Sananga Eye Drops — The Amazonian Vision Medicine Nobody Warns You About

Made from the roots of an Amazonian shrub, Sananga is dropped directly into the eyes — burns intensely for two minutes, and is said to clear vision, focus, and emotional fog. What it is, why we use it, and what to actually expect.

Of all the medicines we offer at our retreats, Sananga is the one that surprises people the most. It looks like a small dropper bottle. It feels, for the first ninety seconds, like fire. And then — for many people — something unexpectedly tender opens.

What is Sananga?

Sananga is a liquid medicine made from the roots and bark of a small Amazonian shrub, most commonly Tabernaemontana undulata (sometimes called Becchete by the Matsés people, or 'becchete becchete' in Yawanawá). The roots are scraped, pounded, soaked in water, and the resulting infusion is filtered into a small dropper bottle. It is a deep amber color, thicker than water, with an earthy bitter smell.

Indigenous Amazonian peoples — particularly the Matsés, Yawanawá, Katukina, and Kuntanawa — have used Sananga for centuries before hunting (to sharpen long-distance vision in the dark forest), before sleep (to clear vivid dreams), and before ceremony (to clear panema, the heavy stagnant energy that prevents deep work). Modern circles use it in the same three contexts.

What Sananga actually feels like

We won't sugarcoat this. Sananga is one of the more physically uncomfortable medicines you will encounter, and the discomfort is concentrated in the first two minutes. Here is the honest sequence:

  1. Two drops are applied to each eye, one eye at a time. You lie back. Eyes closed.
  2. Within 5 seconds: an intense, sharp burning sensation. Tears flow heavily. The pain is real but localized — only in the eyes.
  3. Seconds 30 to 90: peak burn. Many people feel waves of heat or pressure spread from the face into the chest. Some report a strong emotional release — crying that goes beyond the physical tears.
  4. Around 2 minutes: the burn fades quickly. Within 3 to 5 minutes you can open your eyes again.
  5. What follows is striking. Vision is sharper, colors more saturated, contrast deeper. The sense of 'mental fog lifted' is immediate. This clarity often lasts hours.

Why we use Sananga in our retreats

Three traditional reasons, all of which we still find useful:

1. To prepare for ceremony

Sananga before Ayahuasca or San Pedro is said to 'clear the lens' — both literally (visual sharpness) and energetically (mental clarity, emotional readiness). Many participants report that ceremonies feel deeper, visions more coherent, and less time spent fighting the come-up when Sananga is applied an hour or two beforehand.

2. As a stand-alone clearing

Outside of ceremony, Sananga is used as a kind of 'reset.' For people working through depression, mental fog, brain fatigue, or low motivation, a short Sananga ceremony followed by an hour of rest in nature often produces a noticeably brighter mood for several days.

3. For the eyes themselves

Traditionally, Sananga has been used for early-stage vision issues — eye strain, blurriness, mild glaucoma, conjunctivitis. We do not make medical claims and we do not replace ophthalmology. But many participants report sharper distance vision and reduced eye strain after several sessions, particularly people who spend long days in front of screens.

Who shouldn't use Sananga

  • Pregnancy or breastfeeding
  • Recent eye surgery (LASIK, cataract, etc.) — wait at least 6 months
  • Acute eye infection or injury
  • Severe dry-eye conditions
  • Children
  • Anyone with active glaucoma should consult their ophthalmologist first

What we've seen

Sananga is the medicine that comes up most often in our 6-month follow-ups when we ask participants which medicine they're using on their own at home. People take small bottles back with them and use it once a week, before bed or before meditation. It's the gentlest doorway in the apothecary — and the one with the steepest first impression.

It is included in our retreat preparation protocol on the morning of ceremony day for anyone who wants it. It is also available on its own as part of a one-on-one session with Gabriel.
