138. Fugo demonum: i.e. St. John's wort; hot and dry in the third degree. If it be boiled in wine or in water, it will cleanse the blood within the vessels, it will open the oppilation of the liver and spleen, it will provoke the urine and menstruation, and it will be beneficial against poison. If the powder of the same herb be put in wet wounds, it will promptly dry them. If the same herb be drunk in water for forty days, it will help with sciatica; the reason why it is called fugo demonum is that it drives away devils from whoever carries it with him; whoever holds it in his hand will have the gift of the gab, as we have seen.
