirectly impact mood. The presence of caffeine in black tea is known to have mild psychoactive effects, increasing alertness and potentially improving mood temporarily. Additionally, black tea contains the amino acid L-theanine, which has been studied for its calming effects and ability to modulate the stimulating impact of caffeine. However, there are no strong historical records specifically indicating the use of black tea for treating mood swings in the way herbal remedies like St. John’s wort are traditionally used for mood disorders.

From a scientific perspective, there are some small studies suggesting that the combination of caffeine and L-theanine may enhance cognitive performance and have modest mood-stabilizing effects, such as reducing anxiety or promoting relaxation without drowsiness. However, clinical evidence supporting the use of black tea specifically for mood swings or mood disorders is limited and not robust. Most of the scientific literature focuses on green tea or isolated L-theanine rather than black tea itself. Therefore, while black tea has a traditional role in mood support due to its stimulant properties, the scientific evidence for its use in treating or supporting mood swings is weak and indirect.
