Yes, I do the salad spinner thing too. I didn’t start off washing anything before processing but after I time I thought, well I ‘wash’ my vegetables, meaning I give them a rinse in cold water before I consume them so I guess I will do the same for plant matter that is being made into stuff.
I was hesitant with the resinous, really aromatic plants such as rosemary, calendula and gumweed but I figured they got a pretty good watering every time it rains and all I am doing is giving them a little swish, swish.
I do lay them out to dry and most of the time actually use a dehydrator set on very low, like 95 degrees. And I can tell you there is plenty of sticky left even after that treatment.
I unfortunately have had herbs get moldy because they did not dry long enough and that is disappointing, for sure. I even have a jar of chamomile that I would bet has started to ferment just by the aroma of it!
