White sage is an evergreen perennial shrub that is native to the United States and Mexico. Smudging, the burning of the dried leaves, is an ancient Native American tradition where white sage is used to cleanse and purify a space or a person of unwanted or negative energies. White sage can also be used as a tea for colds, sore throats, sinus congestion, indigestion, or heavy menstruation. It is also valuable as a culinary spice, with a similar flavour to garden sage. Sage can reduce all bodily secretions (mucous, breast milk, sweat), so avoid in pregnancy and lactation.
