ABSTRACT:
Processes for polyphase fluid extraction of concentrated, active therapeutic components from parts of plants identified taxonomically as Symphytum, Taxus and Aloe species are described. The resulting products-by-processes are defined as Concentrated Fluid Plant Extracts (CFPE) of the respective plant types, where P can be S, T or A. The preparation process for CFPE includes multiple/sequential stages of diffusional transfer of the active constituents into liquid and/or vapor extraction phases under contact conditions of forced convection at controlled temperature and pressure. Therapeutic formulations based on CFPE including emulsions, aerosols, liposomes and controlled-release devices are presented. Treatment methods for a variety of skin conditions and complications of specific diseases are indicated.
