Popular names for Linden are Tilia and Lime. Lime flowers are a popular domestic help for a number of ailments, especially in the treatment of colds and other ailments where sweating is desirable. Active ingredients in the lime flowers include flavonoids (which act as antioxidants), volatile oils, and mucilaginous constituents (which soothe and reduce inflammation). The plant also contains tannins that can act as an astringent. The flowers were added to baths to quell hysteria, and steeped as a tea to relieve anxiety-related indigestion, irregular heartbeat, and vomiting. Tilia flowers are used in colds, cough, fever, infections, inflammation, high blood pressure, headache (particularly migraine), as a diuretic, antispasmodic (reduces smooth muscle spasm along the digestive tract) and sedative.
