People call Ri Hyon Il, teacher of the Chemistry Faculty of Kim Hyong Jik University of Education, "expert in Hibiscus manihot L.".
As many people say, Ri Hyon Il has better knowledge of the biological features and medicinal value of Hibiscus manihot L. than anybody else.
He says:
"I started my research work in 2016 to extract and separate the medicinal elements from this plant in a most effective way and uncover their pharmacological actions, that is, their bio-activities, one by one."
Hibiscus manihot L. is said to have a lot of natural physiological activators including flavonoid and rutin.
Such substances exist as chemical compound in general.
So, it was considered to be very difficult to extract and separate them.
Even if possible, it needed much effort.
Teacher Ri Hyon Il, however, did not follow the established theory.
He oriented his research to ensuring smooth extraction and separation with easy operation under simple production conditions.
As a result, he laid a solid foundation to extract and separate a larger quantity of natural physiological activators from all kinds of plants in whatever conditions.
His research findings have been introduced into the Huichon Koryo Medicine Pharmaceutical Factory in Jagang Province of Korea, proving effective.
"Hibiscus Manihot L. Nectar", "Hibiscus Manihot L. Flower Immunity-Active Pills", "Hibiscus Manihot L. Flower Granule" and other efficacious medicines and health foods of different kinds have been developed in succession, making an active contribution to the improvement of the people's health.
Teacher Ri Hyon Il has been well-known for his research into Hibiscus manihot L. Thanks to his devoted efforts, the range of use of the plant continues to be expanded in the Democratic People's Republic of Korea.
