Extraction et valorisation des huiles essentielles de Ricinus communis L pour l'industrie pharmaceutique et cosmétique

Abstract

Ricinus communis, commonly known as castor, is a medicinal plant well known for its therapeutic properties and is widely distributed across various regions of the world. Its essential oil is extracted from the seeds and is rich in ricinoleic acid. It exhibits anti-inflammatory, antimicrobial, and wound-healing properties. In the pharmaceutical field, castor oil is used as a laxative, a carrier of active compounds, and in the manufacture of certain medications. In cosmetics, it is used in creams, ointments, hair oils, and skincare products due to its nourishing and regenerative effects. The valorization of this oil supports local plant resources and promotes innovation in natural product development. In this study, we first extracted the oil as the primary product, then developed a cream formulated for treating eczema and reducing skin inflammation. This cream was tested on several individuals, and the results showed significant effectiveness in relieving symptoms and improving skin condition.
