Global Perspectives on the Medicinal Potential of Pines (Pinus spp.)

Abstract

Pines are edifying woody species for forest habitats, having crucial importance for ecosystems in both cold (boreal or mountainous) and warm (Mediterranean and tropical) areas. Pine trees include about 120 species, many of which have had an important ornamental role. Despite their ecological importance, many pine forests are threatened by increasing deforestation and habitat degradation, leading to progressive declines in species distribution and genetic diversity worldwide. Humans have used pine wood since the Stone Age, gradually discovering their outstanding medical properties. This review synthesizes global knowledge on the medicinal potential of pines. Using a comprehensive literature survey of major international scientific databases, we evaluated documented traditional and modern medical applications across all regions where pines naturally occur. The vast majority (86) of pine species were described as having medicinal properties, and the uses of the main pine species in representative regions of all continents supporting forest vegetation were examined. Various organs or secretions (needles, branches, bark, buds, cones, seeds, pollen, roots, wood, sap, resin, pitch, etc.) have been used to prevent or treat numerous diseases or to strengthen the organism. Their reported therapeutic activities include antioxidant, antimutagenic, antitumor, antimicrobial, skin-protective, antinociceptive, anti-inflammatory, neuroprotective, antiallergenic, laxative, circulatory-enhancing, antihypertensive, anti-atherosclerotic, anti-aging, and antithrombotic effects. Given the remarkable phytochemical diversity and broad pharmacological value of these species, the conservation of pine genetic resources and natural habitats is urgent. Protecting these species is essential not only for maintaining ecosystem resilience but also for preserving their substantial pharmaceutical and industrial potential.
