Hi, Blueduck. No guarantees that ear candles can help, but they might. Depends on what is meant by "plugged" I guess. If you mean the kind of effect you get on an airplane before your ears pop, yes, could help with that at least temporarily because of altering the pressure around the ear drum. Underlying cause is the main consideration here. I am not a doctor or an ear specialist and am not qualified or authorised to give medical advice. There are various contraindications to use of these candles, so before trying ear candles the instructions should be read carefully. For example, if someone currently has or has had a perforated eardrum they need to be sure that this has healed before using the candles and should seek medical advice if necessary. If there might be some kind of infection in the eustachian tube, they should definitely see a doctor as spread inwards of such an infection can be serious. I don't really want to make specific suggestions to individuals, because it would be better to see a therapist who can take a proper case history, but hope that this helps in a general way.
