Le défi de la mise en culture bio d'une plante aromatique et médicinale dans un contexte pharmaceutique : produire l'immortelle d'Italie (Helichrysum italicum subsp. italicum) dans le respect de la politique qualité du groupe Pierre Fabre

Abstract : The essential oil (EO) of everlasting (Helichrysum italicum subsp. italicum) is subject to increasing demand from aromatherapy users. Naturactive asked Pierre Fabre Agronomy (AFP) to produce, in the Tarn (France), 90 kg / year of this organic EO, which has led to study its cultivation in compliance with the Quality policy of PFA. It is a complex one, because PFA is committed to a stringent environmental policy and the GACP (Guideline on good Agricultural and Collection Practice for herbal medicinal products), in addition to organic rules. The inventory of (regulatory, agronomic, technical and economic) constraints has led to: improved regulatory tools of quality monitoring; the creation of a cultural process (CP); a mechanized plantation. The created CP, consistent with PFA's constraints, is innovative for everlasting: a 7-year perennial crop, applied in double rows (to optimize the linear footage), on mound (to avoid water stagnation), with mulching (to facilitate AB maintenance), and with dripping irrigation (for pre-vegetative/ post-harvest stages). Distillation will be done, after mid-June harvest, on the whole flowered fresh plant. The plantation has resulted in 5.3 ha of operational crop (density: 14,300 plants / ha), with a production estimate of 42 kg of EO/year starting from 2017. Technical issues still need to be solved for 2015: adding liquid fertilization, harvest process and distillation. The climatic impact on the quality of the OE and the CP performance should be evaluated after the first harvest.
