Ginger tea and caffeine: check what is blended with the ginger

The word tea covers different drinks

Ginger can be steeped as a herbal infusion. That is different from adding ginger to leaves of the tea plant. Harvard’s caffeine guide distinguishes herbal infusions from caffeinated black and green teas; a prominent ginger name on the package does not identify everything in the blend. [1][2]

Read the full blend rather than the front label

Look for black tea, green tea or a stated caffeine content. Decaffeinated tea is also different from a naturally caffeine-free ginger infusion: small residual amounts can remain. Brewing strength and the amount consumed affect exposure, so a single caffeine number cannot describe all ginger drinks. [1]

Make the comparison with the actual serving

Imagine one mug contains sliced ginger and hot water while another is a ginger black-tea blend. Both taste of ginger, but only the second has tea leaves as a caffeine source. If avoiding caffeine is the goal, choose a clearly identified caffeine-free blend and check any added ingredients. [1]

Hypothetical example — apply the food-specific distinction
Situation	Practical interpretation
Ginger and water	No caffeinated tea leaves
Ginger black tea	Contains a caffeine source
Decaffeinated blend	Not necessarily zero caffeine
