My experiment with "cuttings" (and a question or three)

Yes, that's where they got the name.

The salicylic acid is derived from the bark of the willow and used quite a bit in skin care products.

Commercial aspirin is Acetylsalicylic Acid. Also originating from the willow. In days of yore (actually, days of mine ) the herbalists/witchdoctors used the extract from the bark of the willow. Just as many of the 'medicines' we use now are derived from the plants in our garden or growing wild.

I think Zigs put up a thread about those things
