Panicking - was sleeping and woke up with a dry mouth (due to autoimmune condition) so reached into bedside drawer for Biotene Dry Mouth gel ... but mistakenly picked up Germolene and put some on my tongue. Realised what I'd done and went to rinse out my mouth. Lots of blood came from my tongue as I rinsed and rinsed. It's stopped bleeding but panicking a bit now as the blood was unexpected. Germolene tube just says for External use only, nothing more.
