Smell is the sense most closely tied to memory, a fact that students exploit by studying in Italian restaurants before dipping math tests in marinara. Sniff out memorable scents with today’s Groupon to Antica Farmacista. Choose between the following options:

• For $29, you get a 250-milliliter Home Ambiance fragrance in your choice of scent (a $62 value).
• For $25, you get $50 worth of products.<p>

Hyped by a cornucopia of media outlets, Antica Farmacista extends the reed-diffuser concept it brought to the United States in 2003 to a range of fragrant products for the home and body. Treat an obedient den or stuffy bathysphere to an antique-inspired apothecary bottle filled with one of 18 signature fragrances. Aria arrives loaded with citrus notes, green accents, and floral treble clefs, and the vanilla, bourbon, and mandarin collection mixes a trio of heady scents into a singularly rich aroma. Each bottle disseminates its nasal niceties through an open neck with white-birch reeds.

Antica Farmacista continues its aromatic mastery with other offerings for the home and body. Douse abodes in room spray ($28), or air out bods with a bath and shower wash ($25), each available in a selection of the odor outfit’s signature fragrances.
