Intentionality - "is at the heart of knowing. We live in meaning, and we live 'towards,' oriented to experience. Consequently there is an intentional structure in textuality and expression, in self-knowledge and in knowledge of others. This intentionality is also a distance: consciousness is not identical with its objects, but is intended consciousness" (quoted from Dr. John Lye's website - see suggested resources below).
Central to the treatment of unbalanced humors was the use of herbs. Specific herbs were used to treat all ailments simple, common and complex etc., from an uncomplicated upper respiratory infection to the plague. For example, chamomile was used to decrease heat, and lower excessive bile humor. Also, arsenic was used in a poultice bag to 'draw out' the excess humor(s) that led to symptoms of the plague. Philip Moore, who wrote on the hope of health , and Edwards, who wrote Treatise concerning the Plague discuss how these herbs are helpful in curing physical disease. They also discuss the importance of maintaining an herb garden.
