Haly's Lohoch.
Take Haly's Powder, fresh made up half an ounce; Diacodium 1 ounce and half; or as much as is sufficient, mix
It most potently incrassates, obtunds Acrimony, gratifies the Parts, quiets a tickling Cough, and is precisely appropriated to a thin Catarrh. It's good for Consumptive People. I don't deny; but 'tis so only secondarily, namely as it appeaseth a guttural Cough, which, by continual Succussation, useth to agitate the Lungs, and pump out acrid Serum into them; but it does not primarily affect the Lungs, into which it cannot descend. For the Asperia Arteria (by the wise and careful Providence of Nature) is lin'd with a Nervous Membrane, of so exquisite a Sense, that it cannot admit of any thing to enter it, but meer Air, not one drop of clear Water, no so much as Spittle it self (though a Liquor so near a kin to what the Glands spew into it) without grievous Offence, and resistance, and Coughing violently, and Struggling , and almost Strangling, 'till its thrown out again.
Let it be then an establish'd Article, that no Eclegme, or any other Medicine (except Vapours and Fumes) can be sent directly and immediately into the Lungs. And whatsoever the Remedy be that affects them most (as Balsamics and Volatiles) its convey'd mediately only, by the Curricle of the Blood, into the Tracheal Ducts; and Nature never knew any other way.
