The bark is antacid, antipyretic, antiseptic, antitussive, expectorant, odontalgic. A tar (or creosote), obtained by dry distillation of the branches, is stimulating and antiseptic. It is used internally as a stimulating expectorant and externally as an application to various skin diseases. The pure creosote has been used to give relief from toothache, but it should not be used without expert guidance. The plant is used in Bach flower remedies - the keywords for prescribing it are 'Intolerance', 'Criticism' and 'Passing judgements'. Source: https://pfaf.org/
