A 2012 Cochrane Review, updated in 2020, Robertson et al. reviewed the evidence on the efficacy of pine bark extract for treating a wide range of complaints (including asthma, children with ADHD, blood pressure, pain in CVI, reducing fasting blood glucose, osteoarthritis of the knee, cognitive failure in those with traumatic brain injury) and in all cases failed to find evidence to support the ...
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.
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.

Close up of longleaf pine bark. The bark is thick, reddish-brown, and scaly. [6] [7] The leaves are dark green and needle-like, and occur in bundles of mainly three, sometimes two or four, especially in seedlings. They often are twisted and 20–45 centimetres (7 + 3 ⁄ 4 – 17 + 3 ⁄ 4 inches) in length.
This drying is generally done in the shade to preserve its characteristic yellow color. This process can be quickened by simply baking the bark at a low temperature for several hours. [20] Botanist J. Morton suggests using a dose of 10–30 grains, dissolved in water, or 0.6–2.0 cc for fluid extract.
