At The Scripps Research Institute in Florida, researchers have undertaken a study of Tabernaemontana divaricata, also known as crepe jasmine, a tropical flowering plant that has long been used in traditional medicine in China, India and Thailand. Natural practitioners in these countries prescribe various parts of the plant (from flowers to leaves, roots and bark) to heal wounds, fight toothaches and treat skin diseases, fever and pain. When it comes to pain, it turns out that one of the most promising elements in crepe jasmine is conolidine, an extremely rare constituent of the stem bark of Malayan T. divaricata.
