Nevada biscuitroot is a valuable native food plant that supplied Indigenous peoples with nutritious spring roots across much of the Great Basin. While it is somewhat less productive than the largest biscuitroot species, it remains an excellent wild edible for experienced foragers who can confidently distinguish it from poisonous look-alikes [2-3]. The roots are edible, and some references also report the leaves and young shoots as edible. As with all species in the Lomatium genus, the roots should be soaked or cooked before eating to reduce naturally occurring furanocoumarins. Accurate identification is essential because biscuitroots closely resemble the deadly spotted hemlock (Conium maculatum) before fruit develops [2-3]. Edibility Rating: 4 out of 5 – A good edible native root with a history of traditional use, although generally considered less important than the very best biscuitroot species [2-3]. Taste and Preparation: The thickened roots are rich in starch and were traditionally roasted, baked, boiled, or dried for storage. Like other biscuitroots, they develop a pleasant, parsnip-like flavor after cooking. Fresh roots may have a mild aromatic character typical of the parsley family, while cooking softens the texture and improves palatability [2-3]. Seasonality (Phenology): Flowering typically occurs from April to June, depending on elevation and seasonal rainfall. Roots are usually harvested in spring while the plant is actively growing. Traditional Uses: Native American peoples throughout the Great Basin gathered Nevada biscuitroot as a dependable spring carbohydrate source. People could eat the roots fresh after cooking or dry them for later use, providing an important food before many summer plants matured [2-3]. Safety: Although traditionally eaten, Nevada biscuitroot contains furanocoumarins, compounds that can cause skin irritation and increase sensitivity to sunlight in susceptible individuals. Cooking or soaking helps reduce these compounds. Extreme care must be taken to distinguish it from spotted hemlock, one of North America's most poisonous plants [2-3].

Lomatium nevadense has traditional ethnobotanical uses, specifically by Indigenous peoples of the American Southwest and Great Basin, though it is less commonly studied or used commercially for medicine than its relative Lomatium dissectum. Respiratory and Viral Uses: Indigenous groups historically used the roots of Lomatium nevadense to treat viral respiratory infections, mirroring the wider traditional use of the Lomatium genus for coughs, colds, and lung ailments.

The early-season flowers provide nectar and pollen for native bees, flies, and other pollinating insects. The foliage may also be browsed by wildlife.
