It has been used in many ways, not only as fuel source, fodder (for livestock) and timber but the trees also yield edible nuts for human consumption or for folk medicine uses.

[7][10][8] They are very, small flowers, in male catkins which are 2–4 cm (0.8–1.6 in) long and also female spikes,[4] and they appear before the leaves.

[6][4] The husk is spiny and has green maturing to deep brown shaded bracteoles (flower-leaves).

[11] Corylus jacquemontii generally resembles the Turkish tree Hazel (Corylus colurna),[6][5] but C. jacquemontii is a smaller tree, has thinner bark, larger leaves, is less glandular and has less fleshy husks, and also fewer nuts per cluster.

[16][17] Frequent nut intake is associated with low risk of cardiovascular disease and cancer (Surh 2003;[18] Hertog et al. 1993;[19] Ness and Powles 1997).

[9] The Latin specific epithet jacquemontii refers to the French botanist and geologist Victor Jacquemont (1844–1912).

[3][25] Closely allied to C. colurna, and was once considered to be no more than a sub-species by some botanists,[5] or a synonym,[26] before being later accepted as a separate species.

[27][28] It was found that Corylus jacquemontii diverged from C. avellana about 4–6 Ma (million years ago) in the nrDNA trees.

[25] Corylus jacquemontii is native to temperate and tropical areas between Europe and Central Asia.

[1][31] It is grows in moist oak forests,[1] and shrubberies,[32][8] and it is found at altitudes between 1,800 and 3,000 m (5,900 and 9,800 ft) above sea level,[4][8][32] in the upper montane zones.

[1] Corylus jacquemontii is used in many ways, not only as fuel (for house fires), fodder (for livestock) and timber (including logging,[1]) but the trees also yield edible nuts for human as well as wildlife consumption.

[26] The edible nuts,[14][4] of C. jacquemontii and Corylus colurna are often consumed by local human populations.

[13][38][39] In the 1860s, Indian forester Hugh Cleghorn, recorded that nuts from this species were sold in the bazaar in Shimla, Himachal Pradesh, India.

[9] After falling to the ground they can also eaten by small rodents like pica (such as Ochotona macrotis), flying squirrel, rats and even by the Himalayan brown bear (Ursus arctos isabellinus) as reported by Vaidya (2003).

[40] The leaves and young shoots are lopped (down) for use as cattle fodder,[9] and as a fuel source along with maple (Acer spp.)

[27] It is used in folk medicine,[9][10][41] such as a massage oil (made from the seed) of the species is used for relieving muscular pain.

[13] This species is cultivated for its edible seed in Asia,[32][1][4] and then nuts are distributed worldwide, but mainly to countries such as Turkey, Italy, Spain, France, Greece, India, Iran, Azerbaijan and China.

[50] Specimen trees have frequently set fruit (nuts) in Kew Gardens, UK.

[53] Many of the forests where C. jacquemontii is a native species, are being rapidly degraded through over-exploitation (of resources) and also habitat destruction, due to the search for fodder, fuel, food and medicinal purposes and other uses.
