Grindelia squarrosa, commonly known as curlycup gumweed or gumplant, is a perennial flowering plant species belonging to the family Asteraceae. It is native to North America and can be found across western and central parts of the continent, particularly in the Great Plains and Rocky Mountains regions.
The plant typically reaches a height of 1 to 3 feet and has rough, wiry stems covered with a thick white or gray coating of hairs. It produces bright yellow flowers in summer, with ray flowers surrounding a central disc of smaller tubular flowers. The flowers are often described as resembling small daisies and are arranged in clusters at the ends of the stems.
Grindelia squarrosa is known for its pungent odor reminiscent of balsam or turpentine and its sticky resinous sap, which has led to its alternative common name, gumplant. The plant has been traditionally used by Native American tribes for its medicinal properties, particularly as a topical treatment for skin irritations, burns, and insect bites.
In modern times, Grindelia squarrosa is also recognized for its potential therapeutic uses. The plant contains several bioactive compounds, including terpenes and flavonoids, which have demonstrated anti-inflammatory, antimicrobial, and analgesic properties in scientific studies. Due to these potential benefits, extracts of Grindelia squarrosa are now sometimes incorporated into natural remedies, ointments, and creams for skin conditions such as eczema and psoriasis.
Overall, Grindelia squarrosa is a herbaceous flowering plant possessing distinctive physical characteristics, a strong aroma, historical significance in traditional medicine, and potential applications in modern natural remedies.
