What the Research Shows
As with many herbal remedies, most of ashitaba's success is anecdotal based on centuries of positive results. However, despite the lack of clinical human trials on the herb, some animal research has taken place.
- Ashitaba is abundant in chlorophyll, which may reduce the risk of cancer. Research published in Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids showed the antioxidant properties in chlorophyll make it beneficial for fighting free radicals (damaging molecules that promote aging, destroy tissues, and promote disease in the body). According to Oregon State University, a study on rainbow trout determined chlorophyll, and its derivative, chlorophyllin, protects against cancer against "the modest carcinogen exposure levels most likely to be found in the environment." However, the study also determined that at high levels of exposure, chlorophyll increases the number of tumors.
- A study published in the Journal of Nutrition Science and Vitaminology on rats fed a high-fat diet and ashitaba for 28 days showed positive results. The study concluded ashitaba may be a source of dietary fiber and might improve gastrointestinal health through the increased excretion of bile acids through feces.
- According to research on mice published in the Journal of Agricultural and Food Chemistry, Ashitaba contains two chalcones, or flavanoid compounds, with insulin-like abilities. One in particular, 4-hydroxyderricin, displayed "preventive effects on the progression of diabetes in genetically diabetic KK-Ay mice."
