Araroba is a term used to refer to a type of resin that is derived from the Brazilian tree, Andira araroba. This resin was historically used for medicinal purposes due to its ability to treat diseases like syphilis. While the term "araroba" is relatively uncommon today, there are several other synonyms that can be used to refer to this resin. These include "goa powder," "Bahia powder," and "Pernambuco powder," which are all named after regions in Brazil where the resin was harvested. Additionally, "chrysarobin" is another synonym that is frequently used to refer to this natural substance.
