CHAP. III.
VERTIGO, is a disease, * 1.1 wherein the pati∣ent doth imagine, that his head and all other things, doth turn round, and the brain is so affected, that the eyes grow dark and dim, that if the patient be not stayed up, he falleth to the ground.
The cause, is, either of the brain, * 1.2 being distem∣pered, and evill-affected, or of the mouth of the stomack offending the brain. The brain it self is evill-affected, when as a grosse and tough humour is contained in it, from whence a vapo∣rous and windy spirit, being resolved by weak heat, is moved inordinately about the brain. The mouth of the stomack doth affect the brain, when through corrupt homours, being gathered abundantly in it, vaporous and win∣dy exhalations are carried up to the brain, and so turn about the animal spirits contained in it.
For the cure, the first intention is, * 1.3 to open a vein, drawing away a little blood at a time, * 1.4 if nothing forbid it: then to purge with a dosse of head-pills, as. Pilularum cochiarum, ʒ.j. f. pill. 7. * 1.5 when the body is well purged, take this ster∣nutament following, as much as will lye upon a half-peny piece at a time, in a morning fa∣sting; snuffe it up into your nostrils, many have been perfectly cured with this Receipt onely.
