Traditional Uses: Sweet Flag is presently classified as an unsafe herb for internal usage by the FDA. It has been used for centuries, however, in Ayurvedic medicine as a renowned rejuvenator of the nervous system for conditions of anxiety, hysteria, insomnia, neurasthenia, and other nervous complaints. It is useful in all conditions of excess vata and is known to enhance awareness and improve memory. A decoction of the root acts as a carminative removing discomfort caused by excess intestinal gas. According to Duke, Orientals use the root decoction in bronchitis and as an aphrodisiac. A small piece of the root is chewed to overcome mental fatigue. The skin of the root is hemostatic. It has been used in dyspepsia, dysentery, headache, gout, and rheumatism. The juice of the root is applied to boils, carbuncles, and painful joints. In large doses it is emetic.
