Background: A healthy normal skin is essential for a person’s physical and mental well being. It is an important aspect of their sexual attractiveness, a sense of well being and a sense of self confidence. Vitiligo is an acquired depigmentation disorder of skin affecting 1% - 4% of the world population. Neither life threatening nor symptomatic (except that depigmented patches burn easily when exposed to the sun) the effects of vitiligo can be cosmetically and psychologically devastating. Because the disease is still not understood, there is a plethora of different treatments approaches, but they are largely unsatisfactory from patient’s perspective. Objective: To report the outcomes from oral use of an infusion of leaves of Solanum paniculatum L., Jacaranda brasiliensis and Sonchus oleraceus for treatment of vitiligo. Ethical issues: Study approved by the Research Ethics Committee of Hospital Federal dos Servidores do Estado do Rio de Janeiro (CAAE: 32143314.9.0000.5252). All participants confirmed the condition of volunteer by signing the Informed Consent Form. Methods: From October 2014 to October 2015 twelve subjects consumed daily four glasses (800 ml) of proposed phytotherapeutic preparation. Results: All subjects were highly satisfied about their outcomes. Total depigmentation was considered as a positive outcome because it is cosmetically acceptable. Total depigmentation was observed in presence of 80% or more of depigmenteted patches. Conclusions: The phytotherapeutic preparation proposed is effective on treatment of depigmenteted patches in vitiligo. 展开更多
