The Routine

More than two packets a day

Cellavara Core is designed as a complete daily system: two packets timed to how memory works, plus a few simple habits that published research links to better learning, sleep and recall. The habits are optional and free.

  1. Morning

    Take the AM packet with breakfast

    Then put your hardest learning early in the day. When you study, test yourself instead of rereading: recalling information is one of the best-studied ways to keep it.

  2. While you learn

    Optional: add a scent cue

    Not required, and not part of the formula, but it may help. Research suggests a scent present while you study can help cue that memory later. Keep rosemary (or peppermint) nearby while you learn. Save lavender for the evening; in one study it worsened working memory during testing.

  3. Afternoon

    Set a caffeine cutoff

    Stop caffeine at least 6 hours before bed. Even caffeine taken that early has been shown to cut sleep short, and sleep is when memory is stored.

  4. 90 minutes before bed

    Dim the lights and screens

    Bright screens late in the evening delay the body’s sleep signals. Switch to dim light, night mode, or a printed book.

  5. 1 hour before bed

    Take the PM packet with a light snack

    Then wind down. The PM packet supports restful sleep and works with your body’s own overnight process of retention.* Optional: switch to a calming scent such as lavender while you wind down. In sleep-lab and college-student studies, lavender was linked to deeper sleep and better-rated sleep quality. Turn the diffuser off before you fall asleep.

  6. Lights out

    Keep bed for sleep

    If you’re still awake after about 20 minutes, get up and do something calm in dim light until you feel sleepy, then return to bed. This is a standard part of insomnia programs.

  7. When it counts

    Bring back the scent

    Before the exam, the presentation or the meeting, use the same scent you studied with.

  8. Every day

    Give it time

    Take both packets daily. The studies behind each ingredient ran 4 to 12 weeks, so give the system at least a month.

Rosemary and lavender

From remembrance to research

Two scents, two jobs: rosemary for learning, lavender for winding down.

  1. Antiquity

    Tradition holds that students in ancient Greece wore rosemary while studying for exams. Across Egypt, Greece and Rome, rosemary was placed with the dead as a symbol of remembrance.

  2. About 1600

    In Hamlet, Ophelia says, “There’s rosemary, that’s for remembrance.”

  3. 1937

    French chemist René-Maurice Gattefossé coins the word “aromatherapy.”

  4. 2003

    In a study of 144 healthy adults, those tested in a rosemary-scented room scored better on overall memory than those with no scent. Lavender made working memory worse. Which scent you use matters.

  5. 2005

    In a sleep lab, 31 healthy young adults spent more of the night in deep sleep and felt more vigorous the next morning after lavender was diffused at bedtime, versus a water control. The effect was small.

  6. 2012

    In 20 adults, higher blood levels of 1,8-cineole, rosemary’s main aromatic compound, went with better scores. A small study that shows a link, not proof.

  7. 2015

    In a randomized trial of 79 college students with sleep complaints, those using lavender plus good sleep habits rated their sleep quality better than those using sleep habits alone.

History is why people noticed these scents. Research is why we’d specify them.

Considering: the scents that were studied

We don’t offer scents yet. We’re considering offering the same types of oil used in the research, a cineole-rich rosemary for learning and a true lavender for the evening, each tested batch by batch like everything else we make. Would you want them included?

Adds you to the founding list. Essential oils aren’t for everyone: not recommended during pregnancy, with epilepsy, or around young children and pets.

The research behind the routine

Each habit above comes from published research in people. These studies are about the habits, not about Cellavara.

Roediger & Karpicke, Psychological Science, 2006

Students who practiced recalling a passage remembered more of it a week later than students who spent the same time rereading it.

Herz, Memory & Cognition, 1997

A distinctive scent present while learning and again at testing improved recall, compared with no scent cue.

Moss et al., International Journal of Neuroscience, 2003

144 healthy adults. A rosemary-scented room improved overall memory scores versus no scent; lavender worsened working memory.

Moss & Oliver, Therapeutic Advances in Psychopharmacology, 2012

20 adults. Higher blood levels of 1,8-cineole, rosemary’s main aromatic compound, went with better scores on mental arithmetic tasks. Small and correlational.

Rasch et al., Science, 2007

A scent present while learning, and again during deep sleep, improved next-day recall of what was learned.

Goel et al., Chronobiology International, 2005

31 healthy adults aged 18–30 in a sleep lab. Lavender at bedtime increased the share of deep sleep and next-morning vigor, versus water.

Lillehei et al., Journal of Alternative and Complementary Medicine, 2015

79 college students with sleep complaints, randomized. Lavender plus sleep habits improved rated sleep quality and daytime fatigue more than sleep habits alone.

Drake et al., Journal of Clinical Sleep Medicine, 2013

400 mg of caffeine taken even 6 hours before bed reduced total sleep by more than an hour.

Chang et al., PNAS, 2015

Reading on a light-emitting screen before bed suppressed melatonin, made it take longer to fall asleep, and left people less alert the next morning, versus a printed book.

Diekelmann & Born, Nature Reviews Neuroscience, 2010

A review of how sleep, especially deep sleep, consolidates newly learned information into long-term memory.

Common questions

What if I miss a packet?

Skip it and continue the next day. Don’t take two of the same packet at once.

Can I take the AM packet with coffee?

Yes, as long as you keep your caffeine cutoff. The AM packet has no added caffeine; its cocoa extract has small natural amounts.

Do I need the scent?

No. It’s an optional habit that costs nothing. The formula works the same either way.
