Is it safe to take a remedy thats been made from a poison, like Belladonna (Deadly Nightshade)?
Its true that many remedies originally have been made from poisons. Remember that they have been prepared through a careful process of dilution and succession, so it is really only the energetic imprint of the remedy that we use. Homeopathic philosophy is based on the Law of Similars which states that a substance which can cause healthy people to get symptoms also has the power to cure those symptoms. Take for example Urtica Urens, or Stinging Nettle. If you touch this plant, it will make your skin itch intolerably and most likely break out in hives. However, if you were to take the plant and make a tincture out of it, you could apply it to the skin for fast relief of itching and hives!
