Report No.:  64
 
Type of Conclusion:  1
 
ID Code:  9000-29-7
 
Year:  1975
 
CFR Section:  There is no CFR citation.
 
SCOGS Opinion:  The literature on the biological activity of gum guaiac indicates that it is a substance of very low acute toxicity. A number of short- and long-term feeding studies in experimental animals at levels orders of magnitude greater than those to which humans might be exposed indicate the abscence of chronic effects. Daily ingestion by human subjects for nearly four years resulted in no observable adverse effects. The Select Committee has found no indication that gum guaiac is currently used as a food ingredient. In the light of the foregoing, the Select Committee concludes that: There is no evidence in the available information on gum guaiac that demonstrates, or suggests seasonable grounds to suspect, a hazard to the public if it is used as an antioxidant at levels compatible with current limitations.
