![]() 1 The cashew culture is one of the main agronomic activities in Northeast Brazil and almost the whole production is concentrated in the states of Ceará, Piauí, and Rio Grande do Norte. It is a native plant of Brazil and the fruit consists of a cashew nut (the true fruit) and a cashew apple (pseudofruit), which has excellent nutritional and sensory properties. The cashew tree ( Anacardium occidentale L.) belongs to the family Anacardiaceae. The results suggest that UNCAJ presents a greater therapeutic activity due to a synergistic effect of its phytochemical components, which improve the immunological mechanisms as well as an optimal balance between ROS and antioxidants leading to a better wound healing process. Despite of higher antioxidant capacity, RCAJ did not promote better anti-inflammatory, and healing responses, which may be explained by the fact that treatment increased antioxidants level leading to a redox “imbalance” turning down the inflammatory response modulation exerted by reactive oxygen species (ROS). Moreover, UNCAJ also showed the best result for wound contraction (86.31%) compared to RCAJ (67.54%). ![]() The UNCAJ presented the main anti-inflammatory activity by a significant inhibition of ear edema (66.5%) when compared to RCAJ (10%). Both antioxidant content and total antioxidant activity were higher in ripe cashew apple juice (RCAJ) than in unripe cashew apple juice (UNCAJ). Edema thickness was measured and skin lesions were analyzed by planimetry and histology. Swiss mice were treated with cashew juice by gavage. Those were evaluated in murine models of xylene-induced ear edema and wound excision. ![]() Juices from ripe and immature cashew apples were analyzed for antioxidant, anti-inflammatory, and wound-healing properties. Thereby, this study evaluated the antioxidant capacity, anti-inflammatory, and wound-healing activities of cashew apple juice. In spite of being well known for its important antioxidant properties, the cashew apple has not been thoroughly investigated for its therapeutic potential. Cashew apple is a tropical pseudofruit consumed as juice due to its excellent nutritional and sensory properties.
