Linden leaf is used for colds, stuffy nose, sore throat,
breathing problems (bronchitis), headaches, fever, and to make it easier to
bring up phlegm by coughing (as an expectorant). It is also used for rapid
heartbeat, high blood pressure, excessive bleeding (hemorrhage), nervous
tension, trouble sleeping (insomnia), problems with bladder control
(incontinence), and muscle spasms. Linden leaf is also used to cause sweating
and increase urine production.
