Abstract
This invention relates to use of cyclodextrins to complex urushiols to protect against and to treat irritation arising from exposure to urushiols. Cyclodextrins, particularly gamma-cyclodextrins, are capable of binding strongly to urushiols and can be used effectively to prevent irritation of tissue that is exposed to urushiols. Cyclodextrin-urushiol complexes can also be used to desensitize against urushiol. Compositions containing cyclodextrin/urushiol complexes may be provided as tablets for buccal administration in dosages sufficient to induce desensitizing response.
