Abstract

The aim of this study was to investigate the wavelength-dependency of chromotherapy effects on cutaneous Leishmaniasis parasite growth. Chromotherapy uses visible range radiations to improve healing; however, its effects on parasite are not well understood. Leishmania Tropica was irradiated using seven (7) different wavelengths of visible region. Optical density was observed, which showed that red colour (644 nm) wavelength inhibited the growth of parasite while other colour wavelengths also affected the growth of parasite. It is, therefore, suggested that as red colour inhibits the growth of parasite so patients suffering from l.tropica can be treated with the application of red colour.
