Application
The monks' monastery medicine describes the felt-leafed royal jelly as effective against constipation, diarrhea, malaria and hemorrhoids.
Superstition says that if you rub your hands with juice or flowers, you can catch fish with your bare fists.
The flowers can dye textiles yellow, and the stems and leaves have been used as fuses, candle wicks and for torches.
Royal jelly is still used for respiratory diseases. It is the plant's expectorant properties that make it useful for hoarseness, bronchitis, asthma and whooping cough. Royal jelly is diuretic and soothing and relieves inflammation in the urinary system.
