In short

Mix 1 gram of Katukina sananga root powder to 7 ml of sterile water, stir, let the sediment settle overnight, then filter and bottle. Work clean, make small batches, and keep it refrigerated. Sananga is a traditional Amazonian eye preparation — this guide is practical, not medical, advice.

The basics

Why Make Sananga at Home?

Sananga is a traditional Amazonian eye preparation, made by the Katukina from the root bark of Tabernaemontana sananho and applied as drops. If fresh sananga is hard to get hold of, or you simply prefer to prepare your own, making it at home from the dried root powder gives you a fresh, potent supply whenever you need it — and full control over cleanliness and strength.

What You'll Need

Sananga root powderKatukina root-bark powder, always measured in grams.
Sterile drinking waterMeasured in millilitres.
A large glass jarScrew or rubber-sealed lid — glass, not plastic.
Glass dropper bottlesOptional, for storage.
A fine filterCheesecloth, a nut-milk bag, or a paper coffee filter.
A funnel + two saucepansOne pan for the water, one for sterilising the jars.

Sterilise Your Equipment

Cleanliness matters most here, because the finished drops go in the eye. Sterilise the jars and droppers by boiling for 5 minutes, then let them cool in the hot water before removing and air-drying. (For general guidance on sterilising, the CDC's hygiene FAQ is a good reference.)

Prepare the Water

Boil your clean drinking water for 1 minute — or 3 minutes if you're above 2,000 m (6,500 ft) altitude — then let it cool slightly. (See the CDC on boiling water.)

The formula

The Sananga Recipe

One clean ratio does it:

Universal formula

1 g sananga powder : 7 ml water

This yields roughly a 50% sananga solution after settling and filtering. Example: 10 g powder + 70 ml water → about 35 ml of finished sananga.

Keep batches small — only make what you'll use in 3–4 weeks.

Step by Step

1. CombineAdd the sananga powder and just-boiled water to your sterilised jar.
2. StirStir well every 5 minutes for 30 minutes to extract the sananga.
3. SettleCover loosely and rest 6 hours or overnight in the fridge, so the sediment settles.
4. DecantCarefully pour off the liquid, leaving the sediment behind.
5. FilterPass it through a paper coffee filter, cheesecloth or nut-milk bag — use a funnel, or stretch the filter over the jar with a rubber band.
6. StoreBottle the finished sananga in sterilised dropper bottles or a clean glass jar, and keep it in the fridge.

Safety

Sananga produces an intense sting on application that passes after a minute or two — that's expected. Because the drops go directly in the eye, hygiene is essential: sterilise everything, use fresh sterile water, keep the finished sananga refrigerated, and discard any batch that looks or smells off. If you wear contact lenses, remove them first, and speak with a qualified professional before using sananga, especially if you have any eye condition.

Make-Your-Own Sananga FAQ

What's the sananga powder-to-water ratio?+

Use 1 gram of sananga root powder to 7 ml of sterile water. After settling and filtering, that yields roughly a 50% solution — for example, 10 g powder with 70 ml water gives about 35 ml of finished sananga.

How long does home-made sananga keep?+

Make small batches and use them within 3–4 weeks, kept refrigerated in a sterilised glass bottle. Discard any batch that changes colour or smell.

Why does it have to be so clean?+

Because sananga is applied directly to the eye, sterility matters: boil your jars and droppers for 5 minutes and use freshly boiled water, so nothing unwanted ends up in the drops.

Does home-made sananga sting?+

Yes — a strong, brief sting on application is normal and part of the traditional experience; it typically eases within a minute or two.
