In addition to its Nanotheranostics project where two medicinal plants have been selected to produce its products, Torskal devotes part of its research activities to the screening of new plant species available on Reunion Island and to the development of new nanotheranostic solutions in response to societal expectations.
Prior to the selection of the plant, we considered the possible in vivo side effects induced by the plant extracts either by dissociation of physisorbed molecules during the vectorization or by nonspecific targeting of the tumor area. The choice of medicinal plants was done according to the medicinal property of the plant used, and ecological criteria. The Asteraceae plant herein studied is well known in traditional medicine in Reunion Island. In external and internal use this plant is recommended for skin problem as eczema. We focused on ecological or green extraction of natural products which based on the design of extraction process that will reduce energy consumption and eliminate petroleum solvents, while ensuring a safe and high-quality extract.
