What does the research say?
Traditional use
These are traditional uses, not proven treatments.
Contrajerva is one of the plants most often reported as a snakebite remedy in Central America. Of 208 species used for snakebite there, it was one of only nine reported in at least three separate studies.[1]Review or trial
Laboratory & animal research
Lab and animal results show what might be worth studying in people. They don't show that the herb has these effects in humans.
Contrajerva was one of four Yucatán medicinal plants tested in the lab against the Leishmania parasites that cause skin sores. Its extracts weren't among the most active.[2]Study
In short
There's no clinical evidence that it works for snakebite or is safe.
