with the extracting agent being 30 v v aqueous ethanol which is commercially available from chemische fabrik dr hetterich k g fuerth germany in the following extracutum equiseti fluidum 1 1 this extract is prepared as follows the drug in the form of air dried in the shadow horsetail herb equiseti herba is cut into pieces of 6 cm u00d7 6 cm and is filled into a high grade steel percolator of a suitable size the extraction medium is prepared by mixing 50 parts by eight of 96 v v ethanol with 150 parts by weight of extraction grade water which corresponds to 30 v v aqueous ethanol the exhaustive percolation of the drug by means of the extraction medium is conducted at ambient temperature and ambient pressure 2 to 3 parts by weight of extraction medium depending upon the amount of the charge and the speed of percolation are required for 1 part by weight of drug the fluid extract is then stored at below or at 15 u00b0 c for 5 days to sediment suspended and clouding particles the extract is filtered and concentrated below or at 50 u00b0 c in a high vacuum to the end concentration of 1 part extracted drug to 1 part extraction medium another preferred starting material for the composition used in the inventive method is the juice which is squeezed from the fresh herb of equisetum arvense these preparations can represent partly the composition of the invention as such for example the juice from equisetum which is naturally also a composition can be applied as such onto a skin area to.
