ONLY Purple Tea from the Rift Valley of Kenya has a fifth marker called "GHG" ..."The Fifth Element "
The Tea Research Foundation of Kenya has released a purple tea variety, Purple Tea for commercial utilization targeting a unique tea product - . This cultivar has been under development for the last 25 years and further works on the composition and antioxidant value of anthocyanins in it are still in progress.
The cultivar has been pre-released in response to the government’s vision 2030 and Medium-Term Plan 2008-2012 (MTP), targeting new tea products diversification and value addition in order to enhance productivity of teas as well as to boost economic growth in the agricultural sector. Anthocyanins are diverse flavonoids and are soluble in water. They are also powerful antioxidants and have health enhancing properties.
Anthocyanin supplements (proanthocyanins) are widely marketed for their health enhancing properties. Anthocyanins are also widely used as preservatives especially in the food industry. The new tea variety that is rich in anthocyanins will provide an alternative raw material from which these flavonoids can be extracted.
The other products that can be produced from the purple tea leaf and which the Foundation’s scientists are researching on, include extracted catechins, anthocyanins, anthocyanidinins (which are used as drug supplements, preservatives and other industrial uses), tea polyphenol extracts for pharmacological and industrial uses, manufacture of instant teas, Ready To Drink (RTD) tea, and other fast moving consumer goods such as health care products, foods and confectioneries.

According to a human trial study by an Asian firm, Purple tea/extract (PTE) is the only tea containing GHG.
