Tormentil

About

Tormentil, which has long been called kalhan in the Carpathians, is a low perennial herb 15–50 cm tall. It grows throughout Ukraine: in pine and mixed forests, on clearings, dry meadows, and the edges of swamps. It also occurs in mountain meadows and polonynas, where its thin stems stretch among the grasses.

The flowers are solitary, yellow, 7–11 mm in diameter, on long thin pedicels. A distinctive feature that makes Tormentil easy to recognize: the flower almost always has four petals with a notch at the tip, while most related species have five. The leaves are trifoliate, consisting of three serrated leaflets, and the pairs of large leaf-like stipules make them resemble palmate leaves. It blooms from May to September.

Underground, the plant has a thick, bulbous, woody rhizome, which is reddish when cut. It is very rich in tannins—significantly more than is found in herbaceous plants. In the past, it was even used to obtain a red dye for leather. The plant has many folk names: besides kalhan, it is called balaban, derev'yanka, pyatypal or zavyaznyk.

In Carpathian villages, the rhizome of kalhan is traditionally dried and used for herbal teas and homemade bitter tinctures. The plant's reserves are significant but are decreasing due to the drainage of swamps. Remember that in reserves and protected areas of national parks, collecting and digging up plants is prohibited.
