Keys among 500 remedies for investigations, explorations and teaching purposes. [Note].
Some plants, germs, and chemicals are poisonous, even deadly. Not all of them are marked off as so below. So better take heed. Homeopathic germ preparations (called nosodes) around the 30c potency (D30 also) might perhaps be too low to be safe. For minerals, plants and the rest, the 6c or D6 potencies are considered safe.
