What are the potential health benefits of Thallus laminariae?
Thallus laminariae has been used in traditionally Asian medicine for a long
time and people believe, it has various health benefits, especially for older
women. However, scientific evidence for its health claims is actually very
limited. Korea researchers from Kyung Hee University demonstrated its
scavenging-activity against DPPH (1,1-diphenyl-2-picrylhydrazyl) radicals.
 Researchers from the same school found a traditional Chinese herbal
formula " Shikunshito-Kamiho" containing Ginseng Radix, Hoelen,
Atractylodis Rhizoma, Glycyrrhizae Radix, Prunellae Spica, Ostreae
Testa, Laminaria Thallus, Sargassum exerted anticarcinogenic activity on
experimental murine colorectal cancer. Researchers from Sapporo
Medical University School of Medicine found L-trptophan in kelp. They
believe, this chemical benefits those at risk of breast cancer.
