Japanese knotwood along with many of the other tinctures on this site have been quite literally life saving. Excellent quality.

I really love all things woodland essence. I hav e two suppliers that I buy my tinctures from, one being WE. They have integrity, clean tinctures and i can tell they care. I also appreciate the effort in packing the materials- i love the dried roses they include in their packaging, lovely smell. Please support this maker, they are helping the world be a better place.
