Huangdai Tablets are a kind of compound prescription made of plant and mineral extracts.

The research was led by Chen Zhu, now minister of health and a member of the Chinese Academy of Sciences, and Chen Saijuan, executive director of the Shanghai Institute of Hematology and a member of the Chinese Academy of Engineering.

"The research is quite interesting and established a good example using the traditional Chinese compatibility medicine to treat patients," said Yung-Chi Cheng, a professor of Yale University School of Medicine, who is the leading expert on biochemical and molecular pharmacology.

Leukemia is a cancer of the blood or bone marrow characterized by an abnormal proliferation (production by multiplication) of blood cells, usually white (leukocytes).

Huangdai Tablets, a kind of traditional compatibility medicine, have long been administered in the treatment of the disease.

Chen Zhu and his colleagues made a thorough investigation into Huangdai Tablets containing active components from realgar, indigo and red sage root in a combination termed RIF.

They analyzed the role of each ingredient and found the effects of RIF were synergistic, with none of the ingredients working as effectively when individually administered.
