Health Notes

High content of catechins and polyphenols neutralizes free radicals, slowing oxidative stress in cells. Regular consumption is associated with reduced risk of chronic diseases.

Moderate caffeine combined with L-theanine provides gentle concentration without nervousness: caffeine activates the nervous system, L-theanine stimulates alpha waves and softens stress response.

Polyphenols reduce total cholesterol and LDL levels, decrease blood viscosity and thrombosis risk; flavonoids strengthen capillary walls.

Catechins have mild antibacterial effect on the gastrointestinal tract; moderate amount of tannins normalizes peristalsis. Traditionally oolong is recommended with fatty food as a natural "fat burner."

Polyphenols and caffeine jointly stimulate lipolysis and accelerate basal metabolism; several studies indicate moderate effect in body weight control.

Catechins enhance lymphocyte response to viral and bacterial aggressors; fluorine from Wuyi rocky soils strengthens tooth enamel and prevents caries.

β-carotene in tea serves as precursor to vitamin A, which is necessary for corneal and lacrimal gland health.

L-theanine increases synthesis of GABA, serotonin and dopamine, reducing anxiety levels without sedative effect.

Price and Authenticity

200–800 yuan per 500g (~$25–100); accessible category.

300–1200 yuan per 500g (~$40–160).

800–5000+ yuan per 500g (~$110–700+); price determined by specific plot, roasting degree and producer reputation.

authentic Ai Jiao has tight thin thread with characteristically twisted tips; loose or large roll — sign of different cultivar.

genuine rock tea should not smell of artificial flavorings, added flowers or raw moisture.

authentic "Yan Yun" — mineral, deep, long aftertaste — is practically impossible to imitate using raw material from other regions. If aftertaste is watery and quickly disappears — likely Waishan or non-genuine Wuyi.

Zhengyan cheaper than 600–800 yuan per 500g — sign of possible falsification.
