The first written mention of rhododendron was made by the Greek commander Xenophon. Describing the military campaigns in which he participated, Xenophon talks about a fragrant flower, which has intoxicated the whole army. After eating honey made from the pollen of exotic plants, the soldiers fell into unconsciousness and came to their senses only a few days later.

In Chinese medicine, preparations based on the flowers of rhododendron are considered one of the best means to relieve anxiety and normalize the functions of nervous system. A decoction of rhododendron flowers helps to remove excess liquid and toxins from the body. In addition, the positive effect of this decoction relieves inflammation in the throat and reduces coughing.
