ABSTRACT
The Cardio-Ankle Vascular Index (CAVI) is a physical examination method for indicating arterial stiffness non-invasively, as determined by measuring peripheral pressure waveforms on four extremities. We observed two cases in which CAVI was improved with the administration of Hachimijiogan.<br>Case 1 : a 79-year-old woman was suffering from pain of the tongue, dry mouth and numbness of the legs.Hachimijiogan improved the dry mouth and leg numbness, and weakened her tongue pain. R-CAVI and LCAVI before administration were 9.8 and 9.7. After 1-year of administration, her R-and L-CAVI decreased to 9.1 and 8.9.<br>Case 2 : a 77-year-old woman had cold sensation, numbness of the legs and urinary frequency. Six-months of Hachimijiogan administration improved these symptoms. Two-years' administration decreased her R- and L-CAVI from 10.2 and 10.1, to 9.9 and 9.2.<br>These two cases suggest the possibility that Hachimijiogan can improve CAVI in elderly people.
