Hi Dicky, Yup, urine will remove makeup but not so good on waterproof mascara. Yup you can put urine drops in your ears and sniff it up your nose. Tinnitus often responds well to homeopathic Aconite 30, but I don't know if you would be able to do it with UT. You would have to do the Aconite when you had no tast or smell of the urine, or the body would not detect and act on the stimulus of the Aconite Love and Light, Deotima.
