Introduction: Onychomycosis is a fungal infection that triggers a poor quality of life for patients and despite being considered superficial mycoses, they are difficult to diagnose and treat. Essential oils have been used as a therapeutic alternative due to their antimicrobial and antifungal action due to the presence of phenolic components in parts of the vegetable used in the therapy. Objective: To evaluate whether the treatment of Podiatry with essential oils, with antifungal activity, in patients with onychomycosis enables nail reconstruction opening the perspective of studies to characterize its antimicrobial principles and techniques that promote the health and beautification of the feet. Methods: Care for patients with onychomycosis, and the control group is using traditional topical antifungal therapy available in the pharmaceutical market. The intervention group (a) used manuka essential oil and finally the other intervention group (b) using melaleuca essential oil. All participants were submitted to direct mycological and culture examinations to identify the fungal strain. Results: The tests performed using essential oils in the treatment of patients with onychomycosis showed that such substances triggered improvement, even if gradual of patients and with lower cost. Conclusion:The essential oils studied in the present study showed antifungal activity, opening a perspective of studies to characterize their antimicrobial principles for the treatment of nail mycoses and stimulate the development of new forms of treatment containing phytopharmaceuticals.

Brazil holds the largest reserves of natural resources in the world, being an international highlight in biological diversity, it is estimated that 20% of the total species already inventoried are in Brazil. However, the literature indicates that there are few studies related to the use and development of technologies from native plants, mainly in the cosmetic industry. This work aims to develop a cosmetic product based on the hydroalcoholic extract of the bark of Myrciaria Cauliflora (jabuticaba) and carry out its quality control. As an extraction methodology, cold maceration was used, with distilled water as the extracting liquid. Three different concentrations of extract incorporation were tested [1.5%], [3.5%] and [4.0%], in triplicate, and centrifugation tests, temperature stress, organoleptic assays, pH, density, and spreadability. All samples were stable in most tests, with changes being observed in centrifugation tests (creaming) in all samples, and temperature stress at 70°C, where there was flocculation of concentration samples [4.0%]. The moisturizer obtained from the hydroalcoholic extract of Myrciaria cauliflora bark has a potential cosmetological profile, being an economical alternative for the cosmetic industries due to the possible reuse of waste from the food industry, and encompasses the new market of consumers who value the ecological footprint of companies.
