Desperately seeking help for our daughter who's been dry coughing for 4 weeks and getting worse. Been to Sanitarium where the diagnosis was allergic airway and ineffective medication given. Been through the Chinese medicine gauntlet as well, boiling every stick and leaf known to stop is Sue Jameson in Central for more scented oils and chanting (joking...sort of)...we are at our wits end here looking for some effective treatment...anyone??
