ABSTERSIVE (_comparative_ MORE ABSTERSIVE, _superlative_ MOST ABSTERSIVE)
* Cleansing; purging; abstergent. [First attested around 1350 to 1470.]
(Can we find and add a quotation of Francis Bacon to this entry?)
* 1603, John Florio, translating Michel de Montaigne, _Essays_, I.40:
If he cannot digest a strong and ABSTERSIVE drug, for to remove his evill, let him at least take a lenitive pill to ease the same.
