Potencial Antifúngico do Extrato de Arnica Brasileira (Lychnopora ericoides) e Alecrim (Rosmarinus officinalis) no Controle de Malassezia furfur capilar

Abstract

This exploratory study aimed to assess the antifungal potential of Brazilian Arnica (Lychnopora ericoides) and Rosemary (Rosmarinus officinalis) extracts against the fungus Malassezia furfur, focusing on their possible application in combating capillary oiliness. Malassezia furfur is a fungus commonly associated with seborrheic dermatitis and other skin disorders, including excessive capillary oiliness. Brazilian Arnica and Rosemary extracts emerge as potential therapeutic agents due to their antifungal and oil-regulating properties. Brazilian Arnica and Rosemary were chosen for their phytotherapeutic properties and the antifungal potential previously observed in related research. Methods included obtaining the extracts through specific procedures, such as collecting and drying the aerial parts of Brazilian Arnica and macerating the Rosemary leaves. Certified strains of Malassezia furfur were used to determine the Minimum Inhibitory Concentration (MIC) of the extracts, demonstrating remarkable antifungal activity. The results indicated that Brazilian Arnica and Rosemary extracts exhibited properties that may contribute to controlling sebum production on the scalp. This dual benefit, combining antifungal activity against Malassezia furfur and the ability to control capillary oiliness, suggests that these extracts have potential as ingredients in hair formulations. These results highlight the importance of these extracts as multifunctional therapeutic agents in the treatment of scalp skin disorders. Further research is needed to fully explore their benefits and potential applications in dermatological clinical practice.
