Well, we have to remember that the glucan is polysaccharide and the use of similar substances in medicine started somewhere around 1890. But in that time, people didn’t know what they had, or, what they were trying to do so really glucan show up on the scientific radar somewhere around 1960.
And It came in several waves; five years of intensive research and people stopped thinking about it and started again in the 70s and 80s so it and it keeps coming.
