Catuaba is a medium-sized tree found in the Amazon forest in the northern part of Brazil. In Brazilian herbal medicine, catuaba bark is considered a central nervous system stimulant with aphrodisiac properties and a bark decoction is used for nervousness, poor memory, and sexual weakness.
The statue is located on the peak of the 700 metre tall Mount Corcovado, Rio de Janeiro, Brazil. The statue was created by French Sculptor Paul Landowski and built by the Brazilian engineer Heitor da Silva Costa, in collaboration with the French engineer Albert Caquot.
Designed and sculpted by Thomas Ball and erected in 1876, the monument depicts Abraham Lincoln in his role of the Great Emancipator freeing a male African American slave modeled on Archer Alexander. The ex-slave is depicted on one knee, with one fist clenched, shirtless and shackled at the president's feet.
