Yerba Santa translates from Spanish into 'sacred herb' or 'holy herb'. The herb is often used for medicinal purposes related to the respiratory system. The herb comes from the Eriodictyon Californicum plant which is also known as mountain balm. The plant is native to California and Oregon. This smudge stick can be used just like a traditional white sage smudge stick as it is thought to help clear and purify spirits.10cm
