As I have mentioned elsewhere - I have one of the oldest and lastest Pacific Yews
trees in my area - certainly with in walking distance or even within walking distance of anybodies house I know personally (and I live in a rather small expanding yet shrinking community). I think it is my responsibility to learn about (and from) this tree. It is a shade loving evergreen and its bark has been used to synthesize effective cancer drugs.
Pacific Yew is a tree that is naturally giving of its bark. Much like and even more so than western red ceder and madrona. It naturally sheds its bark in small sheets which pill bugs and others often explore.
Once a year for about a month I'm harvesting some of these dead sheets. I go for the ones that have a bluish lichen growing on them. Those ones grind up into a nice fine smooth powdery fiber in the palm of your hand with some thumb pressure. I crush dried
nettle leaves with it and steep for ten minutes.
I make no claims about knowing anything about the medical value of the actual bark. It is just a renewable resource I have available which begs to be harvested respectfully. It's getting cold and I do like tea and it would be rude to refuse an obvious
gift.
