IRB has developed an innovative range of products thanks to the exclusive HTN technology based on in vitro cultures of plant stem cells in highly controlled conditions.

STEMS are pure plant stem cells.

- CENTELLA ASIATICA

Available as titrated powder or 20% glycerine preparation, STEMS carry all the essential nutritive molecules (polysaccharides, amino acids, phytosterols) along with the active substances specific of each plant.

HTN ACTIVES are concentrated extracts titrated in active substances.
