I think this is one of those situations where most of the people who care enough to debate are those with an economic interest. Like perfumers. Conflict of interest is possible I suppose, but Tisserand's rebuttal seems well reasoned regardless, and he provides a list of other rebuttals from other people.

> Does the 2013 rebuttal study in that link tell us anything about the safety of ingesting lavender extract?

No, only topical application, albeit in far greater quantities than is seen in typical usage.

> Wouldn't that involve much higher absorption than topical application?

No, not necessarily. Silexan is delivered in 80mg doses. Higher levels of the same chemicals can easily be delivered by common foods. For example, a dish that's well seasoned with thyme or coriander can easily contain far more than 80 mg of linalool, and a few other ingredients would easily provide the same terpenoid profile as found in lavender, just as if you were to eat a large amount of lavender oil. Lavender really isn't anything special.
