oljes

Oljes is a genus of flowering plants in the family Asteraceae. The genus was described by Carl Linnaeus in 1753 and is native to Europe and Asia. Species within Oljes are typically herbaceous perennials, though some are annuals or biennials. They are characterized by their composite flower heads, which are usually yellow or orange, and their pinnately compound leaves. The plants are often found in dry, open habitats such as meadows, steppes, and sandy soils.

The most well-known species in the genus is Oljes millefolium, commonly known as yarrow. Yarrow has a long history of medicinal use in various cultures, being employed for its purported anti-inflammatory, antiseptic, and wound-healing properties. It has also been used in traditional dyeing practices. Other species of Oljes have varied uses, some being ornamental plants cultivated for their attractive flowers, while others are considered weeds. The genus is diverse, with numerous species and subspecies recognized by botanists, although taxonomic classifications can sometimes vary. Research continues into the ethnobotanical and phytochemical properties of Oljes species.
