Osha root is a wildcrafted herb native to the Rocky Mountain area and has historically been used by the Native Americans for respiratory support. It's called Tie Da Yin Chen (also spelled Die Da Yin Qin). A strong herb for exterior Wind patterns and Bi Syndrome. It is of similar species as Gao Ben, but decidedly stronger in action. The roots of the plant contain camphor and other compounds which make it one of the best lung-support herbs in America. One of the main benefits of Osha root is that it helps increase circulation to the lungs, which makes it easier to take deep breaths. Also, when seasonal sensitivities flare up your sinuses, Osha root, which is not an actual antihistamine, does produce a similar effect and may be help calm respiratory irritation. The magical use of Osha root comes from northern Native American tribal traditions where it is viewed as having great power in luck and is often carried as a lucky talisman. When burned it produces a warm and spicy aroma which is believed to purify the air in much the same way smudge sticks are used. Because of its power in good luck it is also thought to guard against negative or harmful influences and energies.
