Talk:Tea

Active discussions

Tea is an aromatic beverage commonly prepared by pouring hot or boiling water over cured leaves of the Camellia sinensis, an evergreen shrub native to Asia. The word "tea" generally implies the use of tea leaves (Camellia sinensis), but tea can be made out of many plants.

Chemistry

Tea contains both theanine and caffeine as well as many other compounds known. [citation needed] The younger the leaf, the more caffeine it tends to have.[1]

Religious use

Tea has been used by Buddhist monks since the Sui Dynasty (589–618 BC) to maintain a state of “mindful alertness” during long periods of meditation.[2]

Tea cermony

A tea ceremony is a ritualized form of making tea practiced in Asian culture by the Chinese, Korean, Japanese, Indian, and Vietnamese.[citation needed]

Subjective effects

Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), an open research literature based on anecdotal user reports and the personal analyses of PsychonautWiki contributors. As a result, they should be viewed with a healthy degree of skepticism.

It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠.

Physical effects
 

    • Stimulation
    • Frequent urination - When doses of caffeine equivalent to 2–3 cups of coffee are administered to people who have not consumed caffeine during prior days, they produce a mild increase in urinary output.[3] Most people who consume caffeine, however, ingest it daily. Regular users of caffeine have been shown to develop a strong tolerance to the diuretic effect.[4]
    • Vasoconstriction and Vasodilation - Whilst caffeine acts as a mild vasoconstrictor, its metabolite theobromine is a vasodilator and these effects are thought to cancel each other out.
    • Increased blood pressure
    • Increased heart rate
    • Nausea - Moderate to extreme nausea has been reported to occur, typically at higher dosages.
    • Stamina enhancement

Cognitive effects
 

  • The cognitive effects of caffeine can be broken down into several components which progressively intensify proportional to dosage. It contains a large number of typical stimulant cognitive effects. Although negative side effects are usually mild at low to moderate dosages, they become increasingly likely to manifest themselves with higher amounts or extended usage. This particularly holds true during the offset of the experience. The most prominent of these cognitive effects generally include:
