Side Effects and Cautions
Kava has been reported to cause liver damage, including hepatitis and liver failure
(which can cause death).
Kava has been associated with several cases of dystonia (abnormal muscle spasm or
involuntary muscle movements). Kava may interact with several drugs, including drugs used
for Parkinson's disease.
Long-term and/or heavy use of kava may result in scaly, yellowed skin.
Avoid driving and operating heavy machinery while taking kava because the herb has been
reported to cause drowsiness.
Tell your health care providers about any complementary and alternative practices you use.
Give them a full picture of what you do to manage your health. This will help ensure
coordinated and safe care.
