Emory University scientists recently published a study in Nature that suggests that parietin — a compound found in rhubarb — may help prevent cancer cells from growing. In fact, parietin was so effective that it killed off half of a sample culture of leukemia in about two days. Experiments on mice with lung cancer were also promising. Just as important, parietin is significantly less dangerous than chemotherapy drugs to healthy tissue. Rhubarbs have other benefits as well, including lots of vitamins A and K, as well as potential anti-Alzheimer’s properties.
- Parietin, which is found in various lichen, offers protection against the sun’s ultraviolet light.
- An in vitro study revealed that parietin destroyed about half of the leukemia cells in a dish over a 48 hour period.
- A separate in vivo study, conducted using rodent subjects, showed results that correlated with the in vitro study.
