Re: Sycamore smoke to control varroa mite
I wonder if this is the same as the ficus that is a common houseplant.
I only browsed the article to find the table with the components listed. I am not trying to be coy, but the answer to the toxicity question is: it depends. It depends on the inherent toxicity and the level of exposure. Toxnet lists information related to the toxicities of many substances, so that would be a starting point.
A lot of what were reported are hydrocarbons and the others are alkaloids. I am positive that those are not the only components of the raw leaf and that they are only the components that were isolated and identified.
The authors of the study have big problems with proper protocol. The substance bis(2-ethylhexyl) phthalate is not naturally occurring. It is a plasticizer found only in manmade plastic objects, not plants (well, maybe chemical plants ). If they're leaching that into their samples, which other reported components are present due to sloppy lab habits?
