ABSTRACT:
Processes for polyphase fluid extraction of concentrated, active therapeutic components from parts of selected medicinal plants which have been identified chemotaxonomically are described. The resulting products-by-processes are defined as Concentrated Fluid Therapeutic Extracts, CFTE, of the selected plant types, where T represents a specific herbal plant family such as Symphytum, SYM, Taxus, TAX, Panax, PAN or Aloe, ALO. The process disclosed for CFTE preparation includes multiple/sequential stages of diffusional transfer of bioactive constituents from plant tissue into liquid and/or vapor extraction phases under contact conditions of forced convection at controlled temperature and pressure. Therapeutic formulations based on CFTE including emulsions, aerosols, liposomes and controlled-release devices are presented. Treatment methods for a variety of mammalian diseases and conditions and complications of specific diseases are described.
