Botanical Overview
Mexican Pinyon (Pinus cembroides) is a species in the Pinaceae family. The pine family (Pinaceae) includes coniferous trees with needle-like leaves arranged in bundles or spirally along the branches. They produce male and female cones and are wind-pollinated. The resin contains turpentine and other terpenes with traditional medicinal uses for respiratory conditions. Although comprehensive ethnobotanical records are limited, phytochemical studies have identified 16 compounds in this species, suggesting potential medicinal value.
General Description
It is a small pine growing to about 20 m (66 ft) with a trunk diameter of up to 50 cm (20 in). It is native to western North America. It grows in areas with low levels of rainfall and its range extends southwards from Arizona, Texas and New Mexico in the United States into Mexico. It typically grows at altitudes between 1,600 and 2,400 m (5,200 and 7,900 ft). The seeds are large and form part of the diet of the Mexican jay and Abert’s squirrel. They are also collected for human consumption, being the most widely used pine nut in Mexico.
