Cannabis may be the rock star of the medicinal plant world, but it’s certainly not the only plant to contain healing terpenes and cannabinoids. The Lemonbush, Lippia javanica, a common shrub in East and Southern Africa, has several terpenes and cannabinoids of medicinal benefit. Also known as Fever tea (or Zumbani, in the local Shona language), the Lemonbush is part of the Verbena family. Its fragrant leaves make a tasty herbal tea, and have long been consumed for their multiple health benefits. In this episode (his second on this plant), Gus, the African Plant Hunter, delves deeper into some of its medicinal compounds: Myrcene (subject of the fabled “Mango Myth”), Linalool (the sedative compound in lavender) and Caryophyllene (a potent anti-inflammatory). Sadly Lemonbush has not yet been put through the regulatory hoops for sale in the West, so if you want to try it, you’ll have to travel to Africa to do so!
