Camas Lily and Pollen

Camas has an edible bulb eaten for millennia by northwest Native Americans. This onion-like delicacy has an indigestible starch that turns to sugar; traditionally it was cooked in an earthen oven for one to two days. Climate change causes increased pollen from grasses and many other plants, leading to more asthma and allergies.
