Isatis is an herb. The dried leaf and root have been used as medicine since ancient times. Isatis is used to treat the common cold and other infections of the nose, throat, and sinuses (upper respiratory tract infections), as well as infections of the glands that make saliva (parotitis). It is also used for encephalitis, a swelling of the brain that is usually caused by infection; a liver disorder (hepatitis); pockets of infection (abscesses) in the lungs; digestive tract infections including dysentery and acute gastroenteritis; prostate cancer; and AIDS/HIV. Isatis is applied directly to the skin for a skin condition, psoriasis. Some people also take isatis by mouth for this condition.
