Machaeranthera gymnocephala

Machaeranthera gymnocephala, also known as White Yarrow or White Fleabane, is a flowering plant species in the daisy family (Asteraceae).

It is native to the southwestern United States and northern Mexico, and has been used in traditional medicine for its medicinal properties, which include anti-inflammatory, antiseptic, and antispasmodic properties.

The plant's medicinal properties are attributed to the presence of flavonoids, terpenoids, and sesquiterpenes, which have been shown to have various health benefits, including reducing inflammation, promoting wound healing, and alleviating menstrual cramps.

The plant can be prepared for medicinal use through herbal preparations such as teas, infusions, and tinctures, although its use should be guided by a healthcare professional.
