With growing health consciousness in today’s world, natural supplements are gaining attention.
This time, we’ll introduce the story and appeal behind the development of our supplement made from Gynura bicolor.

A supplement developed in collaboration with academia
This supplement was developed in collaboration with Professor Tomihisa Ohta, Professor Emeritus of Kanazawa University and Doctor of Pharmacy, a leading expert in Gynura bicolor research. Professor Ohta filed a patent for "a hypoglycemic agent using Suizenjina" on October 21, 2004, and holds more than 40 other patents.
The main patents are as follows:
- Pharmaceutical enzyme inhibitors derived from Ichigo and their manufacturing methods
- Food and pharmaceutical compositions using Hatomi leaves
- Preventive or therapeutic agents for tumors or viral diseases such as breast cancer
Based on these rich research results, the development of scientifically grounded supplements has become possible.
