I have drawn your attention to the harmfulness of coffee only because I know only too well how much of humanity, especially the female kind, depends on this donkey fodder, when nothing could be more harmful to their nature than this drink. And hardly anything else would make the body, especially for the female one, more unreceptive for a good medicine than this coffee. Therefore, it must be carefully avoided in any state of sickness and during any cure, especially during this sun-homeopathic treatment, otherwise the medicine would not work at all. – The Healing Power of Sunlight, Chapter 4, Paragraph 3
