Thanks, Maurice, I do bow to and appreciate your knowledge of the literature on Colchicine, though the German citation does not provide an English translation, and restricted access to both papers does not help me with details or understanding the meaning and results of the follow-up Hemerocallis tests (is it possible to translate or quote them out a bit, to show how the abstracts or research results indicate an absence of Colchicine in daylily flowers, and how that is found by the mosquito tests?).
So, I agree with what you say about the validity of research findings - though I'm not yet comprehending the particular focus or lab methods used for these two papers (for example, were they testing all parts of each plant type, including flower parts, or was that found to be superflous given the available method?) or able to see the data for daylilies reported in these two trails, due to the German-language and Abstract-only limitations.
I guess I'll leave my previous post and links up for now ... out of an abundance of caution (or an abundance of ignorance) and edit the post to use more qualifying language ... until I can grasp the answers to such questions. But, I trust your take on those referenced papers; I'm very glad that there is further discussion and research being brought to bear, and hope to learn enough to know whether I should pull the information on daylily flowers in my previous post. I'm very encouraged to hear that you may be able to facilitate additional information through a researcher familiar with Colchicine, thanks!
