Herbal teas phytochemicals science research

The science of good tea

Longeviteas were developed by Dr. Jessica Cail, a research psychopharmacologist specializing in mind-body medicine. The herbs and flowers in these blends were selected because of the particular phytochemicals (chemicals naturally found in plants) that they contain… chemicals that peer-reviewed scientific research has found to be strongly associated with longevity, vitality, or tranquility.

How do they work?

Although the exact mechanism of action of these substances varies from herb to herb, in general every blend contains potent anti-inflammatory substances, plus some which are mildly diuretic. Given that inflammation is the basis of many unhealthy processes in the body, ranging from auto-immune disorders to Alzheimer’s disease, and that salt/water balance is related to blood pressure and overall cardiovascular health, it perhaps shouldn’t come as a surprise that areas of the world in which we see high consumption of these phytochemicals are the same areas that show the longest lifespans.


Although each blend was designed for a specific purpose,

ALL of them contain the herbs & spices associated with long life.


where did you get your info?

As a scientist, I don’t believe anything unless I’ve seen the actual studies for myself…and not just one, but a bunch of them, all pointing in the same direction. Below are the peer-reviewed scientific journal articles I used to create our formulations. Yes, I read every one, cover to cover. These articles were used to check each ingredient in every blend for its overall activity (not all herbs DO anything), its bioavailability when ingested orally (not all substances can be absorbed orally), its ability to be extracted into hot water (not all phytochemicals can be extracted that way, and some lose potency when heated), and most-importantly, to check their safety and efficacy at those doses. I encourage you to look through these references yourself. Most are available via search of the National Library of Medicine. If there’s an article you’d like to see that you can’t find, send me an email at jess@longeviteas.com and I’ll send you a copy. A good scientist always follows the data.
