The seeds are a source of soap and lubricating oil. Tannin is obtained from the bark. The needles contain a substance called terpene, this is released when rain washes over the needles and it has a negative effect on the germination of some plants, including wheat. Yields turpentine and tar. Oleo-resins are present in the tissues of all species of pines, but these are often not present in sufficient quantity to make their extraction economically worthwhile. The resins are obtained by tapping the trunk, or by destructive distillation of the wood. In general, trees from warmer areas of distribution give the higher yields. Turpentine consists of an average of 20% of the oleo-resin and is separated by distillation. Turpentine has a wide range of uses including as a solvent for waxes etc, for making varnish, medicinal etc. Rosin is the substance left after turpentine is removed. This is used by violinists on their bows and also in making sealing wax, varnish etc. Pitch can also be obtained from the resin and is used for waterproofing, as a wood preservative etc.Wood. Used for construction and carpentry. The timber is used for construction, bridge building, vehicles, furniture, and wood pulp.

Leaf secretions inhibit the germination of seeds, thereby inhibiting the growth of other plants below the tree. This species is sometimes cultivated for its edible seed, there are some named varieties. It is one of the main species utilized for its edible seeds, being gathered from cultivated and wild trees. Large quantities of the seeds are exported as a food crop from N. China. Plants bear cones when they are 3.5 metres tall in Cornwall. Trees are slow growing when young. Growth in the south-east of Britain is generally poor but trees in the west and north are healthy and growing well with average annual height increases of around 25cm and girth increases of 3cm or more. Plants are strongly outbreeding, self-fertilized seed usually grows poorly. They hybridize freely with other members of this genus. The cones do not open, seed is extracted by breaking up the soft scales of the cone.Plants in this genus are notably susceptible to honey fungus.
