[Therapeutic effects of borneol-walnut oil in the treatment of purulent otitis media].

170 patients were treated with borneol-walnut oil of various concentrations, and the controls (108 patients) were treated with neomycin compound. As a result, the total effective rates were 98.06% and 84.26% respectively (P less than 0.001). This indicated that the therapeutic effects of borneol-walnut oil for the treatment of purulent otitis media were superior to that of neomycin compound. The most optimal concentration of borneol-walnut oil was 20% through clinical and laboratory observations. Due to its simple composition, significant therapeutic effects and nontoxic reactions, the borneol-walnut oil has been proved a promising external remedy for the treatment of purulent otitis media.
