Standardized extracts are pharmacological products. They imply that the material presence of specific molecules are the only requirement to activate tissue receptors or molecular pathways in order to achieve the healing process. This is how drugs work.
Our tinctures are full spectrum plant products representing the whole plant (root, seed, leaf, flower). Historically, all plant medicines have been whole plant/plant part medicines. The part only has meaning when it is in the context of the whole.
The Vis (or Viriditas) of the plant is conveyed in wholeness not in fractioning.
Holistic medicine is based on this understanding.
