aspetta ho trovato qualcosa:
It is important to remember that all of the plant alkaloids will be removed, not just the psychoactive ones we are looking for. These may include some toxic compounds, and one should always have a good idea of what a plant contains and in what percentages before ingesting any extraction taken from it. Arundo donax for example, while containing DMT, also contains several other alkaloids which caused an allergic reaction in me when I ingested its extract. These unwanted compounds can be removed, but the process requires more knowledge of chemistry than I've learned to date.
