Garcinia cambogia may not be safe to use, according to WebMD. The extract may be dangerous if it is taken in conjunction with certain medications. In addition, it may have a negative impact on the liver.
Garcinia cambogia extract is a tropical fruit extract, which, on its own, poses no threat. However, since it has the ability to lower blood sugar and LDL, it may be dangerous to take in conjunction with cholesterol and blood sugar medications, reports WebMD.
The U. S. Food and Drug Administration also administered a warning in 2009 that many products containing garcinia cambogia had a negative impact on the liver, according to WebMD. However, it is unclear whether or not this was due to the fruit itself or because of other ingredients in these products.
