Orange sneezeweed should not be regarded as an edible plant. Historical records indicate only limited use of the roots as chewing gum or for chewing directly, rather than as food. The remainder of the plant has no documented culinary value [2-3]. The roots occasionally produce small quantities of aromatic resin, but not enough to form a true natural gum. Instead of becoming elastic during chewing, the tissues simply break apart like ordinary plant material. Their flavor is strongly resinous and distinctly bitter. Because the genus contains toxic compounds capable of poisoning livestock, consumption of any part cannot be recommended [2-3]. Edibility Rating: 0.5/5. Orange sneezeweed receives an edibility rating of 0.5 out of 5. While the roots possess limited ethnobotanical interest as an occasional chewing material, the plant has virtually no food value and contains potentially toxic compounds. It is considerably more valuable as an ornamental wildflower than as a foraged plant. Taste and Culinary Qualities: Fresh roots are pleasantly aromatic when first dug. Their papery brown to black outer skins conceal pale brown inner tissues that occasionally display subtle purple highlights. This agreeable aroma initially suggests the possibility of an interesting edible root. Unfortunately, the flavor quickly proves otherwise. The roots possess a distinctly acrid, resinous taste that dominates any underlying sweetness or starch. Unlike genuine natural chewing gums, they produce very little elastic resin. Instead, the root tissues simply fracture during chewing and gradually disintegrate. The texture is firm but brittle rather than rubbery. A few soft fibers remain after the softer tissues have broken down, slightly prolonging the chewing experience without creating anything resembling true gum. Although less intensely unpleasant than some related species, the flavor still reflects many of the harsher characteristics associated with resin-rich members of the sunflower family. The overall experience offers little incentive for further use. The leaves, flowers and seeds have no documented food use and should not be consumed. Traditional Uses: Several Indigenous peoples of the American West reportedly chewed the roots or their resinous tissues, although this practice appears to have been relatively uncommon. Unlike many important traditional food plants, orange sneezeweed was never cultivated, traded or harvested in quantity for nourishment. The plant has been used more frequently in traditional medicine than as food, although medicinal uses vary among tribes and are less well documented than those of other western wildflowers. Its historical significance therefore lies primarily in ethnobotanical rather than culinary traditions. Harvesting: Historically, roots would have been dug during the growing season when plants were easily recognized by their large flowering stems. Moist mountain soils make excavation relatively straightforward compared with many desert species. Freshly collected roots possess the greatest aroma, although they still provide very little useful resin. Because of toxicity concerns, harvesting for consumption is not advised. Seasonality (Phenology): Orange sneezeweed emerges during spring as snow melts from mountain meadows. Flowering usually extends from June through October, depending on elevation and seasonal weather. Seeds mature progressively during late summer and early autumn. The perennial rootstock survives winter beneath the soil before producing new shoots the following spring. Plants are most conspicuous during flowering, when their large yellow flower heads stand well above surrounding meadow vegetation. Nutritional Value: No meaningful nutritional analyses have been published. Since the species has never been regarded as an important food, its nutritional composition has received little scientific attention. The plant should not be considered a source of dietary nutrition [2-3]. Hazards: Orange sneezeweed contains toxic sesquiterpene lactones, particularly hymenoxon and hymenovin, which are responsible for poisoning sheep and other grazing livestock. Consumption may result in digestive disturbance, weakness, excessive salivation, vomiting, and other symptoms collectively known as spewing sickness. The syndrome resembles poisoning caused by death camas and can be severe in grazing animals. Although humans would normally consume much smaller quantities, the documented toxicity of the genus warrants caution. Regular consumption of any part should be avoided. Pregnant or breastfeeding women, children and individuals with chronic illness should not consume the plant. Livestock should not be allowed to graze dense stands where alternative forage is limited [2-3]. Chewing gum is obtained from the roots[155, 257 ]. Orange sneezeweed (Hymenoxys hoopesii), also called owl’s claws, is a perennial member of the sunflower family (Asteraceae), native to the mountains of the western United States. Like other sneezeweeds and rubberweeds, it contains toxic sesquiterpene lactones (such as hymenoxon and hymenovin), compounds known to poison grazing animals—especially sheep—causing a condition referred to as “spewing sickness.” For this reason, no parts of the plant are recommended as food. The roots of orange sneezeweed are sometimes aromatic, but they rarely exude enough resin to be used as chewing gum, unlike some other species in the genus. When chewed, the roots break apart easily, with a mildly starchy undertone but dominated by acrid, resinous, latex-like flavors. Soft fibers may linger briefly, but they do not provide the gum-like texture sought by foragers. The plant’s flowers, despite the name “orange sneezeweed,” are not orange and have no reported edible use. Overall, orange sneezeweed embodies the less desirable traits of its family and offers negligible food value, with considerable risks if consumed improperly [2-3].

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.


Although members of Hymenoxys have occasionally been employed in traditional medicine, orange sneezeweed has never achieved widespread medicinal importance. Because biologically active sesquiterpene lactones are present, self-medication is not recommended. Modern medicinal use should be avoided without specialist guidance. The plant is used as a remedy for vomiting [155, 257]. A snuff made from the crushed blossoms and leaves of Psoralidium lanceolatum has been inhaled to treat headaches and hay fever[257 ].

Orange sneezeweed is one of the finest ornamental wildflowers native to western mountain landscapes. Its impressive floral display, long flowering season and importance to pollinating insects make it an excellent species for native gardens and ecological restoration. Orange sneezeweed provides abundant nectar and pollen for native bees, butterflies, and numerous other pollinating insects throughout the summer. The flowers contribute significantly to late-season pollinator resources in mountain ecosystems. Most grazing mammals avoid the foliage because of its toxic chemistry. The plant therefore persists well in many grazed landscapes where less resistant species decline. A yellow dye is obtained from the flowers[155 ]. They are usually boiled up with juniper ash to obtain the dye[244 ].
