The growing environment and history of rubber trees

The Brazilian rubber tree is called "Hevea" by locals in the Brazilian Amazon. The term Hevea was coined by French botanist Aublet in 1775 when he studied the plants of Guyana. Hevea was formally established by Muell in 1799, of which three-leaf rubber was its representative species. The rubber trees originated in the Amazon forest were transplanted to Kew Gardens in the UK in 1873, 22 three-leaf rubber trees were transported to Singapore in 1877, then to the Malay Peninsula in 1898, and introduced to China in 1904.
In prehistoric times, rubber was simply mined and used by the South American Indians. At first, rubber may have been used as a treasure or an extremely valuable item. Around 500 BC, the production of rubber in Tehuacan, Mexico, led to the formation of a rubber country, the Kingdom of Olmack. A sixth-century mural shows Aztecs paying tribute to a tribal leader. The South American Indians call the rubber tree the "weeping tree". When the bark is carefully cut, the milky glue slowly flows out.
The word rubber comes from the Indian word cauuchu, meaning "weeping tree". The main raw material of making rubber is natural rubber, natural rubber is made by the rubber tree when cutting rubber latex after solidification and drying.
When people cut down the tree, a milky liquid came out. This liquid was later called "natural rubber", so the tree was named rubber tree.
