This perennial herbaceous plant is widely distributed in North America, Europe, Asia, China, Japan, North Korea, and Russia.&nbsp;<em>Tanacetum vulgare</em>&nbsp;L. has been found growing wild in many states of the United States, Europe, and Asia along roadsides, in wastelands, and as a hedge. The chemical composition of the plant and its essential oils is affected by its growing environment and climate. It is well described in the literature for many plants. The plants with sectile leaves grow in Corsica (France), Sardinia, and Sicily (Italy), and some consider them to be a separate species (ssp.&nbsp;<em>siculum</em>). <em>T. vulgare</em>&nbsp;is a 50–100 cm tall perennial herbaceous plant. The stem is straight, branched from the middle, furrowed, glabrous, or slightly pubescent. The leaves are alternate, dark green on top, grayish on the bottom, and pubescent.</p> R.T. Sharipova, Z.U.
