Sananga is an herbal "drug" made from the root of an Amazonian shrub, Tabernaemontana undulata, and contains alkaloids similar to iboga.
The herbal "drug" has been used by indigenous groups in the Amazon for thousands of years to dilute panema, which is believed to be the energetic force behind disease. It was also used to sharpen vision before hunting in the rainforest.
The root is crushed and made into a tan liquid that is applied through eye drops. It causes intense burning for 3-15 minutes, making the world view more vivid and colorful.
On a physical level, Sananga is associated with treating eye infections, sinusitis, chronic headaches, glaucoma, cataracts, astigmatism, conjunctivitis, dry/red eyes, photophobia, and keratoconus. On an energetic and spiritual level, decalcifying the pineal gland helps open the third eye and emotionally balance the user.
Sananga can be before or after Kambo or other medicines to help remove detox residue from the eyes.
