Extraction for organic aromatic and medicinal plants

Plants are selected as soon as their content in active ingredients is the highest. In order to obtain a better extraction plants are cut immediately before soaking. We maintain strict controls over plant harvest and growing crops thanks to specifications the farmers must comply with. Our experience over 20 years in the field gives us a thorough knowledge of the various active ingredients and the specific plant parts which correspond to them.

These active ingredients are preserved through a unique extraction process invented and set up by Thierry Bizouard. This process has received the Artinov award in 2007.


Steam distillation	Extraction plant

With our geographical location, we offer our customers extracts obtained from natural Vercors spring water. This pure water is used directly for our preparations after softening.

Lay out of production process

At the end of each extraction, plant waste is recycled into compost.

Extraction by maceration in solvents

Extracts are obtained by plant maceration in a suitable solvent, such as water, alcohol, oil or glycerin. We designed a custom extractor for maceration, which won us an Artinov award. It allows us to extract a maximum of active ingredients from plants. The macerations can be carried out cold or hot. The maceration is then pressed and filtered between 0.2 µm and 250 µm.
All our extracts can be packed in containers ranging from 0.5 litres up to 1 000 litres.
