Glechoma longituba is a common
medicinal plant that is common in wet and sunny land. This
plant is used to treat various illnesses including
jaundice and
edema. But,
ingestion of the
plant can cause severe
pain and swelling on
lip and
mouth. We experienced three cases that had oral
pain and sensory change after
ingestion of G. longituba, which we
report with a
literature review.
