Publications about hops
We ourselves are too small to undertake our own scientific studies on the properties of hops. In our skin care for people, hops are mostly a "nice to have", and we do not claim that our skin care in particular would in any way cure anything.
However, it is very exciting to read about what science finds for future medical possibilities with hops as an ingredient. We have collected a number of studies for those interested in delving deeper. It is important to remember that a study is not the whole truth, that just because something works in a certain context, in a lab, does not mean that it works in the human body and other contexts.
But as I said, exciting reading for those who are interested!
