120. Es ustum: i.e. burnt copper; hot and dry in the fourth degree; it has the ability to purge the melancholic humour principally; it has the attenuating, consuming and dissolving virtues, and, for that reason, it is put into the dissolving plasters such as Apostolicon and the likes. If a powder be made of it for festering wounds, it will consume the proud flesh and comfort the wounds. If the same powder be mixed with honey and soap, and put into the wounds, it will help with every suppuration and ulceration of the wounds. If powder of burnt copper be given with oximel or with warm water, it will powerfully purge the melancholic humour below and above.
