Disclosed are safe, simple and effective broad-spectrum treatments for halitosis and other microbial infections of the nondental upper respiratory tract useful to treat bacterial and other microorganism species, including anaerobic bacteria. Electromagnetic radiative energy including visible, and optionally, thermal, RF and/or microwave wavelengths, is topically applied to internal surfaces of the upper respiratory tract to destroy or incapacitate superficial microorganisms without the use of antibiotics. One useful apparatus is a handheld energy applicator having a light output head suitable for treating the back of the tongue and the tonsils and which may be interchangeably provided with extensions to reach the sinuses. The energy applicator can be supported and guided by a mounting device held between the subject's teeth, if desired. Useful embodiments of the invention include preparative treatment of the target surfaces with a photosensitizing agent such as an oxidizing agent or a complementary stain. Optionally a pre-treament procedure may be employed to remove detritus and microfloral overgrowths that may mask more deeply resident target microorganisms. Novel treatments include treatment of halitosis by destruction of bacterial species associated with halitosis, such as Atopobium parvulum, by application of non-ionizing radiative energy to the tonsils and the back of the tongue. Another embodiment comprises a candy bar incorporating a halitosis treatment lamp disposed within the candy.

A hemostatic tissue sealant sponge and a spray for acute wounds are disclosed. The sponge comprises hydrophobically modified polymers that anchor themselves within the membrane of cells in the vicinity of the wound. The seal is strong enough to substantially prevent the loss of blood inside the boundaries of the sponge, yet weak enough to substantially prevent damage to newly formed tissue upon recovery and subsequent removal of the sponge. In examples, the polymers inherently prevent microbial infections and are suitable for oxygen transfer required during normal wound metabolism. The spray comprises hydrophobically modified polymers that form solid gel networks with blood cells to create a physical clotting mechanism to prevent loss of blood. In an example, the spray further comprises at least one reagent that increases the mechanical integrity of the clot. In another example, the reagent prevents microbial infection of the wound.
