         25 . A method of applying a cosmetic, comprising
 applying a cosmetically effective amount of a cosmetic composition to the skin of a human subject, wherein the cosmetic composition comprises aloe and an aloe-extracted component of a cardiac glycoside plant species.   
     
     
         26 . The method of  claim 25 , wherein the cardiac glycoside plant species is  Nerium oleander.    
     
     
         27 . The method of  claim 26 , wherein the cosmetic composition comprises a dermal agent. 
     
     
         28 . The method of  claim 27 , wherein the dermal agent is a cream or a lotion. 
     
     
         29 . The method of  claim 28 , wherein the dermal agent is a face lotion. 
     
     
         30 . The method of  claim 27 , wherein the dermal agent is an emulsion, an oily ointment or an aqueous ointment. 
     
     
         31 . The method of  claim 26 , wherein the cosmetically effective amount is effective to moisturize human skin. 
     
     
         32 . The method of  claim 26 , wherein the cosmetically effective amount is effective to soften human skin. 
     
     
         33 . The method of  claim 25 , wherein the cardiac glycoside plant species is  Nerium indicum.    
     
     
         34 . The method of  claim 25 , wherein the aloe-extracted component comprises a cardiac glycoside. 
     
     
         35 . The method of  claim 34 , wherein the cardiac glycoside is oleandrin.
