Research Outline and Core Summary
Purple is superior, green is secondary.
Lu Yu, the "Sage of Tea" in China , once praised purple bud tea, saying, "Purple is superior, green is inferior." "AromaPrime Black Tea" has 87% purple-red color and a unique aroma, thanks to its high-quality tea tree variety that has undergone a mutation and reddening process.
The "2015 Chinese Agricultural Science Research on the Utilization of Red and Purple Tea Buds" shows that the anthocyanin and lipid-type catechin content of red leaf and red heart tea is 10-50 times higher than that of ordinary tea, and has significant antioxidant and anti-aging effects.
Anti-aging research and human trials of modern red and purple bud tea
Human trials: After drinking purple bud tea daily for 3 weeks, subjects showed a 15% increase in plasma antioxidant capacity (ORAC value).
Research: Liu Z, et al. Purple tea improves antioxidant status in healthy adults. J Nutr Biochem. 2018;58:30-37.
The unique characteristics of purple bud tea: Purple bud tea has a significantly higher anthocyanin content than ordinary tea.
Research: Zhao Y, et al. Anthocyanin composition and antioxidant activity of purple tea. Food Chem. 2020;331:127356.
Telomere protection and cell senescence
Anthocyanins slow down telomere shortening (telomere length is related to cell replication lifespan).
Research: Shay JW, et al. Anthocyanins extend lifespan in Drosophila melanogaster. Aging Cell.
Skin anti-aging
Purple sweet potato and skin elasticity: Purple sweet potato extract can reduce UV-induced collagen degradation.
Research: Tominaga Y, et al. Purple sweet potato anthocyanins attenuate skin photoaging. J Dermatol Sci. 2019;93(1):41-48.
Wrinkle improvement: Clinical trials have shown that consuming purple cabbage extract for 12 consecutive weeks can reduce the depth of facial wrinkles.
Research: Jeon YJ, et al. Effects of purple cabbage extract on skin aging. J Cosmet Dermatol. 2020;19(2):474-481.
Antioxidant mechanism : Anthocyanins reduce oxidative stress by scavenging free radicals (ROS) and activating endogenous antioxidant systems (such as the Nrf2 pathway).
Research : Wallace TC, et al. Anthocyanins in Cardiovascular Disease . Adv Nutr. 2011;2(1):1-7.
Long-term consumption of purple vegetables can lower blood pressure, blood sugar, and blood lipids (indirectly delaying organ aging).
Research: Wu X, et al. Purple vegetable consumption and metabolic health. Nutrients. 2017;9(2):128.
Shi Jikang began research on AromaPrimeTea in 1950, and Shi Liqiang began variety finalization in 2000. Anthocyanins belong to the flavonoid polyphenolic compounds, which can inhibit lipid peroxidation, scavenge free radicals, and have antioxidant, anti-aging, weight loss, and anti-radiation effects.
AromaPrime black tea, made from red and purple buds, is a crystallization of nature's gifts and craftsmanship.
We thank Shi Jikang and Shi Liqiang, two generations of the Shi family, for contributing unique black tea varieties and exquisite techniques to the world.
