This patent relates to a novel phytotherapeutic compound for topical use, specially formulated for the treatment of burns. The innovation lies in the use of a formulation that combines passion fruit leaves (Passiflora sp.) and refined pork fat, providing a natural and effective approach to the management of skin burns. Passion fruit leaves are processed by infusion to extract flavonoids, known for their anti-inflammatory and antioxidant properties, which reduce inflammation and oxidative stress in damaged tissue, facilitating healing. Refined pork fat, chosen for its rich composition of essential fatty acids and its emollient properties, serves as the base for the ointment, helping to absorb the active ingredients and to form a protective barrier that minimises transepidermal water loss and protects against infections. The method of obtaining the compound involves frying the fat to extract lipids, followed by filtration for purification. Subsequently, passion fruit leaf extracts are combined with the purified fat and the mixture is evaporated until it reaches the appropriate consistency for an ointment. This composition not only accelerates the healing of burns, but also significantly alleviates the pain and discomfort associated with such injuries. The compound offers an effective and safe alternative to conventional burn treatments, standing out due to its simplicity, efficacy, and use of natural ingredients, making it particularly valuable in regions with limited access to medical resources.
