Tournefortia arborea BlancoHeliotropium foertherianum is a species of flowering plant in the borage family, Boraginaceae. It is native to tropical Asia, including southern China, Madagascar, northern Australia, and most of the atolls and high islands of Micronesia and Polynesia. Common names include Tree Heliotrope, Velvet Soldierbush and Octopus Bush. It is a shrub or small tree typical of littoral zones reaching a height of 6 m (20 ft), with a similar spread.

Taxonomy
Originally published as Tournefortia argentea, it was transferred to Argusia argentea, and remained under that name until recently. It was subsequently restored to Tournefortia before being transferred into Heliotropium under a new name in 2003.[2][3]
Uses
Flowers
Wood
The wood of H. foertherianum is commonly used to make handicrafts, tools, and, in Polynesia, frames for swim goggles. Due to its availability, H. foertherianum is used as firewood, and has become rare in some areas as a result.[4]
Medicinal
Octopus bush is used in many Pacific islands as a traditional medicine to treat ciguatera fish poisoning, which is caused by powerful ciguatoxins produced by microscopic Gambierdiscus algae. Scientists from the Institute of Research for Development (IRD) and the Louis Malarde Institute in French Polynesia and Pasteur Institute in New Caledonia are researching the plant chemistry and believe that the plant possesses a molecule similar to rosmarinic acid, which is known for its antiviral, antibacterial, antioxidant and anti-inflammatory properties.[5] The researchers think rosmarinic acid may remove the ciguatoxins from their sites of action, as well as being an anti-inflammatory.
