Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Camellia sinensis, the plant from which green, black, and other teas are made, has a long history of traditional use for relieving mild headaches, including tension-type headaches. In traditional Chinese medicine and other Asian medical systems, tea has been consumed for its perceived ability to clear the mind and alleviate discomfort, sometimes including headaches. The proposed mechanisms are related to its caffeine content, which is known to have vasoconstrictive properties and is an ingredient in some modern over-the-counter headache remedies. However, the direct scientific evidence supporting the use of Camellia sinensis tea specifically for tension headaches is limited. Some clinical studies on caffeine suggest that it may provide mild relief for certain headache types, but the research is generally focused on isolated caffeine or caffeine-containing medications rather than on tea itself. Additionally, the amount of caffeine in tea can vary widely and is generally lower than in coffee or pharmaceutical preparations. There is little to no robust clinical research directly validating the efficacy of Camellia sinensis for tension-type headaches, so its use is primarily supported by tradition and anecdotal experience rather than strong scientific evidence.
