Licorice Root Tea and Root Tisanes — Deep Earth Flavours
Licorice root's use as both medicine and flavouring dates to ancient Egypt (found in Tutankhamun's tomb), ancient China (Shennong's Classic of Materia Medica, 2700 BCE), and ancient Greece (where Theophrastus described it in 300 BCE). Traditional Chinese Medicine uses licorice root (甘草, gāncǎo) as a 'harmonising' ingredient in over 50% of Chinese herbal medicine formulas. European licorice root cultivation developed in the Middle Ages in Calabria (Italy) and Yorkshire (UK). The global herbal adaptogen market, driven by ashwagandha, valerian, and similar roots, reached USD 8.5 billion in 2023.
Root tisanes occupy a distinct category within herbal infusions — beverages brewed from dried roots rather than leaves or flowers, producing richer, more body-forward, often naturally sweet infusions that require longer steeping times and higher temperatures than leaf-based herbal teas. Licorice root (Glycyrrhiza glabra) tea is the category's defining example — intensely sweet (glycyrrhizin is 50 times sweeter than sugar) with distinctive anise-like flavour, consumed across China, the Middle East, and Europe as both a flavouring agent and medicinal beverage. Other significant root tisanes: dandelion root (earthy, bitter, coffee-like), burdock root (woody, sweet), valerian root (musky, sedative), ashwagandha root (earthy, bitter, Ayurvedic adaptogen), and ginger root (warming, spicy, anti-inflammatory). Root tisanes are the most medicinally serious herbal beverage category — licorice root has documented interactions with certain medications; valerian is a recognised mild sedative; ashwagandha is one of Ayurveda's most studied adaptogenic compounds.
