"Slash pine has two different varieties, var.elliottii and var.densa. Historically, slash pine has been an important economic timber for naval stores, turpentine, and resin." [[https://en.wikipedia.org/wiki/Pinus_elliottii|wikipedia]]

The major components of turpentine of P. elliottii var. elliottii were α-pinene (56.6%), camphene (0.6%), β-pinene (35.6%), myrcene (0.3%), dipentene (1.5%), β-phellandrene (3.3%), p-cymene (0.2%), and methyl chavicol (0.7%). \\

Major monoterpene constituents of P.elliotti oleoresine were α-pinene (3-95%, mean 30%), β-pinene (0-76%, mean 44%), myrcene (0-60%, mean 7%), limonene (0-81%, mean 7%) and β-phellandrene (0-69%, mean 11%). "Percentages of trees having high amounts of each monoterpene varied greatly among seed origins and revealed distinctive geographic patterns." \\

"According to Morton, turpentine has long been used internally for catarrh, chronic bowel inflammation, colds, gonorrhea, leucorrhea, rheumatism, and various urinary complaints... Pine tar has been used for mainy ailments in the past, but letaely it is prescribed only for external use in chronic and parasitic skin diseases..." \\
