A tincture is prepared from the leaves, which is used as a remedy for sweating. In patients with tuberculosis with profuse sweating, a tincture at a dose of 15 drops 3 times every day reduces sweating. The greatest effect develops on the 3rd day. After stopping the tincture, the effect is saved from 2 to 15 days. A similar effect of the tincture was also found in patients with fibrous-cavernous pulmonary tuberculosis with debilitating profuse sweating. The drug was administered at a dose of 20 drops per reception 3 times every day for 3 days. Sweating decreased on the 2nd-3rd day. The action of the product after its cancellation lasted from 2 to 10 days.
The most pronounced decrease in sweating was noted in patients with subcompensated forms of tuberculosis; in decompensated forms, the effect of the product was unstable.
In folk medicine, it is used for hemoptysis, to reduce sweating in tuberculosis patients.
