         8 . Method according to  claim 6 , further comprising the step of
 d) freeze-drying of the acquired extract or   e) vacuum extraction of the acquired extract.   
     
     
         9 . Method according to  claim 6 , wherein solvents and/or mixtures of solvents are used as the extraction medium, the solvents being selected from the group comprising water, table salt solution, low-molecular-weight alcohols, acetone, esters, and ethers. 
     
     
         10 . Method according to  claim 9 , wherein 0.9% table salt solution, 90% ethanol, or 70% isopropanol is used as the extraction medium. 
     
     
         11 . Method according to  claim 6 , wherein the low-THC variety of  Cannabis sativa  subspecies  sativa  is preferably the variety Futura 75. 
     
     
         12 . Pharmaceutical, cosmetic or dermatological composition, comprising a plant extract made of the flowers and/or flower-proximal leaves and/or stalks and/or roots and/or seeds of one and/or multiple low-THC varieties of  Cannabis sativa  subspecies  sativa , produced according to the method of  claim 6 , and further pharmaceutically suitable aids and/or additives.
