Phrenitis is cured by sleep induced by the agency of an infusion of peucedanum1394 in vinegar, poured upon the head, or else by the juice of either kind of anagallis.1395 On the other hand, when patients are suffering from lethargy, it is with the greatest difficulty that they are aroused; a result which may be effected, they say, by touching the nostrils with juice of peucedanum in vinegar. For the cure of insanity, betony is administered in drink. Panaces1396 brings carbuncles to a head, and makes them break; and they are equally cured by powdered betony applied in water, or else cabbage leaves mixed with frankincense in warm water, and taken in considerable quantities. For a similar purpose, a red-hot coal is extinguished in the patient’s presence, and the ashes are taken up with the finger and applied to the sore. Bruised plantago1397 is also used for the cure of carbuncles.
