Ginkgo supplement does not contain colchicine, say experts
Recent research has proved that ginkgo supplements do not contain the toxic alkaloid colchicine as was suggested by a study. The study, “Identification of Colchicine in Placental Blood from Patients Using Herbal Medicines,” by Petty et al., was released on the American Chemical Society’s website in 2001.
The authors of the study, which was not formally published, warned that consumption of ginkgo supplements posed risks to developing fetuses of pregnant women. The study was based on an analysis that they believe revealed the presence of colchicine in ginkgo.
Independent analyses of raw powdered Ginkgo biloba and ginkgo extract have disputed the findings of the study.
Validity of the conclusions of the study published by the media and the research methods used by the researchers were questioned by herb experts.
Some experts hinted that the investigators took a non-toxic ginkgo compound for colchicine.
They said since the ginkgo compound is similar in structure to that of colchicine, and the researchers did not feel it necessary to carry out a test to distinguish it colchicine.
“Ginkgo simply does not contain colchicine,” HRF President Rob McCaleb was quoted as saying.
“These scientists should have done their homework before submitting their erroneous conclusions for publication,” he added.
