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