MIT researchers looked at why some scientific data shows that ginseng promotes blood vessel growth while other studies report the opposite.
Chemical fingerprints of four different varieties of ginseng—American, Chinese, Korean and Sanqi–show that each has different proportions of two key ingredients. Additional studies showed that a preponderance of one ingredient has positive effects on the growth of blood vessels; more of the other component tips the scale the other way.
The study, they say, supports the need for "regulations standardizing herbal therapies through compositional analysis." While that statement is sure to piss off a lot of people, the researchers also believe that reverse-engineering ginseng could eventually lead to the development of new wound-healing compounds.
