    It is established that the leaves of rhododendrons have an effect on the heart, similar to that of the preparations of the digitalis group.

    Experimental studies have revealed that rhododendron preparations( tincture, infusion and novogalene preparation of Pontic Rhododendron Rhododenzide, which is an aqueous solution of the active principles of the plant) increase the tone of the heart muscle, increase the amplitude and reduce the frequency of contractions of the heart, do not significantly change blood pressure andhave a clear diuretic effect. Due to the rapidity of the onset of action and the lack of cumulative properties, rhododenzide is closer to strophanthin, but unlike it, it decomposes little in the gastrointestinal tract. The greatest biological activity is possessed by preparations from the rhododendron of the Pontic and the Caucasian, of which the former is less toxic than the second.

    action in prescribing them to patients with cardiovascular insufficiency.

The cumulative properties of rhododendron preparations do not possess.

    In folk medicine, infusion of leaves is used for fever, epilepsy, headaches, insomnia, irritability, and also as a cardiac and diuretic. In addition, there was a favorable effect of infusions with rheumatism, gout, dysentery, acute and chronic colitis.
