Properties and Uses– bark contains 4-8% tannin availabilities, which is extracted for the tanning industry. The incomplete combustion of wood is obtained for the preparation of carbon black ink.

Young leaves and tops are used as raw material for preparation of "essence of pine, a product search in medicine and cosmetics. Tree flowers are sought by bees for pollen and propolis hand, the whole summer.
