The most important tree for use in resin extraction is the black pine (Pinus nigra), which has the greatest resin content of all of the European coniferous trees, and it was even used as early as by the Romans for this very purpose. [2] These trees are generally best tapped for their resin between the ages of 90 and 120 years old.
Maritime pine bark extract is an extract from the bark of Pinus pinaster which is used as a dietary supplement. It is composed mostly of proanthocyanidins . [ 1 ] Pycnogenol is a trademarked name for a standardized preparation that contains 70% procyanidins .
Pinus nigra is a large coniferous evergreen tree, growing to 20–55 metres (66–180 feet) high at maturity and spreading to 6 to 12 m (20 to 39 ft) wide.The bark is gray to yellow-brown, and is widely split by flaking fissures into scaly plates, becoming increasingly fissured with age.
An extract of maritime pine bark called Pycnogenol bears 65–75 percent proanthocyanidins (procyanidins). [10] Thus a 100 mg serving would contain 65 to 75 mg of proanthocyanidins (procyanidins). Proanthocyanidin glycosides can be isolated from cocoa liquor .
For some species of pine, such as Aleppo pine (Pinus halepensis), European black pine (Pinus nigra) and lodgepole pine (Pinus contorta), the effects of fire can be antagonistic: if moderate, it helps pine cone bursting, seed dispersion and the cleaning of the underwoods; if intense, it destroys these resinous trees.

Probably as a result of this trend, no reports of human studies on the effects of crude yohimbe bark or its extracts on sexual performance can be found in the [scientific] literature... Any discussion of the use of the bark for sexual enhancement thus begins and ends with folklore. In contrast, there is a "fairly rich literature on yohimbine". [9]
The woman, who the Baltimore Banner called "M.," said in an interview that she had reached out to a reporter in 2015, soon after the incident, but stopped communicating out of fear of retaliation.
Pine oil is an essential oil obtained from a variety of species of pine, particularly Pinus sylvestris. Typically, parts of the trees that are not used for lumber — stumps, etc. — are ground and subjected to steam distillation. [2] As of 1995, synthetic pine oil was the "biggest single turpentine derivative."
