Doctor Mentioned Ashwagandha As "Building" / "Cumulative"...? My doctor recommended Ashwagandha to me after quitting alcohol (to help manage stress). I told her I didn't feel much of an effect from it, however, she mentioned to continue taking it as it's "cumulative". 

I thought this was a standard drug / adaptogen with a standard half life with effects that wore off, etc. Are cumulative doses actually going to feel different overtime than if I took it just a few times? Whatever I'd feel from each dose I'd assume would be the same.

How are there cumulative effects? There aren't SSRI properties or anything like that so I'm very confused. I don't think my doctor is correct on this.
