Hekizanen has formed a research group with many universities, and was adopted as a "research network for the creation of new epoch-making functional foods" at the base of the "research network formation project" of the Ministry of Agriculture, Forestry and Fisheries.
Discovered a new compound suppressing the growth of cancer stem cells from Tochu
Named "Eucommicin A"
Utilizing artificial cancer stem cells produced by IPS cell technology.
Expectations for new drug development
We found a new compound that specifically suppresses the proliferation of these cells in the components of Tochu leaf by using artificial cancer stem cells that also have the characteristics of stem cells, This research was carried out using Hekizanen's Tochu Cha tea (Eucommia Tea). Hekizanen also holds a substance patent jointly with the university.

A study by the University of Toyama analyzed the genesis of Tochu leaf, and it became clear that Tochu Cha tea from Hekizanen is rich in iridoids such as geniposidic acid, polyphenols, and asperuloside.
