If you plan on consuming your cuts, the sooner you cut them the better. We can reasonably suspect that allowing cuttings a month or so's rest in a cool, dark and dry (as in, not damp) place will have a positive effect on their alkaloid content.
IME, it's best to keep the cut plants pretty much dry throughout the winter - just give them a little rainwater if they start looking excessively shrivelled; watering of intact specimens is dependant on temperature, light levels and, inversely, relative humidity.
“There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
― Jacques Bergier, quoting Fulcanelli
