1. A method for extracting cardiac glycosides, comprising: mixing a plant related to a plant species containing cardiac glycosides with aloe under conditions selected to obtain an extraction mixture； conditioning said extraction mixture under conditions selected for extraction of cardiac glycosides from a plant related to a species plants containing heart, thereby obtaining a conditioned extraction mixture, while the specified conditioned extraction mixture contains a residual amount of a plant species containing cardiac glycosides and a mixture of cardiac glycosides and aloe； separating at least a portion of the mixture of cardiac glycosides and aloe from the residual amount of a plant species containing cardiac glycosides and thereby obtaining an extract containing cardiac glycosides and aloe, wherein said extract containing cardiac glycosides and aloe contains cardiac glycosides extracted from said plant belonging to a plant species containing cardiac glycosides； and wherein said extract containing cardiac glycosides and aloe, essentially does not contain residual plants belonging to the species of plants containing cardiac glycosides. 2. The method according to claim 1, characterized in that the plant belonging to the species of plants containing cardiac glycosides belongs to the family selected from Apocynaceae, Brassicaceae, Plantaginaceae, Euclidean (Ruscaceae) or Hyacinthaceae (Hyacinthaceae ) .3. The method according to claim 2, characterized in that the plant containing cardiac glycosides belongs to the species Oleander ind1.
