Scientists, led by Chun-Tang Chui from the Institute of Biochemistry and Biotechnology in Taiwan....
A recent study published in THE SUN found that Hibiscus sabdariffa leaf extract inhibits human prostate cancer cell invasion.
Another
study by the same team of researchers, found that the polyphenols
present in hibiscus leaves may inhibit growth of and destroy melanoma
cancer cells without damaging healthy human skin cells, scientists from
Taiwan have found.
Hibiscus
leaf is a rich source of polyphenols, which are thought to have
hypolipidemic (lipid-lowering) and antioxidant effects. The scientists
claimed that this was the first study focusing on the polyphenols and
their anti-melanoma mechanisms.
Commonly
called roselle or zobo, Hibiscus sabdariffa belongs to the plant family
Malvaceae. In folk herbal medicine, it is used to treat hypertension,
pyrexia, and liver disorders, and is used for its immune-modulating
effect in Asia.
An
aqueous extract of dried flowers of H. sabdariffa L. has been used as an
effective treatment against leukemia and gastric carcinoma, due to its
high content in polyphenols.
