Green external communication

Traditionally, Erythrina species have found use amongst different communities for various ailments. The bark of E. fusca and E. indica, for example, has been used for the treatment of fever, malaria, rheumatism, toothache, boils and fractures. Boiled roots of the same were taken internally as a remedy for beriberi. In Kenya, a concoction of dried bark of E. ahyssinica has been used for the treatment of trachoma (oral) and elephantiasis (external) and its roots against malaria and syphilis, while the pounded green stem bark is taken as an antihelminthic [3]. The water extract of flowers of E. americana have been used in Mexico for the treatment of insomnia. The resl of other documented traditional medicinal uses are listed in Table 1. 

FIGURE 7 Add-drop filter for a dense wavelength division multiplexed optical communication system. Multiple streams of data carried at different frequencies F1, F2, etc. (yellow) enter the optical microchip from an external optical fiber and are carried through a waveguide channel (missing row of pores). Data streams at frequency F1 (red) and F2 (green) tunnel into localized defect modes and are routed to different destinations. The frequency of the drop filter is defined by the defect pore diameter, which is different from the pore diameter of the background photonic crystal.
