For children

Natural substances — explained for children

The same research as in the knowledge section, told for children aged 8 to 12: simple words, pictures from everyday life, one experiment per page.

The substances and therapies

Every page has four parts: What is it? Where does it come from? What do researchers study? And an experiment to try at home.

For parents and teachers

The children's pages rest on the same data as the knowledge section for professionals: our study database. Nothing is invented; where research is thin, the page says so in children's words.

Each children's page is also the script of an audio version.

Every statement on this page carries its evidence tier — proven, plausible or hypothesis — and leads to the original work. The decision in the individual case rests with the practitioner; we provide the connections.
