Why is the long-soak or full extraction in the freezer method of making tincture called Green Dragon? Precisely because you don't do a quick wash just for infusing trichomes. That will result in a yellow liquid which can be used for making vapeable or smokeable concentrates. However, I'm convinced by my last batch of tincture, which sat in the freezer for 3 months and is a very deep green color, that a long soak produces a much stronger tincture. The chlorophyll and whatever other plant matter that got infused doesn't bother me at all. The greener, the better for tincture.
