Gemmoderivatives, also known as glycerinated macerates (MG) or Meristemoderivati, are hydroglycerohydric macerations obtained from young plant tissues at the initial stage of development, collected spontaneously in ecologically undraged territories or from organic crops. The parts used - buds, rootlets , sprouts, lymph - as soon as they are removed, they are carefully checked and sent to the extraction phase with a solvent mixture of water, alcohol and glycerine. The phyto-derivative obtained contains all the active ingredients characteristic of meristems and performs their complex health activities in the most effective way.
