Hi Lotte,
Great research. Maybe you found this article when you were looking for the info? https://mens-en-gezondheid.infonu.nl/leven/40459-estragol-basilicum-en-pesto.html I found it interesting.
This seems to be a classic case of researchers extracting one chemical constituent from a plant, an isolate, and then testing that at high doses on “animal models”. All round not very helpful – although interesting! And of course we know that the dose is what matters.
On Basil – when I was a volunteer gardener at De Hortus, a few of us liked to experiment with strong teas from some of the herbs. One day we tried Basil – and got high. (this was a personal thing, the Hortus knew nothing of it!) It was quite an impressive high too. Again, the dose makes the difference. Anyway – thanks again for the research!
