"Grindelia robusta""Grindelia camporum" is a species of flowering plant in the daisy family known by the common names Great Valley gumplant and Great Valley gumweed. It is native to
California andBaja California , where it can be found in a number of habitats. Its range may extend intoNevada . This hardy plant readily grows in disturbed and altered areas such as ditches and roadsides. It is a gangly weedlike perennial topping two meters in maximum height. Its erect, branching stems are lined with many stiff, wavy-edged, serrated leaves 2 to 3 centimeters long. Atop the stem branches areinflorescence s of a single large flower head up to 3 centimeters wide. The head is a vaguely thistlelike cup of green clawlike phyllaries that bend downward. The center of the head is filled with yellow disc florets and there are usually many yellow ray florets around the circumference. The flower head fills with a copious white exudate, especially during the early stages of blooming.Medicinal Use
Grindelia camporum is used in Herbal Medicine to treat bronchitis, asthma, coughs, and any condition where phlegm in the airways impedes respiration. Active constituents include resins, phenolic acids, volatile oils, flavonoids, and triterpene saponins. It is thought to act by desensitising the nerve endings in the bronchial tree and slowing the heart rate. It is also indicated for cystitis, and externally for burns, poison ivy rash, dermatitis, eczema, and skin eruptions. As the active principle is excreted via the kidneys, large doses may cause renal irritation.
