Medicinal Plants of the Amazon Rainforest

By Lucy
The Amazon rainforest is home to a diversity of medicinal plants. Here are some of the many.
The cocoa tree produces more than 150 chemicals in its leaves, seeds, fruit, and bark. The Olmecs, Mayans, and Aztecs used parts from the tree to treat anxiety, fever, fatigue, and coughs. Five hundred years ago the plant was brought to Europe, where it was used to treat kidney stones and cuts and burns, among other things. Recent research shows that chocolate contains polyphenols, which prevent heart disease.

Annatto/Lipstick tree (Bixa orellana)

Annatto/Lipstick tree has a wide variety of uses. For centuries, rainforest peoples have used the plant for things from insect repellant to lowering blood pressure to love potions. Its traditional uses are backed by recent research. Colombians have used extracts from the plant to treat snakebites. A study in 2000 confirmed this use in mice. Oil from the plant contains carotenoids (plant pigments), one of which, Bixin, protects against UV rays. Annatto is still used today in South America to treat heartburn.
Trumpet tree is widely used in traditional medicine in Central and South America. Every part of the tree is used. The plant treats a diversity of conditions, including respiratory illnesses and rheumatism.

Clavillia (Mirabilis jalapa)

 Clavillia is a perennial herb mainly used to kill viruses, bacteria, fungi, and parasites. This plant has many active compounds like triterpenes, proteins, flavonoids, alkaloids, and steroids. A group of amino acid-based proteins called MAPs protect against plant viruses.
Suma (Pfaffia paniculata) is a large ground vine with an extensive root system. Today, it is considered a tonic and an adaptogen. An adaptogen is a plant that helps the body resists adverse influences by a wide range of factors. In Brazil, suma root is taken to stimulate appetite and circulation, balance blood sugar levels, and enhance the immune system, muscular system, and memory. Suma root has very high saponin content (up to 11%). Saponins have a variety of effects, including lowering blood cholesterol.
