Sananga is a traditional medicine made from the roots and bark of the Tabernaemontana undulata plant, which is native to the Amazon rainforest. It is commonly used by indigenous tribes in the region as a way to improve visual acuity, treat eye problems, and facilitate spiritual connection during shamanic ceremonies.

Sananga is typically administered as eye drops, which are made by grinding the plant material into a fine powder and mixing it with water. The drops are then placed directly into the eyes using a small dropper.

The effects of Sananga are said to be powerful and immediate, with many people reporting a burning or stinging sensation upon application. Some users also experience increased clarity of vision, enhanced focus, and a sense of emotional release or purging.

In recent years, Sananga has gained popularity outside of the Amazon region as a natural remedy for eye health and spiritual exploration.
