The Punicaceae family includes two species of trees and deciduous bushes, the best-known being "punica granatum". The Latin name used today ("punica granatum") comes from the Romans, who called the fruit "punicum malum" (Punic apple), while "granatum" meant "full of seeds". It has been known since ancient times for its reddish fruits with their edible pulp, which were greatly enjoyed by travelers and caravanners for their water content, their sweet and bitter taste, and their long preservation, thanks to the tough outer skin.
Pracaxi (or pracachy) grows naturally in Amazonia and, like all legumes, its roots are able to "fix" nitrogen. This particular characteristic enables it to regenerate easily in poor soil, while enriching the ground at the same time. It is often used in traditional medicine, especially to promote healing.
